我会用return代替break。

angular.forEach([0,1,2], function(count){
  if(count == 1){
    return;
  }
});

效果非常好。

效果非常好。

$scope.arr = [0, 1, 2];  
$scope.dict = {}
for ( var i=0; i < $scope.arr.length; i++ ) {
    if ( $scope.arr[i] == 1 ) {
        $scope.exists = 'yes, 1 exists';
        break;
    }
 }
 if ( $scope.exists ) {
     angular.forEach ( $scope.arr, function ( value, index ) {
                      $scope.dict[index] = value;
     });
 }

这个例子有用。试一试。

var array = [0,1,2];
for( var i = 0, ii = array.length; i < ii; i++){
  if(i === 1){
   break;
  }
}

你可以用这个:

var count = 0;
var arr = [0,1,2];
for(var i in arr){
   if(count == 1) break;
   //console.log(arr[i]);
}

onSelectionChanged(event) {
    let selectdata = event['api']['immutableService']['gridOptionsWrapper']['gridOptions']['rowData'];
    let selected_flag = 0;

    selectdata.forEach(data => {
      if (data.selected == true) {
        selected_flag = 1;
      }
    });

    if (selected_flag == 1) {
      this.showForms = true;
    } else {
      this.showForms = false;
    }
}
