$(obj).attr('disabled', true);

Try this
尝试这个
$(obj).attr("disabled","disable")
note value of attribute "disabled" is "disable" not "disabl*ed*"
注意属性“禁用”的值是“禁用”而不是“禁用* ed*”

Here's an example of disabling a button after it has been clicked. Notice that you pass the "this" object to the click event handler :
这是在单击后禁用按钮的示例。请注意，您将“this”对象传递给 click 事件处理程序：
<input type="button" value="Submit" onclick="disable(this)"/>
And the javascript:
和 javascript：
<script>
function disable(control){
control.disabled = true;
}
</script>
