some javascript/php questions (too simple I can't see it?)

tribe

Hi gang! Here's the first one.

I'm doing some basic cookie stuff and everything works fine in standard html. When I put this line in the body tag:

onLoad=\"getValues();\" onUnload=\"setValues();\"
of my php page it causes javascript errors. Any reason why?

Second one:

I would love to make some formst with the buttons in this php board. The ones where you click on B to produce bold text, and I for italacs etc...that would be great! Does anyone know how to do that, or point me to a place where the scripts are written so I can figure it out myself?

Thanks in advance.

What is the javascript error? Undefined? Syntax? ???

Well you need to use the prompt() function to get the text.
Then add the tag to the block of text.
Grab the text from the textarea,
find the insert point,
then
newText = [All the text before the insert] + " " + taggedText + " " + [All the text after the insert]

Goto Javascriptsource.com for help. Note: you might need multiple versions for various browsers.

heres how to do the formatting: just add more switches

<script>
function format(type)
{
	switch(type)
	{
		case 'b':
			txt=prompt("Enter text to be bolded","");
			txt = "<b>" + txt + "</b>";
			break;
		case 'i':
			txt=prompt("Enter text to be italicized","");
			txt = "<i>" + txt + "</i>";
			break;
		default:
			txt="Error with Type: " +type;
	}
	a.b.value+=txt;
}

</script>
<body>
<form name="a">
<input type=button onClick="format('b');" value="B">
<input type=button onClick="format('i');" value="I"><br>
<textarea name="b"></textarea>

hey gang, thanks a lot for the response!!!!

My problem before was a silly one. I forgot to name the form correctly...stupid.

Thanks for the help on the text changes. I'm gonna try your suggestions out!!!

I have another question. If I'm trying to add the [url]http://[/url] I used this switch, but I can't figure out how to make the " go in front of the [url]http://[/url] and it's end.

case 'url':
txt=prompt("Enter the web address","http://");
txt = "<a href=" + "'" + txt + "'" + "</a>";
break;

		case 'u':
		t1=prompt("Enter Description (optional)","");
		t2=prompt("Enter Link Address","http://");
		txt="<a href=\"" +t2+ "\">";
		// conditionals rock! =) //
		txt+=((t1)?t1:t2);
		txt+="</a>";
		break;

if no description, it puts the link add(t2) as the desc.. exactly like putting a link in a post 🙂

Broken, where is the best place to learn this stuff? You've given me exactly what I've been looking for, I can't find this anywhere on the net.

How about books on javascript? (Sorry guys, I know this is a PHP forum, I'll go away after this.)

This has been great! Great!!!

best place to learn this kinda stuff? hmm.. well, i learned JS in school last year,a nd since then ive learned to hate it with a passion (and it hates me too). but basically to learn things just sit around and think of something stupid to make and practice. Other than that, http://javascript.internet.com has thousands of little scripts to help you do nearly anything(or see how its done)

with books:
JavaScript (for the world wide web) by visual quickstart is a good book bc its more of a reference than anything else 🙂

if you need anymore help, ill try and help u

just throw in a browser check, and a switch to make the syntax different, im not sure how to do it- but it shouldnt be that hard

oh, if all else fails: view the source to this page and see how they do it 🙂 (if its linked to an external .js file, just put the js file name in the browser to dl it)
