Angular JS Filtering in javascript controllers

Question

If I have something like :

{{(myList|filter:{state:"INFO"}).length}}

I am basically filtering on a specific Object property in my list. How do I do it in Javascript.

Currently the JavaScript takes only the value not the Object property.

$filter("filter")(myList,"INFO")

This works but isn't right as it looks for INFO in all object properties for single record.

$filter("filter")(myList,"INFO")

This is what I need but doesn't work as entire string is being used for filtering not treating as Object Property : Value pair

Any ideas around this ?

Answer 1

You could do:

$filter('filter')(myList,function(item){
   return (item.state == 'INFO')
});

Answer 2

An example of filtering Array of Objects based on key:value object property using Angular $filter in JavaScript | not in HTML template

var data= $filter('filter')(myList, {state: 'INFO'});

// view data
if (console) console.log(data);
