推荐答案

您好，

基本上您可以为此使用Javascript / Jquery。您应该为每个文本框分配一个特定的类，例如amount，amountlbl。有数字的标签。

数字应该是这样的：-12345到12,345而不是1,23,45表示3的倍数。但你可以修改正则表达式/函数符合你的要求[CommaSepratedValues]。我已经厌倦了这个代码用于文本框或标签中的单个数字。我已经将CSS类数量分配给文本框并标记为amountlbl。





这是使用正则表达式的Java脚本代码

Hello,
Basically You Can Use Javascript/Jquery for this for this.you should assign a specific class such as amount , amountlbl to each textbox & label having number.
The Number should be like this :-12345 to 12,345 not 1,23,45 means in multiple of 3's. But you can modify the regular expression/functions to your requirements[CommaSepratedValues].I have tired this code for single number in textbox or label.I have assisgned a CSS class amount to textbox and label as amountlbl.


Here is the Java Script Code Using Regular expression

function CommaSepratedValue(nStr)
 {    try{
    if(nStr!=undefined || nStr !=null){
     nStr = nStr.replace(/,/g,'');
     nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;//For 2 numbers replace d{3} to d{2}
    while (rgx.test(x1))
    x1 = x1.replace(rgx, '

1' + ' ， + '

1' + ',' + '

2' ）;
return x1 + x2;
}
}
catch （呃）{
return nStr;
}

}

2'); return x1 + x2; } } catch(er){ return nStr; } }

现在给head标签中对jquery库的引用

最后写一下

Now give the reference to jquery library in head tag
In the end write
