问题描述
当尝试使用Ember.run.debounce时，只有当有多个子视图触发保存时，才能在父视图或控制器上触发保存操作。问题似乎是关闭（匿名函数），但是在这种情况下，我找不到在Ember中实现去抖动的最佳方法的例子。
I am trying to use Ember.run.debounce to only trigger the save action on a parent view or controller once when there are many child views triggering save. The problem seems to be closure (anonymous function), but I can't find any examples of the best way to implement debounce within Ember in this context.
这是一个jsbin概述了这个问题。任何帮助或指点赞赏！

推荐答案
您的怀疑是正确的，但解决方案非常简单。
Your suspicion is right but the solution is quite easy.
您的方法
App.GroupsView = Ember.View.extend({
templateName: 'groups_view',
actions: {
save: function () {
Ember.run.debounce(this, function() {
console.log('groups view save');
this.get('controller').send('save');
}, 1000);
}
}
});
我的解决方案提案：这样你就没有匿名功能并且Ember运行循环能够执行其去抖动逻辑。
My solution proposal: This way you don't have an anonymous function and the Ember run loop is able to do its debounce logic.
App.GroupsView = Ember.View.extend({
templateName: 'groups_view',
actions: {
save: function () {
Ember.run.debounce(this, this.saveFn, 1000);
}
},
saveFn : function(){
console.log('groups view save');
this.get('controller').send('save');
}
});
