    thanks to your example Yvonne, we're almost there ...

    Now, when I enter a value in the textbox of my iframe, the "parent" function is launched, it performs all he has to do ..
    but when I try to update the iframe .... lianja crash ..

    Code:
    function readText(execute)
    {
    	
    	window.alert("ReadText ");
    	window.alert(execute);
    	
    	if (execute == "X")
    	{	
    		var fileframe = executeQueryAndCreateFile("X");
    		document.getElementById("DivTabella").innerHTML ='<iframe id = "myframe" src="http:/localhost:8002/' + fileframe + '" width="100%" height="500" scrolling="yes" frameborder="0"></iframe>';	
    	}
    	else
    	{
    		var fileframe = executeQueryAndCreateFile(execute);
    		document.getElementById("DivTabella").innerHTML ='<iframe id = "myframe" src="http:/localhost:8002/' + fileframe + '" width="100%" height="500" scrolling="yes" frameborder="0"></iframe>';			
    	}
    
    };

    executeQueryAndCreateFile() function, combine the textbox and start a server procedure (lianja.evaluate()) to perform the query and prepare the new file.html.

    the second file is right, but Lianja crash..

    Hi Fabio,

    Can you reproduce that by modifying my sample?

    Regards,

    just overwrite the function:

    Code:
    	function filterComments(m_empty)
    	{
    		window.alert("in parent filterComments");
    		
    		readText();
    	
    	};
    then, click on the "Test" Button
    the file is right loaded

    type some char in the textbox under "Codice articolo", then press tab.
    the function filterComments is called and Lianja crash

    With my code, I've added a row:

    readText();

    Hi Fabio,

    Does it happen if you press the Enter/Return key instead of Tab? That's working OK for me, but not sure why.

    Regards,

    Yvonne

    If you press 2 or 3 times the "button", work fine..

    but if you type some char in the textbox and press tab, Lianja crash...

    I think the problem lies in the fact that, from inside iframe, I try to change iframe ..
    thus destroying the point at which the code is started ..
    a bit like cutting the branch on which you sit ..

    But do the thing with an external button is inelegant (and we Italians, at least in this, we are good :-) ) and I do not think even ..

    So, it would be possible to cast a function asynchronously? fire and forget ..


    thanks
    Fabio

    thanks Bary, but it does not seem to work as hoped ..

    in my inframe I've this line of HTML:
    <input width="100%" type="text" value="" id="catmercgam" onchange="window.parent.testClick()" >

    this is my RSP code:
    Code:
    	function readText()
    	{
    		window.alert("ReadText");
    		document.getElementById("DivTabella").innerHTML ='<iframe id = "myframe" src="http:/localhost:8002/_000000c40014.html?firstname=Yvonne&lastname=Milne" width="100%" height="100%" scrolling="yes" frameborder="0"></iframe>';
    	};
    	
    	function filterComments(m_empty)
    	{
    		window.alert("in parent filterComments");
    		
    		readText();
    	
    	};
    		
    	function testClick()
    	{
    		var myVar;
    		myVar = setTimeout(filterComments(), 10000);
    		
    		window.alert("Passo otre");
    	};
    but as soon as I change "cameragam", I see the message:
    window.alert ("in the parent filterComments");
    window.alert ("ReadText");
    window.alert ("Passo otre");
    then Lianja crash.
    without the 10 seconds pause.


    Instead I expected:
    window.alert ("Passo otre");
    pause 10 seconds
    window.alert ("in the parent filterComments");
    window.alert ("ReadText");
