我有一个图像,需要通过拖动角来调整大小,angularjs中有任何选项吗？
截至目前我正在做手动图像调整大小如下:
<img src="~/Content/images/login-logo.png" width="{{image.width}}" height="{{image.size}}"/>
<div class="right-wrapper">
<h3 class="right-head">Appearance <img src="~/Content/images/info-icon.png"></h3>
<div ng-if="isImage">
<div ng-class="form-group">
size
<input class="form-control" type="textbox" ng-model="image.size" />
</div>
<div ng-class="form-group">
width
<input class="form-control" type="textbox" ng-model="image.width" />
</div>
</div>
</div>
但是我想通过拖动它来调整它的大小.
希望这个角度指令有所帮助
(function () {
'use strict';
angular.module('myApp', [])
.directive('resizable', function () {
return {
restrict: 'A',
scope: {
callback: '&onResize'
},
link: function postLink(scope, elem, attrs) {
elem.resizable({handles: "all"});
elem.on('resize', function (evt, ui) {
scope.$apply(function() {
if (scope.callback) {
scope.callback({$evt: evt, $ui: ui });
}
})
});
}
};
})
.controller('MainCtrl', function ($scope) {
$scope.resize = function(evt,ui) {
//console.log (evt,ui);
$scope.w = ui.size.width;
$scope.h = ui.size.height;
}
});
})();<head>
