JavaScript with Ruby

我使用的是Rails 4.1.6 &Ruby 2.1.5

在Javascript中我取了一个变量x

var x= ravi,kant,ashish

我想显示如下的输出

["ravi","kant","ashish"]

我写这个代码

var x = ravi,kant,ashish
var z = x.map(function(p){ return '"' + p + '"'; }).join(',');

如果我把alert(z);输出变成"ravi","kant","ashish"如果我输入alert(z[0])，它应该是"ravi"但它是"(double quotes)

请告诉我如何得到输出。

您需要使用split() 

var str = "How are you doing today Ravi?";
var res = str.split(" "); // ["How", "are", "you", "doing", "today", "Ravi?"]
res[0] // "How"

以你为例

var x= "ravi,kant,ashish";
y = x.split(","); // ["ravi","kant","ashish"]
y[0]; // "ravi"

希望有帮助!
