update textfield value when clicking submit button 1

[optjco]

Is it possible to change the value of a textfield when a submit button is clicked to update a table

<input type="submit" value="Update table!" onclick="this.form.elements['txtfld'].value = 'New value!';">

Chessbot,
I think I may have mislead you slightly.

I have an update form where 2 textareas are populated(txtCause & txtAction) also I have a read only field(txtStatus) that is populated earlier from an Insert form with the following text("Outstanding").

What I need is that when the two fields are populated and before the update is submitted then the field ("Outstanding") is changed to ("Pending")

Set the onclick to call a function.

That function will check the length of the two other text fields.

If they both have values, then set the value of your other text field, using the code snippet from Chessbot's post.

Guys,
I managed to get some code working by editing a script I found however I am sure there is someone out there that could perhaps help me streamline it

<script Language = "javascript" >
function checkBoxes(){
  boxArr = new Array("txtCause")
  dataFound = "Outstanding"
  for (x=0; x<boxArr.length; x++){
    boxVal = eval ("document.frmPending." + boxArr[x] + ".value")
    if (boxVal != ""){
      dataFound = "Pending"
    }
  }
  document.frmPending.txtStatus.value = dataFound
}

</script>

I am then calling the function with this

onSubmit="checkBoxes()"

Regards

Olly

If that works, consider changing

    boxVal = eval ("document.frmPending." + boxArr[x] + ".value")

to

    boxVal = document.frmPending.elements[boxArr[x]].value;

to decrease processing time.
