display return value of prompt box to php page

godhsf80 · November 25th, 2003, 09:54 PM

when the user clicked the second or third radio button, the prompt box will ask for the name. then the name is will be displayed on the text box when the ok button of the prompt box is clicked. However, I'm not able to display the value in the text box.

Please correct my code below.

<HTML>
<HEAD>
<script type="text/javascript">
function function1(){
var name = prompt("Please enter your name","")
if (name != null && name != "")
{
return name;
}
}
</script>
</HEAD>
<BODY>
<input type="radio" name="radio1" value="one" >one
<input type="radio" name="radio1" value="two" onclick="function1()">two
<input type="radio" name="radio1" value="three" onclick="function1()">three
<input type="hidden" name="hidden1" value="name">
</BODY>
</HTML>

I don't see anywhere in your code where you'd display that name.

Notes:

1) function1() just returns the name entered in the checkbox.
2) function1() is ONLY called by your radio buttons onClick event, and nothing is done with the return value.

That means you're just throwing the value away -- you're not DOING anything with it.

Your hidden input field has a value of "name". That's just a string, "name". It's in no way related to the local variable you define within the scope of function1().

Perhaps you meant to do this:

function function1()
{
    var name = prompt("Please enter your name", "");
    if ((name != null) && (name != ""))
    {
        document.form1.hidden1.value = name;
    }
}

See the difference? You're actually DOING something with the value returned from the prompt box -- you're assigning the value property of the hidden1 object (which translates into the value attribute of the hidden1 element in HTML).

You need to wrap your form input elements in a <form name="form1"> tag for this to work.

You've been asking a lot of JavaScript questions lately -- remember that this is a PHP forum, so in the future you should direct your JavaScript questions to the appropriate forum -- there's several to choose from.

Thanks!it works.
Sorry for the trouble because i was new here and doesn't realize that there's a javascript forum.

It's not a problem, I just think you'll get much better answers from the JS gurus in the other forums than you will from PHP gurus who dabble in JS when it suits us. =)

Take care,
