How to add a certain value to anchor tag?

If you want to add a random attribute for a value, you can use data attributes:

<a href="#" data-value="1">Text</a>

<script type="text/javascript">
$("a").click(function(){
    i=$(this).data("value");
    $('#square').animate({'left': i * 360});
});
</script>

If you are using HTML5 you can use the data- technique.

<a id="target" href="http://foo.bar" data-custom-value="1">Text</a>

$("#target").click(function() {
    var value = $(this).data("custom-value");
    // do other stuff.
});

EDIT

Usage of .data instead of .attr is more appropriate

you can use custom data attributes see this .

<a href="#" data-json="{ 'myValue':'1'}">Click</a> //you can even pass multiple values there.

then access it using data() function.

Or instead of using json you can put it as an attribute :

<a href="link"  myvalue="1"">

then get it using :

$("#link").data("myvalue")
