This article mainly introduces JS how to get the page URL, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

A JS simply gets the source address of the page.

Jump was previously used when writing ASM. After entering page B from page A, after various operations, the submission was successfully redirected to the successful prompt page, and then transferred to page A from the prompt page. In fact, it is not difficult to achieve, the easiest way is to pass parameters, available parameters must be modified a large number of pages, because this A page is not only one page, but can enter the B page from multiple entrances, and then jump back to the original entry after success. In order to quickly develop and modify a small amount of code, I thought of using JS to get the access source on the B page to achieve the customer's requirements.

The following is a Demo of the JS code for page B:

XML/HTML code

Get the page source functiongetFrom () {varurl=document.referrer; if (url== ") {url=" directly enter the URL ";} varlocalUrl=_window.location.href.toString (); window.alert (" Source: "+ url+" this page address: "+ localUrl);} Click here to display the page source address

Use notepad to put the above code Copy in and save it as getReferrer.htm, and then build a html page to link to that page.

Note: if the A page is redirected in the way of "location.href", the value obtained is empty, because this jump method is equivalent to entering the URL directly in the address bar, and it is not available to open the page directly from the search folder.
