Question

我想显示某些复选框值。应从控制器调用这些值。因为，我需要保存值，我最好在控制器中声明值，然后在html中使用它。使用我的代码，我无法从控制器获取值。我的代码，

{{ngapp}}.controller(
        "SAdController",
        function($scope){

$scope.items = [{
	name: 'Printability',
	value: true
	}, {
	name: 'Defectivity',
	value: true
	}, {
	name: 'Process Window',
	value: true
	}, {
	name: 'Parametric Shift',
	value: true
	}, {
	name: 'Yield Impact',
	value: true
	}, {
	name: 'Reliability',
	value: true
	}, {
	name: 'Other',
	value: true
}];

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!-- HTML -->

<div class="form-group">
  <td><label>Main Concern</label></td>
  </br>
  <tr><input type="checkbox" ng-model="arform.mainconcern" ng-repeat="item in items"
                          
    <td>{{item.name}}</td>
  </tr>
</div>

我确实寻找过类似的头衔，遗憾的是我没有得到合适的解决方案。有人可以帮忙吗？谢谢。

Answer 1

你的ng-model不正确：将您的ng-model="item.value"更改为$(".currency-target").change(function () { $.ajax({ url: "currency.txt", dataType: "text", success: function (data) { var CurrVal = $('.currency-target :selected').val(); data = data.split("\r\n"); for (var i = 0; i < data.length; i++) { element = data[i].split(": "); //element[0] as key and element[1] as value if (CurrVal == element[0]) { alert(element[0] + "=>" + element[1]); } } } }); });，您应该好好去。

IMO，当你有多个复选框元素时，你应该使用ng-repeat和父元素。

<li ng-repeat="item in items">
     <input type="checkbox" ng-model="item.value" />{{item.name}}
</li>

此外，您可以根据需要使用ng-checked, ng-true-value, ng-false-value。
