You cannot invoke JavaScript functions in standard HTML attributes other than onXXX .(您不能在onXXX以外的标准HTML属性中调用JavaScript函数。)

Just assign it during window onload.(只需在窗口加载期间分配它。) <script type="text/javascript"> window.onload = function() { document.myform.action = get_action(); } function get_action() { return form_action; } </script> <form name="myform"> ... </form> You see that I've given the form a name , so that it's easily accessible in document .(您看到我已经为表单指定了name ，因此可以在document轻松访问。) Alternatively, you can also do it during submit event:(或者，您也可以在submit活动期间执行此操作：) <script type="text/javascript"> function get_action(form) { form.action = form_action; } </script> <form onsubmit="get_action(this);"> ... </form>
