您好我正在尝试添加新表单字段并在获得本教程的启发后删除表单字段 - http://bootsnipp.com/snipps/dynamic-form-fields

我当前的问题是按时间顺序删除和重置所有值。

<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>

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);  
}

父元素被删除,但下一个计数器未正确重置。隐藏的和所有新创建的形式: -

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);  
}
