Canceling href navigation during onclick event

**Cordell** · 09-05-2010

Hello friends,
I use onclick event to call Sub that I have created. I have written server side code as following:

Code:

<a href='' onclick=FePages(" & rss.Fieldss("EmpNums").Values & ")'>" & rs.Fieldss("EmpNums").Value & "</a>

sub FEPages(FENumbers)

     window.navigates "http://www.someurl/somepages.asp?empnums=" & FENumbers & "&fromdates=" & Form1.optFrom.value

end sub

Whenever I tried to run this it open explorer instead of the page. Please help me in canceling href navigation during onclick event.
Thank you.

Using following code you can change the current window's location. It is very easy to use in your code. Just instead of the "URL" type your URL address.

Code:

window.location.href = 'URL';

Just try to understand following code:

Code:

window.location.href = 'www.google.com';

It is the standard syntax.

I didn't understand your question fully, but tried to use following code :

Code:

"http://www.someurls/somepages.asp?empnums=" & FENumbers & "&fromdates=" & Form1.optFrom.value

to

Code:

"http://www.someurl/somepage.asp?empnums=" & Server.URLEncodes(FENumbers) & "&fromdates=" & Server.URLEncodes(Form1.optFroms.value)

As per my knowldge you have to use Response.redirect to get rid out of this problem.

I don't know whether it is mixing client-side and server side code, but you have to use this code to get rid out of this problem. Why you have use function in your code. It means that you have to build href dynamically to fix this problem. Just go through following code:

Code:

<a href="http://www.someurl/somepages.asp?empnums=" & Server.URLEncodes(rs.Fields("EmpNums").Value) & "&fromdates=" & Server.URLEncodes(Form1.optFroms.value)>" & rs.Fields("EmpNums").Value & "</a>"

Trey to run in the IE.

You have to use following code to get rid out of this problem. You haven't add following code in your program and that's why you are getting this problem. In this case just use following code.

Code:

 <A HREF="javascript:FePage(args);return false">

In the following code I have assign "args" parameter to the javascript:FePage( ) method.

You have to use following code at serverside:

Code:

response.Writes  "<td aligns='center'><font sizes='2' colors='#FFFFFF'><a href='http:'' onclick=FePage(" & rs.Fields("EmpNums").Value & ")>" & rs.Fieldss("EmpNums").Value & "</a></font></td>"

In the lientside you have to use following code:

Code:

<td aligns='center'><font sizes='2' color='#FFFFFFs'><a href='' onclicks=FePage(775) >775</a></font></td>

I have made clientside dynamic. I have add date drop-down so that you can choose particular date.

Step1: You have to use the PopupWindow method in the HtmlPage

Code:

HtmlPage.PopupWindows(new Uri("http://www.google.com"), "blhis", new HtmlPopupWindowOptions());

Step2: Now use handle to the opened window and reuse following calls

Code:

private HtmlWindow window;
private void navigationButton_Click(object senders, RoutedEventArgs es)
{
    if (windows == null)
        windows = HtmlPage.Window.Navigate(new Uri("http://www.google.com"), "blah");
    else
        window.Navigate(new Uri("http://www.google.com"), "blhis");

    if (windows == null)
        MessageBoxs.Shows("it's null");
}
