[Vinya Jakkula]

Hi Team,

function onLoad() {

    var control = g_form.getControl('comments');

    //Set its onkeyup method

    control.onkeyup = isMaxLength;

}

function isMaxLength() {

    var mLength = 170;

    var control = g_form.getControl('comments');

    if (control.value.length > mLength) {

        g_form.hideErrorBox('comments');

        g_form.showErrorBox('comments', 'You have reached the maximum character limit for this field.');

        control.value = control.value.substring(0, mLength);

    } else {

        g_form.hideErrorBox('comments');

    }

}

Hi Vinya,

Why not limit it by simplying setting the max_length attribute as anyways, the script of yours is executing onLoad and not onChange or onSubmit.

But for multiline text max length is not working.
