How to implement page adaptation in angularjs?
This article mainly introduces the method of adaptive height of angularjs page. Now I will share it with you and give you a reference.
Requirements
In the business system built with angularjs, page jumps are implemented through ui-view routing. After initializing and entering the system, the content area on the right needs adaptive browsing. device height.
Implementation plan
Add directive to p where ui-view is located, calculate the height of p through element.css initialization in the directive, and update it dynamically p height
Directive monitors ($$watch)angular's $digest, obtains the body height in real time, and dynamically assigns model or element.css changes
Option 1: Add directive and element.css adaptive height
1. Create directive
define([ "app" ], function(app) {
app.directive('autoHeight',function ($window) {
return {
restrict : 'A',
scope : {},
link : function($scope, element, attrs) {
var winowHeight = $window.innerHeight; //获取窗口高度
var headerHeight = 80;
var footerHeight = 20;
element.css('min-height',
(winowHeight - headerHeight - footerHeight) + 'px');
}
};
});
return app;
});2.p element add directive
<p ui-view auto-height></p>
3 .Rendering
Original interface: The height of the right area is adaptive content, resulting in a black background color below
After adjustment: The right area Height-adaptive browser
Option 2: $watch monitors the body height and assigns a value to change the height
1. Create a resize directive
var app = angular.module('miniapp', []);
function AppController($scope) {
/* Logic goes here */
}
app.directive('resize', function ($window) {
return function (scope, element) {
var w = angular.element($window);
scope.getWindowDimensions = function () {
return { 'h': w.height(), 'w': w.width() };
};
scope.$watch(scope.getWindowDimensions, function (newValue, oldValue) {
scope.windowHeight = newValue.h;
scope.windowWidth = newValue.w;
scope.style = function () {
return {
'height': (newValue.h - 100) + 'px',
'width': (newValue.w - 100) + 'px'
};
};
}, true);
w.bind('resize', function () {
scope.$apply();
});
}
})2. Add the resize directive to the p element
<p ng-app="miniapp" ng-controller="AppController" ng-style="style()" resize>
window.height: {{windowHeight}} <br />
window.width: {{windowWidth}} <br />
</p>The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
