我是靠谱客的博主美满大叔，最近开发中收集的这篇文章主要介绍javascript 全角转换实现代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

下面我们来看下这个例子吧！

复制代码代码如下:

<html> 
    <head> 
        <title>jqueryDemo:quanjiaoNum</title> 
        <script src="jquery.js" src="jquery.js" type="text/javascript"></script> 
        <script type="text/javascript"><!-- 
            function changeNum(){ 
                var qjNum=$("input[@name=qjNum]").val(); 
                var toAscii=qjNum.charCodeAt(); 
                if(toAscii > 65295 && toAscii < 65306 && qjNum.length == 11) 
                { 
                    var toBack = 0; 
                    var temp = 0; 
                    var unite = ""; 
                    for(var i=0;i < qjNum.length;i++) 
                    { 
                        toAscii=qjNum.charCodeAt(i); 
                        toBack =toAscii-65248; 
                        temp = String.fromCharCode(toBack); 
                        unite = unite + temp ; 
                    } 
                    alert(unite); 
                    return true; 
                } 
                if(toAscii > 47 && toAscii < 58 && qjNum.length == 11) 
                { 
                    alert(qjNum); 
                    return true; 
                } 
                else{ 
                    alert("请输入正确的手机号码"); 
                    document.myform.qjNum.value=""; 
                    return false; 
                } 
            } 

// --></script> 
    </head> 
    <form name="myform" action=""> 
        中文数字转换成阿拉伯数字：<input type="text" id="qjNum" name="qjNum"/><input type="button" value="提 交" onclick="changeNum()"/> 
    </form> 
</html>
