javascript - Can't get data from dynamically created input fields -


i'm fiddling around js / jquery .. i'm trying create preview based on data entered in form. in 1 of input fields script adds new fields every time press tab (or in other words choose next field). these dynamic fields want retrieve data first 2 fields , put them preview. i've done run function adds number on end of id fields, names contestant_1, contestant_2 etc. based on number of fields opened. want data contestant_1 , _2 entered in boxes in preview.   made function waiting keyup event of 1 of these input fields. not able react them after have gained _1 , _2. if hard code in first field named _1, comes in preview. in pictures can see have entered boks1 , boks2 (box1 , 2 norewegian) in first 2 fields, boks1 comes up.

preview http://imgur.com/nci4ln1

this code executed when happens in field

$('#tname').keyup(update_tname); $('#contestant_1').keyup(update_contestant_1); $('#contestant_2').keyup(update_contestant_2);

this function updates last 2 have importance on this.

function update_contestant_1(){    console.log("inne update_contestant_1");    $('#preview').slidedown();    $('#pview_contestant_1').fadein();   // values preview    var contestant_1 = $('#contestant_1').val();    $('#display_contestant_1').html(contestant_1);          }

input field looks this

<lable for="contestant" class="col-md-2 control-label">contestants:</lable>  <div class="input-group input-group-option col-md-4">    <input class="form-control" type="text" id="contestant_" name="option[]"  placeholder="write contestant here..." required></input>  <span class="input-group-addon input-group-addon-remove">    <span class="glyphicon glyphicon-remove"></span>  </span>  </div>

and function creates new fields, change id , delete them

$(function () {    // variable counting how many contestants fields open    var i=0;      $(document).on('focus', 'div.form-group-options div.input-group-option:last-child input', function () {          var sinputgrouphtml = $(this).parent().html();  // uncomment comments below inherit div classes div on index page.  // not in use now, because need offset line input fields below each other          // var sinputgroupclasses = $(this).parent().attr('class');          // $(this).parent().parent().append('<div class="' + sinputgroupclasses + '">' + sinputgrouphtml + '</div>');          $(this).parent().parent().append('<div class="input-group input-group-option col-md-4 col-md-offset-2">' + sinputgrouphtml + '</div>');          // adds number @ end of id          i++;          console.log(i);          var newid='contestant_'+i;          $(this).attr('id',newid);      });        $(document).on('click', 'div.form-group-options .input-group-addon-remove', function () {          $(this).parent().remove();          // counts down next contestants field opens, has right number          i--;          console.log(i);          var newid='contestant_'+i;          $(this).attr('id',newid);      });    });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
