ng-repeat :filter by single field

2018-12-31 14:10发布

I have an array of products that I'm repeating over using ng-repeat and am using

<div ng-repeat="product in products | filter:by_colour"> 

to filter these products by colour. The filter is working but if the product name / description etc contains the colour then the product remains after the filter is applied.

How do I set the filter to only apply to the colour field of my array rather than every field?

my way is this

subjcts is

[{"id":"1","title":"GFATM"},{"id":"2","title":"Court Case"},{"id":"3","title":"Renewal\/Validity"},{"id":"4","title":"Change of Details"},{"id":"5","title":"Student Query"},{"id":"6","title":"Complains"}]

sub is a Input field or whatever you like

Displaying like this

<div ng-if="x.id === sub" ng-repeat=" x in subjcts">{{x.title}}</div>

If you were to do the following:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

...you would not only get items of itemTypeId 2 and itemStatus 1, but you would also get items with itemType 20, 22, 202, 123 and itemStatus 10, 11, 101, 123. This is because the filter: {...} syntax works like a string contains query.

However, if you were to add the : true condition, it would do filter by exact match:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } : true | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

If you want filter for one field:

label>Any: <input ng-model="search.color"></label> <br>
<tr ng-repeat="friendObj in friends | filter:search:strict">

If you want filter for all field:

 label>Any: <input ng-model="search.$"></label> <br>
 <tr ng-repeat="friendObj in friends | filter:search:strict">

and https://docs.angularjs.org/api/ng/filter/filter good for you

Best way to do this is to use a function:

html

<div ng-repeat="product in products | filter: myFilter">

javascript

$scope.myFilter = function (item) { 
    return item === 'red' || item === 'blue'; 
};

Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.

You must use filter:{color_name:by_colour} instead of

filter:by_colour

If you want to match with a single property of an object, then write that property instead of object, otherwise some other property will get match.

Search by color:

<input type="text" ng-model="searchinput">
<div ng-repeat="product in products | filter:{color:searchinput}">

you can do an inner nest too.

filter:{prop1:{innerprop1:searchinput}}
