How JavaScript data is transmitted on different pages
This article introduces how JavaScript data is transmitted on different pages. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.
In web pages, we often encounter this situation, when we enter information on one page, we will jump to another page, and will pass the information we entered to another page, how to do it?
Today, let's do some practical work. For example, now there are two pages, and when we enter user information on one page, we jump to the other page and display, xx Welcome login interface.
Let's take a look at the design ideas:
The first login page with a submission form, which is submitted by action to the index.html page
For the second page, you can use the parameters of the first page to achieve the effect of transferring data between different pages.
The reason why the second page can use the data of the first page is that it uses the location.search parameter in URL.
On the second page, you need to extract this parameter.
The first step is to use substr to remove it.
The second step uses split ('=') to split keys and values
The first array is the key and the second array is the value.
The implementation code is:
User name: welcome to login! Var span = document.querySelector ('span'); / / get the span tag var myName = location.search.substr (1); / / get the parameter var arr = myName.split (' =') entered on the previous page; / / use the = sign division key and the value span [XSS _ clean] = arr [1] +''/ / to pass the data into span
The running effect is as follows:
