The odd data in the page table is uploaded to the background through AJAX. why cannot the Chinese value be obtained? Why?

The page form data is uploaded to the background through AJAX, and the Chinese character cannot be taken? Why? JScriptcodevaruserindex = WebClient. store [0]. userIndex; varname =$ (& quot; name-input & quot ;). value; the page form data is uploaded to the background through AJAX, and the Chinese character cannot obtain the value? Why?

JScript code

           var userindex = WebClient.Store[0].UserIndex;      var name = $("name-input").value;        var phone = $("phone-input").value;        var babyname = $("babyname-input").value;        var password = $("password-input").value;                     var url = "php/login.phpaction=Modify&UserIndex="+userindex+"&Name="+name+"&Phone="+phone+"&BabyName="+babyname+"&Password="+password+"&random="+Math.random();

PHP code

      $name = "";    if(array_key_exists('Name',$_GET))    {        $name = trim($_GET['Name']);    }

Here, $ name can be displayed normally if the page data is in English, but cannot be displayed in Chinese. What's going on?

------ Solution --------------------
Encode the data with the encodeURIComponent () function before passing it to php.
------ Solution --------------------
The encoded value of ajax is utf-8. if your Chinese character is gb, it will be converted to UTF-8.
