我在选择之后尝试禁用选项。这取决于与每个'cusomter_no'相关联的'perf_no'，如以下代码所示。当ngChange仍在更新模型时，它会更新关联对象中“禁用”的值。 debome的ngModelOptions对我不起作用。 有没有办法在ngChange完成后进行回调以更新该对象的'disabled'值？或者更好的方法来实现这一目标？提前致谢。
<div class="session-registrant-field field-dropdown">
<label for="">{{nameLbl}}</label>
<select
ng-model="affiliateSelected[cartPerf.perf_no][$index]"
ng-change="changedAffiliate(affiliateSelected, cartPerf.perf_no, $index, affiliateSelected[cartPerf.perf_no][$index].customer_no)"
ng-options="affiliate.fname + ' ' + affiliate.lname disable when affiliate.disabled for affiliate in affiliates | filter:cartPerf.perf_no | orderBy:affiliate.customer_no:true track by affiliate.customer_no"
required>
<option value="" disabled="">-- Select person --</option>
</select>
</div>

答案 0 :(得分：0)
嗯，也许它不漂亮，但是做好自己的工作（plnkr）：
$scope.passMe;
$scope.changedAffiliate = function(selectedItem, cartPerfNo, index, affiliateCustomer_no) {
if ($scope.passMe) {
$scope.affiliates.forEach((aff)=>{
if (aff.perf_no == $scope.passMe[0] && aff.customer_no == $scope.passMe[2]) {
selectedItem[$scope.passMe[0]][ $scope.passMe[1]] = aff
}
})
$scope.passMe = null;
}
$scope.passMe = [cartPerfNo,index,affiliateCustomer_no]
$.each($scope.affiliates, function(i) {
if(this.perf_no === cartPerfNo && this.customer_no === affiliateCustomer_no){
this['disabled'] = true;
}
});
}
这是基于以下事实：changedAffiliate在被禁用后将再运行1次。
