修改字符串在JavaScript

Question

数组这是我的JavaScript数组

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

解析这个数组我需要得到这样的

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

后，我使用的原型
请帮帮我？

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 "); 
} 

之后，a是

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

Answer 2

像这样的事情

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"; 
}); 

对于旧的浏览器， read this 其实我觉得原型自动为您完成此。

Answer 4

在所有浏览器的工作原理是在其他的答案的变种，

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哪里是所得阵列。
