Setting a session variable with the OnClick event.

[etjohnson81]

Anyone know how it can be done? I hate using the URL to pass information.

For example I have a table created from a query and each link is assigned a variable for the next page.

Is your intention to set the session variable w/o even navigating off the page? For something like this you would need to use javascript and a little AJAX. Googling for AJAX will bring up a ton of examples.

AJAX is probably the way to go, but I'm curious, why do you hate passing information through URL?

and do you hate POSTing information with a form?

 

[etjohnson81]

Thanks for the suggestions...the page navigates to another page and right now I am using the request.querystring. I just dont like to use it because its "dirty" looking, plus for my application it allows users to open a page without being logged in. I know, I need to add a log in check to all the pages.

SHECO... I was just thinking about a form, but Im not sure about how to use a link to submit the form, and then just use a hidden value.

Ok, well I wouldn't use the querystring, I would use the post method:

<form name="MyForm" action"bla.asp" method="post>
<input type="text" name="Username"></input>
</form>

and then Request.Form("Username")

and as for getting people to login, there are login scripts you can use. I can get one for you if you like.

And for a link to submit a form can be done. Use an onclick to a javascript function, then to submit your form.

document.[formname].submit();

I use this all the time, except I use buttons not links.

Sincerely,
Kerry

P.S. if you want working code examples of this, let me know.

That might be good. see, the thing is I would have a lot of forms. Its for a student list of up to 40 students...

 

[tiamat2012]

which were you syaing might be good? the javascript or the post method? and did you want code examples of anything?

I was saying that the post would be ok. The only thing that I am trying to figure out is how to select a certain vairable and get it to ASP.

I am kind of new with JavaScript. I am guessing that using the OnClick event with the link, I could link it to do the form.submit. How would I use JavaScript to set a form field such as a hidden?

You can use the single form for all of your rcords. Just add a small javascript function like so:

<script language="Javascript">
function submitValue(aValue){
   document.getElementById("userNameField").value = aValue;
   document.getElementById("userForm").submit();
}
</script>

Then add your form before your records:

<form method="POST" action="nextPage.asp" id="userForm">
<input type="hidden" name="username" id="userNameField" />
</form>

Then output your links so the onClick event will call the above function and pass it the value for that row:

Response.Write "<a href=""#"" title=""Some Title"" onClick=""submitValue('" & myRS("field") & "');"">Clik Here!</a>"

Remember when placing your value directly into the onClick function you will need to surround it in single quotes so it will be treated as a string by Javascript. The example above may work out of the box, but you may not need to fiddle with it, not sure. I'm still on cup #1 and I don't always function well before #3

Thanks, that was kind of what i was thinking.

I have come across another thing....

function resize_window()
{
window.sizeToContent();
window.moveto(500,500);

}

Doesnt move the window. I have it set for the body OnLoad event
