javascript - jQuery: How to create array with two values for each item -


i new jquery , hope can me , provide short explanation can apply similar cases in future.

i have large html page built dynamically. page contains several tables divs editable (contenteditable=true). these divs have class "editable".

now create array these divs contains id , content (text).

so far have following should create unique ids these divs incrementing number not sure on how create array this. also, out of curiosity, there term how call such arrays 2 values per item ?

my jquery: 

$('#btnsave').on('click', function(){     var = 0;     $(this).closest('form').find('div.editable').each(function(){         $(this).attr('id', 'ed' + i+1);         if( ($(this).text != '') && ($(this).text != ' ') ){             $(this).addclass('edited');         }         i++;     }); });  // attempt array (perhaps wrong approach): var arredited = new array(); $('div.edited').each(function(){     arredited.push($.trim($(this).text())); });

many in advance, mike

i don't think need loop, instead can put inside first loop, inside if( ($(this).text() != '') && ($(this).text() != ' ') ), push object array instead of value.

var arredited = new array(); $('#btnsave').on('click', function(){     $(this).closest('form').find('div.editable').each(function(index){         //you use index when use .each function         $(this).attr('id', 'ed' + (index+1));         if( ($(this).text() != '') && ($(this).text() != ' ') ){             $(this).addclass('edited');             //instead of using loop, can put code here             arredited.push({                 id: $(this).attr('id'),                 text: $.trim($(this).text())             });             //here use object, people call array of objects         }     }); });
