Sert string field to minimum characters and numbers only

[Thomas G]

Hi,

I have an onChange Client Script ensuring that minimum eight characters are entered in a string field.

It looks like this:
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var myFieldValue = g_form.getValue('u_account_number');
if (myFieldValue.toString().length < 8 ) {
g_form.setValue('u_account_number','');
alert('Please enter 8 or more characters.');}
}

Now I want to expand that so that only numbers from 0 to 9 should be possible. How can I achieve that?

Best regards
Thomas

Hi @Thomas G,

You may need to use regex in here.
EX: var reg = /^\d+$/;
reg.test('1234567')

Hi Thomas

Did you try the regex option suggested by Jerick, that works.

or you can also do this too which is same as Validation regex but through script.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var regexp = /^[+]?\d*$/;
    var myFieldValue = g_form.getValue('u_account_number');
    if (regexp.test(newValue)) {
        if (myFieldValue.toString().length < 😎 {
            g_form.setValue('u_account_number', '');
            alert('Please enter 8 or more characters.');
        }
    } else {
        g_form.setValue('u_account_number', '');
        alert('Please enter Numbers');
    }
}

Hi Rohila,

I tried that. It gives me a parsing error (Unexpected token) in line 9. The line with g_form.setValue('u_account_number', '');

Hi 

Try this.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var regexp = /^[+]?\d*$/;
    var myFieldValue = g_form.getValue('u_account_number');
    if (regexp.test(newValue)) {
        if (myFieldValue.toString().length < 😎 {
            g_form.clearValue('u_account_number');
            alert('Please enter 8 or more characters.');
        }
    } else {
          g_form.clearValue('u_account_number');
        alert('Please enter Numbers');
    }
}

Hi again, 

By adding the number 8 after < in the line: 

if (myFieldValue.toString().length <

 This one seems to work. Thank you! 🙂

Best regards
Thomas
