划分数千个字段

Question

当我在文本（或数字）字段中发送数字时，我需要用逗号将数字除以数字。

例

1. instead of it saying “1000” make it say “1,000”. 
2. “1000000” make it say “1,000,000”. 

Answer 1

使用脚本

$(document).on('keyup', '.Amount', function() { 
    var x = $(this).val(); 
    $(this).val(x.toString().replace(/,/g, "").replace(/\B(?=(\d{3})+(?!\d))/g, ",")); 
});

片段的例子下面

$(document).on('keyup', '.Amount', function() { 
 
    var x = $(this).val(); 
 
    $(this).val(x.toString().replace(/,/g, "").replace(/\B(?=(\d{3})+(?!\d))/g, ",")); 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<form> 
 
Enter Amount:<input class="Amount" type="Amount" /> 
 
</form>

这可以帮助你

window.onload=function(){ 
 
    var numberinput=document.getElementById('number'); 
 
    numberinput.addEventListener('change',changedValue); 
 
} 
 

 
function changedValue(){ 
 
    var input=this.value 
 
    var number=parseInt(input,10); 
 
    if(number>=1000) 
 
    { 
 
     
 
    var numbersArray = input.toString().split("."); 
 
    numbersArray[0] = numbersArray[0].replace(/\B(?=(\d{3})+(?!\d))/g, ","); 
 
    this.value= numbersArray.join("."); 
 
    } 
 
}

<input type="text" id="number" >

希望这有助于

$('input.number').keyup(function(event) { 
 

 
     // skip for arrow keys 
 
     if(event.which >= 37 && event.which <= 40) return; 
 

 
     // format number 
 
     $(this).val(function(index, value) { 
 
     return value 
 
     .replace(/\D/g, "") 
 
     .replace(/\B(?=(\d{3})+(?!\d))/g, ",") 
 
     ; 
 
     }); 
 
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> 
 
    <input class="number">
