As you can see here the google map in the first jQuery ui tab loads correctly but the same map in second / third etc tabs does not load properly or loads off centre.

As mentioned here the problem is that "Any component that requires some dimensional computation for its initialization won't work in a hidden tab, because the tab panel itself is hidden via display: none so that any elements inside won't report their actual width and height (0 in most browsers)."

I have read for example here that the problem is that the map loads after the jQuery UI tabs and so I need a jQuery snippet in my (Drupal 7) theme's behaviors.js to to make the map load before the jQuery UI tabs.

(Please note that the alternative solution of applying CSS to .ui-tabs .ui-tabs-hide will not work for me because it causes problems elsewhere.)

Can anyone please tell me the code I need for my-theme.behaviors.js ?

my template.php =

<?php
function whitecross_160614_preprocess_html(&$variables){
// some comment here
    drupal_add_library('system', 'ui.tabs');
    drupal_add_js('jQuery(document).ready(function(){
                jQuery("#tabs-x, #tabs-y").tabs({event: "click"});
                jQuery("#tabs-x, #tabs-y").tabs().addClass("ui-tabs-vertical ui-helper-clearfix");
                jQuery("#tabs-x li, #tabs-y li").removeClass("ui-corner-top").addClass("ui-corner-left");
            });',
        'inline');
}

HTML =

<div id="jqueryui-tabs-wrapper">
<div id="tabs-x">
<div id="tab-list">
<ul>
<li><a href="#tabs-1">Map 1</a></li>
<li><a href="#tabs-2">Map 2</a></li>

  • what about simply making the opacity of the 2nd and 3rd 0 until initialization is complete. they would still display, just not be visible. – Geoff Jun 27 '14 at 22:30
  • @ Geoff - thanks for your reply - do you mean .ui-tabs .ui-tabs-hide {display:block; opacity:0;} - if so one problem is that the tabs will stack vertically so causing a big empty space below ie where the tabs are there but invisible. – Juc1 Jun 28 '14 at 13:04
  • opacity shouldn't affect position. and I would first try on the iframe itself. – Geoff Jun 28 '14 at 13:48

Further to the comments, here is a jsfiddle of what I was talking about. This is a quick example, but should be easily adapted to your own code. I altered the dimensions on the maps to show the change

CSS:

#toolbar
{
    width:100%;
    height:20px;
    background:#000;
}

#toolbar li
{
    display:inline-block;
    min-width:100px;
    background:#fff;
    color:#000;
    border:1px solid #ffff00;
    cursor:pointer;
}

#maps
{
    position:relative;
    width:800px;
    height:600px;
    overflow:hidden;
}

#maps #tabs-1,
#maps #tabs-2,
#maps #tabs-3
{
    position:absolute;
    top:0;
    left:0;
    width:800px;
    height:600px;
}

#maps #tabs-2,
#maps #tabs-3
{
    opacity:0;
}

HTML:

    <div id="toolbar">
        <li id="toolbar_tabs1">Map 1</li>
        <li id="toolbar_tabs2">Map 2</li>
        <li id="toolbar_tabs3">Map 3</li>
    </div>

    <div id="maps">
        <div id="tabs-1">
<iframe src="https://www.google.com/maps/embed?pb=!1m14!1m8!1m3!1d2483.645966939501!2d-0.14189000000000002!3d51.501364!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x0%3A0xa26abf514d902a7!2sBuckingham+Palace!5e0!3m2!1sen!2suk!4v1403805298071" width="800" height="600" frameborder="0" style="border:0"></iframe>

<div id="tabs-2">

</div>

JS:

jQuery('#toolbar_tabs1').click(function(){
    jQuery('#tabs-1').animate({'opacity':1}, 200);
    jQuery('#tabs-2').animate({'opacity':0}, 200);
    jQuery('#tabs-3').animate({'opacity':0}, 200);
});

jQuery('#toolbar_tabs2').click(function(){
    jQuery('#tabs-1').animate({'opacity':0}, 200);
    jQuery('#tabs-2').animate({'opacity':1}, 200);
    jQuery('#tabs-3').animate({'opacity':0}, 200);
});

jQuery('#toolbar_tabs3').click(function(){
    jQuery('#tabs-1').animate({'opacity':0}, 200);
    jQuery('#tabs-2').animate({'opacity':0}, 200);
    jQuery('#tabs-3').animate({'opacity':1}, 200);
});

  • @ Geoff I can see your jsfiddle works fine - thank you. I think the more standard structure of jQuery UI tabs (or the one that I am familiar with) looks like this i.imgur.com/OOBG1gi.png ie using an unordered list. Will your answer work using the unordered list format or is there some problem about using an unordered list ? – Juc1 Jun 28 '14 at 21:58
  • it should work as anything really. I chose that format because that's what first came to mind... no other reason - it should be adaptable to whatever you want to use. – Geoff Jun 28 '14 at 22:29
