图片上传-蒲公英云

图片上传

文件上传流程：
1、定义

2、点击上传区域，触发打开选择框：

$(“#uploader”).click(function(){
$(“.upload”).click(); // 打开文件选择窗口，若点击会直接打开，则无需此代码
});

3、后台处理上传至图片服务器，返回图片地址，显示

4、获取图片路径，保存路径到数据库

function uploadimage(fileThis){
    var fileObj = $(fileThis)[0].files[0];
    var type = $(fileThis).data("type")
    if (typeof (fileObj) == "undefined" || fileObj.size <= 0) {
        return;
    }
    var formFile = new FormData();
    formFile.append("upfile", fileObj); //加入文件对象
    formFile.append("type", type); //加入文件对象
    var action = basePath+"/user/platformInfo/uploadImage";
    $.ajax({
        url: action,
        data: formFile,
        type: "Post",
        cache: false,//上传文件无需缓存
        processData: false, 告诉jQuery不要去处理发送的数据
        contentType: false, //告诉jQuery不要去设置Content-Type请求头
        success: function (data) {
            if(data.code == "88"){  // 图片显示处理
                //$(fileThis).parents(".activsx").css({"background":"red"});
                var $activsx = $(fileThis).parents(".activsx");
                $($activsx).find(".del").css("display", "block"); // 显示删除样式
                $($activsx).find(".pic ").attr("src", data.data); // 将图片路径存入src中，显示出图片
                $($activsx).find(".pid").attr("src", data.data);
            }else{
                alert(data.message);
            }
        }
    })
}

<img id='pImg' src='"+data.data+"'/>
var logo = $("#pImg").attr("src");   // 这样获取图片路径更有效
