Example of jquery getting URL parameters and transcoding, jqueryurl

Using jquery to obtain URL parameters and transcode them, I personally think it is good because sometimes garbled characters are not transcoded.
Jquery obtains URL parameters and transcodes them. First, it constructs a regular expression object containing the target parameters, matches the target parameters, and returns the parameter values.
Code:

<Script type = "text/javascript"> $ (document ). ready (function () {var pic_url = getUrlParam ("picture"); $ ("# childpic "). attr ("src", pic_url); var content = getUrlParam ("content "); $ ("# content" pai.html ("<B>" + content + "</B>") ;}); // www. jbxue. comfunction getUrlParam (name) {// construct a regular expression object with the target parameter var reg = new RegExp ("(^ | &) "+ name +" = ([^ &] *) (& | $) "); // match the target parameter var r = window. location. search. substr (1 ). match (reg); // ale Rt (r); // return the parameter value if (r! = Null) return decodeURI (r [2]); return null ;}</script>

Test url: http://xxxx.html? Picture = "XXXX" & content = "Hello! "

Determine the url parameter obtained by jquery and change the id value

Function parse_url (url) {if (url. lastIndexOf ('? ') = 0) {var str = url. substring (url. lastIndexOf ('? ') + 1, url. length); var arr = str. split ('&'); var parames = []; for (var I = 0; I <arr. length; I ++) {parames [arr [I]. split ('=') [0] = arr [I]. split ('=') [1];} return parames;} var type = parse_url (location. search); if (type) {if (type ['lang '] = 'Fr') {document. getElementById ('id '). innerHTML = 'good thanks '; document. getElementById ('id1 '). innerHTML = 'good thanks ';} the code should be placed behind the two elements id: 'id' and 'id1'

That is to say, when executing this code, make sure that the page elements are loaded.
