Solution to garbled ajax request (Chinese garbled code)_javascript skills

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(encodeURI(folderName)) "&custId=" custId,
success: function (msg) {
                                                            ;


If you just pass "&foderName=" folderName in the above code, the Chinese characters will be garbled. If converted twice through encodeURL, the Chinese character encoding will become similar to

The format of “test믕”. After converting to this format, transcode when retrieving, as shown below:

}
}



After this conversion, the transmitted Chinese characters can be obtained.
