Grails和Jquery数据报警器
提问于 2016-05-15 06:55:27
我想要写一段代码，允许我创建输入，例如主题、购买日期和资产价值，输入框中有'class =“datepicker‘属性，并且在开始时，所有内容都能正常读取，但是当我调用这些作品在页面中添加其他输入(与上面一样)时，"datepicker”不再给出任何生命迹象。我给你看密码：
<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>

由于输入是动态添加到dom中的，因此在将元素添加到dom后，需要初始化元素的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++
});

因为新元素没有绑定.datepicker()。
而不是：
$('.datepicker').datepicker({
language: 'it'
});用途：
$('body').on('focus',".datepicker", function(){
$(this).datepicker({
language: 'it'
});
