问题描述
我想设置之前选择的选项以在页面加载时显示。我尝试了下面的代码:
I want to set a option that was selected previously to be displayed on page load. I tried it with the following code:
$("#gate").val('Gateway 2');with
with
<select id="gate"> <option value='null'>- choose -</option> <option value='Gateway 1'>Gateway 1</option> <option value='Gateway 2'>Gateway 2</option> </select>但这不起作用。任何想法?
But this does not work. Any ideas?
推荐答案这绝对应该有效。 下面是演示。确保已将代码放入 $(document).ready 中:
This definitely should work. Here's a demo. Make sure you have placed your code into a $(document).ready:
$(function() { $("#gate").val('Gateway 2'); });更多推荐
