Question

我有多张桌子。表和行是从数据库生成的。顶部的每个表格都有一个复选框，如果我只点击该特定表格，则需要选中复选框。同样明智的我有更多的桌子和支票都应该独立工作每个表。这里我把html放在2个表中。

我的表结构如下：

<table width="800" border="1" cellpadding="2" cellspacing="0" class="inlineTable" style="border-collapse: collapse" bordercolor="#000000">
<tr><td colspan="5" align="center" width="800"><strong>Haweye International&nbsp;(USD)</strong></td></tr>
<tr>
                <th>Sl No</th>
                <th width=130>Tender Description</th>
                <th>Main</th>
                <th><input type="checkbox" id="selecctall"/></th>
                <th title="Selected to Quotation">S2Q</th>
                </tr>
        <tr align='center'><td>1</td><td width='140'>Silicon Free Tape </td><td></td><td><div class='list-item'><input class='checkbox1' type='checkbox' name='member[1]' value='53'></div></td><td title='Selected to Quotation' class="dark"><input type="checkbox" disabled="disabled" name="comparitive[]" value="53"  checked='checked' /></td>
</tr><tr align='center'><td>2</td><td width='140'>UV Sensitive Tape</td><td></td><td><div class='list-item'><input class='checkbox1' type='checkbox' name='member[2]' value='54'></div></td><td title='Selected to Quotation' class="dark"><input type="checkbox" disabled="disabled" name="comparitive[]" value="54"  checked='checked' /></td>
</tr></table>

<table width="800" border="1" cellpadding="2" cellspacing="0" class="inlineTable" style="border-collapse: collapse" bordercolor="#000000">
<tr><td colspan="6" align="center" width="800"><strong>Trend Zone limited&nbsp;(USD)</strong></td></tr>
<tr>
                <th>Sl No</th>
                <th width=130>Tender Description</th>
                <th>Tech %</th>
                <th>Main</th>
                <th><input type="checkbox" id="selecctall"/></th>
                <th title="Selected to Quotation">S2Q</th>
                </tr>
        <tr align='center'><td>1</td><td width='140'>Silicon Free Tape </td><td></td><td></td><td><div class='list-item'><input class='checkbox1' type='checkbox' name='member[3]' value='63'></div></td><td title='Selected to Quotation' class="dark"><input type="checkbox" disabled="disabled" name="comparitive[]" value="63" /></td>
</tr><tr align='center'><td>2</td><td width='140'>UV Sensitive Tape</td><td></td><td></td><td><div class='list-item'><input class='checkbox1' type='checkbox' name='member[4]' value='64'></div></td><td title='Selected to Quotation' class="dark"><input type="checkbox" disabled="disabled" name="comparitive[]" value="64" /></td>
</tr></table>

jquery如下：

$('.selectAll').click(function(e){
  var tr= $(e.target).closest('tr');
  $('td input:checkbox',tr).prop('checked',this.checked);
});

Answer 1

为每个主要复选框提供该复选框类名class="selectAll"，JS将如下所示：

// just in case
// use event delegation here to ensure appended elements
// were bound to this handler
// you can replace `document` with the placeholder
// that dynamic elements inserted with
$(document).on('click','.selectAll', function(e){
  var table= $( this ).closest('table');
  table.find(':checkbox').not( this ).prop('checked',this.checked);
});

Answer 2

id属性应该是唯一的。使用类
使用.not()排除当前元素。
使用:checkbox选择器仅选择type= 'checkbox'元素

＆＃13;

$('.selectAll').change(function() {
  $(this).closest('table').find('.list-item :checkbox').not(this).prop('checked', this.checked);
});
