我有这样的对象:
students = {name: 'Aa_Student', class: 'A_Class'},
{name: 'Ab_Student', class: 'A_Class'},
{name: 'Ac_Student', class: 'B_Class'},
{name: 'Ba_Student', class: 'B_Class'},
{name: 'Bb_Student', class: 'C_Class'},
{name: 'Bc_Student', class: 'C_Class'}
假设学生对象被洗牌。我使用ng-repeat来显示数据。我想按自定义顺序对对象进行排序。
例如,我想显示如下数据:
Name Class
-----------------------------
Ac_Student B_Class
Ba_Student B_Class
Aa_Student A_Class
Ab_Student A_Class
Bb_Student C_Class
Bc_Student C_Class
所以基本上,我想按学生的班级排序,但它首先是B_Class,然后是A_Class,然后是C_Class。另外,我想按字母顺序按学生姓名订购。我怎么能这样做?
HTML:
<table>
<tr ng-repeat="student in students | orderBy:customOrder">
...
</tr>
</table>
控制器:
$scope.customOrder = function(student) {
$scope.students = $filter('orderBy')(student, function() {
});
};

您好,您可以创建自定义排序过滤器,请参阅此处http://jsbin.com/lizesuli/1/edit
html:
<p ng-repeat="s in students |customSorter:'class'">{{s.name}} - {{s.class}} </p>
</div>
angularjs过滤器:
app.filter('customSorter', function() {
function CustomOrder(item) {
switch(item) {
case 'A_Class':
return 2;
case 'B_Class':
return 1;
case 'C_Class':
return 3;
}
}
return function(items, field) {
var filtered = [];
angular.forEach(items, function(item) {
filtered.push(item);
});
filtered.sort(function (a, b) {
return (CustomOrder(a.class) > CustomOrder(b.class) ? 1 : -1);
});
return filtered;
};
});

知道这已经过时但可能会为其他人派上用场......
您还可以创建一个简单的自定义排序功能。 “不太过滤”:
$scope.customOrder = function (item) {
switch (item) {
case 'A_Class':
return 2;
case 'B_Class':
return 1;
case 'C_Class':
return 3;
}
};
然后像你想要的那样使用:
<table>
<tr ng-repeat="student in students | orderBy:customOrder">
...
</tr>

将orderBy
设置为对象的属性,只需引用标记中的属性名称:
ng-repeat="student in students |orderBy:'name' | orderBy:'class'"
