发布时间：2020-12-13 21:32:57 所属栏目：PHP教程来源：网络整理

导读：一、在TP框架中使用切片上传（1）.HTML页面的内容 head link href ="/webuploader/webuploader.css" rel ="stylesheet" / head body div id ="uploader" class ="wu-example" !-- 用来存放文件信息 -- div id ="thelist" class ="uploader-list" / div div

一、在TP框架中使用切片上传

（1）.HTML页面的内容

<head>
<link href="/webuploader/webuploader.css" rel="stylesheet">
</head>
<body>
<div id="uploader" class="wu-example">
    <!--用来存放文件信息-->
    <div id="thelist" class="uploader-list"></div>
    <div class="btns">
        <div id="picker">选择文件</div>
        <button id="ctlBtn" class="btn btn-default">开始上传    
       </button>
       </div>
</div>
<script type="text/javascript" src="/webuploader/webuploader.js"></script>
<script type="text/javascript">
var $btn = $(‘#ctlBtn‘);
var uploader = WebUploader.create({

    // swf文件路径
    swf: ‘/webuploader/Uploader.swf‘,// 文件接收服务端。
    server: ‘uploadFile‘,// 选择文件的按钮。可选。
    // 内部根据当前运行是创建，可能是input元素，也可能是flash.
    pick: ‘#picker‘,chunked: true,//是否要分片处理大文件上传
    chunkSize:2*1024*1024,//分片上传，每片2M，默认是5M
    fileSingleSizeLimit: 10*1024* 1024 * 1024,// 不压缩image,默认如果是jpeg，文件上传前会压缩一把再上传！
    resize: false
});
// 当有文件被添加进队列的时候
uploader.on( ‘fileQueued‘,function( file ) {
    var $list = $(‘#thelist‘);
    $list.append( ‘<div id="‘ + file.id + ‘" class="item">‘ +
        ‘<h4 class="info">‘ + file.name + ‘</h4>‘ +
        ‘<p class="state">等待上传...</p>‘ +
    ‘</div>‘ );
});
// 文件上传过程中创建进度条实时显示。
uploader.on( ‘uploadProgress‘,function( file,percentage ) {
    var $li = $( ‘#‘+file.id ),$percent = $li.find(‘.progress .progress-bar‘);

    // 避免重复创建
    if ( !$percent.length ) {
        $percent = $(‘<div class="progress progress-striped active">‘ +
          ‘<div class="progress-bar" role="progressbar" style="width: 0%">‘ +
          ‘</div>‘ +
        ‘</div>‘).appendTo( $li ).find(‘.progress-bar‘);
    }

    $li.find(‘p.state‘).text(‘上传中‘);

    $percent.css( ‘width‘,percentage * 100 + ‘%‘ );
});
uploader.on( ‘uploadSuccess‘,function( file ) {
    $( ‘#‘+file.id ).find(‘p.state‘).text(‘已上传‘);
});

uploader.on( ‘uploadError‘,function( file ) {
    $( ‘#‘+file.id ).find(‘p.state‘).text(‘上传出错‘);
});

uploader.on( ‘uploadComplete‘,function( file ) {
    $( ‘#‘+file.id ).find(‘.progress‘).fadeOut();
});

$btn.on(‘click‘,function(){
    if ($(this).hasClass(‘disabled‘)) {
        return false;
    }
    uploader.upload();
});
</script>
</body>

二、在CI框架中使用切片上传

（1）.这里直接写控制器里面的方法

public function uploadFile(){
        header("Access-Control-Allow-origin:*");
        //header("Access-Control-Allow-Credentials:true");
        //header(‘Access-Control-Allow-Headers:x-requested-with,content-type‘);

        // Support CORS
        // header("Access-Control-Allow-Origin: *");
