Regular Expression to find a value in a string

I've got a bunch of strings that look like this:

Using javascript, how can I get an array of 10,4,77? These will be values of input fields all with the class form-text so I have the option of iterating of them.

Thanks, Howie

Lets say you have the given strings in array. Then using Array.map you can retrieve the id's 

var a = ["This is string 1 [id:10]", "This is string 2 [id:4]", "This is string 3 [id:77]"];

var result = a.map(function (item) {
    return /.*?\[id:([\d]{1,})\]/g.exec(item)[1];
});

console.log(result);

You could do something like this:

var test = "[id:10]";
var result = test.split(":")[1].split("]")[0];
//result should have 10
