I have a Jqgrid which dinamically generates selects like this:
我有一个 Jqgrid，它动态生成这样的选择：
<select id="won" style="width: 65px;">
<option value="">-WON?</option>

The problem is that the select are created dynamically, then you need to use .on()
问题是select是动态创建的，那么你需要使用 .on()
try this:
尝试这个：
$(document).on('change','#won',function(){
alert("PROBANDO");
});

This should work, be sure you did not forget $(document).ready(function() {
这应该有效，确保你没有忘记 $(document).ready(function() {
$(document).ready(function() {
$('#won').change(function(){
alert( $(this).find("option:selected").attr('value') );
});
});
