Unable to get index from jQuery UI slider range
- by Phil.Wheeler
I'm having a hell of a time trying to get (what I thought was) a simple index from a collection of multiple sliders. The HTML is as follows:
<div id="left-values" class="line">
<span id="l1" style="padding: 0 1.8em;">0</span>
<span id="l2" style="padding: 0 1.8em;">0</span>
<span id="l3" style="padding: 0 1.8em;">0</span>
<span id="l4" style="padding: 0 1.8em;">0</span>
<span id="l5" style="padding: 0 1.8em;">0</span>
<span id="l6" style="padding: 0 1.8em;">0</span>
<span id="l7" style="padding: 0 1.8em;">0</span>
<span id="l8" style="padding: 0 1.8em;">0</span>
</div>
And the jQuery code is:
// setup audiometry sliders
$("#eq > span").each(function (e) {
// read initial values from markup and remove that
var value = parseInt($(this).text());
// var index = $(this).index; <- this didn't work.
$(this).empty();
$(this).slider({
value: value,
slide: function (event, ui) {
//console.log($(this).attr('id')); <- neither did this.
//console.log(index);
$('#left-values span:first').text(ui.value);
}
})
});
The problem is that jQuery UI - when creating a slider - replaces the existing HTML with its own markup. This includes any ID values and, for whatever reason, I can't get the index for a given slider to surface either. So I'm running out of ideas.
