How to ignore property in angular filter
I am trying to ignore a property called title in my angular. I have a dataset as shown below:
const data = [
{
title: 'Title 1'
groups: [
{...},
{...},
{...}
]
},
{
title: 'Title 2'
groups: [
{...},
{...},
{...}
]
},
{
title: 'Title 3'
groups: [
{...},
{...},
{...}
]
}
];
And I use ng-repeat with a filter to iterate over objects and another loop to iterate over groups:
<input ng-model="search">
<div ng-repeat="item in data | filter:search">
<h1>{{item.title}}</h1>
<ul>
<li ng-repeat="group in item.group | filter:search">
<span>{{group.something}}</span>
</li>
</ul>
</div>
Works fine, but now I would like to ignore the title in the search. I tried several things like: filter:search:item.title
(in the first ng retry) or remove the first filter:search
one but all attempts failed. What am I missing? Do I need custom search or something like that?
Thank.
You can specify the properties you want to filter and leave the title:
<li ng-repeat="group in item.groups | filter: { something: search }">
The above code will only filter based on the something property.

You should create a custom filter where you can specify which property should be excluded ( ignored ) for reasons:
angular.module('app', []).controller('MyController', ['$scope', function($scope) {
$scope.data = [
{name:"Tom", title:'London'},
{name:"Max", title:'Moscow'},
{name:"Henry", title:'NY'},
{name:"Paul", title:'NY'},
{name:"Sam", title:'Paris'}
];
}]).filter('myfilter',function(){
return function(input, search, ignore){
if(!search)
return input;
var result = [];
for(var item of input)
for(var prop in item)
if(prop != ignore && item[prop].indexOf(search) != -1)
{
result.push(item) ;
break;
}
return result;
}
});
<script src="//code.angularjs.org/snapshot/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="MyController">
search: <input type='text' ng-model='search' ng-init='search="a"'/>
ignore: <input type='text' ng-model='ignore' ng-init='ignore="title"'/>
<ul>
<li ng-repeat='item in data | myfilter: search: ignore'>
{{item.name}} {{item.title}}
</li>
</ul>
</div>
</body>
