How to cause a form to be submitted automatically on page load in JavaScript?
提问by Toney
This may have an obvious answer, but I am very new to js so I have no idea how to do this. I would like a form on a page to be submitted automatically when that page is loaded without requiring any user action like pressing a button. How to do this?
这可能有一个明显的答案，但我对 js 很陌生，所以我不知道如何做到这一点。我希望页面上的表单在加载该页面时自动提交，而无需任何用户操作，例如按下按钮。这该怎么做？

Like this:
像这样：
window.onload = function(){
document.formName.submit();
};

I'd go with what sAc suggests, but I'd use an event listener rather than just writing to window.onload:
我会采用 sAc 的建议，但我会使用事件侦听器，而不仅仅是写入 window.onload：
function submit_form() { document.formName.submit(); }
if(window.attachEvent){
window.attachEvent("onload", submit_form);
}else{
window.addEventListener("load", submit_form, false);
}
