Ajax Chinese garbled Solution final version-compatible IE and Ff__ajax

The core of Ajax technology is JavaScript, and JavaScript uses UTF-8 encoding, so when the page uses GBK or other encoding, without encoding conversion, there will be the problem of garbled Chinese. Here are the different test results and garbled solutions for the page using GBK and UTF-8 encoded under IE and FF, respectively, with Get and post methods

Pass Value method	Client-side encoding	Server-side encoding	Ie	Ff	Solution
Get	UTF-8	UTF-8	Garbled when receiving parameters passed by $_get	Normal	Client Url=encodeuri (URL)
Get	GBK	GBK	Normal	Garbled when receiving parameters passed by $_get	Client Url=encodeuri (URL) Server-side $str =iconv ("UTF-8", "GBK", $str)
POST	UTF-8	UTF-8	Garbled when receiving parameters passed by $_get	Normal	Client Url=encodeuri (URL)
POST	UTF-8	UTF-8	Normal to receive parameters passed by $_post	Normal to receive parameters passed by $_post	Recommended way to use
POST	GBK	GBK	Normal	Garbled when receiving parameters passed by $_get	Client Url=encodeuri (URL) Server-side $str =iconv ("UTF-8", "GBK", $str)
POST	GBK	GBK	Garbled when receiving parameters passed by $_post	Garbled when receiving parameters passed by $_post	Server-side $str =iconv ("UTF-8", "GBK", $str)

The following is the code for the test:

Client index.php

<?php header ("Content-type:text/html;charset=utf-8");?> <input type= "button" value= "Load" id= "Button1" >
		<div id= "Div1" >Loading</div> <script type= "Text/javascript" > Window.onload=function () {
			document.getElementById ("Button1"). Onclick=function () {var xmlHttp;
			var url= "t.php?id= ' Test ' &nu=" +math.random ();              Url=encodeuri (URL); Here is the key if (window).
			XMLHttpRequest) {xmlhttp=new XMLHttpRequest ();
			else {xmlhttp=new ActiveXObject ("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function () {if (xmlhttp.readystate==4&&xmlhttp.status==200) {document.ge
				Telementbyid ("Div1"). Innerhtml=xmlhttp.responsetext;
			} xmlhttp.open ("Get", url,true);
			Xmlhttp.send ();
			Xmlhttp.open ("POST", "t.php", true);
			Xmlhttp.open ("POST", url,true);
			Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");
			Xmlhttp.send ("id= ' Test ' &nu=" +math.random ());
Xmlhttp.send ();		}} </script> 

Server-Side t.php

<?php
	Header ("Content-type:text/html;charset=utf-8");
	echo "This is Test Chinese"; If this is directly to the client output Chinese, not through the $_get or $_post pass parameters
	//Only the client and server-side coding consistent, whether UTF-8 or GBK, will not appear garbled
	echo $_get[' id '].$_get[ ' Nu '];
	Echo iconv ("UTF-8", "GBK", $_get[' id '].$_get[' nu ']);
	echo $_post[' id '].$_post[' nu '];
	Echo iconv ("UTF-8", "GBK", $_post[' id '].$_post[' nu ']);
? >

Another problem may exist in IE:

The operation could not be completed due to an error c00ce56e

At this point, the header (' Content-type:text/html;charset=utf8 ') is changed to header (' Content-type:text/html;charset=utf-8 ') when the encoding is set.
