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 >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！");

}

}
