Array form element validation in JS

Question

I'm trying to validate form array element below but getting error. I wonder if it is set as an array because other normal elements are being validated without a problem.

Thanks in advance

ERROR

TypeError: document.formABC.textQualificationSet is undefined

JS

var textQualSubject = document.formABC.textQualificationSet[0]["Qual Subject"].value;

    if(textQualSubject == ""){
        alert("ERROR: Please enter at least first Qualification Subject");
        return false;
    }

HTML

<input type="text" name="textQualificationSet[0][Qual Subject]" value="" />

Have you looked at a validation library? parsleyjs.org/documentation.html Your users and any developer looking at this after you will thank you! — CodingIntrigue

you are doing it wrong it, must be like this

document.getElementsByName('textQualificationSet[0][Qual Subject]')[0].value;
