jquery - $.extend only remembers the last object added -

i'll try simplify case:

offenses = {};  $(offensetableid).find('tr').each(function (rowindex, r) {   // building json object named "offense" object    // information table row.    // console.log shows it's correct. typically have 3 rows    // showing different information.   // trying extend offenses constructed.                       $.extend(offenses, offense);  });  // after i'm done i'm printing "offenses" json object,  // expecting include added, if  // $.extend multiple times - remembers last json  // object $.extend'ed  why?   console.log(json.stringify(offenses)); 

this because objects must have unique keys. can't append new object existing object , expect useful. want array of objects.

offenses = [];  $(offensetableid).find('tr').each(function (rowindex, r) {   // building object named "offense" object    // information table row.    // console.log shows it's correct. typically have 3 rows    // showing different information.     // trying extend offenses constructed.                        offenses.push(offense);  }); 

this result in array looks this:

[{name:'bob'},{name:'frank'}] 

you can stringify json:

[{"name":"bob"},{"name":"frank"}]
