Hon*_*Vit 11 html javascript jquery jquery-select2
我用的是Select2 4.0.6,我有一个如下的bug:
allowClear在select上使用时给出"未捕获的TypeError:无法读取未定义的属性'id'".
我该如何修复这个错误？

如果您将debug属性设置为true您将看到一条警告消息.
该
allowClear选项应与placeholder选项结合使用 .

<script>
$("#myoption").select2({
allowClear: true,
width: '300px',
height: '34px',
debug: true
//data: data
});
</script>因此,您必须将占位符定义为默认值.
