我在html文档的底部有下面的jQuery代码。我的目的是根据下面的html代码在最后一列之后添加一列。使用jQuery在最后一列之后添加列
tbody(id =“output”)是作为jsp文件的输出生成的。我已经在JSFIDDLE上测试过它,它工作正常,但我无法让它在我的html页面上工作。任何人有想法?
<script>
$('document').ready(function() {
var tr = $('#table tbody tr');
var td = '<td><button>Reserve</button></td>';
tr.each(function() {
$(td).insertAfter($(this).find('td').eq(3));
});
});
</script>
HTML
<table id="table" class="table table-hover">
<thead>
<tr>
<th width="15%"><b>Course Code</b>
</th>
<th width="25%"><b>Course Description</b>
</th>
<th width="35%"><b>Available Schedule</b>
</th>
<th width="10%"><b>Reservations</b>
</th>
<th width="15%"></th>
</tr>
</thead>
<tbody id="output">
<tr>
<td>ME101</td>
<td>Marine Engineering 101</td>
<td>June 1 - August 30, 2014</td>
<td>56</td>
</tr>
<tr>
<td>ME102</td>
<td>Marine Engineering 102</td>
<td>June 1 - August 30, 2014</td>
<td>32</td>
</tr>
<tr>
<td>ME201</td>
<td>Marine Engineering 201</td>
<td>June 1 - August 30, 2014</td>
<td>54</td>
</tr>
<tr>
<td>ME202</td>
<td>Marine Engineering 202</td>
<td>June 1 - August 30, 2014</td>
<td>47</td>
</tr>
<tr>
<td>CS101</td>
<td>Certificate in Seamanship 101</td>
<td>June 1 - August 30, 2014</td>
<td>12</td>
</tr>
</tbody>
</table>

这是餐桌上的全功能HTML结构。请注意,“loadJSP”函数生成tbody行的html输出。
<div class="col-md-12 well setup-content" id="step-2">
<h1 class="text-center">STEP 2</h1>
<p>Select the schedule you wish to attend by clicking the check button on the rightmost column.</p>
<hr class="colorgraph">
<form id="reservation2" name="reservation2" class="form-horizontal" role="form" method="post" action="#">
<div class="table-responsive">
<table id="table" class="table table-hover">
<thead>
<tr>
<th width="15%"><b>Course Code</b>
</th>
<th width="25%"><b>Course Description</b>
</th>
<th width="35%"><b>Available Schedule</b>
</th>
<th width="10%"><b>Reservations</b>
</th>
<th width="15%"></th>
</tr>
</thead>
<tbody id="output">
<!-- Data output from JSP will be displayed here. -->
<script>
loadJSP("pntc_fetchschedules.jsp");
</script>
</tbody>
</table>
</div>
<hr class="colorgraph">
<div class="control-group text-center">
<button id="activate-step-3" class="btn btn-primary btn-lg" tabindex="17">Proceed to Step 3</button>
</div>
</form>
</div>
UPDATE
它终于奏效。正如Rajaprabhu所建议的,问题在于文件pntc_fetchschedules.jsp
。看来jQuery无法看到jsp文件的输出。作为一个修复,我把jquery脚本放在pntc_schedules.jsp
里面,尽管我的目的是在jsp生成它们之后改变html列(也就是说,不用接触jsp文件本身)。
如果有人根据我的意图有更好的解决方案,我会非常感激。
谢谢Rajaprabhu的帮助!
做你检查控制台????? –
