Default How do I change the .body background color with Javascript?

As per title. I would like to add an option to let users change the style's .body background color in their usercp. And it should be saved in their options, so they see that color until they change it again.

Hi,

i've been looking at something like this myself, here is a very basic example

1st you need to save this code as a Javascript so copy it to your notepad and save it as "Backcolor.js"

Code:
function change_it() {
	
  if (document.getElementById && document.createTextNode) {
	  
    var new_color = "";
    var color_sel = document.getElementById("change_bg").value;
	color_sel *= 1;
    
	switch (color_sel) {
      case 0 : window.alert("Please select a color."); return false;
	  case 1 : new_color = "#FFFF00"; break;
      case 2 : new_color = "#3333FF"; break; 
	  case 3 : new_color = "#009900"; break;
	}
    
	document.body.style.backgroundColor= new_color;
    return false;
	
  }
 
}
then you upload the backcolor.js file to same directory as the Web page on which you will use the script (ideally your Forum Root)

Then enter the code below, between the <body> and </body> tags where you want the select box and button to appear, ideally in the footer or header templates

Code:
<form action="#" onsubmit="return change_it();">
<select name="change_bg" id="change_bg">
<option selected="selected" value="0">Select Background</option>
<option value="1">Yellow</option>
<option value="2">Blue</option>
<option value="3">Green</option>
</select> 
<input type="submit" value="Change Color" />
</form>
<script type="text/javascript" src="backcolor.js"></script>
What that will do is give your users a dropdown box with a Change Color button ( for the english spelling please change the above code here <input type="submit" value="Change Color" />

i've done this very basic, but you can change the colors in the backcolor.js file just change the case 1, 2 and 3 options with a new hex color #FFFFFF

You can get a nice selection of hexcolors here http://www.december.com/html/spec/colorsafe.html

This is what you get, Mind you it won't work well on my forum as its fluid, but it'll work well with fixed forums





Remember you can change these colors, I've just done 3 as an example, But you can add as many as you want and with millions of combinations by using a color Hex chart.

Have Fun
