Javascript/Jquery将字符串转换为数组 [英] Javascript/Jquery Convert string to array

问题描述

我有一个字符串

var traingIds = "${triningIdArray}";  // ${triningIdArray} this value getting from server 
alert(traingIds)  // alerts [1,2]
var type = typeof(traingIds ) 
alert(type)   // // alerts String

现在我想将其转换为数组，以便可以迭代

now i want to convert this to array so that i can iterate

我尝试过

var trainindIdArray = traingIds.split(',');
$.each(trainindIdArray, function(index, value) { 
    alert(index + ': ' + value);   // alerts 0:[1 ,  and  1:2]
});

如何解决这个问题?

推荐答案

假设情况似乎是这样，${triningIdArray}是服务器端占位符，已替换为JS数组文字语法，只是失去了引号.所以:

Assuming, as seems to be the case, ${triningIdArray} is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:

var traingIds = ${triningIdArray};

不是

var traingIds = "${triningIdArray}";
