Changing value of a text box

NeoPuma · 10-28-2004, 01:14 AM

Hi there,
Just like this forum got, you have a button saying 'B'. when you click it, it adds the Bold tag, making all text after it bold, untill the end tag. What I want to do is simply, make a short javascript (function), which will have 2 vars, so like:

Code:

function bold(form, textbox)

I have no idea if that will work, as this is my very first thing in javascript. When the button 'B' (Form input type="Button") is pushed, I want to add [B] onto the end of document.form.textbox.value.

How would I do this?
Thanks

Try searching the forum using the keywords: insert bbCode

This question has been asked numerous times and there are quite a few examples floating about....

I think the easiest way is by changing CSS "on-the-fly"

PHP Code:


			
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>Untitled Document</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<meta http-equiv="Content-Style-Type" content="text/css">

<meta http-equiv="Content-Script-Type" content="text/javascript">

<script language="JavaScript" type="text/JavaScript">

function boldT(f,t){

f.elements[t].style.fontWeight='bold';

}

</script>

</head>

<body>

<form>

<input name="textbox" type="text">

  <input type="button" onclick="boldT(this.form,'textbox')" value="Bold">

</form>

</body>

</html>
