    Disable right-click

    Hi. What's the best way to display an image, disabling the user's ability
    to right-click on it?

    I believe you have to use <body oncontextmenu=" return false">. Would the
    following work?

    var x = "<head><\/head><body oncontextmenu=" return false"><img
    src='temp.jpg' border=0><\/body>"

    top.document.op en()
    top.document.wr ite(x)
    top.document.cl ose()

    Since this is a frameless site, I don't think this would work, at least
    would never get to the close()...Denni s

      In general, no. (Not even disabling the effect of right-clicking :).

      Some browsers will allow it, but not all, and it is trivial to circumvent.

      That will, in some browsers, disable the context menu for the entire
      page. Highly annoying a reason enough to leave the page.

      You can put it on the image itself instead:
      <img oncontextmenu=" return false;" src="..." alt="...">
      (remember, the "alt" tag is *required* for valid HTML).

      Have you tried? What was the result?

              Strangely enough, it did work. Use an <a href="temp.jpg"
              onclick=Display (this)>, which does:

              function Display(obj) {
              var img = obj.getAttribut e("href")
              var x = '<head><\/head><body oncontextmenu=" return false"><img alt=""
              src="'+img+'" border="0"><\/body>'
              top.document.op en()
              top.document.wr ite(x)
              top.document.cl ose()
              return false

              Of course this doesn't disable the file "Save As" for the web page. IE
              saved the "Display()" web page, but not the image itself. Is that because
              oncontent is disabled?

              As for why I need to do it, the client requested it...Dennis

                  Demonstrate to your client how easy it is to left click on an image and drag
                  it to your pictures folder.

                      Re: Disable right-click

                      Here's How I do it.

                      The code below in in a file called 'DisableRClick. js'
                      Every page has :
                      <script language="Javas cript" type="text/javascript"
                      src"include/disableRClick.j s"></script>
                      in its header

                      DisableRClick.j s contains the code:

                      document.oncont extmenu = function(){retu rn false}
                      if(document.lay ers) {
                      window.captureE vents(Event.MOU SEDOWN);
                      window.onmoused own = function(e){
                      if(e.target==do cument)return false;
                      }
                      }
                      else {
                      document.onmous edown = function(){retu rn false}
                      }

                      This works in IE and Mozilla - havn't test with Netscape yet.

                          No it doesn't, you just *think* it "works" there.

                              You might want to mention to your client that disabling the right click
                              menu violates the accessibility rules.
                              Disabled people use that menu to navigate. Some of us who aren't
                              disabled use it, too.
                              Disabling it is irritating, to say the least.

                              And any idiot can drag and drop an image from IE.
                              Any moron with an image editor can screen cap the page and edit the
                              image. Slightly more IQ points and they can remove your digital
                              watermark.
                              Anyone with a moderate level of intelligence can read the source, get
                              the link, and view it as an image by typing it in the address bar.

                              Anyone can disable javascript and bypass anything you do with it.

                              Sometimes, we need to save clients from themselves. heh

                                      No. You use that worthless, non-working garbage to attempt to disable
                                      it. It does *not* disable the right click.

                                      That does nothing in my browser. But even in IE6, I don't even need to
                                      use my mouse to get anything in the page. File>Save As and there it is.
                                      Every bit of it.
