check for blank form

<form name="form1" onsubmit="return validate(this);">

<input type="text" name="text1">
<input type="text" name="text2">
<input type="submit" value="submit!">
</form>

<script type="text/javascript">
function validate(formObj){
  if (formObj.text1.value == ''){
    alert('please input value of text1');
    formObj.text1.focus();
    return false;
  }else   if (formObj.text2.value == ''){
    alert('please input value of text2');
    formObj.text2.focus();
    return false;
  }
  return true;
}

</script>

If I use this script will I need to check each individual field to see if all of them are empty?

I am not good with javascript at all. I know just the basics so excuse my dumbness here, but do I just add the code to my html code as you have it or do I need to rename something. My form name is jobapp.

DO I ADD THIS BEWTEEN HEAD TAG?
<script type="text/javascript">
function validate2(formObj){
  var i=0;
  var formChilds = formObj.childNodes;
  var allBlank = true;
  for (i=0; i<formChilds.length;i++){
    if (formChilds[i].nodeName=='INPUT' && formChilds[i].type == 'text'){
      if (formChilds[i].value!=''){
        allBlank = false;
      }
    } 
  }
  
  if(allBlank){
    alert('no one field was inputted');
  }
  return (!allBlank);
}
 
</script>
 
ADD THIS TO FORM TAG?
onsubmit="return validate2(this);"

I just tried it and I get an alert when trying to submit the blank form. How many text boxes have to be filled in before the form can be submitted? Because I tried filling out two text bixes and hitting submit and I still got the alert.

example of #24083518
it only alert when all of field are empty..
do I need to rename something? No, the formObj passed into function validate2
How many text boxes have to be filled in before the form can be submitted? more than zero (1,2,3,4.....)
Because I tried filling out two text bixes and hitting submit and I still got the alert. ?  I tested on ff3, ie6.. that's okey....

And yes, put the script in the head and modify your form tag as shown in the example. You need to scroll to see the form

Thanks. I get it now. But how do I fix ithe problem with alert? It should only pop up if the form is blank.

The script above is not what I used. I was using the one with childNodes. It's working now. Thank you you both so much for your help and patience. I appreciate it!

I know you did not, I just rewrote the script for you :)
