Formular

Du kan checke om alle felter er udfyldt inden der sendes.
http://www.html.dk/artikler/00016/

jeg bruger denne i selve formen:

<input type="hidden" name="required" value="Navn,Adresse,PostnrBy,Telefon,Email"> hvor value er navnene på felterne der skal udfyldes unden man kan sende den.

Men er ikke 100 på om FP har denne mulighed

Da min formular har flere afkrydsningsfelter / svarmuligheder, kan jeg ikke lave de enkelte felter obligatorisk ex. ja / nej eller ved ikke.

Du skal have lavet noget validering! Dette går ind og tjekker om alle dine felter er fyldt inden de sendes!!

Brug evt. noget java script til dette!!

It is possible using JavaScript. It really depends on what form fields you have present in your form as to what JavaScript form validation you perform.

If you are not interested in support for Netscape Navigator 2 or Microsoft Internet Explorer 3, then you can write some generic code that interrogates all the form elements and depending on their type performs relevant validation.

If you must support Netscape Navigator 2 and Internet Explorer 3 then you need some clue as to what each form elements type is, by using the form elements name.

The following provides a way for all browsers:

<script language="JavaScript"><!--
function validateValues(what) {
    var valid = true;
       
    var checkBoxes = false;
    var checkboxChecked = false;
       
    var radioButtons = false;
    var radioChecked = false;

    for (var i=0, j=what.elements.length; i<j; i++) {
        myName = what.elements[i].name;
        if (myName.indexOf('radio') > -1) {
            radioButtons = true;
            if (what.elements[i].checked) radioChecked = true;
        }
        if (myName.indexOf('checkbox') > -1) {
            checkBoxes = true;
            if (what.elements[i].checked) checkboxChecked = true;
        }
        if (myName.indexOf('hidden') > -1 || myName.indexOf('password') > -1 || myName.indexOf('text') > -1)
            if (what.elements[i].value == what.elements[i].defaultValue) valid = false;
        if (myName.indexOf('select') > -1)
            if (what.elements[i].selectedIndex == 0) valid = false;
    }

    if ((checkBoxes && !checkboxChecked) || (radioButtons && !radioChecked)) valid = false;

    if (!valid)
        alert('Form not completely filled');

    return valid;
}
//--></script>

<script language="JavaScript1.1"><!--
function validateValues(what) {
    var valid = true;
       
    var checkBoxes = false;
    var checkboxChecked = false;
       
    var radioButtons = false;
    var radioChecked = false;
       
    for (var i=0, j=what.elements.length; i<j; i++) {
        myType = what.elements[i].type;
        if (myType == 'radio') {
            radioButtons = true;
          if (what.elements[i].checked) radioChecked = true;
        }
        if (myType == 'checkbox') {
            checkBoxes = true;
            if (what.elements[i].checked) checkboxChecked = true;
        }
        if (myType == 'hidden' || myType == 'password' || myType == 'text' || myType == 'textarea')

Det nemmeste er nok ikke at bruge en submit knap og bare en almindelig knap.

EKS:

<form method="POST" action="side.asp" name="formen">
  <p><input type="radio" value="V1" name="R1"> Spørgsmål ?</p>
  <p><input type="radio" value="V2" name="R2"> Spørgsmål ?</p>
