1. jquery file upload 下载
jquery file upload Demo 地址:https://blueimp.github.io/jQuery-File-Upload/
jquery file upload 下载 地址:https://github.com/blueimp/jQuery-File-Upload/tags
jquery file upload API 地址:https://github.com/blueimp/jQuery-File-Upload/wiki/API
2. jquery file upload 样式
使用了bootstrap框架,样式可以参考Demo。

自定义的样式:
- <div class="row fileupload-buttonbar" style="padding-left:15px;">
- <div class="thumbnail col-sm-6">
- <img id="weixin_show" style="height:180px;margin-top:10px;margin-bottom:8px;" src="__PUBLIC__/images/game/game_1.png" data-holder-rendered="true">
- <div class="progress progress-striped active" role="progressbar" aria-valuemin="10" aria-valuemax="100" aria-valuenow="0"><div id="weixin_progress" class="progress-bar progress-bar-success" style="width:0%;"></div></div>
- <div class="caption" align="center">
- <span id="weixin_upload" class="btn btn-primary fileinput-button">
- <span>上传</span>
- <input type="file" id="weixin_image" name="weixin_image" multiple>
- </span>
- <a id="weixin_cancle" href="javascript:void(0)" class="btn btn-warning" role="button" onclick="cancleUpload("weixin")" style="display:none">删除</a>
- </div>
- </div>
- </div>
复制代码
需要引入的js、css文件
- <link href="__PUBLIC__/css/bootstrap.min.css" rel="stylesheet">
- <!-- CSS to style the file input field as button and adjust the Bootstrap progress bars -->
- <link rel="stylesheet" href="__PUBLIC__/css/jquery.fileupload.css">
- <link rel="stylesheet" href="__PUBLIC__/css/jquery.fileupload-ui.css">
- <script src="__PUBLIC__/js/jquery.min.js"></script>
- <script src="__PUBLIC__/js/vendor/jquery.ui.widget.js"></script>
- <script src="__PUBLIC__/js/jquery.fileupload.js"></script>
- <script src="__PUBLIC__/js/jquery.iframe-transport.js"></script>
复制代码
调用方式:
- $(function() {
- $("#weixin_image").fileupload({
- url: "__CONTROLLER__/uploadImg",
- sequentialUploads: true
- }).bind("fileuploadprogress", function (e, data) {
- var progress = parseInt(data.loaded / data.total * 100, 10);
- $("#weixin_progress").css("width",progress + "%");
- $("#weixin_progress").html(progress + "%");
- }).bind("fileuploaddone", function (e, data) {
- $("#weixin_show").attr("src","__PUBLIC__/"+data.result);
- $("#weixin_upload").css({display:"none"});
- $("#weixin_cancle").css({display:""});
- });
-
- });
复制代码
url:后台提交的地址
fileuploadprogress:主要是进度条的修改
fileuploaddone:上传结束后执行的操作
3. 后台执行的代码
使用的thinkphp代码,上传代码很简单
- public function uploadImg(){
- $upload = new \Think\Upload();// 实例化上传类
- $upload->maxSize = 3145728 ;// 设置附件上传大小
- //$upload->exts = array("jpg", "gif", "png", "jpeg");// 设置附件上传类型
- $upload->rootPath = "./Public/Uploads/"; // 设置附件上传根目录
- $upload->savePath = ""; // 设置附件上传(子)目录
-
- // 上传文件
- $info = $upload->uploadOne($_FILES["weixin_image"]);
- if(!$info) {// 上传错误提示错误信息
- //$this->error($upload->getError());
- echo 0;
- }else{// 上传成功 获取上传文件信息
- //$this->display("templateList");
- echo "Uploads/".$info["savepath"].$info["savename"];
- }
- }
