导读: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
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. 解决方法
希望这个角度指令有所帮助
