Question

Pop-up script variables

Asked by: guy4graphics

I added the l and t variables to make the pop-up centered on any resolution screen. But i think my syntax is wrong in the last few lines as the pop-up no longer works.

function popUp(URL) {
day = new Date();
id = day.getTime();

var t = (screen.height-height)/2;
var l = (screen.width-width)/2;

eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=342,height=282',left = '+l+',top = '+t+');");
}

I think you're close.  I just see a few quote-marks that're a bit confused.  Try:

eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=342,height=282,left=" + l + ",top=" + t + "');");

that still is not working for me... here is how it looked originally before I added the variables.

<SCRIPT LANGUAGE="JavaScript">
<!-- Idea by:  Nic Wolfe (**adminedit.com**) -->
<!-- Web URL:  http://fineline.xs.mw -->

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
function popUp(URL) {
day = new Date();
id = day.getTime();
eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=342,height=282,left = 669,top = 384');");
}
// End -->
</script>

So you should be able to simply replace
    669
with
    " + l + "
and to replace
    384
with
    " + t + "

It might also not be a bad idea to build this as a string separately and then pass it into the eval function.  This would also allow you to look at it directly, such as in an alert statement, and see it if looks right.  So, for example, instead of:

    eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=342,height=282,left=" + l + ",top=" + t + "');");

do something like:

    var evalStr = "page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=342,height=282,left=" + l + ",top=" + t + "');"
    alert(evalStr);  // temporary, for testing
    eval(evalStr);
