How to get a response from a javascript post request
提问by Ostap Hnatyuk
So I'm using this post request I found on here, but I'm wondering how I receive a response using this...
所以我正在使用我在这里找到的这个帖子请求，但我想知道我如何使用这个收到回复......
function post_to_url(path, params, method) {
method = method || "post";
var form = document.createElement("form");
form.setAttribute("method", method);
form.setAttribute("action", path);
for(var key in params) {
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", key);
hiddenField.setAttribute("value", params[key]);
form.appendChild(hiddenField);
}
}ody.appendChild(form);
form.submit();
}
Thanks in advance.
提前致谢。

This code configures a form and submits it. You don't get any response to javascript, because the page reloads.
此代码配置一个表单并提交它。您没有收到任何对 javascript 的响应，因为页面会重新加载。
Try using jQuery: http://api.jquery.com/jQuery.post/
尝试使用 jQuery：http: //api.jquery.com/jQuery.post/
Or plain javascript AJAX: https://developer.mozilla.org/en/docs/AJAXif you want to write the whole thing yourself
或者普通的 javascript AJAX：https: //developer.mozilla.org/en/docs/AJAX如果你想自己写整件事
