Hi guys,
I don't know whether this is a HTML or Javascript question, but i decided to put it here.
This is my problem:
I am making a simple HTML form that posts a random number (generated by Javascript) on my website, but I'm having trouble assigning the random number to the form.
This is what I have right now: -
-
-
-
<html>
-
-
<head>
-
-
<title>xxx</title>
-
-
<script type="text/javascript">
-
-
function changejweet()
-
{
-
-
document.reply.topic.value = "***RANDOM NUMBER***";
-
document.reply.action = "http://site.com/post_reply/" +***RANDOM NUMBER***";
-
-
}
-
-
-
function randomnumber()
-
{
-
document.getElementById("rand").value = Math.round((1000000 - 500000) * Math.random() + 1);
-
}
-
-
</script>
-
-
</head>
-
-
<body onload=changejweet();>
-
-
<form name="reply" action="site.com/post_reply/" method="post">
-
-
<input type="hidden" name="topic" value="1">
-
<input type="hidden" name="skipVerbose" value="TRUE">
-
<input type="submit" name="submit" value="Click to send random number">
-
-
</form>
-
-
</body>
-
-
</html>
-
The ***RANDOM NUMBER*** is the values that I want to change into the random number.
I already tried: -
document.reply.topic.value = rand;
-
document.reply.action = "http://site.dom/post_reply/" + rand;
But that didnt work.
I am a javascript/HTML beginner and would like to know how to do this.
Can someone help me?
Thanks in advance !

Welcome to TSDN.
You don't have an element with id "rand". Declare a variable, rand, and set that to the random number: - var rand = ...Math.random...etc.
then use that to set the form value.
Hi pal,
here you are:) -
<html>
-
<head>
-
<title>xxx</title>
-
-
<script type="text/javascript">
-
function randomnumber(){
-
randomnr=[Math.floor(Math.random()*10000000000)];
-
document.reply.rand.value = randomnr;
-
document.reply.topic.value = "***RANDOM NUMBER***";
-
document.reply.action = "http://site.com/post_reply/" + randomnr;
-
}
-
</script>
-
</head>
-
<body>
-
-
<form name="reply" action="site.com/post_reply/" method="post" onsubmit="randomnumber()">
-
<input type="hidden" name="topic" value="1">
-
<input type="hidden" name="rand" value="random number">
-
<input type="hidden" name="skipVerbose" value="TRUE">
-
<input type="submit" name="submit" value="Click to send random number">
-
</form>
-
-
</body>
-
</html>

Ok, I have another form to write, and one of its features will be pop up
or drop down select-from-list stuff.
Could be done with javascript, could be done with <SELECT>
<OPTIONetc etc..
It will have to have an onselect() anyway, but apart from a better
control of appearance, what other pros and cons are there?
Coding it up looks a shade simpler in HTML rather than script, but thats

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
