键入时在输入字段中为数字添加逗号

This does it incorrectly: Can jQuery add commas while user typing numbers?

这样做不正确:jQuery可以在用户输入数字时添加逗号吗?

  $('input.number').keypress(function(event){
      if(event.which >= 37 && event.which <= 40){
          event.preventDefault();
      }
      var $this = $(this);
      var num = $this.val().replace(/,/g, '');
      $this.val(num.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,"));
  });

I need "1000000" to be "1,000,000" or better with spaces "1 000 000".

我需要“1000000”为“1,000,000”或更好,空间为“1 000 000”。

Please help. Thanks.

if you wanted to have something like "1 000 000", you can change the code to something like this.

如果你想拥有类似“1 000 000”的东西,你可以将代码改为这样的东西。

  var num = $this.val().replace(/(\s)/g, '');
  $this.val(num.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1 "));

Hope this helps

You can use Digital Bush's Masked Input Plugin for Jquery. It has many options for customisation including spaces, eg:

你可以使用Digital Bush的Masked Input Plugin for Jquery。它有许多自定义选项,包括空格,例如:

$("#myInputText").mask("9 999 999",{placeholder:" "})

It seems to have been tested on different browser platforms so it could save you from some compatibility testing.

它似乎已经在不同的浏览器平台上进行了测试,因此它可以帮助您避免一些兼容性测试。

If you want a more comprehensive numeric mask support, you can use the excellent autoNumeric from decorplanit.com . Their webpage is full of examples.

$(document).ready(function(){


    $('input.number').keyup(function(event){
      // skip for arrow keys
      if(event.which >= 37 && event.which <= 40){
          event.preventDefault();
      }
      var $this = $(this);
      var num = $this.val().replace(/,/gi, "").split("").reverse().join("");

      var num2 = RemoveRougeChar(num.replace(/(.{3})/g,"$1,").split("").reverse().join(""));

      // the following line has been simplified. Revision history contains original.
      $this.val(num2);});});

    function RemoveRougeChar(convertString){


    if(convertString.substring(0,1) == ","){

        return convertString.substring(1, convertString.length)            

    }
    return convertString;

}

I tried to improve on j0k's code by instead using blur and focus events rather than keyup: http://jsfiddle.net/AqDda/

我尝试通过使用模糊和焦点事件而不是键盘来改进j0k的代码:http://jsfiddle.net/AqDda/

^ Try input A (standard type="number") versus input B (type="text" with JavaScript and some 'invalid' styling).

^尝试输入A(标准类型=“数字”)与输入B(使用JavaScript的类型=“文本”和一些“无效”样式)。

$('input.number').on("focus",function(e){
    var $this = $(this);
    var num = $this.val().replace(/,/g,"");
    $this.val(num);

}).on("blur", function(e){
    var $this = $(this);
    var num = $this.val().replace(/[^0-9]+/g, '').replace(/,/gi, "").split("").reverse().join("");     
    var num2 = RemoveRougeChar(num.replace(/(.{3})/g,"$1,").split("").reverse().join(""));
    $this.val(num2);
});
