jquery动态插入行，不用拼写html，简洁版

这个一个利用jquery实现动态插入输入行效果小功能，不用在javascript里拼写html字符串，更简洁、高效。

html代码：

<div class="fitem">
<table id="tblData">
<tr>
<td>保证人姓名</td>
<td>证件号码</td>
<td>工作单位</td>
<td>职务</td>
<td>联系电话</td>
<td>婚姻状况</td>
<td>家庭地址</td>
<td>月收入情况</td>
<td>资产总额</td>
<td>负债总额</td>
</tr>
<tr id="tRow0">
<td>
<input id="guaranterName" name="guaranterName" style="width:89px">
</td>
<td>
<input id="guaranterCard" name="guaranterCard" style="width:89px">
</td>
<td>
<input id="guaranterEmployer" name="guaranterEmployer" style="width:89px">
</td>
<td>
<input id="guaranterDuties" name="guaranterDuties" style="width:89px">
</td>
<td>
<input id="guaranterPhone" name="guaranterPhone" style="width:89px">
</td>
<td>
<select id="guaranterMaritalStatus" name="guaranterMaritalStatus" style="width:89px">
<option value=""></option>
<option value="已婚">已婚</option>
<option value="未婚">未婚</option>
<option value="离异">离异</option>
<option value="丧偶">丧偶</option>
<option value="其他">其他</option>
</select>
</td>
<td>
<input id="guaranterHouseAddress" name="guaranterHouseAddress" style="width:89px">
</td>
<td>
<input id="guaranterMonthlyIncome" name="guaranterMonthlyIncome" style="width:89px">
</td>
<td>
<input id="guaranterValues" name="guaranterValues" style="width:89px">
</td>
<td>
<input id="guaranterTotalLiabilities" name="guaranterTotalLiabilities" style="width:89px">
</td>
</tr>
</table>
<br />
<div style="text-align:center;">
<a href="#" onclick="addGuaranterRow()">添加一行</a>
</div>

</div>

 

javascript代码：

//添加行
function addGuaranterRow(){
var num=$("#guaranterRowCount").val();
num=parseInt(num);
num++;//点击自加
var str='<td><a href="#" onclick=delGuaranterRow('+num+')>删除</a></td>';
$("#tRow0").clone(true).attr("id","tRow"+num).appendTo("#tblData");
$("#tRow"+num+"td").each(function(){
$(this).find("input[type='text']").val("");//清空数据
$(this).find("input[name='guaranterName']").attr("id","guaranterName"+num).attr("name","guaranterName"+num);
$(this).find("input[name='guaranterCard']").attr("id","guaranterCard"+num).attr("name","guaranterCard"+num);
$(this).find("input[name='guaranterEmployer']").attr("id","guaranterEmployer"+num).attr("name","guaranterEmployer"+num);
$(this).find("input[name='guaranterDuties']").attr("id","guaranterDuties"+num).attr("name","guaranterDuties"+num);
$(this).find("input[name='guaranterPhone']").attr("id","guaranterPhone"+num).attr("name","guaranterPhone"+num);
$(this).find("input[name='guaranterMaritalStatus']").attr("id","guaranterMaritalStatus"+num).attr("name","guaranterMaritalStatus"+num);
$(this).find("input[name='guaranterHouseAddress']").attr("id","guaranterHouseAddress"+num).attr("name","guaranterHouseAddress"+num);
$(this).find("input[name='guaranterMonthlyIncome']").attr("id","guaranterMonthlyIncome"+num).attr("name","guaranterMonthlyIncome"+num);
$(this).find("input[name='guaranterValues']").attr("id","guaranterValues"+num).attr("name","guaranterValues"+num);
$(this).find("input[name='guaranterTotalLiabilities']").attr("id","guaranterTotalLiabilities"+num).attr("name","guaranterTotalLiabilities"+num);
});
$("#guaranterRowCount").val(num);//重新赋值
$("#tRow"+num).append(str);
}
//删除行
function delGuaranterRow(rowIndex){
var num=$("#guaranterRowCount").val();
num=parseInt(num);
if(rowIndex>0&&num>0){//判断是不是第一行
$("#tRow"+rowIndex).remove();
num--;//删除后要自减
$('#guaranterRowCount').val(num);
}else{
alert("这是第一行了！");
}
}
