JS implements the method of passing parameters to page a to page b

This article shares with you the specific method of passing parameters to page a to page b for your reference. The specific content is as follows

Method 1:LocalStorage component (localStorage can store 5M data locally) localStorage is a local permanent storage data and is the optimization of cookies.

Method 2:Use cookies to store data in the client's browser (maximum storage of 2M data)

Method 3:Use url to pass parameters (save the data to be passed as a storage variable and then pass it to url) as follows;

var app = {};
 = '123'
 = '1';

 = "?name="+app;

If the parameters are objects, you must first convert the characters (app) and then convert them into objects if they are obtained on page b.

Receive the parameters passed by the url

function GetRequest() {  
  var url = ; //Get the string after the "?" character in the url  var theRequest = new Object();  
  if (("?") != -1) {  
   var str = (1);  
   strs = ("&amp;");  
   for(var i = 0; i &lt; ; i ++) {  
     theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);  
   }  
  }  
  return theRequest;  
}  
((GetRequest().name).list)

Each browserThere are restrictions on the length of the URL:

1. The IE browser now limits the length of the URL to 2048 bytes (up to 2047 bytes for testing by yourself).

2. 360 Speed Browser limits the length of the URL to 2118 bytes.

3. Firefox (Browser) limits the length of the URL to 65536 bytes.

4. Safari(Browser) limits the length of the URL to 80,000 bytes.

5. Opera(Browser) limits the length of the URL to 190,000 bytes.

6. Google (chrome) limits the length of the URL to 8182 bytes.

Here, I have only tested IE browser and 360 Speed Browser, and other browsers come from information on the Internet.

Also, I would like to remind you that in the URL, a Chinese character has different sizes through different encoding methods.

The above is how js implements the method of passing parameters to another page. I hope it will be helpful for everyone to learn JavaScript programming.
