Question

I have a div which has some text content( eg: My Name ) and the div is in RED background colour

Answer 1

Or you could do the math and do the color change. http://jsfiddle.net/rustyDroid/WRExt/2/

> $("#btn").click(function(){
>     $('#bar').animate({ width: '300px' }, 
>     {
>         duration:10000,
>         easing:'linear',
>         step:function(a,b){
>             var pc = Math.ceil(b.now*255/b.end);
>             var blue = pc.toString(16);
>             var red = (255-pc).toString(16);
>             var rgb=red+"00"+blue;
>             $('#bar').css({
>                 backgroundColor:'#'+rgb
>             });            
>         }
>     })
>      });

try below code

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script>


     $(document).ready(function(){

        $("#button").click(function(){ 
            $('#myDivId').css("background-color","BLUE");
            $( "#effect" ).animate({
            backgroundColor: "yellow", }, 1000 );
      });
    });

</script>


<div id="myDivId" style="width:120;height:130;background-color:RED;text-align: center;">Text Area</div>

<input type="button" id="button" class="" name="click" value="click" >

And Let me know it's working or not...waiting for your reply .......

Furthemore of the previus coments (change background-color for backgroundColor) you also need the plugin Jquery Colors, I made a test and without it don't work.

Put this on the head:

  <script src="http://code.jquery.com/color/jquery.color.plus-names-2.1.0.min.js"></script>

I thought your looking for a "Progress Bar Animation"? try this: i believe its what your looking for - the progress bar's horizontal loading motion in a jsfiddle here:

http://jsfiddle.net/c78vF/6/

with a few more elements you are able to simulate that easily using the same tech everyone else is using here... jquery ui etc

html:

<button>Button</button>
<div id='myDivId'>
    <div class="progress"></div>
    <div class="content">
        DIV
    </div>
</div>

css:

#myDivId{
    background:red; 
    color:white; 
    padding:10px; 
    overflow:hidden; 
    position:relative;
}

.content{
    z-index:9;
    position:relative;
}
.progress{
    z-index;1;
    width:0px;
    height:100%;
    position:absolute;
    background:blue;
    left:0px;
    top:0px;
}

js:

$("button").click(function(){ 
      $('.progress').animate({ width: '100%' }, 10000);
});

Answer 5

Any particular reason you want to do this in jQuery as opposed to css3?

Bootstrap has a pretty nifty way of achieving this -> http://getbootstrap.com/components/#progress-animated

The .progress-bar class has a css3 transition set on the width property, so as you move between 0% & 100%, any updates to the width are smoothly animated. It also uses a css3 animation to animate the background gradient (striped pattern).

This can be done using span changing its width over the time. Here is the working fiddle. The code is displayed below. Only the mandatory styles are displayed here.

HTML

<div class="red-button">
    <span class="bg-fix"></span>  //this is the only additional line you need to add
    <p>Progress Button</p>
</div>
<button class="click-me">Click Me</button>

CSS

.red-button {
    position: relative;
    background: red;
}
span.bg-fix {
    display: block;
    height: 100%;
    width: 0;
    position: absolute;
    top: 0;
    left: 0;
    background: blue;
    transition: width 10s ease-in-out;
}
p {
    position: relative;
    z-index: 1
    width: 100%;
    text-align: center;
    margin: 0;
    padding: 0;
}

jQuery

$("div.red-button").click(function () {
  $('span.bg-fix').css("width", "100%");
});
