node.js实现多图片上传实例

先上效果图：

这是我当时做多图片的代码，拿出来给大家借鉴一下（有些地方需要亲们自己改一下，大方向是对的）

总共涉及到三处文件（常规来说）

1.路由入口文件(我这里是/routes.js,很多时候会在/app.js)

  //添加美食
  app.all('/add',users.add);

2.路由控制器文件（我这里是/routes/users.js）

复制代码代码如下:

//添加美食
exports.add = function (req,res) {
   if (req.method == "GET") {
        var user = {};
     if(req.session.user){
         user = req.session.user;
     }
    res.render("users/food_add",{title:'发布美食-'+config.name,name:config.name,user:user});
} else if (req.method == "POST") {
    //获取数据
    var x = req.body.x;
    var y = req.body.y;
    var cat_id = req.body.cat_id;
    var cat_name = req.body.cat_name;
    var address = req.body.address;
    var title = req.body.title;
    var desc = req.body.desc;
    var content = req.body.content;
    var pics = '';
    var price = req.body.price;
    var tags = req.body.tags;
    var add_time = Date.parse(new Date())/1000;
    var support = 0;
    var uid = req.body.uid;

//处理图片上传
//console.dir(req.files);

                    });
                }
                    }
                });

            });
            }
         });
    }else{
        //没有图片
        //数据
        var data = {
            x:x,//经度
            y:y,//维度
            cat_id:cat_id,//分类id
            cat_name:cat_name,//分类名称
            address:address,//地址
            title:title,//标题
            desc:desc,//简介
            content:content,//内容
            pics:pics,'隔开多张图片
            price:price,//价格
            tags:tags,'隔开多个
            add_time:add_time,//支持度
            support:support,//支持度默认为0
            uid:uid//用户id 可匿名
        };
        food_preDao.insert(data,food) {
            if(err){
                res.json({err:100,content:'数据库错误'});
            }else{
                res.json({err:0,data:food});
            }

});
}

}
};

3.视图文件（我这里是/views/users/food_add.ejs）

复制代码代码如下:

            var name;
            name=path.split('\\');
            var bb=name[name.length-1];
            //alert(bb.substr(0,bb.indexOf('.'))); //AddFile 结果

            $(obj).parent().children().eq(0).css('fontSize','12px');
            $(obj).parent().css('borderStyle','solid');
            $(obj).parent().children().eq(0).html(bb.substr(0,bb.indexOf('.')));
            if($(obj).parent().attr('index')==1){//新增
                var html = '<div class="upload_item" index="1"><span class="upload_item_add" onclick="ADD.upload_click(this)">+</span><input type="file" name="pics" id="pics" class="upload_input" onchange="ADD.upload_change(this)" /></div>';
                $('#upload_box').append(html);
                $(obj).parent().attr('index','0');
            }
        }
     };
</script>
<form method="post" action="/add" enctype="multipart/form-data">
    <table>
        <tr>
            <td>经度：</td><td><input type="text" name="x" id="x" /></td>
        </tr>
        <tr>
            <td>维度：</td><td><input type="text" name="y" id="y" /></td>
        </tr>
        <tr>
            <td>分类：</td><td><select name="cat_id"><option value="1">分类1</option></select></td>
        </tr>
        <tr>
            <td>地址：</td><td><input type="text" name="address" id="address" /></td>
        </tr>
        <tr>
            <td>标题：</td><td><input type="text" name="title" id="title" /></td>
        </tr>
        <tr>
            <td>简介：</td><td><input type="text" name="desc" id="desc" /></td>
        </tr>
        <tr>
            <td>内容：</td><td><input type="text" name="content" id="content" /></td>
        </tr>
        <tr>
            <td>图片：</td><td id="upload_box"><div class="upload_item" index="0" style="display:none;"><span class="upload_item_add" onclick="ADD.upload_click(this)">+</span><input type="file" name="pics" id="pics" class="upload_input" onchange="ADD.upload_change(this)" /></div><div class="upload_item" index="1"><span class="upload_item_add" onclick="ADD.upload_click(this)">+</span><input type="file" name="pics" id="pics" class="upload_input" onchange="ADD.upload_change(this)" /></div></td>
        </tr>
        <tr>
            <td>价格：</td><td><input type="text" name="price" id="price" /></td>
        </tr>
        <tr>
            <td>标签：</td><td><input type="text" name="tags" id="tags" /></td>
        </tr>
        <tr>
            <td colspan="2"><input type="submit" value="提交" /></td>
        </tr>
    </table>
</form>
