How to create image slideshow using JavaScript
 
17:13
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/how-to-create-image-slideshow-using.html In this video, we will discuss creating a simple image slideshow using JavaScript. We will be using setInterval() and clearInterval() JavaScript methods to achieve this. We discussed these functions in detail in Part 34 of JavaScript Tutorial. When you click "Start Slide Show" button the image slideshow should start and when you click the "Stop Slide Show" button the image slideshow should stop. For the purpose of this demo we will be using the images that can be found on any windows machine at the following path. C:\Users\Public\Pictures\Sample Pictures At the above location, on my machine I have 8 images. Here are the steps to create the image slideshow using JavaScript. Step 1 : Open Visual Studio and create a new empty asp.net web application project. Name it Demo. Step 2 : Right click on the Project Name in Solution Explorer in Visual Studio and create a new folder with name = Images. Step 3 : Copy the 8 images from C:\Users\Public\Pictures\Sample Pictures to Images folder in your project. Change the names of the images to 1.jpg, 2.jpg etc. Step 4 : Right click on the Project Name in Solution Explorer in Visual Studio and add a new HTML Page. It should automatically add HTMLPage1.htm. Step 5 : Copy and paste the following HTML and JavaScript code in HTMLPage1.htm page. [img id="image" src="/Images/1.jpg" style="width: 150px; height: 150px" /] [br /] [input type="button" value="Start Slide Show" onclick="startImageSlideShow()" /] [input type="button" value="Stop Slide Show" onclick="stopImageSlideShow()" /] [script type="text/javascript"] var intervalId; function startImageSlideShow() { intervalId = setInterval(setImage, 500); } function stopImageSlideShow() { clearInterval(intervalId); } function setImage() { var imageSrc = document.getElementById("image").getAttribute("src"); var currentImageNumber = imageSrc.substring(imageSrc.lastIndexOf("/") + 1, imageSrc.lastIndexOf("/") + 2); if (currentImageNumber == 8) { currentImageNumber = 0; } document.getElementById("image").setAttribute("src", "/Images/" + (Number(currentImageNumber) + 1) + ".jpg"); } [/script] Finally run the application and test it.

Events in JavaScript
 
17:08
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

REACT JS TUTORIAL #5 - Javascript Events & Data Changes in React
 
07:27
Let's wrap up beginner React.js lessons with handling JS events and data changes in React.js. If you build a Reactjs app correctly, each component is able to be very "dumb"..it will only be aware of a few pieces of the application and can be reused in multiple places. If a component is only aware of the data it needs and the event(s) it needs to fire when things change, it can be extremely decoupled from the rest of the application and less prone to break as the React JS application changes over time.

Assigning event handlers in JavaScript using DOM object property
 
10:20
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/assigning-event-handlers-in-javascript.html In JavaScript there are several ways to associate an event handler to the event. In Part 36, we discussed, associating event handler methods to events using the attributes of HTML tags. In this video we will discuss using DOM object property to assign event handlers to events. First let us understand, what is DOM DOM stands for Document Object Model. When a browser loads a web page, the browser creates a Document Object Model of that page. The HTML DOM is created as a tree of Objects. Example : [html] [head] [title]My Page Title[/title] [/head] [body] [script type="text/javascript"] [/script] [div] [h1]This is browser DOM[/h1] [/div] [/body] [/html] JavaScript can be used to access and modify these DOM objects and their properties. For example, you can add, modify and remove HTML elements and their attributes. Along the same lines, you can use DOM object properties to assign event handlers to events. We will discuss the DOM object in detail in a later video session. We will continue with the same examples that we worked with in Part 36. Notice that in this case, we are assigning event handlers using the DOM object properties (onmouseover & onmouseout) instead of using the attributes of the HTML tag. We are using this keyword to reference the current HTML element. In this example "this" references the button control. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onmouseover = changeColorOnMouseOver; document.getElementById("btn").onmouseout = changeColorOnMouseOut; function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] The following example is same as the above. In this case we are assigning an anonymous function to onmouseover & onmouseout properties. [input type="button" value="Click me" id="btn" /] [script type="text/javascript"] document.getElementById("btn").onmouseover = function () { this.style.background = 'red'; this.style.color = 'yellow'; } document.getElementById("btn").onmouseout = function () { this.style.background = 'black'; this.style.color = 'white'; } [/script] If an event handler is assigned using both, i.e an HTML attribute and DOM object property, the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute. Here is an example. [input type="button" value="Click me" id="btn" onclick="clickHandler1()"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler set using HTML attribute"); } function clickHandler2() { alert("Handler set using DOM object property"); } [/script] Using this approach you can only assign one event handler method to a given event. The handler that is assigned last wins. In the following example, Handler2() is assigned after Handler1. So Handler2() owerites Handler1(). [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler1; document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script]

8 Inline CSS style  is nothing but a element Attribute
 
04:54
This was yet another Aha moment .For centuries together ,i could just not figure my head about understanding the style definitions written internally .This again is not good practise and it's always better writing the style sheets and Javascript in seperate folders for the same .However ,it serves well to know how they are written lest you need to analyse a code where style's have been written internally .Like discussed in teh video ,the common attribute key here stays as style and then the attribute value like any other attribute value is within quotes where we basically define the CSS properties

addeventlistener and removeeventlistener in JavaScript
 
11:51
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/01/addeventlistener-and.html In this video we will discuss assigning event handlers in JavaScript using the following special methods addEventListener removeEventListener attachEvent detachEvent Internet Explorer 9 (and later versions) & all the other modern browsers support addEventListener() and removeEventListener() methods. Sytnax for assigning event handler using addEventListener() method element.addEventListener(event, handler, phase) Sytnax for removing event handler using removeEventListener() method element.removeEventListener(event, handler, phase) Please note : The third parameter phase is usually set to false as it is not used. Example : In this example, we are passing values for all the 3 parameters including phase. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.addEventListener("mouseover", changeColorOnMouseOver, false); btn.addEventListener("mouseout", changeColorOnMouseOut, false); function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] Since the third parameter "phase" is optional you can omit it if you wish. btn.addEventListener("mouseover", changeColorOnMouseOver); btn.addEventListener("mouseout", changeColorOnMouseOut); Example : This example demonstrates removing event handlers. [input type="button" value="Click me" id="btn"/] [input type="button" value="Remove Event Handlers" onclick="removeEventHandlers()" /] [script type="text/javascript"] btn.addEventListener("mouseover", changeColorOnMouseOver); btn.addEventListener("mouseout", changeColorOnMouseOut); function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } function removeEventHandlers() { btn.removeEventListener("mouseover", changeColorOnMouseOver); btn.removeEventListener("mouseout", changeColorOnMouseOut); } [/script] Using this approach you can assign more than one event handler method to a given event. The order in which handler methods are executed is not defined. In this example, 2 event handler methods (clickHandler1 & clickHandler3) are assigned to click event of the button control. When you click the button both the handler methods are executed. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.addEventListener("click", clickHandler1); btn.addEventListener("click", clickHandler2); function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script] attachEvent() and detachEvent() methods only work in Internet Explorer 8 and earlier versions. Sytnax for assigning event handler using attachEvent() method element.attachEvent( "on"+event, handler) Sytnax for removing event handler using detachEvent() method element.detachEvent( "on"+event, handler) Example : This example will only work in Internet Explorer 8 and earlier versions. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] btn.attachEvent("onclick", clickEventHandler); function clickEventHandler() { alert("Click Handler"); } [/script] Cross browser solution : For the above example to work in all browsers, modify the script as shown below. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] if (btn.addEventListener) { btn.addEventListener("click", clickEventHandler); } else { btn.attachEvent("onclick", clickEventHandler); } function clickEventHandler() { alert("Click Handler"); } [/script]
