Hello experts,

the below script does not work.
what i am trying to do is to get the first image height so i can set the image container div height. all the images having the same height and width but because i resize it to 80% i need to know the height so i can set the container.

$(document).on('pageinit', function() {
	var houseContainerHeight = $('#img01').height();
	alert (houseContainerHeight);
		
	$('#img02, #img03').hide();
	
	$('#img01Btn').click (function() {
		$('#house-container img').hide();
		$('#img01').show(500);		
	});
	$('#img02Btn').click (function() {
		$('#house-container img').hide();
		$('#img02').show(500);		
	});
	$('#img03Btn').click (function() {
		$('#house-container img').hide();
		$('#img03').show(500);		
	});	
});

<div id="house-container" align="center" style="margin:auto; display:block; overflow:hidden'">
<img id="img01" src="images/ansichten/front.jpg" alt="" style="width:80%; ">
<img id="img02" src="images/ansichten/back.jpg" alt="" style="width:80%;">
<img id="img03" src="images/ansichten/garden.jpg" alt="" style="width:80%;">
</div>

Do like this...

$(document).on("pageshow", function() {
	var houseContainerHeight = $('#img01').height();
	alert (houseContainerHeight);
		
	$('#img02, #img03').hide();
	
	$('#img01Btn').click (function() {
		$('#house-container img').hide();
		$('#img01').show(500);		
	});
	$('#img02Btn').click (function() {
		$('#house-container img').hide();
		$('#img02').show(500);		
	});
	$('#img03Btn').click (function() {
		$('#house-container img').hide();
		$('#img03').show(500);		
	});	
});

Hi sonawanekiran,

i am still getting "0" in the alert. for some reason i do not understand why!?
the script in currently inside the page at the bottom before the closing of the body and the html maybe that's the reason? should it be placed somewhere else?
