This time I will bring you jquery dynamic operation table rows. What are the precautions for jquery dynamic operation table rows? The following is a practical case, let’s take a look.
The specific code is as follows:
html code:
<p style="width:720px;margin:20px auto;"> <table id="tab11" style="display: none"> <tbody> <tr> <td height="30" align="center"> <input type="text" name="NO" size="2" value="1" /> </td> <td align="center"> <input type="text" name="start_end_time" /> </td> <td align="center"> <input type="text" name="unit_department" /> </td> <td align="center"> <input type="text" name="post" /> </td> <td> <input type="button" id="Button1" onclick="deltr(this)" value="删行" /> </td> </tr> </tbody> </table> <input type="button" id="btn_addtr" value="增行" /> <table id="dynamicTable" width="700" border="0" cellspacing="0" cellpadding="0"> <thead> <tr> <td height="30" align="center" bgcolor="#CCCCCC">ID</td> <td align="center" bgcolor="#CCCCCC">起止时间</td> <td align="center" bgcolor="#CCCCCC">单位/部门</td> <td align="center" bgcolor="#CCCCCC">职位</td> <td></td> </tr> </thead> <tbody> <tr> <td height="30" align="center"> <input type="text" name="NO" size="2" value="1" /> </td> <td align="center"> <input type="text" name="start_end_time" /> </td> <td align="center"> <input type="text" name="unit_department" /> </td> <td align="center"> <input type="text" name="post" /> </td> <td> <input type="button" id="Button2" onclick="deltr(this)" value="删行" /> </td> </tr> </tbody> </table> </p>
js code:
$(function () { var show_count = 20; //要显示的条数 var count = 1; //递增的开始值,这里是你的ID $("#btn_addtr").click(function () { var length = $("#dynamicTable tbody tr").length; //alert(length); if (length < show_count) //点击时候,如果当前的数字小于递增结束的条件 { $("#tab11 tbody tr").clone().appendTo("#dynamicTable tbody"); //在表格后面添加一行 changeIndex();//更新行号 } }); }); function changeIndex() { var i = 1; $("#dynamicTable tbody tr").each(function () { //循环tab tbody下的tr $(this).find("input[name='NO']").val(i++);//更新行号 }); } function deltr(opp) { var length = $("#dynamicTable tbody tr").length; //alert(length); if (length <= 1) { alert("至少保留一行"); } else { $(opp).parent().parent().remove();//移除当前行 changeIndex(); } }
