Whay not to use

JavaScript

document.GetElementById("Label1").value;

instead of

JavaScript

eval(Label1.Text);

?

In your way:

JavaScript

window.location ="result.aspx?score=" +'<%# Eval(Label1.Text)%>';

Remove: window.location ="result.aspx?score=" +'<%# Eval(Label1.Text)%>'; and add: var score = document.GetElementById("Label1").value; alert(score); See if you are able to get the label's text before redirecting. Also, are you displaying the score on page or the label is hidden?

But what is the output when you add var score = document.GetElementById("Label1").value; alert(score); in place of window.location ="result.aspx?score=" +'<%# Eval(Label1.Text)%>';?

Cto Manav Parasrampuria 4-Jan-13 9:14am

nothing....after timer expires...it display nothing....but when i use window.locatio.....it is able to redirect but value of label is not add to url..

Zafar Sultan 4-Jan-13 9:23am

So you are getting blank message in alert box? Try document.GetElementById("Label1").innerHtml or a hidden field in place of label.

Cto Manav Parasrampuria 4-Jan-13 9:33am

thank you...it will work if we use ().innerText not html
