jQuery-数字格式问题 [英] jquery - number formatting issue

问题描述

这是我的代码:

<script src="js/jquery.js" type="text/javascript"></script>
<script src="js/jquery.field.js" type="text/javascript"></script>
<script src="js/jquery.calculation.js" type="text/javascript"></script>    
<script>    
   $(function() {
      $('input[name^=sum]').keyup(function() {
            var sum1 = parseFloat($('input[name=sum1]').val()) || 0;
            var sum2 = parseFloat($('input[name=sum2]').val()) || 0; 
            var sum3 = parseFloat($('input[name=sum3]').val()) || 0; 

            $('#c_card_amount').val(sum1*sum3/100);        
            $('#total_inc_charges').val((sum1*sum3/100)+sum1);
       });
   });
</script>

在输入字段中，我想以1,000.00格式显示数字.

In the input fields I would like to show the numbers in 1,000.00 format.

如何格式化这样的数字?现在，在计算之后，数字有时会像452.25600000001那样混乱.我也想避免这种情况.最好正确地控制数字.

How can I format the numbers like this? Right now after the calculation numbers sometimes gets messed up like 452.25600000001. I would like to avoid that as well. Would be nice to rule the numbers properly.

感谢您的帮助.

推荐答案

我建议您尝试 jQuery格式在此问题中提到:在javascript中格式化数字.

I would recommend you to try jQuery Format as mentioned in this question: Format numbers in javascript.

以下是jQuery格式的示例:

Below is an example of jQuery Format:

$.format.locale({
    number: {
        groupingSeparator: ',',
        decimalSeparator: '.'
    }
});
$.format.number(1000, '#,###.00');    // result: 1,000.00
$.format.number(452.25600000001, '#,###.00');    // result: 452.26
