JavaScript 用空格分割字符串 [英] JavaScript split String with white space

问题描述

我想拆分一个字符串，但我想保留如下空格:

I would like to split a String but I would like to keep white space like:

var str = "my car is red";

var stringArray [];

stringArray [0] = "my";
stringArray [1] = " ";
stringArray [2] = "car";
stringArray [3] = " ";
stringArray [4] = "is";
stringArray [5] = " ";
stringArray [6] = "red";

我该怎么做?

谢谢！

推荐答案

您可以在空白处拆分字符串，然后重新添加它，因为您知道它位于每个条目之间.

You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.

var string = "text to split";
    string = string.split(" ");
var stringArray = new Array();
for(var i =0; i < string.length; i++){
    stringArray.push(string[i]);
    if(i != string.length-1){
        stringArray.push(" ");
    }
}

更新:删除了尾随空格.
