jquery问题，请高手指点，是否应用回调还是哪里有错啊

Answer 1

$(".sub1 .pic ul li img").click(function(){
        var imgurl,index=$(this).index();
        $(".sub1_1").show();//好友选择层
        $(".sub1_1 .agree").click(function(){//点击确定选中一个好友
            var friend_inp = $(".friends input[type='radio']:checked").eq(0).value,  
            userinfo = friend_inp.split('|*|'),
            imgurl=userinfo[2];
            $(".sub1_1").hide();
            $(".sub1 .pic ul li img").eq(index).attr("src",imgurl); 
        })
})
这样？？不知道你的DOM结构。不确定是否能行但你的用法可以与我上面写的做个参考

Answer 3

您的方法，总是显示在第一个的li img上如何能在选中的那img替换掉选择的好友头像

Answer 4

我上面写的方法，是直接应用的。外面没有
$(".sub1 .pic ul li img").each(function(n){//
}这个的，你是这么测试的么？

Answer 5

消息: 'undefined' 为空或不是对象
出现了一个错误

Answer 6

$(".sub1 .pic ul li img").click(function(){
        var imgurl,index=$(this).index();
alert(index);
        $(".sub1_1").show();//好友选择层
        $(".sub1_1 .agree").click(function(){//点击确定选中一个好友
             alert(index);
var friend_inp = $(".friends input[type='radio']:checked").eq(0).value,  
            userinfo = friend_inp.split('|*|'),
            imgurl=userinfo[2];
            $(".sub1_1").hide();

            $(".sub1 .pic ul li img").eq(index).attr("src",imgurl); 
        })
})
我不管在里还是外alert(index)得到的值全是0

Answer 7

如果下面的效果不是你需要的，就参考做你自己的业务逻辑修改吧
<script type="text/javascript">
$(function(){
    $(".sub1 .pic ul li img").click(function(e){
        var imgurl,index=$(this).parent().index(),_that=$(this);
        $(".sub1_1").show();//好友选择层
        $(".sub1 .pic ul li img").removeAttr("me");
        $(this).attr("me","1");
    });
    $(".sub1_1 .agree").click(function(e){//点击确定选中一个好友
        var friend_inp = $(".friends input[type='radio']:checked").val(),  
        userinfo = friend_inp.split('|*|'),
        imgurl=userinfo[2];
        $(".sub1_1").hide();
        $(".sub1 .pic ul li img[me='1']").attr("src",imgurl);
    });
})
</script>
