I am using UnderscoreJs in my project. I have to filter an array containing object having properties. I need to filter based on the values. The value can be of any property of the object. ex: "mini" should fetch both "toyota" and "Honda" since "mini" is present as part of both the objects

[{ name:"Toyota minivan", id:"506", size: "large" }, { name:"Honda Civic", id:"619", size: "mini" }]

How to do using Underscore. I have tried the following approach but not working.

var searchStr="mini";
var evens = _.filter([arrayData], function(obj){ return _.contains(obj, searchStr); });

Can you please let me know where I am going wrong?

_.contains only works on arrays, so you need to grab the values from each object first and then check if any of them contain the search string. I've used some in this example, together with indexOf to match the string.

var searchStr="mini";
var mini = _.filter(arr, function (obj) {
    return _.values(obj).some(function (el) {
        return el.indexOf(searchStr) > -1;
    });
});

Well, I have done this with simple if condition so that in future if you want to list mini in one array and large in one array so you can do easily. I have checked the object property if matched then assigned to new list. here is my code. and check out demo here fiddle

 var list=[{ name:"Toyota minivan", id:"506", size: "large" }, 
              { name:"Honda Civic", id:"619", size: "mini" },
              {name:"zen",id:"606",size:"mini"}]; 
   var result=_.filter(list, function(obj){
                  if(obj.size=='mini'){ 
                    var matchedcars=obj; 
                    console.log("result"+JSON.stringify(matchedcars));
                  } 
                   return matchedcars;
   });
     alert("result"+JSON.stringify(result));
