/ / Please paste the code text below (do not replace the code with pictures)
$("- sharpmultiselect") .change (function () {
$("select :selected").each(function() {
str +=","+$(this).val();
});
//strformaction
});
the official http://api.jquery.com/val/ document contains the following description
When the first element in the collection is a select-multiple (i.e., a select element with the multiple attribute set), .val () returns an array containing the value of each selected option. As of jQuery 3.0, if no options are selected, it returns an empty array; prior to jQuery 3.0, it returns null.
so the following code can get the selected value
<select id="elem" multiple="multiple">
<option>...</option>
...
</select>
var values = $('-sharpelem').val();
