AngularJS排序依据整型字段不能正常工作 [英] AngularJS orderby integer field not working properly
问题描述
我只是把从最简单的演示<一个href=\"http://docs.angularjs.org/api/ng.filter:orderBy\">http://docs.angularjs.org/api/ng.filter:orderBy而只是改变年龄的值有不同数量的数字的。它停止工作，因为它的预期。它的排序，如串不作为整的价值。我应该如何改变它，使它按年龄像整数定购？

codeS是：
功能Ctrl键（$范围）{
$ scope.friends =
[{名称：'约翰'，电话：555-1212，年龄：'2352345'}，
{名称：'玛丽'，电话：555-9876，年龄：'4235243'}，
{名称：'迈克'，电话：555-4321，年龄：'241'}，
{名称：'亚当'，电话：555-5678，年龄：'34325'}，
{名称：'朱'，电话：555-8765，年龄：'1234'}]
$范围predicate ='-age'。
}

您必须转换年龄键入号码，显示为排序依据，因为它应该工作。
添加到您的控制器进行排序字符串年龄作为浮动：
angular.forEach（$ scope.friends，功能（朋友）{
friend.age = parseFloat（friend.age）;
}）;
它应该工作，

I just took the simplest demo from http://docs.angularjs.org/api/ng.filter:orderBy and just change the value of age to have different number of digit. It stop working as it expected. Its ordering like "string" not as "integer" value. How should i change it so that it order by age like integer value?
Plunkr demo is here http://plnkr.co/edit/pzgiIYrki7jUZdVaTMt9?p=preview
Codes are:
function Ctrl($scope) {
$scope.friends =
[{name:'John', phone:'555-1212', age:'2352345'},
{name:'Mary', phone:'555-9876', age:'4235243'},
{name:'Mike', phone:'555-4321', age:'241'},
{name:'Adam', phone:'555-5678', age:'34325'},
{name:'Julie', phone:'555-8765', age:'1234'}]
$scope.predicate = '-age';
}

<th><a href="" ng-click="predicate = 'age'; reverse=!reverse">Age</a></th>
</tr>
<tr ng-repeat="friend in friends | orderBy:predicate:reverse">
<td>{{friend.name}}</td>
<td>{{friend.phone}}</td>
<td>{{friend.age}}</td>
</tr>
</table>
</div>

you have to convert age to type Number to make to orderBy to work as it should.
Add to your controller to sort String age as float:
angular.forEach($scope.friends, function (friend) {
friend.age = parseFloat(friend.age);
});
It should work,
