ng-model不会在ng-repeat中绑定，而其他所有内容都可以

我尝试使用controller.mu.tag的名称，但这也不起作用我尝试做mu ['tag']，但这也不起作用我尝试使用{{我将其更改为ng-bind = {{mu.tag}}，它确实有效对我来说很奇怪，它适用于ng-bind，但不适用于ng-model....无论如何，有人有什么想法吗? 解决方案似乎您想要的是将ng-model属性绑定到mu.tag的 value mu.tag本身.由于解析ng-model的方式，您需要使用方括号语法的变体才能使其实现.此处的正确语法是$parent[mu.tag]，它将在$parent对象上查找由mu.tag的值命名的属性. ng-repeat的父级是$scope，因此最终以正确对象上的属性结束.<input ng-model="$parent[mu.tag]" name="{{mu.tag}}" type="checkbox" /> http://plnkr.co/edit/RZNDa2XVUoZp1z7QeN46?p=preview I know there are a ton of questions already on this topic, I tried the solutions I found but it doesnt seem to work.Basically I have this directive called basicMunch that goes through an array of objects and creates some html.Everything works nicely and bind other than the ng-modalHere is the code for the directive: > munches.directive('basicmunches', function() { return {> require: 'ngModel',> template:`<div class='columns'> <div ng-repeat="mu in basicMunches" class="card column col-4 col-sm-12">> <div class="card-header">> <h4 class="card-title">{{mu.name}}</h4>> <h6 class="card-subtitle">{{mu.type}}</h6>> </div>> <div class="card-body">> {{mu.text}}> </div>> <div class="card-footer">> <div class="form-group">> <label class="form-switch">> <input ng-model="mu.tag" name="{{mu.tag}}" type="checkbox" />> <i class="form-icon"></i> Turn On> </label>> </div>> </div>> </div></div>` } });Here is the array: $scope.basicMunches = [ {"name":"The New York TImes", "text":"Get the top headlines from the NYT every morning", "type":"News", "tag":"nyt" }, {"name":"Wall Street Journal", "text":"Get the top headlines from the WSJ every morning", "type":"News", "tag":"wsj" }];Here is what i see in the console I have tried doing $parent.mu.tag and $parent.$parent.mu.tag, but that didnt work as it shouldnt have because it isnt nested in some other scope (atleast not that I know of)I tried doing the name of the controller.mu.tag, that too doesnt workI tried doing mu['tag'] and that doesnt work eitherI tried using {{ and that doesnt workI changed it to ng-bind={{mu.tag}} and that does workIt is weird to me that it works for ng-bind but it doesnt work for ng-model....Anyhow, anyone have any ideas? 解决方案 It seems like what you are wanting is to bind the ng-model property to the value of mu.tag, rather than to mu.tag itself.Due to the way that ng-model is parsed, you need to use a variation of the bracket syntax in order to make this possible. The proper syntax here is $parent[mu.tag] which will look on the $parent object for the property named by the value of mu.tag. The parent of the ng-repeat is $scope, so this ends up with the property on the correct object.<input ng-model="$parent[mu.tag]" name="{{mu.tag}}" type="checkbox" />http://plnkr.co/edit/RZNDa2XVUoZp1z7QeN46?p=preview 这篇关于ng-model不会在ng-repeat中绑定，而其他所有内容都可以的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
