如何从数组中删除对象并保存以供以后使用？

Question

Originally my question was How to Remove Object from jQuery array . < Found the answer, the one from @nnnnnn. Using $.grep

My new question now is how would you save the object that you just removed?

Reason is I wish to be able to push that saved Object back into the Array if the user decides to keep it.

My networks array:

console:
networks array = [object Object],[object Object]

networks: Array[2]
    0: Object
      count: 1
      id: "6"
      label: "CompanyName"
      type: "Organization"

    1: Object
      count: 1
      id: "12622"
      label: "MyGroup"
      type: "Group"

From the other answer I'm using this to look in the networks array, find the Object with the type of "Organization" and remove it.

networks = $.grep(networks, function(o,i) { return o.type === "Organization"; }, true);

Is there a simple way to save that entire Object? So it can be pushed back in?

Thanks for taking a look!

You could assign the object inside the callback to a variable. This isn't a very clean solution, since such callbacks shouldn't have side effects IMO, but it works without making bigger changes to your code:

var obj;
networks = $.grep(networks, function(o,i) {
  if (o.type === "Organization") {
      obj = o;
      return true;
  }
  return false;
}, true);

or a bit shorter (and more confusing for people who don't know about the comma operator):

var obj;
networks = $.grep(networks, function(o,i) { 
    return o.type === "Organization" ? ((obj = o), true) : false;
}, true);
