Text selection disable javascript & Opera Browser

While the script works fine on all browsers except Opera Browser. Input fields and drop down menu becomes unclickable, how to fix it?

My example page:

http://www.aymavisi.org/makale/Evlil...20Gibran).html

Head:

Code:

---

<script type="text/javascript">
function disableSelection(target){
if (typeof target.onselectstart!="undefined") //IE route
        target.onselectstart=function(){return false}
else if (typeof target.style.MozUserSelect!="undefined") //Firefox route
        target.style.MozUserSelect="none"
else //All other route (ie: Opera)
        target.onmousedown=function(){return false}
target.style.cursor = "default"
}
</script>

---

Body:

Code:

---

<script type="text/javascript">
disableSelection(document.body)
</script>

<script type="text/javascript">
var somediv=document.getElementById("layer1")
disableSelection(somediv)
</script>

---

P.S
You can choose install Opera as portable in installation options.

First of all this is sort of a silly thing to do. If the user wants the text, they can use their browser's "View Source" and copy it from there or disable javascript and select the text in the normal fashion.

But in Opera you can try:

Code:

---

<script type="text/javascript">
function disableSelection(target){
if (typeof target.onselectstart!="undefined") //IE route
        target.onselectstart=function(){return false}
else if (typeof target.style.MozUserSelect!="undefined") //Firefox route
        target.style.MozUserSelect="none"
else //All other route (ie: Opera)
        target.onmousedown=function(e){if(e && e.target && e.target.tagName){if(/^(input|select)$/i.test(e.target.tagName)){return true;}}return false;}
target.style.cursor = "default"
}
</script>

---

The browser cache may need to be cleared and/or the page refreshed to see changes.

No guarantee. But it might work. Otherwise, just let Opera users slide:

Code:

---

<script type="text/javascript">
function disableSelection(target){
if(window.opera){return;}
if (typeof target.onselectstart!="undefined") //IE route
        target.onselectstart=function(){return false}
else if (typeof target.style.MozUserSelect!="undefined") //Firefox route
        target.style.MozUserSelect="none"
else //All other route (ie: Opera)
        target.onmousedown=function(){return false}
target.style.cursor = "default"
}

Thank you very much jscheuer1 The script worked great. I know it but it's better than nothing. Also my site's content has became less stolen since I add this script.

You're welcome. I'm wondering though, how can you tell? How can you know your site is less stolen?

I just copy a line from a page put it around quotes and see if any other site has the same content. Before this script several forums steal my content daily but now most of them give up.

Ah, I see. I guess this is a case where making it a little harder does make a difference. Though this is what's known as anecdotal evidence. In order to really know, you would have to do a quote from each page each day and tally up the results. At the very least you would have to use the same quote each day, but that's less scientific.

I just noticed though that on the page you linked to in your first post that you haven't made the change yet. In Opera the drop down menu and the inputs are still disabled. But I can select the text! If I start my selection a little above and to the left of the poem I can select all or nearly all of it.

It's because that element is the HTML element (also known as the document), and is not included in your scripts. That may also be because the page is in quirks mode, it should be the body there I think and would be covered. Either way, the way to fix that is (remove the highlighted):

Code:

---

<script type="text/javascript">
disableSelection(document.body)
</script>

---

So you have:

Code:

---

<script type="text/javascript">
disableSelection(document)
</script>

---

And now I'm wondering, when they do quote you, do they quote the entire poem, verse or whatever it is? If not, it's really a form of advertising. People will see the partial quote and search for the full text.

But if they're generally grabbing the entire poem you are probably better off doing what you're doing. You could make a hotlink available for each page though. That's just a link to the page itself. I think most browsers will automatically make such a link if an empty href is given:

Code:

---

<a href="">Hot Link</a>

---

Or you can just put the page's address there for the href. Using javascript:

Code:

---

<script type="text/javascript">document.write('<a href="' + location.href + '">Hot Link To This Page</a>');</script>

---

Just put that where you want the hot link to be.

People who want to quote you but can't, can use the hotlink in their post. If they do it will raise your site's ranking in the search engines.

Just to let you know, there is actually a way to do this in css -

Code:

---

        -webkit-user-select: none;
        -khtml-user-select: none;
        -moz-user-select: none;
        -o-user-select: none;
        user-select: none;

However, it doesn't seem to work in Opera (and I haven't tested it in every browser)... Maybe Opera just doesn't support it...
