修改字符串在JavaScript

Question

數組這是我的JavaScript數組

["200.00 K","200.50 K","300.00 K" ,"300.50 K","400.00 K","400.50 K"] 

解析這個數組我需要得到這樣的

["200 K","200.5 K","300 K" ,"300.5 K","400 K","400.5 K"] 

後，我使用的原型
請幫幫我？

Answer 1

var a = ["200.00 K","200.50 K","300.00 K","300.50 K","400.00 K","400.50 K"]; 
for (var i = 0; i < a.length; i++) { 
    a[i] = a[i].replace(/(?:(\.\d*[1-9])|\.)0+ /, "$1 "); 
} 

之後，a是

200 K,200.5 K,300 K,300.5 K,400 K,400.5 K 

Answer 2

像這樣的事情

for(i=0;i<arrayName.length();i++){ 
    arrayName[i]=parseFloat(arrayName[i])+ " K"; 
} 

Answer 3

myArray = myArray.map(function (item) { 
    var n = parseFloat(item); 
    return n + " K"; 
}); 

對於舊的瀏覽器， read this 其實我覺得原型自動爲您完成此。

Answer 4

在所有瀏覽器的工作原理是在其他的答案的變種，

var a = ["200.00 K","200.50 K","300.00 K" ,"300.50 K","400.00 K","400.50 K"]; 
var b = []; 
for (var i = 0; i < a.length; i++) 
    b.push(parseFloat(a[i]) + " K"); 

b哪裏是所得陣列。
