<input type='submit' value='Submit' onclick='this.form.action="somethingelse";' />
Or you can modify it from outside the form, with javascript the normal way:
或者您可以从表单外部修改它，使用 javascript 正常方式：
document.getElementById('form_id').action = 'somethingelse';

There's a simple way to do this if you only need to support modern browsers: on your submit button, add a formaction="/alternate/submit/url"attribute like so:
如果您只需要支持现代浏览器，有一种简单的方法可以做到这一点：在您的提交按钮上，添加如下formaction="/alternate/submit/url"属性：
<form>
[fields]
<input type="submit" value="Submit to a" formaction="/submit/a">
<input type="submit" value="submit to b" formaction="/submit/b">
</form>
It also works on <button>tags.
它也适用于<button>标签。
The gotcha is that old versions of IE (<10) and the Android Browser (<4.0) do not support it. So, if you need to support older browsers, then the existing JS answers will probably work better for you.
问题是旧版本的 IE (<10) 和 Android 浏览器 (<4.0) 不支持它。因此，如果您需要支持较旧的浏览器，那么现有的 JS 答案可能更适合您。

You can also set onSubmitattribute's value in form tag. You can set its value using Javascript.
您还可以onSubmit在表单标签中设置属性的值。您可以使用 Javascript 设置其值。
Something like this:
像这样的东西：
<form id="whatever" name="whatever" onSubmit="return xyz();">
Here is your entire form
<input type="submit">
</form>;
<script type=text/javascript>
function xyz() {
document.getElementById('whatever').action = 'whatever you want'
}
</script>
Remember that onSubmithas higher priority than action attribute. So whenever you specify onSubmitvalue, that operation will be performed first and then the form will move to action.
请记住，onSubmit它比 action 属性具有更高的优先级。因此，每当您指定onSubmit值时，将首先执行该操作，然后表单将移动到操作。

You can do that on javascript side .
你可以在 javascript 端做到这一点。
<input type="submit" value="Send It!" onClick="return ActionDeterminator();">
When clicked, the JavaScript function ActionDeterminator() determines the alternate action URL. Example code.
单击时，JavaScript 函数 ActionDeterminator() 确定备用操作 URL。示例代码。
function ActionDeterminator() {
if(document.myform.reason[0].checked == true) {
document.myform.action = 'http://google.com';
}
if(document.myform.reason[1].checked == true) {
document.myform.action = 'http://microsoft.com';
document.myform.method = 'get';
}
if(document.myform.reason[2].checked == true) {
document.myform.action = 'http://yahoo.com';
}
return true;
}
