Question

我在java中遇到动态数据表的问题。我在一个简单的切换面板中创建了多个动态数据表。生成数据表并正确显示在表单（jsp页面）中。数据也填充在表格中。当我点击表格中的任何命令链接时，它会打开模态面板但不显示任何数据。当我再次刷新页面然后单击命令链接时，模式面板显示数据。

所以问题是第一次数据表生成时我点击任何链接所需的数据永远不会出现在第一个按钮点击的模态面板中。但如果我再回到同一页面，那么所需的数据会出现在modalpanel中。请为我建议解决方案。

我还注意到奇怪的事情是通过比较第一次和第二次加载页面的视图源，数据表名称在第一次出现时没有表单名称，如DATA_TABLE_NAME，第二次数据表名称出现表单名称，例如表格名称：DATA_TABLE_NAME

我一直在复制数据表的日志两次。这是第一次：

首次使用HTML CODE：

<table class="rich-table " id="ST_DATATBL_ID_0" border="0" cellpadding="0" cellspacing="0" width="100%">
<colgroup span="12"></colgroup>
<thead class="rich-table-thead">
<tr class="rich-table-header  ">
<th class="rich-table-headercell " id="ST_DATATBL_ID_0:j_id107" width="20"></th>
<th class="rich-table-headercell " id="ST_DATATBL_ID_0:j_id108" width="2"></th>
<th class="rich-table-headercell " id="ST_DATATBL_ID_0:j_id109">ITEM #<img alt="" class="rich-spacer " height="1" id="ST_DATATBL_ID_0:j_id110" src="/pgsportal/a4j/g/3_3_3.Finalimages/spacer.gif.jsf" width="10%" />
<a href="#" id="ST_DATATBL_ID_0:j_id111" name="ST_DATATBL_ID_0:j_id111" onclick="A4J.AJAX.Submit('scopeItemsForm',event,{'status':'notrequired','similarityGroupingId':'ST_DATATBL_ID_0:j_id111','parameters':{'ST_DATATBL_ID_0:j_id111':'ST_DATATBL_ID_0:j_id111'} ,'containerId':'j_id0'} );return false;">

和第二个timme看起来像：

Answer 1

好像你有身份证问题。

创建标签时，您可以将for属性设置为指向具有相同ID的输入：

<label for="someId">
    <input name="someInput" id="someId"/>
</label>

由于您没有发布任何HTML，因此很难准确说出，但您的标签可能为空for：

<label for="">

或for指向错误的ID：

<label for="someId">
    <input name="someInput" id="someOtherId"/>
</label>
