Late binding onclick event

Question

Following part of my javscript(using jquery).

list = [\'a\', \'b\', \'c\'];
for(var i = 0 ; i< list.length ; i++) {
   $(\"click here\").
          


        

Answer 1

You'll need a closure new scope as the iteration finishes before the event handler is triggered, so when the click happens, the loop has finished and i is the last value it's set to, a new scope keeps the value of i local to that scope

list = ['a', 'b', 'c'];

for(var i=0; iclick here").click(function(){
          foo(list[j]);
       }).appendTo('#sometag');

   }(i));

}

function foo(val) {
    console.log(val);
}

Another option is to add more jQuery

list = ['a', 'b', 'c'];

$.each(list, function(index, item) {
    $("", {text : 'click here',
                on   : {
                    click : function() {
                        foo(item);
                    }
                }
    }).appendTo('#sometag');
});

function foo(val) {
    console.log(val);
}
