jQuery.merge() resulting length property is incorrect

[jbeckton]

I am using merge to join two arrays of DOM objects together. The resulting array has all the items in it but the length property is not being updated.

  var formOne = jQuery("#form1 > input"); //returns 3 items
  var formTwo = jQuery("#form2 > input"); //returns 4 items
  
  var fields = jQuery.merge( formOne, formTwo );
 
  console.log(fields); // shows Object length = 3 but if 
                       //I inspect the array further I see 7 elements in the array.

Merge expects its first argument to be a real Array, which will automagically maintain a correct length property. You could use this instead:

jQuery("#form1 > input").add("#form2 > input");
