jQuery的动态添加表格字段，删除表格字段

Question

你好我试图从本教程中得到启发后添加新的表单字段和删除表单字段 - http://bootsnipp.com/snipps/dynamic-form-fields

我目前的问题是删除并重新设置所有的值按时间顺序排列。

<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); 
} 

父元素是越来越删除，但下一个计数器不能正确复位。在隐藏和所有新创建的窗体： -

尝试：

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); 
}
