Set attribute disabled to options NOT containing a certain string
- by kuswantin
I know this should be easier if I could only use optgroups. But I am trying to avoid hacking core of my CMS, so jQuery should come to rescue again, hopefully.
I have a select with options in a hierarchy sometimes, and I want to put attributes disabled to any of options containing text NOT starting with a dash.
I want to code like:
Set disabled attributes to selectors with options text NOT starting with a dash ("-").
<select id="options">
<option value="" selected="selected">- Please choose -</option>
<option value="1">Parent1</option>
<option value="2">-child1</option>
<option value="3">-child2</option>
<option value="4">-child3</option>
<option value="5">-child4</option>
<option value="6">Parent2</option>
<option value="7">-child5</option>
<option value="8">-child6</option>
<option value="9">-child7</option>
<option value="10">-child8</option>
</select>
The closest solution is here http://stackoverflow.com/questions/2012299/contain-start-by,
$.extend($.expr[':'], {
startsWith: function(elem,match) {
return (elem.textContent || elem.innerText || "").indexOf(match[3]) == 0;
}
});
But I can't seem to do it right this far.
Any help would be very much appreciated. Thank you very much.
