[Xerte] Re: Reading POST parameters from web page in RLO

[Kemp Johnathan]

I am trying to do something very similar to Ron - I want to pass a pageID
in the url and trap it in xerte so that a url can be used to not just open
a Xerte project but also to go to a specific page in that project.

I have the function sorted to trap the parameters from the url, but I can't
get the passing of data back to Xerte to work.

I tried your suggestion and also found a suggested form from Julian, posted
in August 2007

in rloObject.js I have

function myFunction(arg){
alert('I am a function and my argument is ' + arg);
return arg.toUpperCase();
}

simple enough function as a test.

Then in my Xerte script on the test title page I have

mydata = getURL("javascript:myFunction('a test');","");

if (mydata != undefined){
titleStr = mydata;
} else {
titleStr = "data not received";
}

I publish the project and then test it in Firefox and Opera

In both Opera and Firefox the alert displays.
In Opera the title of the page displays as "data not received".
In Firefox the xerte display is displayed without anything in the page
title whilst the alert is displayed. When the alert is clicked, very
briefly the Xerte page displays with the title as "data not received" then
the whole screen is replaced with a white screen with the text "A TEST"
displayed. So this shows the function is returning something, but Xerte is
not capturing it.

What am I doing wrong here?

Kind regards

Johnathan
