用jquery给li添加id同时添加img

$(function(){

$("li").each(function(index){

$(this).attr("id","skin"+(index+1)).html('<img src="pic/skin_'+(index+1)+'.jpg"/>')

//或者可以这样 var img=$("img").attr("src","pic/skin_'+(index+1)+'.jpg") $(this).attr("id","skin"+(index+1)).append(img)

})

})

<script type="text/javascript">

function jion1() {

var img = document.getElementById("dd")//dd为img的id img的src为空值

var img1 = img.setAttribute("src", "images/psd_34.gif")

}

</script>

var index = 0// index为0-4

$("hotorder ol li

").eq(index).find("p a").append($("<img src='address.jpg' />"))

这样应该可行
