open new window problem

Merlin

Hi there,

I have a problem with opening new windows with JS. If the webpage did not
complete loading due to any reason a click on a link which is supposed to open a
small new other window loads instead the home page. If the page completes
loading the link is working perfect.

Here is the code:
<a href="#"
onclick="open_center('/subapp_profiles/member-information.php?id=00000028',475,500);return
false;" onMouseOver="status='display profile'; return true;"
onMouseOut="status='';" title="display profile">link text</a>

Does anybody know how to fix that?

Thanx in advance,

Merlin

Define open_center() in the <head> section of your page, so it will
exist before the link is available to be clicked.

exist before the link is available to be clicked.

the open_center() funciton is inside a .js file which is loaded in the header
section of the page. So this should not be the problem. I guess it has to do
something with the way the link is coded. Any other ideas?

Thanx for any hint,

Not true. You can't be sure that a .js file is completely loaded
when the body starts to load.

Calls a function. What does the function do? Not documented.

Sets a switch
onMouseOut="status='';"

Resets a switch

title="display profile">link text</a>
I do not believe that you have provided enough information.

Could you provide a website?

Could you provide more code?

Could you write up a minimal web page with all the code and conrols
and duplicate the problem?

I did copy the code from the .js file into the header, but the same result.
If the page did not finish loading due to some images or similar a click on the
link takes the user to the home page instead of opening a new window.

Here is the code for open_center();
// opens a new window in the middle of the screen without buttons and bars
//-------------------------------------------------------------------------------------------------------
function open_center(url,width_,height_,scrollbar,toolbar,m enubar,jump) {

var H_Browserrand = 12;
var V_Browserrand = 30;
var H_Aufloesung = screen.availWidth;
var V_Aufloesung = screen.availHeight;
var H_Fenstergr = H_Aufloesung-H_Browserrand;
var V_Fenstergr = V_Aufloesung-V_Browserrand;

Fensterbreite = width_;
Fensterhoehe = height_;

H_offset= (H_Fenstergr-Fensterbreite)/2;
V_offset= (V_Fenstergr-Fensterhoehe)/2;

if (V_Fenstergr < Fensterhoehe){ // maybe the client has a smaller resulution
than the image?
V_offset = 0;
Fensterhoehe = V_Fenstergr;
vlimit= V_Fenstergr;
}
else{
vlimit = 0;
}

// if (popup) popup.close();
var popup =
window.open(url+'&vlimit='+vlimit+'#'+jump,'Detail ','width='+Fensterbreite+',height='+Fensterhoehe+' ,left='+H_offset+',top='+V_offset+',
resizable=no,scrollbars='+scrollbar+',toolbar='+to olbar+',status=no,directories=no,menubar='+menubar +',location=no')
popup.focus();
return popup;
};
//-------------------------------------------------------------------------------------------------------

The function has seven parameters but you only pass it three. Here is
a version of open_center that fills in the missing parameters.

if( typeof scrollbar == "undefined" )
{ scrollbar = "yes";}

if( typeof toolbar == "undefined" )
{ toolbar = "yes";}

if( typeof menubar == "undefined" )
{ menubar = "yes";}

if( typeof jump == "undefined" )
{ jump = " ";}

alert("scrollbar = " + scrollbar +

var H_Browserrand = 12;
var V_Browserrand = 30;
var H_Aufloesung = screen.availWidth;
var V_Aufloesung = screen.availHeight;
var H_Fenstergr = H_Aufloesung-H_Browserrand;
var V_Fenstergr = V_Aufloesung-V_Browserrand;

// You are settting glabal variables here.
Fensterbreite = width_;
Fensterhoehe = height_;

H_offset= (H_Fenstergr-Fensterbreite)/2;
V_offset= (V_Fenstergr-Fensterhoehe)/2;

// maybe the client has a smaller resulution than the image?
if (V_Fenstergr < Fensterhoehe){
V_offset = 0;
Fensterhoehe = V_Fenstergr;
vlimit= V_Fenstergr;
}
else{
vlimit = 0;
}

var popup =
window.open(url+'&vlimit='+vlimit+'#'+jump,'Detail ',

You are setting two global variables. Did you want too? See my
comment in the code.

This is a nice and informative site. It is professionally done with a
lot of thought put into it. You are best advised to contact the
programming team who wrote the site and inquire why you are
experiencing difficulties with the page.

Not true. You can't be sure that a .js file is completely loaded
when the body starts to load.

I would certainly hope you can be sure a .js file is completely loaded when the body starts to load. The only exception to this is to
explicitly use the DEFER attribute on the <SCRIPT> tag, which does allow the browser to parse/execute the JavaScript anytime it likes.

<url: http://www.w3.org/TR/html4/interact/....html#h-18.2.1 />

defer [CI]
When set, this boolean attribute provides a hint to the user agent that the script is not going to generate any document content (e.g.,
no "document.write" in javascript) and thus, the user agent can continue parsing and rendering.

Given that DEFER explicitly allows the user agent to continue parsing and rendering (the HTML), it follows that the default (non-DEFER)
alternative is that the browser stops to parse/execute the JavaScript before continuing to parse the HTML.

If you have an example of a user agent that does not load:

<script type="text/javascript" src="one.js"></script>
<script type="text/javascript" src="two.js"></script>
<script type="text/javascript" src="three.js"></script>

reproducibly sequentially, I'd be interested in knowing which one it is. I'd also recommend you contact the vendor and suggest they
correct this behavior.
