How would you get an array of numbers from a javascript string? Say I have the following:
var slop = "I bought 3 but 8 4.2 of them, mmmmhghrhghrghghrgh456";
How could you get the following array:
nums = [3, 8, 4.2, 456];
Note: I'd like to not have to use jQuery if possible.
You can do this :
var s = "I bought 3 but 8 4.2 of them, mmmmhghrhghrghghrgh456";
var nums = s.split(/[^\d\.]+/).map(parseFloat)
.filter(function(v){ return v===v });
Result : [3, 8, 4.2, 456]
Basic regex fetching:
var string = 'I bought 3 but 8 4.2 of them, mmmmhghrhghrghghrgh456 hello.45';
var result = string.match(/((?:\d+\.?\d*)|(?:\.\d+))/g);
console.log(result);
Result:
["3", "8", "4.2", "456", ".45"]
Edit
Updated to work with non-prefixed 0.xx decimals. If that's not what you want, this was the old regex to match it as (ignore dot) full numeral:
var result = string.match(/(\d+\.?\d*)/g);
Old Result:
["3", "8", "4.2", "456", "45"]
