我正在开展一个角度js项目。现在控件是静态的。但客户希望基于数据库创建html控件。
我有一个包含控件规范的表
例如:
输入: text / dropdown / radio / checkbox
事件: onchange / onblur / onfocus
属性: “颜色:红”
如何生成可以将数据库值解析为html控件的动态模型?
任何帮助都会非常感激......

使用ng-repeat指令非常简单。请注意我如何将模型的值分配回ng-repeat中的范围变量。这允许我稍后检索它。
angular.module('formModule', []).
controller('DynamicFormController', ['$scope',
function($scope) {
//Set equal to json from database
$scope.formControls = [{
name: "Name",
type: "text"
}, {
name: "Age",
type: "number",
color: "red"
},
{
name: "UseNestedControls",
type: "checkbox",
nestCondition: true,
nestedControls: [{
name: "NestedText",
type: "text"
}]
}
];
}
]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="formModule">
<div ng-controller="DynamicFormController">
<form>
<div ng-repeat="input in formControls">
<label>{{input.name}}</label>
<input type="{{input.type}}" ng-model="input.value" ng-style="{'color':input.color}" />
<div ng-repeat="nestedInput in input.nestedControls" style="margin-left:20px" ng-show="input.value == input.nestCondition">
<label>{{nestedInput.name}}</label>
<input type="{{nestedInput.type}}" ng-model="nestedInput.value" ng-style="{'color':nestedInput.color}"/>
</div>
</div>
</form>
<div ng-repeat="input in formControls">
<span>{{input.name}} = {{input.value}}</span>
<div ng-repeat="nestedInput in input.nestedControls" style="margin-left:20px">
<span>{{nestedInput.name}} = {{nestedInput.value}}</span>
</div>
</div>
</div>
</body>
