首先需要下载好对应的压缩包,下载地址:https://github.com/kartik-v/bootstrap-fileinput

本人只是简单实用,更多详细的可以再研究一下

头部引用

    <head>
        <meta charset="UTF-8"/>

        <link href="./css/bootstrap.min.css" rel="stylesheet">
        <script src="./js/jquery-2.0.3.min.js"></script>
        <script src="./js/bootstrap.min.js" type="text/javascript"></script>

        <link href="./css/fileinput.css" media="all" rel="stylesheet" type="text/css" />
        <script src="./js/fileinput.js" type="text/javascript"></script>
        <script src="./js/fileinput_locale_zh.js" type="text/javascript"></script>

    </head>

上三个是必定的因为使用的是bootstrap,下面三个是控件的链接,最好一个是中文的汉化,这就是头部的内容!

表单代码

            <form action="2.php" enctype="multipart/form-data" method="post">
                <input id="imgUpload" class="file" name="thumb" type="file" multiple data-min-file-count="1">
                <br>
                <button type="submit" class="btn btn-primary">提交</button>
                  <button type="reset" class="btn btn-default">重置</button>
            </form>


初始化设置Script代码,这是常见的设置

$("#uploadfile").fileinput({

                language: 'zh', //设置语言

                uploadUrl:"http://127.0.0.1/testDemo/fileupload/upload.do", //上传的地址

               allowedFileExtensions: ['jpg', 'gif', 'png'],//接收的文件后缀

               //uploadExtraData:{"id": 1, "fileName":'123.mp3'},

                uploadAsync: true, //默认异步上传

                showUpload:true, //是否显示上传按钮

                showRemove :true, //显示移除按钮

                showPreview :true, //是否显示预览

                showCaption:false,//是否显示标题

                browseClass:"btn btn-primary", //按钮样式    

               dropZoneEnabled: false,//是否显示拖拽区域

               //minImageWidth: 50, //图片的最小宽度

               //minImageHeight: 50,//图片的最小高度

               //maxImageWidth: 1000,//图片的最大宽度

               //maxImageHeight: 1000,//图片的最大高度

                //maxFileSize:0,//单位为kb,如果为0表示不限制文件大小

               //minFileCount: 0,

                maxFileCount:10, //表示允许同时上传的最大文件个数

                enctype:'multipart/form-data',

               validateInitialCount:true,

                previewFileIcon: "<iclass='glyphicon glyphicon-king'></i>",

               msgFilesTooMany: "选择上传的文件数量({n}) 超过允许的最大数值{m}!",

           }).on("fileuploaded", function (event, data, previewId, index){

          //返回判断操作       

});

实我的实例应用

$("#imgUpload").fileinput({
        language: 'zh',
        uploadUrl: "/admin.php?a=ajaxuploadimage",
        dropZoneEnabled: false,
        autoReplace: true,
        maxFileCount: 1,
        allowedFileExtensions: ["jpg","jpeg", "png", "gif"],
        browseClass: "btn btn-primary", //按钮样式 
        previewFileIcon: "<i class='glyphicon glyphicon-king'></i>"
        })
    .on("fileuploaded", function (e, data) {
        var res = data.response;
        if (res.state > 0) {
            //异步上传,返回来的值添加到隐藏的input里面提交上去一起处理
             $("#file_upload_image").attr('value',res.path);
            alert(res.msg+'上传成功');
            //上传后路径
            // alert(res.path);
        }
        else {
            alert(res.msg+'上传失败')
        }
    })
</script>

异步地址,返回输出json信息

public function ajaxuploadimage() {
		$upload = D("UploadImage");
      //图片
		$res = $upload->imageUpload();
		if ($res === false || !is_array($res)) {
			echo json_encode( $result = array(
                  'state' => 0 ,
                  'msg'=>$res['msg'] 
                  ) );
		}else{
			echo json_encode( $result = array(
            'state' => 1, 
            'msg'=>$res['msg'], 
            'path'=>$res['res']) );
		}
	}

imageUpload方法,使用的Thinkphp文件上传,自己写文件上传方法也可以!

private $_uploadObj = '';
private $_uploadImageData = '';

const UPLOAD = 'upload';
public function __construct() {
	$this->_uploadObj = new \Think\Upload();
	$this->_uploadObj->rootPath = './'.self::UPLOAD.'/';
	$this->_uploadObj->subName = 'temp';
}

public function imageUpload(){
	$res = $this->_uploadObj->upload();

	if ($res) {
		return $res = array( 'res' =>$imgpath, 'msg' =>'附带信息' );
	}else{
		return false;
	}
}
