changing value in javascript object iterated using jquery

Question

OK So I have this piece of code :

var el = {a:"b","isSel":true};
$.each(el,function(k,v){
  if(k=="isSel"){
    v=false
  }
})
console.log(el);

but that doesn't change isSel to false... any clues?

Why would you need to iterate? if ("isSel" in el) el["isSel"]=false; — adeneo

There isn't any JSON here. You just have standard old Javascript objects. — James

Change it to

var el = {a:"b","isSel":true};
$.each(el,function(k,v){
  if(k=="isSel"){
    el[k]=false // <= this sets the property named k of el
  }
})
console.log(el);

Note that if you just want to change the property named "isSel" of el, you don't have to iterate : you may simply do

el["isSel"] = false;

or

el.isSel = false;

There is no need for looping. The value can be accessed as follows:

el.isSel = false;

or

el["isSel"] = false;

Yeah I actually have a lot of nested properties, the JSON I'm handling is a bit more complicated so have to loop inward
