No select text script

[jscheuer1]

No select text script has a bug in Mozilla. Because the array of tag names to be excluded in NS6+ (Mozilla) is joined into a string before the target tags are tested against it, unintended tags get excluded from the no select text treatment. Here is the array from the demo:

var omitformtags=["input", "textarea", "select"]

Here is the string that results from the join method used:

input|textarea|select

Here is the test against that string:

if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)

Basically, if the tag's lower case name is in that string, it is exempt from the no select treatment. This will include <input>, <textarea> and <select> to be sure but, also <p> and <a> tags. I've come up with a simple remedy which uses the array as is, without joining it to a string. I've also got a method to exclude these same areas under IE6 but, it co-opts the onmouseup event for those elements. Not such a big sacrifice as other events can be used in most cases to work around that. Here is the code:

<script type="text/javascript">

/***********************************************

//form tags to omit:
var omitformtags=["input", "textarea", "select"]

function disableselect(e){
for (i = 0; i < omitformtags.length; i++)
if (omitformtags[i]==(e.target.tagName.toLowerCase()))
return;
return false
}

function reEnable(){
return true
}

function noSelect(){
if (typeof document.onselectstart!="undefined"){
document.onselectstart=new Function ("return false")
if (document.getElementsByTagName){
tags=document.getElementsByTagName('*')
for (j = 0; j < tags.length; j++){
for (i = 0; i < omitformtags.length; i++)
if (tags[j].tagName.toLowerCase()==omitformtags[i]){
tags[j].onselectstart=function(){
document.onselectstart=new Function ('return true')
}
tags[j].onmouseup=function(){
document.onselectstart=new Function ('return false')
}
}
}
}
}
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
}

window.onload=noSelect;
</script>

Hopefully this can be simplified and/or made to append to the onmouseup event in IE for protected tags, rather than co-opting it.

OK, I got IE to append to the onmouseup event (if any) in form tags, rather than co-opt it. Here's the latest:

<script type="text/javascript">

return;
return false
}

function reEnable(){
return true
}

function noSelect(){
if (typeof document.onselectstart!="undefined"){
document.onselectstart=new Function ("return false")
if (document.getElementsByTagName){
tags=document.getElementsByTagName('*')
for (j = 0; j < tags.length; j++){
for (i = 0; i < omitformtags.length; i++)
if (tags[j].tagName.toLowerCase()==omitformtags[i]){
tags[j].onselectstart=function(){
document.onselectstart=new Function ('return true')
}
if (tags[j].onmouseup!==null){
var mUp=tags[j].onmouseup.toString()
mUp='document.onselectstart=new Function (\'return false\');\n'+mUp.substr(mUp.indexOf('{')+2,mUp.lastIndexOf('}')-mUp.indexOf('{')-3);
tags[j].onmouseup=new Function(mUp);
}
else{
tags[j].onmouseup=function(){
document.onselectstart=new Function ('return false')
}
}
}
}
}
}
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
}

window.onload=noSelect;
</script>

Hello

After finding this thread via a Google search - and then finding the script doesn't work properly, I wrote my own.

Anyway, I thought others that also find this thread might find my version useful, so here's a linky:

i didnt try your script bandit but jscheuer1 dude your a true genius, that script is working perfect for me in Firefox 1.5.0.7... i didnt understand a word you said but if it works with IE as well then I think it should replace http://dynamicdrive.com/dynamicindex9/noselect.htm
