數字格式通過.toString（）

Question

新手問題：我如何將numberWithCommas傳遞給我的值，使我的號碼格式正確？代碼對我來說太複雜了。它正在工作，我只需要格式化數字。謝謝！

<script type="text/javascript"> 

function numberWithCommas(x) { 
return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","); 
} 

if(!localStorage.Val1){ 
    localStorage.Val1 = 1412015; 
    localStorage.Val2 = 20000; 
    localStorage.Val3 = 20000; 
} 

    setInterval(function() { 
    var popcounter = document.getElementById('pop'); 
    var ethanolcounter = document.getElementById('ethanol'); 
    var meatlcounter = document.getElementById('meat'); 


localStorage.Val1 = parseInt(localStorage.Val1,10)+1; 
     localStorage.Val2 = parseInt(localStorage.Val2,10)+1000; 
     localStorage.Val3 = parseInt(localStorage.Val3,10)+1000; 

     popcounter.innerHTML = localStorage.Val1,10; 
     ethanolcounter.innerHTML = localStorage.Val2; 
     meatlcounter.innerHTML = localStorage.Val3; 

    },1000); 

</script>

你在問怎樣調用JavaScript function？那麼，假設您的功能正常工作：

popcounter.innerHTML=numberWithCommas(localStorage.Val1) 
//repeat for Val2 and Val3
