js格式化金额的代码 js中文大写金额的代码

发布时间:2015-07-03   编辑:www.jquerycn.cn
本文介绍了js实现金额格式化的代码,用js实现中文大写金额,有需要的朋友参考学习下。

例子,js实现数字金额的格式化。
 

复制代码 代码示例:

<mce:script language="javascript">
<!--  
function formatNum(num,n) 
{//参数说明:num 要格式化的数字 n 保留小数位 
    num = String(num.toFixed(n)); 
    var re = /(-?/d+)(/d{3})/; 
    while(re.test(num)) num = num.replace(re,"$1,$2") 
    return num; 

alert(formatNum(1234005651.789,2));  
// --></mce:script>

    v = (v == Math.floor(v)) ? v + ".00" : ((v * 10 == Math.floor(v * 10)) ? v 
            + "0" : v); 
    v = String(v); 
    var ps = v.split('.'); 
    var whole = ps[0]; 
    var sub = ps[1] ? '.' + ps[1] : '.00';

    while (r.test(whole)) { 
        whole = whole.replace(r, '$1' + ',' + '$2'); 
    } 
    v = whole + sub; 
     
    return v; 

 
/*转为以万为单位*/ 
function rendererZhMoneyWan(v) { 
    if(isNaN(v)){
