如何在 ng-option 上使用 ng-click(或其他赋值方式)
How to use ng-click on ng-option( or other way to assign value)
如何使用ng-options.
$scope.fieldTable = [
{
filed:"text",
title:"Global"
},
{
field: "relatedentity",
title: "Entity"
},
{
field:"title",
title:"Title"
},
{
field: "content",
title: "Content"
}
]
我想构建一个使用显示的标题,当 select 某些内容时,弹出一个显示相应字段的警报 window。最初的 selection 是
{
filed:"text",
title:"Global"
}
有人能帮忙吗?
您可以使用 ng-change 来做到这一点
<select ng-options="item.title as item.title for item in fieldTable track by item.title" ng-model="selected" ng-change="onChanged()">
然后在控制器的 onChange() 方法中,您可以做任何您想做的事 :) 在您的情况下,显示值为
的警报
var app = angular.module('stack', []);
app.controller('MainCtrl', function($scope) {
$scope.fieldTable = [{
field: "text",
title: "Global"
}, {
field: "relatedentity",
title: "Entity"
}, {
field: "title",
title: "Title"
}, {
field: "content",
title: "Content"
}];
$scope.selected = $scope.fieldTable[0];
$scope.hasChanged = function() {
alert($scope.selected.field);
}
});

<body ng-app="stack" ng-controller="MainCtrl">
<select ng-options="item.title for item in fieldTable" ng-model="selected" ng-change="hasChanged()">
</select>
