jQuery的動態添加表格字段，刪除表格字段

Question

你好我試圖從本教程中得到啓發後添加新的表單字段和刪除表單字段 - http://bootsnipp.com/snipps/dynamic-form-fields

我目前的問題是刪除並重新設置所有的值按時間順序排列。

<input type="hidden" name="count" value="1" /> 
<div class="control-group" id="fields"> 
      <label class="control-label" for="field1">Nice Multiple Form Fields</label> 
      <div class="controls" id="profs"> 
      <div class="input-append"> 
       <input autocomplete="off" class="span3" id="field1" name="prof1" type="text" placeholder="Type something (it has typeahead too)" data-provide="typeahead" data-items="8" 
data-source='["Aardvark","Beatlejuice","Capricorn","Deathmaul","Epic"]'/><button id="b1" onClick="addFormField()" class="btn btn-info" type="button">+</button> 
      </div> 
      <br /><small>Press + to add another form field :)</small> 
      </div> 
     </div> 

的Javascript： -

var next = 1; 

function addFormField(){ 
    var addto = "#field" + next; 
    next = next + 1; 
    var newIn = '<br /><br /><input autocomplete="off" class="span3" id="field' + next + '" name="field' + next + '" type="text" data-provide="typeahead" data-items="8"><button id="b1" onClick="$(this).parent().remove();" class="btn btn-info" type="button">+</button>'; 
    var newInput = $(newIn); 
    $(addto).after(newInput); 
    $("#field" + next).attr('data-source',$(addto).attr('data-source')); 
    $("#count").val(next); 
} 

父元素是越來越刪除，但下一個計數器不能正確復位。在隱藏和所有新創建的窗體： -

有人可以幫我請。

感謝

嘗試：

function addFormField(){ 
    var addto = "#field" + next; 
    next = next + 1; 
    var newIn = '<br /><br /><input autocomplete="off" class="span3" id="field' + next + '" name="field' + next + '" type="text" data-provide="typeahead" data-items="8"><button id="b'+next+'" onClick="$(this).prev().remove();$(this).remove();" class="btn btn-info" type="button">-</button>'; 
    var newInput = $(newIn); 
    console.log(addto); 
    $(addto).after(newInput); 
    if(next>1) 
     $("button#b"+next).after(newInput); 
    $("#field" + next).attr('data-source',$(addto).attr('data-source')); 
    $("#count").val(next); 
}
