How to work with Template:Mindtouch/Control template commands?

[cz6970]

Thanks for your concern.

Thats true, I got confused myself in what I want. What I actually want to do is completely different from the question I formerly asked.

This is a brief scenario:
I am in page A in my WIKI, and I asked the User to give me the URL of page B in the WIKI. What I want to do is call a template using the URL given as parameter. The problem is: the user enters the value on the client side, so I can't call the template using dekiscript.
Question: I want to call this template in javascript (JEM), and what came first in my mind is using the URL form.

If want any more details, I will be glad to share them with you.

Thanks again

The way this is typically handled is:

1. Enter user data in an <input> field
2. "Submit" the data back to the same wiki page
3. Check for the presence of the arg data in the URL. If it's there, execute the desired code.

So, for your case, let's call the argument "pageuri". Let's start with #3:

if (__request.arg.pageuri is not nil) {
    // DekiScript using pageuri, e.g.: mytemplate(pageuri);
}
else {
    // This gets executed when you first load the wiki page, *without* the argument
}

Here's a super-simple way of implementing #1 and #2:

<form>
    <input type="text" name="pageuri"/>
    <input type="submit"/>
</form>;

Of course, you're welcome to do something fancier with JEM, input validation, whatever. But this should get you started.

Great thank you neilw! You've save several hours of work

Thus, a little thing is wrong with your code, "arg" is missing an "S", the call to the parameters passed by URL is actually :
__request.args.pageuri and not __request.arg.pageuri

Please confim that i'm right

Thank you

Yes, you are correct. I frequently get that wrong. I actually thought about it while I was typing it, but convinced myself the "s" wasn't necessary. But it is.
