jquery - filter multidimensional array

I have a multidimensional array like this:

var allObj = {'@DB M-T 1@': 'DB More Than 1','@ES L-T 5@': 'ES Less Than 5','@MM E-Q 0@': 'MM Equal 0'};

and I have a criteria like this:

var criteriaArray = {'DB More Than 1','MM Equal 0'};

I would like to create a new array out of the allObj array, such that it meets the values in criteriaArray. The output should look like this:

var matchObj = {'@DB M-T 1@': 'DB More Than 1','@MM E-Q 0@': 'MM Equal 0'};

From what I gather, I can use jquery grep. But I can't figure out how to do it correctly. I would appreciate if someone can help me. I've been on this for hours.

You seem to want to filter the properties of an object (not an array) by their values.

The simplest would be to do this :

var criteriaArray = ['DB More Than 1','MM Equal 0']; // your syntax was bad
var matchObj = {}; // resulting object
for (var key in allObj) {
   if (criteriaArray.indexOf(allObj[key]) !== -1) {
       matchObj[key] = allObj[key]
   }
}

Here is an iterative solution:

var allObj = {'@DB M-T 1@': 'DB More Than 1','@ES L-T 5@': 'ES Less Than 5','@MM E-Q 0@': 'MM Equal 0'};
var criteriaArray = ['DB More Than 1','MM Equal 0'];
var matchObj = {};
for(var key in allObj) {
  var value = allObj[key];
  for(var i=0; i<criteriaArray.length; i++) {
    var criteria = criteriaArray[i];
    if(value==criteria) {
      matchObj[key] = value;
      break;
    }
  }
}
console.log(matchObj);//{'@DB M-T 1@': 'DB More Than 1','@MM E-Q 0@': 'MM Equal 0'};
