window.open window not displaying

Copy linkTweet thisAlerts:
Aug 28.2020

I’m executing a function on onclientclick.

var newwindow;
function GetUrlPage() {

var pplid = document.getElementById(‘<%= tbPersonId.ClientID %>’).value;

newwindow = window.open(‘MXUrl.aspx?PersonId=’ + pplid, null,
“Width=475px, Height=500px; top=42px; scrollbars=1; toolbar=0; titlebar=0; menubar=0; statusBlush | :O ;”);

Nothing happens. If I add an alert(“some message”); after the window.open everything works great.
I can only assume it is just blowing thru the code but I don’t know how to make it wait.

Don’t do much in javascript so am really at a loss. Really appreciate any help you can give me.

@cootheadAug 28.2020 — Hi there rick0127,

I believe that most browsers block pop-up windows by default.

@rick0127authorAug 28.2020 —  Thanks for the reply. I have other pop-ups that are working fine.

I changed from window.open to Response.Redirect which works. Don't know why, not what I want to do but the only solution I could find. I would really like to know why.


thanks

I verified this in my browser (Opera).

@VITSUSAAug 29.2020 — @rick0127#1622703 I agree with coothead, most browsers block pop-up windows by default, otherwise, you can :)

@rick0127authorAug 29.2020 — Sounds logical. Do you guys have any idea on why it works correctly when I add an 'alert' after the window,open? I don't understand how that changes things.

yes

when things work after an alert it is a classic

symptom of a timing problem

set a time out before trying to access the new window

or even much better have a javascript to call from the

new window back to the original window

make this call from the last line of the new window

call the function that access the new window

just a guess but it is a problem I have solved

in the past with this method

@rick0127authorAug 30.2020 — A timing problem really make sense to me but I not sure if I understand how to "have a javascript to call from the

new window back to the original window". Like I said early I really don't do much in Javascript so it's probably just a lack of knowledge on my part.

Success!
