[英]How to catch GET request url from form submit
I have a quite complicated HTML form.我有一个相当复杂的 HTML 表单。 This form sends a GET request to the server.
此表单向服务器发送 GET 请求。 On submit event I would like to catch this GET URL and send it like an ajax request.
在提交事件时,我想捕获这个 GET URL 并像 ajax 请求一样发送它。 But don't know how to get this submit URL.
但不知道如何获得这个提交网址。
I would like to have it in pure JavaScript and not with jQuery.我想使用纯 JavaScript 而不是 jQuery。 I tried to do it via:
我试图通过以下方式做到这一点:
addEventlistener('beforeunload', function(e) {
e.preventDefault();
var getUrl = location.href;
});
The problem with this code is that it is not triggered by form submit, and I don't know if location.href
is a good idea.这段代码的问题是不是表单提交触发的,不知道
location.href
是不是个好主意。
How could it be done?怎么可能呢?
Use an event listener on the form's submit
event.在表单的
submit
事件上使用事件侦听器。
document.querySelector("#yourform").addEventListener('submit', function(e) {
e.preventDefault(); // block the default GET request
let url = this.action;
// rest of code for sending AJAX request to url
});
