使用Return打破循环。

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

试试这个作为休息;

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

使用Return打破循环。

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

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;
    }
}

只需添加$index并执行以下操作:

angular.forEach([0,1,2], function(count, $index) {
     if($index !== 1) {
          // do stuff
     }
}

这是不可能的。见https://github.com/angular/angular.js/issues/263。取决于你在做什么，你可以使用布尔值来不进入循环体。喜欢的东西:

var keepGoing = true;
angular.forEach([0,1,2], function(count){
  if(keepGoing) {
    if(count == 1){
      keepGoing = false;
    }
  }
});
