angularjs如何删除一个元素内的对象从 ng-repeat 吗

Answer 1

解决方法 1:
使用 for ... in 循环遍历一个数组并不是正确的它不只考虑一个数组的元素。既不删去与数组的一个元素 delete 。这并不改变数组的大小。
一个相当简单的解决方案是筛选数组 ∶
vm.deleteElements = function(){
vm.classification.forEach(function (classification) {
classification.beneficiaries = classification.beneficiaries.filter(function(beneficiary) {
return !beneficiary.selected;
});
});
}

或如果浏览器支持 ES6:
vm.deleteElements = function(){
vm.classification.forEach( classification =>
classification.beneficiaries = classification.beneficiaries.filter(beneficiary => !beneficiary.selected)
);
}

Answer 2

是隐藏还是删除 ？
