How to find a string in all key value pair of json In Javascript for creating an searching pipe in Angular 2

Question

I have an array of objects and I'd like to filter out objects based on matching values.

var a = [
    {name:'xyz' , grade :'x'},
    {name:'yaya' , grade :'x'},
    {name:'x' , frade:'d'},
    {name:'a',grade:'b'}
]

If I want to filter on 'x' then I'd expect the following results:

[
    {name:'xyz' , grade :'x'},
    {name:'yaya' , grade :'x'},
    {name:'x' , frade:'d'},
]

I have tried this

   a.filter(function(d) {
        return d.name.toLowerCase().indexOf(searchKey.toLowerCase()) > -1 ||
            d.grade.toLowerCase().indexOf(searchKey.toLowerCase()) > -1
    });

but I don't want hardcoded keys.

Post an answer in the dupe with Object.keys, filter, includes, some http://stackoverflow.com/a/40890687/14104 — epascarello, Nov 30 '16 at 14:21
you might consider a search with a key or over all keys. http://stackoverflow.com/a/40890778/1447675 — Nina Scholz, Nov 30 '16 at 14:24

function yourSearch (array, search) {

    return array.filter((el) => {
      for (let param in el) {
        if (el.hasOwnProperty(param) && Array.isArray(el[param])) {
          if (el[param].indexOf(search) !== -1) return true;
        }
      }
    });

}

enjoy

if without es6 replace (el) => with function (el)

getting error el[param].indexOf is not a function – Ashutosh Jha Nov 30 '16 at 14:19
fixed, one of your keys is not an array, added check – Jacek Pietal Dec 02 '16 at 15:37
