Contains number of times the ajax call has been made.
Each time an ajax request is made, data-counter is incremented. Combined
with data-limit, you can control the maximum number of times your ajax call
can be made. At any time, you can use $('selector').data('counter') to get
the counter's current value.
This form looks like this:
<input
id="test"
type="button"
value="Do an ajax call"
class="btn domajax click"
data-endpoint="counter-value-handler.php"
data-output="#output"
/>
<br/><br/>
<input
type="button"
id="get"
class="btn"
value="Get counter value"
/>
<br/><br/>
<input
type="button"
id="reset"
class="btn"
value="Reset counter value"
/>
<br/><br/>
<div id="output"></div>
<script type="text/javascript">
$('#get').click(function() {
alert($('#test').data('counter'));
});
$('#reset').click(function() {
$('#test').data('counter', 0);
});
</script>
