Below is the code
from a plugin for Joomla. It works on it's own and it's purpose is to detect external links on the page and force them into new browser windows using _blank.
I've tried for about an hour (I don't know javascript well) but I can't seem to figure out how to get an onclick function working.
End result, I want to add to this script the ability of a confirmation dialog, shown in the 2nd code section.
An external link, when clicked, will pop up the confirmation dialog, and if it says yes, they will be able to get to the external URL, opening in a new
window. Otherwise, it cancels, and does nothing.
When I create a link with onclick="return ExitNotice(this.href);" within it it works perfectly, but since my website has multiple people submitting input, I'd like the confirmation box global.
this.blankwin = function(){
var hostname =
window.location.hostname;
hostname = hostname.replace("www.","").toLowerCase();
var a = document.getElementsByTagName("a");
this.check = function(obj){
var href = obj.href.toLowerCase();
return (href.indexOf("http://")!=-1 && href.indexOf(hostname)==-1) ? true : false;
};
this.set = function(obj){
obj.target = "_blank";
obj.className = "blank";
};
for (var i=0;i<a.length;i++){
if(check(a[i])) set(a[i]);
};
};
this.addEvent = function(obj,type,fn){
if(obj.attachEvent){
obj['e'+type+fn] = fn;
obj[type+fn] = function(){obj['e'+type+fn](window.event );}
obj.attachEvent('on'+type, obj[type+fn]);
} else {
obj.addEventListener(type,fn,false);
};
};
addEvent(window,"load",blankwin);
Second Part
/* ----------
OnClick External Link Notice
---------- */
function ExitNotice(link,site,ltext) {
if(confirm("-----------------------------------------------------------------------\n\n" +
"You're leaving the HelpingTeens.org website. HelpingTeens.org\ndoes not " +
"control this site and its privacy policies may differ\nfrom our own. " +
"Thank you for using our site.\n\nYou will now access the following link:\n" +
"\n" + link + "\n\nPress \'OK\' to proceed, or press \'Cancel\' to remain here." +
"\n\n-----------------------------------------------------------------------"))
{
return true;
}
history.go(0);
return false;
}
A) Can anyone help me fix this problem?
or B) Is there a better solution?
