最近項目中有一個業務是收銀員經過輸入用戶卡號,給用戶充值或者消費,可是爲了不誤操做(如卡號輸錯),因而編寫了一個遠程驗證的jQuery插件,javascript
當收銀員輸入卡號後,失去焦點,當即ajax請求服務器端,並返回信息,而後能夠經過在success回調函數自定義(html自定義)顯示內容。css
先上幾張演示效果圖:html
html 代碼調用方法:
<html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="jRemoteValidate.js"></script> <style type="text/css"> .container {width:600px;margin-top:20px;} </style> </head> <body> <div id="cardContainer" class="container"> <label for="mobile" style="float:left;">test:</label> <input type="text" id="mobile" /> </div> <body> </html>
javascript 代碼調用方法:
$('#mobile').jRemoteValidate({ url: 'json1.html', field: 'mobile', // send param mobile=$('#mobile').val() to server renderTo: '#cardContainer', //container loadImgURL: 'loading_small.gif', //loading image path success: successHandle }); // custom you want show's message format function successHandle(rs) { var html = ''; if(rs.state == 1) { html = '<p class="msg">name:<font color=#4682B4>'+rs.data.name+ '</font>,balance:$<font color=red>'+rs.data.balance+'</font></p>'; } if(rs.state == 2) html = '<p class="msg"><font color=red>card is not exists!</font></p>'; if(rs.state == 3) html = '<p class="msg"><font color=red>server error! </font></p>'; return html; }
代碼調用很是簡單,源碼託管在github上,須要的能夠下載。java
