这是我的HTML:
<div ng-repeat="n in items">
<ul ng-repeat="(name, param) in n.params" style="list-style-type: none;">
<li>{{name}} : {{param}}</li>
</ul>
<input style="display:inline;width:130px;margin-bottom:5px;margin-top:5px;"
class="form-control" name="text" placeholder="age"
ng-model="age">
<input style="display:inline;width:115px;margin-bottom:5px;margin-top:5px;"
class="form-control" name="text" placeholder="weight"
ng-model="weight">
<br />
<button class="btn btn-warning" type="button"
ng-click="add(n.params , age , weight)">Update</button>
</div>
我的JS:
$scope.items = [
{
"params": {
"age": 22,
"weight": 66
}
},
{
"params": {
"age": 19,
"weight": 54
}
},
{
"params": {
"age": 17,
"weight": 75
}
}
]
$scope.add = function(params , age, weight) {
$scope.params = params;
if(age)
$scope.params.age = age;
if(weight)
$scope.params.weight = weight;
console.log($scope.params);
}
我想编辑完全类似于我的示例中的数组,但是看起来像这样:
<ul ng-repeat="(name, param) in n.params" style="list-style-type: none;">
<li>{{name}} :
<input style="display:inline;width:130px;margin-bottom:5px;margin-top:5px;"
class="form-control" name="text" placeholder="param"
ng-model="param">
</li>
</ul>

ng-repeat
指令创建一个子范围,当ng-model
属性指定基元时隐藏值:
<div ng-repeat="n in items">
<ul>
<li ng-repeat="(key, value) in n.params">
{̶{̶k̶e̶y̶}̶}̶ ̶:̶ ̶<̶i̶n̶p̶u̶t̶ ̶n̶g̶-̶m̶o̶d̶e̶l̶=̶"̶v̶a̶l̶u̶e̶"̶>̶
{{key}} : <input ng-model="n.params[key]">
</li>
</ul>
</div>
通过遵循&#34;最佳实践&#34;可以很容易地避免使用原语这个问题。总是有一个&#39;。在您的ng模型中。
