well im mopre workign on the emphasis of things like

<input type='button' value='CENTER' name='btnUrl' onclick='wrapText(document.getElementById(&#39;inputforum&#39;),&#39;[center]&#39;,&#39;[/center]&#39;);'>

so all i really want is for it to be selected as a drop down...like you do on word ect... plus the above code does not work it just refreshes the page?

What browser are you using? I tested in IE7/FF/Chrome.

You could use the onChange event of the dropdown box to call that same function with the value that the box currently holds.

Or in your code:

function setColor(color) {
wrap(document.getElementById('txt'), "[color=" + color + "]", "[/color]");
}

im setting up some bbcode for my forum and i have run into a problem...

you see it works by adding the value in my text box but...

1. you can only select one colour
2. if you write some text then add the colour it deletes all the text??

any way around this
[CODE]
 

function setColor(color) {

                var textbox = document.getElementById('inputforum');

                textbox.value = "[color=" + color + "][/color]";

        }
 

<select id="color" onchange="setColor(this.value);">

      <option value="" selected="selected">Change Color</option>

							<option value="black">Black</option>

							<option value="red">Red</option>

							<option value="yellow">Yellow</option>

							<option value="pink">Pink</option>

							<option value="green">Green</option>

							<option value="orange">Orange</option>
