Non-flush asynchronous transmission of Ajax JSON data for jquery Ajax instances

In the background of their own CMS, want to be on the same page with a pop-up mask layer of the way to modify member information

Getting userid is a big problem.

Last colleague's advice with $.ajax

The code is as follows

Copy Code

$ (' p.editinfo>a '). Bind (' click ', function () { $ (' #edit_uid '). Val ($ (this). attr ("UID")); Alert ($ (this). attr ("UID")); var uid= $ (this). attr ("UID"); alert (vote_content); $.ajax ({ Type: ' Get ', DataType: ' JSON ', URL: ' user_edit.php ', Data: ' uid= ' + uid, Success:function (JSON) { $ (' #username '). Val (Json.username); Assign a value to a corresponding JOSN value $ (' #mid_1 '). Val (Json.mid); $ (' #new_password '). Val (Json.password); $ (' #uid_edit '). Val (Json.uid); }, Error:function () {} }); }); });

The user_edit.php used to receive is the normal PHP SQL statement
Use the Json_encode function (refer to Php-json_encode)

The code is as follows	Copy Code
$uid = $_get[' uid ']; $query _admin_1 = $db->find ("table where uid= ' $uid ')"; $row _admin_1 = $db->fetch_array ($query _admin_1); $userinfo = Json_encode ($row _admin_1); Echo $userinfo;

The resulting $userinfo for JSON data storage format

A standard HTML form that receives JSON data

code is as follows	copy code
<div class= "txt-fld"                <label for= "" > User name </label>                <input id= "username" class= "good_input" name= "username" type= "text"               </div>               <div class= "txt-fld"              <label for= "" > User password/label>             <input id= "New_password" name= "new_password" type= "password"    />       </div>

Note that the Ajax operating part is not quite the same as it is, only in datatype: ' JSON ', and then we access the content in Json.mid this form, in fact, like the array $a[' a ', where JSON is a returned array, Mid is the ID we returned.
