如何使用jQuery使用逗号使用动画来增加数字？

Question

我正在尝试在页面上的元素内增加一个数字.但是我需要用数字来包含第千个值的逗号.(例如45,000而不是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>

您可以随意更改它以满足您的需求,您还可以查看货币格式化程序,希望这符合您的需求 :)

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}, {
      duration: 3000,
      easing:'swing', // 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*

您还应该添加一个完整的函数:

step:function(){
    //..
},
complete:function(){
    $el.text(commaSeparateNumber(Math.round(this.someValue)));
}
