javascript confirmation with 2 levels

Copy linkTweet thisAlerts:
Oct 12.2005

Hi,

I’m new to javascript and writinig a function for an ASP.NET C# webform.
I have a delete command button on the form.
When the user clicks on the form following logic occurs:

if labelcontrol1.value has a value then

var result = confirm(“Are you sure you want to delete”);

if(result)
{
fire the C# server side click event code which will delete record.
}
else
{
do nothing.
}

else

alert (Please choose a record.”) “Can’t delete unless a record is chosen.”

end if

sorry, i don’t know the syntax yet of javascript.

the main problem is how to get the server side click event to fire if the Okay button is choosen in the javascript confirmation window?

humbly requesting help.

thanks

@haggisnsauthorOct 13.2005 — Hi,

thanks for response.

I am using ASP.NET web control button.

I am using the add.attributes method to add the javascript from a

.js file.

When I run the script it continues on to the click event in the code behind page for the button. I want to stop it from going to the code behind page.

Should I have an invisible checkbox to hold the value of true/false and then read it from the code behind page?

thanks

forget that idea,

the whole point is not to run server side code unless I truly want to

delete a record.

Success!
