两种表格之间的tabindex不起作用

我有两种形式 . 第一种形式 search 和 insert .

但是在按下搜索表单中的按钮后，tabindex不会转到insetform中的第一个输入 .

请注意，在搜索表单中有一个隐藏的div幻灯片切换，在按钮之后，下一个选项卡将会转到那里 .

<form id="searchform" name="searchform" method="get" role="form" tabindex="1">
        <table>
            <tr>
                <td colspan="6"> &nbsp; </td>
            </tr>
            <tr>
                <td><input tabindex="1" id="name" placeholder="name" name="name" type="text"></td>
                <td><input tabindex="2" id="company" placeholder="company" name="company" type="text"></td>
                <td><input tabindex="3" id="persona" placeholder="persona" name="persona" type="text"></td>
                <td><input tabindex="4" id="website" placeholder="website" name="website" type="text"></td>
                <td> <a href="#" tabindex="5" class="btn btn-positive" id="searchlead"> Search </a></td>
                <td> <a style="margin-right: 6px;" href="#"  tabindex="6" class="btn btn-info" id="insert"> Insert </a></td>
            </tr>
            <tr class="slideTogglerow" style="display: none;">
                <td><div> 
                    From my list <input type="checkbox" name="search_own_list"  style="margin: 8px;" id="search-own-list"/>
                    </div>
                </td>
                <td> <input type="text" name="date_inserted" placeholder="date" id="date_inserted"/></td>
            </tr>
            <tr>
                <td>
                    <a id="advancesearch" href="#">
                    Advanced Search
                    <img src="assets/img/add-button.png"/> 
                    </a> 
                </td>
                <td colspan="5">  </td>
            </tr>
        </table>
    </form>
