    Default regex not working properly

    regex not working properly


    I want to validate a text field using only a single regex which validates the text as a Number which is 0- 4 digits in length.

    new Ext.form.TextField(
    {
    id: 'T1',
    regex: /[0-9]\{0,4\}/,
    regexText: 'Should be Number between 0 - 9999',
    validator:function(value){
    re = new RegExp('/[0-9]\{0,4\}/');
    return re.test(value);
    }
    });

    new RegExp('/[0-9]\{0,4\}/') ?

    Read a Javascript book or online tutorial. That's wrong.

    The regex config you specify will check that the input contains a string of digits between 0 and 4 characters long.

    It will always contain a string of digits between 0 and 4 characters long. Think about it.

    just to be clear and to confirm @Animal's post, the string 'ABCD' contains a string of numbers of length 0 (in five places).

    Yes, "contains" !== "is a"

    Those two conditions require different regular expression coding. You are on track, but not there.
