each portion of image having (or with) different id - jquery

I have an image with id myimage. It has a width of 300px and height 100px. each 100px wide portion has a unique color, like below

------------------------
| red  | green | blue  |
------------------------

Is it possible to use each portion (having width & height 100px) with different id so that the image can be used as a button with 开发者_JS百科different functions to each portion??

Answer only if it is possible and comment for others.

thanks in advance...:)

Set your image as a background image and give the parent div position:relative property. Then use nested divs with position:absolute each 100px apart from one another.

<div id="wrap">
    <div class="first"></div>
    <div class="second"></div>
    <div class="third"></div>
</div>

#wrap{
    background:transparent url(...) no-repeat 0 0;
    width:300px;
    height:100px;
    position:relative;
}

.first, .second, .third{
    position:absolute;
    top:0;
    width:100px;
    height:100px;
}
.first{
    left:0;
}
.second{
    left:100px;
}
.third{
    left:200px;
}

Now using JQuery you can reference each part individually.

$('.first').click(function(){ // this is the first part
 alert('first clicked')
})
