我从一系列来源开始
$scope.sources = [
{
"type": "register",
"name": "Register 1",
"balance": 100
},
{
"type": "register",
"name": "Register 2",
"balance": 100
},
{
"type": "register",
"name": "Register 3",
"balance": 200
},
{
"type": "office",
"name": "Change Drawer",
"balance": 200
},
{
"type": "office",
"name": "Safe",
"balance": 500
}
];
我已成功加载选项
<div class="form-group">
<label>Transfer <strong>{{amount(count, start, selectedItem.balance) | currency}}</strong> To:</label>
<select id="transferTo" class="form-control" ng-model="form.to" ng-options="item.name for item in sources | filter:{type:'office'}">
<option value="">-- Select a Source --</option>
</select>
</div>
我尝试使用$timeout
函数在其工作后选择它,但它没有将正确的值传回我的函数
$timeout(function () {
$('#transferTo').val('1');
}, 200);
我如何设置&#34; Safe&#34;作为表单加载时选择的默认选项?
答案 0 :(得分:3)
您需要在示波器上设置一个值,该值设置的ng-model等于:
$scope.form.to = $scope.sources[4];
如果您的列表(源)是动态的,您可以像这样过滤数组,这将返回一个数组(但保持数组不变)。
filterFilter($scope.sources, {name: 'Safe'})
