我正在尝试在页面上的一个元素内增加一个数字.但是,我需要的数字包括千分之一个值的逗号. (例如45,000不是45000)
<script>
// Animate the element's value from x to y:
$({someValue: 40000}).animate({someValue: 45000},{
duration: 3000,easing:'swing',// can be anything
step: function() { // called on every step
// Update the element's text with rounded-up value:
$('#el').text(Math.round(this.someValue));
}
});
</script>
<div id="el"></div>
如何用逗号加一个数字？

随意更改更多的需要,你也可以看货币格式化,希望这将适合你的需要:)
码
// Animate the element's value from x to y:
var $el = $("#el"); //[make sure this is a unique variable name]
$({someValue: 40000}).animate({someValue: 45000},// can be anything
step: function() { // called on every step
// Update the element's text with rounded-up value:
$el.text(commaSeparateNumber(Math.round(this.someValue)));
}
});
function commaSeparateNumber(val){
while (/(\d+)(\d{3})/.test(val.toString())){
val = val.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g,"$1,");
}
return val;
}
**输出*
