我可以安慰你。正确记录所有值,但未计算表达式img ng src=“{{$scope.bus}”。我对angularJs很陌生,任何帮助都会很好。下面是代码

$scope.showAdvanced = function (ev, bus) {

      $scope.bus = bus;
      console.log(bus);
      console.log("scope.bus ="+$scope.bus);
      $mdDialog.show({
        controller: DialogController,
        template: '<div role="dialog" aria-label="Eat me!" layout="column" layout-align="center center">' +
          '    <md-toolbar>' +
          '      <div class="md-toolbar-tools">' +
          '        <h2>Surprise!</h2>' +
          '      </div>' +
          '    </md-toolbar>' +
          '  ' +
          '   <div ' +
          '    <div id="slideDiv" class="demo-dialog-content">' +
          '      <div layout="row" >' +
          '        <img ng-src="{{$scope.bus}}">' +
          '      </div>' +
          '    </div>' +
          '  ' +
          '    <div layout="row" class="demo-dialog-button">' +
          '      <md-button md-autofocus flex class="md-primary" ng-click="cancel()">' +
          '        Close' +
          '      </md-button>' +
          '    </div>' +
          '  </div>',
        parent: angular.element(document.body),
        targetEvent: ev,
        clickOutsideToClose: true,
        fullscreen: $scope.customFullscreen // Only for -xs, -sm breakpoints.
      })
    };

$scope在这种情况下不起作用,因为它是一个孤立的。你能试试添加吗 当地人 谢谢

locals: {bus: $scope.bus}

或

下面是第一种方法。

locals: {parent: $scope}
