        g_form.showFieldMsg("student_id", "This field has a maximum character limit of 4000. Please revise and submit.", "error");
        g_form.addErrorMessage("You have exceeded the 4000 character limit. Please revise and submit.");
        return false;

    }

Hello,

Please check if the below code looks good to you and try once:

function onSubmit() {
    var isValid = true;
    var fieldNames = {
        "student_id": "Y",
        "student_id1": "Y",
        "student_id3": "Y"
    };
    for (var fname in fieldNames) {
        var fieldValue = g_form.getValue(fname);
        if (fieldValue && fieldValue.length > 4000) {
            g_form.showFieldMsg(fname, "This field has a maximum character limit of 4000. Please revise and submit.", "error");
            if (isValid)
                isValid = false;
        }
    }
    if (!isValid) {
        g_form.addErrorMessage("You have exceeded the 4000 character limit. Please revise and submit.");
        return false;
    }
}

With Array:

function onSubmit() {
    var isValid = true;
    var fieldNames = ["student_id","student_id1","student_id3"];
    for (var fname in fieldNames) {
        var fieldValue = g_form.getValue(fieldNames[fname]);
        if (fieldValue && fieldValue.length > 4000) {
            g_form.showFieldMsg(fieldNames[fname], "This field has a maximum character limit of 4000. Please revise and submit.", "error");
            if (isValid)
                isValid = false;
        }
    }
    if (!isValid) {
        g_form.addErrorMessage("You have exceeded the 4000 character limit. Please revise and submit.");
        return false;
    }
}

Please mark this as helpful/correct, if it answer your question.

Thank you so much for your help 🙂

if i have to customise the error message

 g_form.addErrorMessage("You have exceeded the 4000 character limit . Please revise and submit.");

instead i want array values which exceed more than 4000 character limit with comma separated value?

Error message :

You have exceeded the 4000 character limit + fieldValues

could you please help me for adding it in error message

Hi Mahendra,

Your script helped me as well. Thank you so much for that.

I have similar requirement with little change in error message.

For example - I have 4 fields a,b,c,d exceeding limit of 4000 characters. I need to show error message in comma separated way.

Error Message should be in below way

" You have exceeded the 4000 characters for fields a,b,c,d. Please revise and submit."

Can you please help me in achieving this.

Thanks in advance....
