URL 更改事件 - JavaScript

Question

I have a setTimeout that records the URL in a variable called newURL .

function checkURL() {
    var newURL = window.location;
} setInterval(checkURL, 1000);

What I would like to happen, is that a certain function must be executed, when the URL changes. Could someone help me here please?

Answer 1

Not sure why the page wouldn't reload before you could catch the change in the url. You can also take a look a window.onunload

var checkURL = (function () {
    var oldURL = location.href;
    return function (fn) {
        var newURL = location.href;
        if (fn && oldURL !== newURL) {
            fn(oldURL, newURL);
        }
        oldURL = newURL;
    };
}());

Answer 2

From what i understand, when the url changes will be a new execution of the JS scripts in that page. The " window.location" will return the current URL, but JavaScript not record /register data in script, or variablle from a page to another.

Answer 3

Use a global variable to store old url. Than you can check if the url was changed and execute some function.
