我有这些数字
10999、8094和456
如果需要的话，我想做的就是在正确的位置添加一个逗号，这样看起来就像这样
10,999 and 8,094 and 456
这些都在一个p标签内，比如<p class="points">10999</p>等等.
这事办得到吗？
I've attempted it here with the help of other posts http://jsfiddle.net/pdWTU/1/ but can't seem to get it to work
谢谢

UPDATE
Messed around a bit and managed to figure it out here http://jsfiddle.net/W5jwY/1/
Going to look at the new Globalization plugin for a better way of doing it
谢谢

适用于所有浏览器，这就是你所需要的.
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
return val;
}
Wrote this to be compact, and to the point, thanks to regex. This is straight JS, but you can use it in your jQuery like so:
$('#elementID').html(commaSeparateNumber(1234567890));
或
$('#inputID').val(commaSeparateNumber(1234567890));
However, if you require something cleaner, with flexibility. The below code will fix decimals c或rectly, remove leading zeros, and can be used limitlessly. Thanks to @baacke in the comments.
function commaSeparateNumber(val){
val = val.toString().replace(/,/g, ''); //remove existing commas first
var valRZ = val.replace(/^0+/, ''); //remove leading zeros, optional
var valSplit = valRZ.split('.'); //then separate decimals
while (/(\d+)(\d{3})/.test(valSplit[0].toString())){
valSplit[0] = valSplit[0].toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
}
if(valSplit.length == 2){ //if there were decimals
val = valSplit[0] + "." + valSplit[1]; //add decimals back
}else{
val = valSplit[0]; }
return val;
}
And in your jQuery, use like so:
$('.your-element').each(function(){
$(this).html(commaSeparateNumber($(this).html()));
});
Here's the jsFiddle.
