【问题描述】：

我想编写一个代码，允许我创建主题、购买日期和资产价值等输入，输入框具有属性“class= “datepicker””，起初一切正常，但当我调用作品追加以在页面中添加其他输入（与上述相同）时，“datepicker”不再给出任何生命迹象。 我给你看代码：

    <div class="well bs-component" ><fieldset><div id="elencoBeni">
        <div class="input-group">
            <span class="input-group-addon">Oggetto</span>
            <g:textField class="form-control" placeholder="Oggetto" name="oggetto" id="oggetto" />
            <span class="input-group-addon"><span class="glyphicon glyphicon-calendar" ></span></span>
            <g:textField class="form-control datepicker" placeholder="Data acquisto" name="dataAcquisto" id="dataAcquisto" />
            <span class="input-group-addon">Valore</span>
            <g:textField class="form-control" placeholder="Valore" name="valoreBene" id="valoreBene"/><br/>
        </div><br/>
    </div>
        <label class="btn btn-success" id="aggiungiOggetto" name="aggiungiOggetto"  >+</label>
    </fieldset></div>

jquery函数：

<g:javascript>
$(document).ready(function()
        $('.datepicker').datepicker(
              language: 'it'
        );    var i = 0;
        $("#aggiungiOggetto").click(function()
            $("#elencoBeni").append('<div class="input-group"><span class="input-group-addon">Oggetto</span><input type="text" class="form-control" placeholder="Oggetto" name="oggetto'+i+'"  id="oggetto'+i+'"/><span class="input-group-addon"><span class="glyphicon glyphicon-calendar" ></span></span><input type="text" class="datepicker form-control" placeholder="Data acquisto" name="dataAcquisto'+i+'" id="dataAcquisto'+i+'"/><span class="input-group-addon">Valore</span><input type="text" class="form-control" placeholder="Valore" name="valoreBene'+i+'" id="valoreBene'+i+'"/><br/></div><br/>');

            i++
        );     </g:javascript>          

【参考方案1】：

由于输入是动态添加到dom的，所以添加到dom后需要为元素初始化datepicker。

$(document).ready(function() 
  $('.datepicker').datepicker(
    language: 'it'
  );
  var i = 0;
  $("#aggiungiOggetto").click(function() 
    $("#elencoBeni").append('<div class="input-group"><span class="input-group-addon">Oggetto</span><input type="text" class="form-control" placeholder="Oggetto" name="oggetto' + i + '"  id="oggetto' + i + '"/><span class="input-group-addon"><span class="glyphicon glyphicon-calendar" ></span></span><input type="text" class="datepicker form-control" placeholder="Data acquisto" name="dataAcquisto' + i + '" id="dataAcquisto' + i + '"/><span class="input-group-addon">Valore</span><input type="text" class="form-control" placeholder="Valore" name="valoreBene' + i + '" id="valoreBene' + i + '"/><br/></div><br/>');

    // initialize datepicker again, which includes the dynamically added element
    $('.datepicker').datepicker(
      language: 'it'
    );

    i++
  );
);

【参考方案2】：

因为新元素没有绑定.datepicker()。

代替：

$('.datepicker').datepicker(
      language: 'it'
);

使用：

$('body').on('focus',".datepicker", function()
    $(this).datepicker(
      language: 'it'
    );
);
