insert dynamic data based on checkbox value

[tamnet]

I am using the follwoing code to try and insert data into 2 text fields if a checkbox is "checked" otherwise the fields are blank, but i do not seem to be able to find the correct syntax to make it work ?

<script language="JavaScript">
function showVal(){
  if (document.frmDesignDetails.chkDA.unchecked == True){
    document.frmDesignDetails.txtDABy.value = ""
    document.frmDesignDetails.txtDAD.value = ""
  }
  else{
    document.frmDesignDetails.txtDABy.value = "<%=ValImage%>"
    document.frmDesignDetails.txtDAD.value = "<%=strUKDate%>"
  }
}
</script>

Could anyone please help

<script language="JavaScript">
function showVal(){
  if ([b][COLOR=red]![/color][/b]document.frmDesignDetails.chkDA.[b][COLOR=red]checked[/color][/b]){
    document.frmDesignDetails.txtDABy.value = ""
    document.frmDesignDetails.txtDAD.value = ""
  }
  else{
    document.frmDesignDetails.txtDABy.value = "<%=ValImage%>"
    document.frmDesignDetails.txtDAD.value = "<%=strUKDate%>"
  }
}
</script>

Additionally, as a side note, when checking to see if a value is equal to the boolean value "true" it is not necessary to put the "== true". If you decide to put it in anyway (if you think it's easier to read that way for instance), then make sure not to capitalize the T. Javascript is case sensitive, and the keyword is all lowercase letters: true

OK,
I have this working now with the following code

<script language="JavaScript">
function showVal(){
  if (document.frmDesignDetails.chkDA.checked){
    document.frmDesignDetails.txtDABy.value ="<%=ValImage%>"
    document.frmDesignDetails.txtDAD.value ="<%=strUKDate%>"
  }
  else{
    document.frmDesignDetails.txtDABy.value = ""
    document.frmDesignDetails.txtDAD.value = ""
  }
  
}
</script>

Now I need to replicate this for another checkbox and 2 other textfields however even though i have copied the code to create another function i cannot seem to get it to work. this is the other code

<script language="JavaScript">
function showValues(){
  if (document.frmDesignDetails.chkSTD.checked){
    document.frmDesignDetails.txtDRBy.value ="<%=ValImage%>"
    document.frmDesignDetails.txtDRD.value ="<%=strUKDate%>"
  }
  else{
    document.frmDesignDetails.txtDRBy.value = ""
    document.frmDesignDetails.txtDRD.value = ""
  }
}
</script>

and i have placed this for the checkbox

onChange="showValues()"

does anyone have any ideas why this will not work ??

Also would it be possible to carry out both sets of code from within one function ??

OK,
sorted the first bit out it was me being dumb.

onChange="showValues()"

only changes the values when you move to another field. Silly me.

changed it to

onClick="showValues()"

and it works fine.

however i would be interested to know if i could merge the two functions into one if someone has any suggestions
