jquery - 禁用更改 jquery 上的链接

Question

我想做的是禁用该链接。如果下拉选择值更改，如何禁用链接？

如果我选择在下拉列表中添加，则应禁用编辑和删除链接。帮忙？

<select id="">
<option value="add" selected="selected">Add</option>
<option value="edit">Edit</option>
<option value="delete">Delete</option>
</select>

  <a class="button add" style="cursor:pointer;"><span><b>Add Purchase Request</b></span></a>
  <a class="button edit" style="cursor:pointer;"><span><b>Edit Purchase Request</b></span></a>
  <a class="button remove" style="cursor:pointer;" name="remove"><span><b>Remove Purchase Request</b></span></a> 

Answer 1

试试这个，

$('select').change(function () {
    var va = $(this).val();
    if(va=='add'){
      $('.remove').attr('disabled', 'disabled');
    }
    else{
        $('.remove').removeAttr('disabled');
    }
});
