JavaScript - Forms I Agree Before Entry
JavaScript will only let you enter your name in this form if you indicate you agree to the terms by first clicking the I Agree radio button. If you agree, you can enter your name. But, if you disagree, you will not be able to enter or edit your name. When you disagree, the box is 'locked.' Useful if you require your visitors to accept a disclaimer before downloading software or visiting a section of your members-only site.

 

<!-- TWO STEPS TO INSTALL AGREE BEFORE ENTRY:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document  -->

<HEAD>

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin

agree = 0;  // 0 means 'no', 1 means 'yes'

//  End -->
</script>
</HEAD>

<!-- STEP TWO: Copy this code into the BODY of your HTML document  -->

<BODY>

<center>
<form name=enableform>
You can only enter your name if you agree to the terms. (just a demo)<br>
<br>
<input type=radio name='enable' value='agree' onClick="agree=1; document.enableform.box.focus();">I agree<br>
<input type=radio name='enable' value='disagree' onClick="agree=0; document.enableform.box.value='';">I disagree<br>

Please enter your name: 

<input type=text name=box onFocus="if (!agree)this.blur();" onChange="if (!agree)this.value='';" size=12>
<br>
<br>
<input type=submit value="Done!">
</form>
</center>
