问题描述
我在我的控制器定义如下CHAPS:
I have chaps defined in my controller like this:
$scope.chaps = [{"id":"1","chap_no":"1","name":"chap 1"},
{"id":"2","chap_no":"2","name":"chap 2"},
...
{"id":"14","chap_no":"14","name":"chap 14"},
{"id":"15","chap_no":"15","name":"chap 15"}];
和中观,我有:
<li ng-repeat="ch in chaps | orderBy:'chap_no'">{{ch.name}}</li>
但我得到了错误的顺序(20 2后1 10后等)
but I'm getting the wrong order (10 after 1, 20 after 2, and so on)
chap 1, chap 10, chap 11, chap 12, chap 13, chap 14, chap 15, chap 2, chap 3, ...
这里的plunkr:<一href=\"http://plnkr.co/edit/Pc84ooB6dp2zoHXeawYn?p=$p$pview\">http://plnkr.co/edit/Pc84ooB6dp2zoHXeawYn?p=$p$pview
谁能告诉我,我做错了什么在这里
Can anyone tell me what I'm doing wrong here
推荐答案
您 chap_no
属性是一个字符串,因此其作为一个字符串命令。
Your chap_no
property is a string so its ordered as a string.
您可以创建自定义过滤器
这样的:
You can create a custom filter
like:
app.filter('customSort',function(){
function sort (a, b) {
if (a > b) { return 1; }
if (a < b) { return -1; }
return 0;
}
return function(arrInput, prop) {
var arr = arrInput.sort(function(a, b) {
return sort(+a[prop], +b[prop]);
});
return arr;
}
})
于是在你的HTML,你可以使用过滤器是这样的:
So then in your html you can use the filter like this:
<li ng-repeat="ch in chaps | customSort:'chap_no'" >{{ch.name}}</li>
