[英]Change selected item from select2 with ajax
I want to use jquery to select the value of the desired item from select2.When I manually write the following code, it works correctly.我想使用 jquery 到 select select2 中所需项目的值。当我手动编写以下代码时,它可以正常工作。
<!-- language: lang-html -->
<select class="form-control select2" id="voip">
<option value="101001001">A</option>
<option value="101001002">B</option>
<option value="101001003">C</option>
<option value="101001004">D</option>
</select>
$('#voip').val('101001003').trigger('change');
But when I receive the desired value with Ajax, it does not work.但是当我收到 Ajax 所需的值时,它不起作用。 Please guide me, thank you请指导我,谢谢
$.ajax({
url:"ajax_voip.php?internal=1",
method:"GET",
success:function(data)
{
$('#voip').val(data).trigger('change');
alert(data);//this ok return 101001003
}
})
it's possible your ajax call is returning a number and not a string... try:您的 ajax 调用可能返回数字而不是字符串...尝试:
$('#voip').val((""+data).trim()).trigger('change');
