Getting list of CSS properties

Hi Is there a way to check what CSS properties are applied to an HTML Element. I dont want any browser plugin. Using javascript, I want to get a list of all CSS 开发者_JAVA百科properties set on an html element. If thats not possible, I can always write 100 lines of code and checking the value like if($("div").css("background-color").length > 0){}, for each and every css property.

As mentioned, I also recommend you using inspecting tools as Firebug, Webkit Inspector and Dragonfly.

But if you need just a quick check on CSS properties, you can create a quick script. There are some DOM methods and properties that becomes handy, like element.currentStyle and element.getComputedStyle().

Depending on your browser, you can use the following plugins or tools (linked where necessary):

• Firefox - Firebug (download the addon, restart and press F12 to open)
• Google Chrome, Safari - Webkit Inspector (CTRL+SHIFT+I to bring it up)
• Opera - Dragonfly (CTRL+SHIFT+I)
• Internet Explorer 5.5-7 - IE Developer Toolbar (press the icon near your address bar)
• Internet Explorer 8+ - IE Developer Tools (press F12 to open)

You might need to be a bit more elaborate. But for now Firebug seems to fit your description.

Using javascript :

Object.keys(document.getElementsByTagName('HTML')[0].style).join(',')

This instruction will list all CSS properties :

To check if a css property is applied : Use the following function :

String.prototype.isCssProp=function(hTMLElement){
  if(hTMLElement instanceof HTMLElement){
        var all=','+Object.keys(hTMLElement.style).join(',')+',';
          if(all.indexOf(','+this+',')===-1){
              return false;
          }else{
               return true
           }
    }else{
       return false;
    }

}

And then , use it :

var hTMLELement=document.getElementById('myid');
"color".isCssProp(hTMLELement);
"background-color".isCssProp(hTMLELement);
