jquery图片上传功能

关于jquery图片上传功能呢，我引入了

jquery.min.jsjquery-1.8.3.min.jsjquery.ui.widget.jsjquery.iframe-transport.jsjquery.fileupload.js

上传图片的代码：

图片上传成功之后，可以选择删除！里面的变量就是我从数据库查出来的，数据库当然存放的是图片的路径了！

上传的js代码：

  $(function (){        var goodsimg = $("#goodsimg").attr("src");        //单张图片显示        if(goodsimg!=""){               $("#goodsimg").css("display","block");               $(".delgoodsimg").css("display","block");        }        //单张图片删除        $(".delgoodsimg").click(function (){              $("input[name='goodsimg']").val("");              $("#goodsimg").css("display","none").attr("src","");              $(this).css("display","none");        });        //多条副        $(".delCertificateimg").live('click',function(){            var delindex = $(this).parents("li").length;            var Certiimgval = $("input[name='Certiimg']").val();            var Certiimgarr = Certiimgval.split("|");            Certiimgarr.pop();            if(Certiimgarr.length == 0){                $("input[name='Certiimg']").val("");            }else{                Certiimgval = Certiimgarr.join("|");                $("input[name='Certiimg']").val(Certiimgval);            }            $(this).parents("li").remove();        });        //jquery图片上传        $('#fileUpload').fileupload({            dataType: 'json',            done: function (e, data)            {                if(data.result.flag == 1 && data.result.img != "")                {                    /*uploadPicCallback(data.result);*/                    $("input[name='goodsimg']").val(data.result.img);                    $("#goodsimg").css("display","block").attr("src",data.result.img);                    $(".delgoodsimg").css("display","block");                }                else                {                    console.log("err");                }            },            progressall: function (e, data)            {                var progress = parseInt(data.loaded / data.total * 100);                $('#uploadPercent').text("加载完成："+progress+"%");            }        });      //多图上传    $('#CertifileUpload').fileupload({        dataType: 'json',        done: function (e, data)        {            if(data.result.flag == 1 && data.result.img != "")            {                if($(".Certidom").find("li").length == 2){                    alert("上传图片多于2张，请删除一张图片后重新上传");                    return false;                }                var certidom = '<li><img src="'+data.result.img+'"  id="Certificateimg" /><a class="delCertificateimg" href="javascript:void(0)"><img src="./images/sign_cacel.png" title="删除" alt="删除"></a></li>';                $(".Certidom").append(certidom);                /*uploadPicCallback(data.result);*/                var Certiimgval = $("input[name='Certiimg']").val();                if(Certiimgval == ""){                    $("input[name='Certiimg']").val(data.result.img);                }else{                    $("input[name='Certiimg']").val(Certiimgval+"|"+data.result.img);                }            }            else            {                console.log("err");            }        },        progressall: function (e, data)        {            var progress = parseInt(data.loaded / data.total * 100);            $('#uploadPercent').text("加载完成："+progress+"%");        }    });    });</script>backend_upload_photo.php文件就是上传图片后台代码处理图片的地址结合上传图片的地方来写此部分$fileExtArr = explode(".",$_FILES['_goodsFile']['name']);$fileExt = ".".$fileExtArr[1];//图片存放地址进行名字随机给处理$path='/backend/actions/upload/'.time().md5($_FILES['_goodsFile']['name'].rand()).$fileExt;move_uploaded_file($_FILES['_goodsFile']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].$path);echo json_encode(array("flag"=>1,"img"=>"..".$path));
