问题:如何清除动态创建的ng-repeat AngularJS 表单字段？如果你能找到一个我没有寻找答案的地方，我会感到惊讶。
背景:我有 AngularJS 通过服务将 JSON 拉入我的 Controller 。然后我使用范围来重复表单的标签。我在清理字段时遇到问题。因为文字并不能准确地告诉你我在这里做什么是基本的代码设置。我把它改成了几行。
我试过旧的 $scope.formName.inputName="";和 $scope.inputName=""; ，但它们不起作用。有什么想法或方向吗？

最佳答案
您正在重复一个 ngmodel="forminput"通过使 forinput 成为一个对象并使用键创建唯一模型来为每个使用唯一的模型 ng-model="forminput[item.desc]"
首先在您的 Controller 中
$scope.forminput = {};
然后在 View 中，将输入更改为
演示:
// Code goes here
var app = angular.module("app", []);
app.controller("AppTest", function($scope) {
$scope.forminput = {};
$scope.currentInfo = {
"attribute": [
{
"name": "ACCT",
"desc": "Account #",
},
{
"name": "FNAME",
"desc": "First Name",
"type": "VARCHAR",
"validation": "^[a-zA-Z\\s]+"
},
{
"name": "LNAME",
"desc": "Last Name",
"type": "VARCHAR",
"validation": "^[a-zA-Z\\s]+"
},
{
"name": "MNAME",
"desc": "Middle Name",
"type": "CHAR",
"validation": "^[a-zA-Z]+[1-9]+"
}
]
};
$scope.clearMe = function (){
console.log("herleme")
$scope.forminput = {};
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app" ng-controller="AppTest as app">
<h1>Hello Plunker!</h1>
<form name="formName" id="formName">
<div ng-repeat="item in currentInfo.attribute">
<div style="float:left;">{{item.desc}} </div>
<div > <input name="forminput[item.desc]" ng-model="forminput[item.desc]" style="width:200px" type="text" value=""/>
</div>
</div>
<button value="Clear" ng-click="clearMe()">Clear</button>
</form>
</body><input name="forminput[item.desc]"
ng-model="forminput[item.desc]"
style="width:200px" type="text" value=""/>
并将其清除为
$scope.clearMe = function (){
console.log("herleme")
$scope.forminput = {};
};
