问题描述

我在我的网页中使用了大量HTML 5输入控件。我的要求之一是有一个带有货币功能的文本框。为此我尝试了这个:

 < input type =numberpattern =(d {3})([。 ])(d {2})/> 

这允许我输入类似10,000.00的值



<但它仍然不符合我的所有要求。我想,如果用户输入10000
,它应该将其转换为10,000像onblur这样的货币格式。



当我从输入类型中读取值我的Javascript,它应该给我一个浮点数,而不是一个字符串值,我不能用它来计算而不解析。

解决方案

解决方法是使用额外的 input type =text

HTML

 < input type =textid =userinputpattern =[0-9] *> 
< br>
< input type =numberid =number>

JS

  document.getElementById(userinput)。onblur = function(){

//数字格式用户输入
this.value = parseFloat(this.value.replace (/,/ g,))
.toFixed(2)
.toString()
.replace(/ \B(?=(\ d {3})+ (?!\d))/ g,,);

//将数字值设置为数字输入
document.getElementById(number)。value = this.value.replace(/,/ g,)

}

I am using lots of HTML 5 input controls in my pages. One of my requirement is to have a textbox with currency feature. For this i tried this:

<input type="number" pattern="(d{3})([.])(d{2})" />

This allows me to type values like 10,000.00

But still all its not meeting all my requirements. I want that if the user types in 10000 it should convert it to currency format like 10,000 onblur.

And when i read the value from the input type in my Javascript, it should give me a float instead of a string value which i cannot use to calculate without parsing.

解决方案

Here's a workaround with an additional input type="text":

http://jsfiddle.net/UEVv6/2/

HTML

<input type="text" id="userinput" pattern="[0-9]*">
<br>
<input type="number" id="number">

JS

document.getElementById("userinput").onblur =function (){    

    //number-format the user input
    this.value = parseFloat(this.value.replace(/,/g, ""))
                    .toFixed(2)
                    .toString()
                    .replace(/\B(?=(\d{3})+(?!\d))/g, ",");

    //set the numeric value to a number input
    document.getElementById("number").value = this.value.replace(/,/g, "")

}
