在javascript中获取2个字符之间的子字符串

First of all, I tried to search it on SO but couldn't find a solution. I have a string

var str = 'a:5:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:1:"3";i:3;s:1:"4";i:4;s:1:"5";}';

I want to grab all numbers between " " as an array in javascript. I tried this suggested on one of the SO questions.

console.log(str.split(/[""]/));

but this outputs

["a:5{i:0;s:1:", "1", ";i:1;:", "2", ";i:2;s:1:", "7", ";i:3;s:1:", "4", ";i:4;s:1:", "5", ";}"]

which is not exact.

Actually that above string is an array of PHP stored in MemcacheD and I am retrieving it in Node.JS and that's why I can't use json_encode or so. I am not good at Regex. So Experts please show some shine on it.

The result of above string should be an array or string like this

str = "1,2,3,4,5"; 

or an array like

array = [1,2,3,4,5];

So, this is a PHP serialized string. There is a version of unserialize available for javascript in the php.js project.

So using that function.

Javascript

var str = 'a:5:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:1:"3";i:3;s:1:"4";i:4;s:1:"5";}';

console.log(unserialize(str));

Output

["1", "2", "3", "4", "5"] 

On jsFiddle

And if you are using nodejs then you could also consider a module like php-unserialize

str.match(/"\d+"/g).join().replace(/"/g,'')
// "1,2,3,4,5"

function match_all(str, re) {
    var ret = [], v;
    while(v = re.exec(str)) {
        ret.push(v[1]);
    }
    return ret;
}
var str = 'a:5:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:1:"3";i:3;s:1:"4";i:4;s:1:"5";}';
var numbers = match_all(str, /"(\d+)"/g);
console.log(numbers);
//to convert the result to ints
console.log(numbers.map(function(v) { return +v; }));
