Question

我将一些旧代码从另一个库移动到jQuery，并在此过程中破坏了其他一些代码。我认为jQuery实现其.html函数的方式让我感到悲伤。

以下部分是使用以下语法通过AJAX调用生成函数生成的：$('#status2').html(response);

<!-- Section DivPlaceholders - this is required for ajax call -->
    <span id="status"></span>
    <span id="status2"> 
        <span id="response" class="response"></span>
  <table class="tableBorder">
    <tbody><tr class="row_header thin_border">
   <th class="align_left">Date</th>
 <th class="align_left">From</th>
 <th class="align_left">To</th>    
   <th class="align_left">Activity</th>
 <th class="align_left">P.Code</th>
   <th class="align_left">Del</th>
  <th class="align_left">Edit</th>
 </tr><tr>
  <!-- section: SchedResponse -->
  <tr seq="1" class="row_theme2" id="id3014201105191"></tr>
    <tr><td>20110519</td>
    <td>1330</td>
  <td>1430</td>
  <td>LUNCH</td>  
   <td></td>   

  <td><a onclick="deleteActivity(3014,20110519,1);" href="#"> <img src="img/deleteAction.png"></a></td>
  <td><a onclick="selectEditActivity(&quot;id3014201105191&quot;);" href="#"><img src="img/editAction.png"></a></td>
 </tr>
    </tbody></table>

的Javascript

现在我在var from_date = cells[0].innerHTML;

上收到错误

function selectEditActivity(pass_id){   
    var row = document.getElementById(pass_id), 
    seq = row.getAttribute("seq"), 
    cells = row.getElementsByTagName("td");     
    var from_date   = cells[0].innerHTML;  
    var from_time   = cells[1].innerHTML;  

}

（谢谢保罗）

Answer 1

为什么你也不使用jQuery？试试吧：

function selectEditActivity(pass_id){
    var row = jQuery('#' + pass_id); // Workaround
    seq = row.attr('seq');
    cells = row.find('td');
    var from_date = cells.eq(0).html(); // better .text() I guess
    var from_time = cells.eq(1).html(); // here too
}

修改：代码已修复。感谢@Domenic。

Answer 2

function selectEditActivity(pass_id){   
    var row = $('#'+pass_id); 
    var seq = row.attr('seq');
    var from_date   = $('td', row).eq(0).html();  
    var from_date   = $('td', row).eq(1).html();      
}

转向jquery - 打破了一些JavaScript
