javascript - Grails 和 Jquery 日期选择器

Question

我想编写一个代码，允许我创建输入，例如主题、购买日期和 Assets 值(value)，输入框具有属性“class =“datepicker””，起初一切正常读取，但是当我调用 works to append 以在页面内添加其他输入(与上面相同)时，“datepicker”不再显示任何生命迹象。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>

由于input是动态添加到dom中的，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++
  });
});
