Question

我找到了要打印的解决方案：

  function Print() {
  if (document.queryCommandSupported('print')) {
document.execCommand('print', false, null);
  }
  else {
    window.parent.<framename>.focus();
    window.print();
  }
}

尽管我有几个iframe，而不只有一个。对于多个iframe，最好的书写方式是什么？

我认为document.execCommand（'print'，false，null）与window.print（）方法类似，您可以使用其中任何一个来打印整个页面。

<!DOCTYPE html>
    <html>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
    <body>

    <div ng-app="myApp" ng-controller="myCtrl">

    <select id="nameField" class="form-control" ng-model="selectedOption" ng-change="fillDataType()" ng-options="obj.name for obj in userDefinedWorkflowVariables">
                    
                    </select>
                    
                    

    </div>



    <script>
    var app = angular.module('myApp', []);
    app.controller('myCtrl', function($scope) {
    $scope.selectedOption={};
        
       $scope.userDefinedWorkflowVariables = [{name:"object1",dataType:"number",description:"description1"},
    {name:"object2",dataType:"number",description:"description2"}]

    $scope.selectedOption =$scope.userDefinedWorkflowVariables[0]


    $scope.fillDataType = function() {
       console.log( $scope.selectedOption) 
       var dataType =  $scope.selectedOption.dataType;

    }
    });
    </script>

    </body>
    </html>
