Question

i wish to add a further action to the script to change the css for a class

document.write( 'DIV STYLE='display;none;); />' ) } was my initial idea but it doest seem to work so using

    if (location.href.indexOf( "/smispage""/tpfpage""/client_images_new""/client_images_list" ) > -1) {
document.write( '<base target="_blank" />' );
     }

and adding to it with

    if (location.href.indexOf( "/smispage""/tpfpage""/client_images_new""/client_images_list" ) > -1) {
document.write( '<base target="_blank" />' ); document.write( 'DIV STYLE='display;none;); />' ) 
    }

the body is

     <div class="headerlogo"> Serious Photography </div>
     <div> Serious Photography 2 </div>

Answer 1

This is kind of a hard question to follow, but if you want to check for what page you are on, you can use

window.location.href 

A conditional check to match the strings could then decide whether you want to add the new style. I’d change the class to an ID.

then you can do

document.getElementById('headerlogo').style.display = 'none';

Personally, I’d use SIZZLE or jQuery to make the selectors easier.

$('.headerlogo').css('display', 'none');
