Javascript function to identify space in a value

[sharatcg]

Hello All,

I want to identify if there is a space in a field value. For e.g. '0 ' is not same as '0'. I want to convert this '0 ' to '0' to do some validations. How is it possible in javascript?

Thanks & Regards,

Sharat

Identify, or convert? Two different things really.

If you want to identify:

if(/ /.test(value))
Do something here if there is a space in value

If you want to convert:

value = value.replace(/ /g, '');

Which will strip all spaces from value before any further processing.

You can use regex as John described above, or you can use a filter:

var Functional = {
  filter: function(p, a) {
    for (var i = 0, n = a.length, r = []; i < n; ++i)
      if (p(a[i], i))
        r[r.length] = a[i];

    return r;
  }
};

function unspace(s) {
  return Functional.filter(function(v) { return v !== ' '; }, s.split("")).join("");
}

unspace(" 0 0 "); // "00"

Regex is more flexible, but the filter is generally faster, especially in small cases like this one.

function(v) { return v !== ' '; }

Oops, yes. Indeed.
