hi guys,
i want to realize a slide box in modal for images that accords with:
1 the modal is fullscreen
2 images are responsive with full height in landscape mode or full width in portrait while rotating the screen and align center in horizontal or vertical
i use directive “adaptive” to change the css style of images, but i can’t get the size of them until they have been loaded, so images are not positioned correctly. the code like below:
================================
// foo.html
<!DOCTYPE html>
<html ng-app="adaptiveSlider">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0" />
<title>Ionic Seed App</title>
<link href="lib/ionic/css/ionic.css" rel="stylesheet">
<link href="css/foo.css" rel="stylesheet">
<script src="lib/ionic/js/ionic.bundle.min.js"></script>
<script src="js/foo.js"></script>
<script src="cordova.js"></script>
</head>
<body ng-controller="mainCtrl">
<ion-header-bar class="bar-energized">
<h1 class="title">slide box in modal</h1>
</ion-header-bar>
<ion-content>
<div class="list">
<div class="item item-thumbnail-left" ng-click="openModal()">
<h2>hehe</h1>
<p>lala<br>llld</p>
</div>
</div>
</ion-content>
<script id="modal.html" type="text/ng-template">
<div class="modal modal-slide">
<ion-slide-box>
<ion-slide class="slide-in-modal" ng-repeat="image in images">
<img ng-src="{{image.url}}" adaptive></img>
</ion-slide>
</ion-slide-box>
</div>
</script>
</body>
</html>
//foo.js
var images = [{url:'img/1.jpg'},{url:'img/2.jpg'},{url:'img/4.jpg'}];
var adaptiveSlider = angular.module("adaptiveSlider",['ionic']);
adaptiveSlider.controller("mainCtrl",function($scope,$ionicModal, $ionicSlideBoxDelegate, $timeout) {
$ionicModal.fromTemplateUrl('modal.html', {
scope: $scope,
animation: 'slide-in-up'
}).then(function(modal) {
$scope.modal = modal;
$scope.images = images;
});
$scope.openModal = function() {
$scope.modal.show();
$timeout( function() {
$ionicSlideBoxDelegate.update();
});
};
$scope.closeModal = function() {
$scope.modal.hide();
};
});
adaptiveSlider.directive('adaptive',function(){
var w = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
var h = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;
return{
link: function(scope, element, attrs, controller){
var ow = element[0].width;
var oh = element[0].height;
if(w>h){
element[0].style.marginTop = "0px";
element[0].style.height = "100%"; //landscape：full height
var w1 = ow*h/oh;
var margin = (w-w1)/2+"px";
element[0].style.marginLeft = margin;
}
else{
element[0].style.marginLeft = "0px";
element[0].style.width = "100%"; //portrait：full width
var h1 = oh*w/ow;
var margin = (h-h1)/2+"px";
element[0].img.style.marginTop = margin;
}
i = null;
}
};
});
// foo.css
.modal.modal-slide{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
.slide-in-modal{
display:table-cell;
text-align: center;
vertical-align:middle;
}
