javascript - How can I add new content to the contents of a variable and then replace that variable? -

my title might not worded , i'm sorry that. essentially, want done this:

newc = 'wow'     jquery(".bleh").each(function(i){        var bluh = *this changes everytime statement run. lets call x1, x2 , on*        var newc = bluh + newc     }); 

suppose .each() function run twice (because there 2 elements class "bleh"). need newc 'x2x1wow' .
in first time ran add value if bluh (x1) 'wow' (initial value of newc)
second time adds new value of bluh (x2) 'x1wow' (because value of newc now) return newc = x2x1wow

how achieve this?

you need create variable outside function, otherwise changes lost when function exits:

var newc = 'wow' jquery(".bleh").each(function(i) {    var bluh = *this changes everytime statement run. lets call x1, x2 , on*    newc = bluh + newc }); 

the problem in side each callback variable newc declared local variable resetted in every iteration. need modify closure variable newc declared outside loop, can remove var in callback function
