在创建具有非常酷选项的表格单元格时，我需要采取两个步骤。首先，我创建表格单元格作为JavaScript中的所有'正常'功能的DOM对象，就像它是一个复选框，一个选择，一个输入，一个链接等。 然后我需要把表格放在页面上做下一步，我认为jqueryui的自动完成和日期选择等高级功能。有这些下降的用户真棒。在元素呈现之前设置jqueryui
我确实有这个工作，但是，我确实需要打两个电话。首先创建TableCell，然后渲染，然后我需要再次调用postRenderTableFunctions以获取自动完成功能。所以问题是，为什么第二次调用，jqueryui不会在第一次调用时起作用。您可以在输入创建中看到注释部分，我试图让自动完成工作。

cell.appendChild(element);
$('#' + element.id).datepicker(

dateFormat: 'yy-mm-dd',
onSelect: function()
{
$(this).focus();

onClose: function (dateText, inst)

$(this).select();

我怀疑我可能会工作，如果您替换'$（“＃”+ name）.autocomplete（{'with'$（element）.autocomplete（{'虽然我目前没有测试它的方法 –
John看来你是对的，你能帮我理解为什么吗？ – Iannazzi
