如何将字符串（包含位置）转换为数组

Question

I have a string which contains location:

var string = "[ 30.733315, 76.77941799999999,City,6,10/28/2013 10:28:39 AM]"

How to convert this to an array, so that i can get

arr[0] = 30.733315,
arr[1] = 76.77941799999999 so on.

String.split() is not working here.

Answer 1

Split on [ , ] and , .

] must be escaped in the split regex

var arr = string.split(/[[,\]]/).filter(function(el) { return el.trim(); })

Array.prototype.filter is required to remove empty strings from the array.

A more readable version of filter would be:

arr.filter(function(el) {
  return el.trim().length === 0;
});

Answer 2

var string = "[ 30.733315, 76.77941799999999,City,6,10/28/2013 10:28:39 AM]";
string = string.replace('[',"['");
string = string.replace(']',"']");
string = string.replace(',',"','","gi");

console.log(string);
arr=eval(string);

console.log(arr);

Answer 3

Try this

var mystring= "[ 30.733315, 76.77941799999999,City,6,10/28/2013 10:28:39 AM]"
var list = mystring.split(',');

Output:

for(var i = 0; i < list.length; i++)
{
  alert(list[i]);
}

String.split Splits a String object into an array of strings by separating the string into substrings.

Answer 4

A cross-browser solution:

var string = "[ 30.733315, 76.77941799999999,City,6,10/28/2013 10:28:39 AM]";

var arr = string.replace(/\[|\]/g,'')
                .replace(/ /g,'')
                .split(',');
