更准确地说，我需要做一个
我在服务器端使用JSP
I'm trying to find a function in JavaScript that is called everytime when a <form> or <select> is created. Does anyone have a idea?
I want something like:
<body onload="jsFunction();">
More exactly, I need to make a <select> that will be included in many pages, and I want everytime this is loaded, to select one of it's values based on a request variable. So the function that will make the selection must called from this included script and must be included in this script.
I'm using JSP on the server side

这毫无意义。只需根据请求参数以编程方式设置整个
selected属性即可。这是一个示例：或者如果您将其放在集合中：
对于普通输入也是如此：
（
fn:escapeXml()是为了防止 XSS 攻击）This makes no sense. Just set the whole
selectedattribute programmatically based on the request parameter. Here's an example:or if you have it in a collection:
The same is true for normal inputs:
(the
fn:escapeXml()is there to prevent XSS attacks)您可以尝试在默认情况下要选择的选项中使用“selected”属性（如此处的建议）。如果您更喜欢 javascript，则需要使用 jquery 之类的工具来选择（或填充并选择）您的标签。
供参考：
You could try the "selected" attribute in the option you want to select by default (like suggested here). If you prefer javascript, you'll need to use something like jquery to select select (or populate and select) your tag.
