Phonegap / jquery mobile slide transition not workign properly on first call
- by Alexander Casassovici
I have an awkward visual glitch.
I want nice transition when changing pages on the app.
Unfortunately first time i change to another page, Instead of sliding current pagg out and new page in , current page is immediately replaces by the new page, then slides out... and when it's out of view it's the new page is shown... the second time around it works like a charm though !!!
This is running on iphone with jquery mobile + phonegap
I made a video to make the issue clear: http://www.youtube.com/watch?v=Ybvzh_wTnSE
<body style="background-color: #000;">
<div id="container" style="display:none;">
<div id="side-menu" style="display:none;">
<div id="header_top"></div>
<a href="#dives" onclick="showdives();"><div id="header_dives" class="selected"></div></a>
<div id="header_spacer1"></div>
<a href="#explore" onclick="showexplore();"><div id="header_explore"></div></a>
<div id="header_spacer2"></div>
<a href="#search" onclick="showsearch();"><div id="header_search"></div></a>
<div id="header_spacer3"></div>
<a href="#settings" onclick="showsettings();"><div id="header_settings"></div></a>
<div id="header_bottom"></div>
</div>
<div id="slide_mask">
<!-- START of LOGIN page -->
<div data-role="page" id="login">
<div id="home_frame">
<div id="home_logo"></div>
<div id="home_fblogin" onclick="login()"></div>
<div class="home_login">
<p>Email: <input type="text" name="user[email]" size="30"/></p>
<p>Password: <input type="password" name="user[password]" size="30"/></p>
<button onclick="show_page_home();">LOGIN</button>
</div>
</div>
</div>
<!-- END of LOGIN page -->
<!-- START of LOGIN page -->
<div data-role="page" id="dives" class="right_pane">
<p>My dives !</p>
</div><!-- /content -->
<div data-role="page" id="explore" class="hidden right_pane">

<div data-role="page" id="settings" class="hidden right_pane">

<button onclick="logout_db();">logout</button>
</div><!-- /content -->
<!-- END of LOGIN page -->
</div>
</div>
<div id="log"></div>
<div id="data"></div>
</body>
And the relevant CSS:
body {margin: 0; font: 18px Helvetica; text-align: center; background-color: #000; background: url(../img/bg_big.png) repeat;
-webkit-user-select: none; /* prevent copy paste for all elements */
}
#container { width:320px; height:460px; overflow: hidden;}
input{ -webkit-user-select: text; /* enable copy paste for elements with this class */}
a {-webkit-user-select: none; /* prevent copy paste for all elements */}
span {-webkit-user-select: none; /* prevent copy paste for all elements */}
#side-menu {z-index: 1000 !important; position: fixed; height: 460px; width: 56.5px; background: url(../img/bg_big.png) no-repeat; display: inline-block;
overflow: hidden; top: 0px; left: 0px; }
#header_top {background: url(../img/header/header_top.png) no-repeat; background-size: 56.5px 48.96px; width: 56.5px; height: 48.96px; display: block;}
#header_dives {background: url(../img/header/dives.png) no-repeat; background-size: 56.5px 51.75px; width: 56.5px; height: 51.75px; display: block;}

#header_explore{background: url(../img/header/explore.png) no-repeat; background-size: 56.5px 51.75px; width: 56.5px; height: 51.75px; display: block;}

#header_settings.selected{background: url(../img/header/settings_selected.png) no-repeat;}
#header_bottom{background: url(../img/header/header_bottom.png) no-repeat; background-size: 56.5px 160px; width: 56.5px; height: 160px; display: block;}
.hidden {display: none;}
.right_pane{width: 263.5px !important; background: url(../img/right_bg.png) no-repeat; background-size:263.5px 460px; width: 263.5px; height: 460px; left: 56.5px !important;}
#slide_mask{ display: inline-block; overflow: hidden; padding-left: 56.5px; width: 263.5px; height: 460px; top: 0;}
and the bit of JS:
///////////////////////////////////
//MENU MECHANICS
///////////////////////////////////
function showdives(){
$("#side-menu .selected").removeClass("selected");
$("#header_dives").addClass("selected");
}
function showexplore(){
$("#side-menu .selected").removeClass("selected");
$("#header_explore").addClass("selected");
}
function showsearch(){
$("#side-menu .selected").removeClass("selected");
$("#header_search").addClass("selected");
}
function showsettings(){
$("#side-menu .selected").removeClass("selected");
$("#header_settings").addClass("selected");
}
the onclick only add/remove the "selected" class to the menu items
so... any hint ? been trying eveything for hours and still can't get it neat .. :(
