[Vinya Jakkula]

Hi Team can anyone help me!! Iam using below script to limit the characters while using entering the text.it is working in native UI. But not in portal.as I know get control will not work in portal. Can anyone help me please.

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 Jakkula 

Here is what I got:

Article 

function onSubmit() {
	var maxLength = 290; // Add desired max length here
	var varName = 'full_description'; // Add variable name here
	var multi = g_form.getValue(varName);
	var len = multi.length;
	if(len > maxLength){
		var str = multi.slice(0, maxLength);
		g_form.setValue(varName, str);
		g_form.showFieldMsg(varName, 'Max length of ' + maxLength.toString() + ' exceeded for this field.', 'error');
                return false;
	}
}

With above script it will delete the user entered the text if it is beyond the limit. I need to on key while user typing the text.
