This time I will bring you how to use jquery to operate tables efficiently. What are the precautions for using jquery to operate tables efficiently? The following is a practical case, let’s take a look.

Use jquery to add a row and delete a row to the specified table

<script language="
javascript
" src="./jquery.js"></script>
<table border="1px #ooo" id="test" name="test" class="test" cellpadding="0" cellspacing="0" width="20%">
<tr id="1"><td width="30%">1</td>
<td width="30%">2</td>
<td width="30%">3</td></tr>
<tr id="2"><td width="30%">11</td>
<td width="30%">22</td>
<td width="30%">33</td></tr>
</table>
<table border="1px #ooo" id="test1" name="test1" cellpadding="0" cellspacing="0" width="20%"> <tr id="4"><td width="30%">1</td>
<td width="30%">2</td>
<td width="30%">3</td>
</tr>
</table>
<input type="button" name="button" value="add" onclick="addtr(&#39;test&#39;);">
<input type="button" name="button" value="del" onclick="deltr(&#39;test&#39;);">
<script> //在id为test的table的最后增加一行
function addtr(id){ tr_id = $("#test>tbody>tr:last").attr("id");
tr_id++; //alert(tr_id);
str = "<tr id = &#39;"+tr_id+"&#39;><td width=&#39;30%&#39;>re1</td><td width=&#39;30%&#39;>re2</td><td width=&#39;30%&#39;>re3</td></tr>";
$(&#39;#&#39;+id).append(str); } //删除id为test的table的最后一行
function deltr(id){ tr_id = $("#test>tbody>tr:last").attr("id"); $(&#39;#&#39;+tr_id).remove();
}
</script>

jQuery dynamically adds and deletes rows and columns of the table

var tableHtml = $("#testTable tbody").html();
tableHtml += rowTemplate; $("#testTable tbody").html(tableHtml); }
  function delRow(_id){ $("#testTable .tr_"+_id).hide(); rowCount--; }  
function addCol(){ colCount++; $("#testTable tr").each(function(){  
var trHtml = $(this).html(); trHtml += &#39;<td onclick="delCol(&#39;+colCount+&#39;)">增加的td</td>&#39;;
$(this).html(trHtml);
});  
}  
function delCol(_id){   $("#testTable tr").each(function(){ $("td:eq("+_id+")",this).hide(); });
colCount--;
}  
function mover(_id){ $("#testTable tr:not(:first)").each(function(){ $("td:eq("+_id+")",this).removeClass("cl1");
$("td:eq("+_id+")",this).addClass("cl2"); }); }  
function mout(_id){ $("#testTable tr:not(:first)").each(function(){ $("td:eq("+_id+")",this).removeClass("cl2");
$("td:eq("+_id+")",this).addClass("cl1"); }); } </script>

jquery operates the table (add/delete rows, add /Delete column)
