通过AngularJS中包含子字符串的属性过滤对象数组

Question

Let's say i have an array like:

array = [{
    title: "foo1",
    content: "bar1"
},{
    title: "foo2",
    content: "bar2"
},{
    title: "foo3",
    content: "bar3"
}];

Now i want to filter this array to have the objects that their title contains a character like '3'. So now my filtered array should be

filteredArray = [{
    title:"foo3",
    content: "bar3"
}];

I've tried

    filteredArray = $filter('filter')(array, {
        title: "foo3"
    });

But the problem with this is that title needs to be exactly "foo3". if i put "3" it won't filter that because it doesn't check if it contains it, it looks for an exact match.

Any ideas how to achieve this?

Answer 1

The filter filter (yeah, I know) does a contains filtering...

I pasted your code (working) into PLNKR and filtered on 3 and got back the title: 'foo3' element

array = [{
  title: "foo1",
  content: "bar1"
},{
  title: "foo2",
  content: "bar2"
},{
  title: "foo3",
  content: "bar3"
}];

$scope.filteredData = $filter('filter')(array, {
  title: "3",
});

You would need to write your own filter. Check this answer on how to achieve what you want.
