Two page parameter JS

Scene:

Similar to popular reviews need to choose the location, and then connect to other pages, in other pages will also use this location and if previously selected location

Method One:

Use session

Sessionstorage is the session store, and the browser is off.

Localstorage is persistent storage and can be used to replace cookies with greater storage space.

Implementation method

Save: sessionstorage["Address"]= "Beijing";

Fetch: sessionstorage["Address"]

Localstorage implementation method is the same as Sessionstorage

Method Two: With the "How to obtain the url# number after the parameter"

Pass the parameters after the URL

b.html?teacher=xx&time=xxx

Back to the problem, first from a.html to b.html need a jump way, for example, in the a.html page you have a link:

<a href="b.html" id="toPageB">跳转到b页面</a>

The rest is good, get the parameters you need, then modify the page URL:

var dataFromLi=[$("#Teachername").text(),$("#Credit_hour").text()];$("#toPageB").attr("href","b.html?data="+dataFromLi);

The URL is then parsed on the b.html page to get the parameters.

How to get parameters based on URLs:

Window.location.search will return all address bars from "?" The starting string. Getting a parameter value can pass regular, here is a simple function to get the parameter:

function getURLParameter(name) {    return decodeURIComponent((new RegExp(‘[?|&]‘ + name + ‘=‘ + ‘([^&;]+?)(&|#|;|$)‘).exec(location.search)||[,""])[1].replace(/\+/g, ‘%20‘))||null;}

If you use jquery, you can do it in a simpler way:

$.url().param(‘data‘);
