我不能为我的生活设置我的选择的默认值。它一直是空白的。啊。
<div ng-controller="quickComposeController">
<div id="QuickComposeEmail">
<form id="quickComposeForm">
<div class="modal-header">
<h3>Set email preferences</h3>
</div>
<div class="modal-body">
<select ng-init="selected=selected[0]" ng-model="selected" ng-options="o.value as o.name for o in optionsObject">
</select>
</div>
<div class="modal-footer">
<input class="btn btn-success" type="submit" value="Compose Email">
<button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</form>
</div>
</div>
这是我的控制人员:
app.controller('quickComposeController', ['$scope', function($scope){
$scope.selected = [{name : "Use Default Mail Client", value : "mailto"}];
$scope.optionsObject = [
{name : "Use Default Mail Client", value : "mailto"},
{name : "Gmail", value : "gmail"},
{name : "Yahoo", value : "yahoo"},
{name : "Hotmail", value : "hotmail"},
{name : "AOL", value : "aol"}
]
}]);
我只是在底部写下这个,因为stackoverflow告诉我我的帖子主要是代码,我需要更多文本。每个人都度过美好的一天!
答案 0 :(得分:2)
您的选择应该是:
<select ng-init="selected=selected[0].value" ng-model="selected" ng-options="o.value as o.name for o in optionsObject">
需要注意的是,您必须不仅指定正确的索引,还要指定其中的value
属性,因为您的选项基于value
。
