window.open() opens a window, but it vanishes. Opens 2nd time

Question

User-173333858 posted

Hi, My asp application opens another window like this:

function OpenEDEP() {            
            if ((newWindow == null) || (newWindow.closed)) {
                newWindow = window.open('./EDEP/LandingForm.aspx?LastLogin=<%=this.Last_Login%>&FullName=<%=this.FullName%>', 'EDEP_window');
                EDEPOpen = 1;
            }            
        }

Recently, on the 1st try, a new window opens for a split second and closes. Then when the button is clicked a 2nd time, it opens. I assume I need to null the newWindow value after t is closed? But what could be the reason.

Hi RDesh,

Accroding to your description,I have created a test of your codes and it works.

Could you tell us what your newWindow?Could you post your full codes to us?

Bellow is my test codes:

 <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="OpenEDEP()" />
 <script>
        function OpenEDEP() {
            var newWindow = null;
            if ((newWindow == null) || (newWindow.closed)) {
                newWindow = window.open("2170938.aspx");
                EDEPOpen = 1;
            }   
        }
    </script>

Result:
