javascript - 如何通过我的自定义值设置HTML中的SELECT OPTION？(How to set SELECT OPTION in HTML by my custom value?)

Question

I have a select field with some options in it.

(我有一个选择字段，里面有一些选项。)

Now I need to select one of those options with jQuery.

(现在，我需要使用jQuery选择这些选项之一。)

But how can I do that when I only know the value of the option that must be selected?

(但是，当我只知道必须选择的选项的值时，该怎么办？)

I have the following HTML:

(我有以下HTML：)

 <div class="id_100"> <select> <option value="val1">Val 1</option> <option value="val2">Val 2</option> <option value="val3">Val 3</option> </select> </div> 

I tried to do this with a tag but this does not work.

(我尝试使用标签来执行此操作，但这不起作用。)

Please tell me about other ways.

(请告诉我其他方法。)

Thanks in advance

(提前致谢)
