将逗号分隔的字符串转换为 JavaScript 数组

Question

I have this string:

"'California',51.2154,-95.2135464,'data'" 

I want to convert it into a JavaScript array like this:

var data = ['California',51.2154,-95.2135464,'data'];

How do I do this?

I don't have jQuery. And I don't want to use jQuery.

Answer 1

Try:

var initialString = "'California',51.2154,-95.2135464,'data'";
var dataArray = initialString .split(",");

Answer 2

Use the split function which is available for strings and convert the numbers to actual numbers, not strings.

 var ar = "'California',51.2154,-95.2135464,'data'".split(","); for (var i = ar.length; i--;) { var tmp = parseFloat(ar[i]); ar[i] = (!isNaN(tmp)) ? tmp : ar[i].replace(/['"]/g, ""); } console.log(ar)

Beware, this will fail if your string contains arrays/objects.

Answer 3

Since you format almost conforms to JSON syntax you could do the following :

var dataArray = JSON.parse ('[' + initialString.replace (/'/g, '"') + ']');

That is add '[' and ']' characters to be beginning and end and replace all "'' characters with '"'. than perform a JSON parse.
