How to solve ajax request garbled characters (Chinese garbled characters) _ javascript tips-js tutorial

This article mainly introduces how to solve ajax request Garbled text (Chinese Garbled text). For more information about how to transmit Chinese Characters in ajax requests, see the problem encountered today.

The following code:

The Code is as follows:

Function UpdateFolderInfoByCustId (folderId, folderName, custId ){
$. Ajax ({
Type: "Post ",
ContentType: "application/x-www-form-urlencoded; charset = UTF-8 ",
Url: "http: // localhost/CRM/Ashx/HandKBSucessCustomer. ashx? Method = UpdateCustomerByCustId & folderId ="
+ FolderId + "& folderName =" + encodeURI (folderName) + "& custId =" + custId,
Success: function (msg ){
Alert (msg );
},
Error: function (error ){
Alert (error );
}
});
}

If the above Code only transmits "& foderName =" + folderName, Chinese characters will produce garbled characters. If it is converted twice through encodeURL, the Chinese character encoding will become similar

"% E6 % b5 % 8b % eb % af % 95" format. After being converted to this format, transcoding is performed when obtaining it, as shown below:

The Code is as follows:

Public void UpdateCustomerByCustId ()
{
Int folderId = Convert. ToInt32 (Request ["folderId"]);
String folderName = Request ["folderName"];
String folderName2 = Convert. ToString (System. Web. HttpUtility. UrlDecode (folderName ));
Int custId = Convert. ToInt32 (Request ["custId"]);
Bool res = false;
Try
{
Res = CustomerBusiness. UpdateCustomerByCustId (folderId, folderName2, custId );
}
Catch (Exception ex)
{
Throw;
}
Response. Write (res );
}
}
}

After this conversion, you can obtain the transmitted Chinese characters.
