I don't know about 'CURRENT' but you have atleast 3 options:
1. if its an intranet app then just tell them they have to add the intranet server
to a trusted zone (and that the browser should allow popups
2. dump your popup info in an absolutely positioned div and make the layer
visible on top of the rest of the page (with a js link that hides the layer again)
3. use a js alert(), which you might consider ugly... BUT its modal, its not blockable
(other than if js is turned off completely!) -- a user is therefore forced to read the
alert and click OK in order to continue.
if you want to do something that is triggered by page onload() then you can use this
function to add the handler to the document.onload event without breaking any other
js code (functions) which have already been 'attached' to the onload event:
function joinFunctions()
{
var newfunc = '';
for (var c = 0;c < arguments.length;c++) {
if ( arguments[c] ) {
var func=arguments[c].toString();
newfunc+=func.substr(func.indexOf("{")-1);
}
}
return new Function(newfunc);
}
example:
window.onload = joinFunctions(
window.onload,
function() { alert('Hey User you have been assigned some new tickets!'); }
);
