hashes = [
{
"type": "foo",…
},{
"type": "foo",{
"type": "bar",…
}
]
如果它的值与针列表中的项匹配,我想根据类型过滤它们：@H_502_4@
types = ['foo','quz'];
所以像@H_502_4@
<div ng-repeat="hash in hashes | filter:types"></div>
hashes = [
{
"type": "foo",…
},{
"type": "foo",{
"type": "bar",…
}

要过滤数组,您不需要完全自定义的过滤器,但我会使用谓词过滤器,您可以将其传递给Angular的过滤器.这是过滤器,假设您的数组类型：@H_502_4@
$scope.filterArray = function(hash) {
return ($scope.types.indexOf(hash.type) !== -1);
};
像这样使用：@H_502_4@
<div ng-repeat="hash in hashes | filter: filterArray">
两者都是demo fiddle@H_502_4@
自订过滤器@H_502_4@
filter('inArray',function() {
return function inArray( haystack,needle ) {
var result = [];
var item,i;
for (i=0; i< haystack.length;i++) {
item = haystack[i];
if (needle.indexOf(item.type) !== -1)
result.push(item);
};
return (result);
};
});
像这样使用：@H_502_4@
<div ng-repeat="hash in hashes | inArray: types">
