[Xerte] Calling a function

Tue Aug 28 09:15:22 BST 2007

It works for me. There are errors in your code:

You have a nested string, which you are surrounding with single quotes '
when the entire string is surrounded with single quotes.

getURL('javascript:test("param");', ''); //this works and calls the
function 'test' defined in rloObject.js. Note the quotes.

Also, getURL takes two parameters, the second needs to be an empty
string.

I'm having trouble with the recent code.  I publish my piece and insert
the following at the bottom of rloObject.js:

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

The piece contains a button that, when clicked, runs this code:

getURL('javascript:myFunction('a test');');

I run the piece and click the button.  The result: a new IE window opens
for about 1/2 second and then a message box appears:  Internet Explorer
cannot download.  Unspecified error.

I've tried several variations of the code but still get the same
message.

I can place a simple function in the html page and call it from the same
page with this code:

<html>
<head>

<script type="text/javascript">
function myfunction()
{
alert("HELLO")
}
</script>

</head>
<body>

<form>
<input type="button"
onclick="myfunction()"
value="Call function">
</form>

<p>By pressing the button, a function will be called. The function will
alert a message.</p>

</body>
</html>

But I'm unable to call a function in rloObject.js.  What am I missing?

Thanks.

Jim

You need to modify rloObject.js and add your functions to the bottom of
it like this:

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

Then you can call the function from Xerte using getURL:

getURL('javascript:myFunction('a test');');

I am trying to minimize the active window from a button.  Although
javascript will not minimize the window, there is a workaround.  The
following code moves the current window off screen.

<script language="javascript">
show=1
function minimize(){
  moveBy(2000,2000)
  show=0
}
function reshow(){
  if(show==0){
    moveBy(-2000,-2000)
    show=1
  }
}
</script>

I plan to add the code onfocus=reshow() to the body tag.  When the focus
is passed back to the window, the code in the body tag will return the
screen to it's original location.

I also need to add code so the button calls the function:  minimize().
I need help here.  How can I call this function in Xerte?
