代码如下.....迷惘

$(document).ready(function(){
    var options = {
        success:  showResponse,
        dataType: 'json'
    };
    $("#upload-avatar").on("click",function(){
        $('#image').click();
        $('#image').on('change', function(){
            $('#upload').ajaxForm(options).submit();
        });
    });
    $("#uploadavatar").on("click",function(){
        $("#upload-avatar").click();

    });
});

function showResponse(response)  {
    var filename = response.success;
    if(filename == "")
    {
        $("p_goods_img").html("图片上传失败");
        swal("图片上传失败", "", "error");
    } else {
        $("#p_goods_img").html(filename);
        $("#goods_img").val("");
        $("#goods_img").val(filename);
        swal("图片上传成功", "", "success");
    }
}
