webuploader的一个页面多个上传按钮实例

借鉴一位大佬的demo  附上他的github地址https://github.com/lishuqi

我把他的cxuploader.js改了不需要预览  直接上传图片后拿到回传地址给img标签显示图片

    jQuery(function() {

        uploader = new Array();//创建 uploader数组
        // 优化retina, 在retina下这个值是2
        var ratio = window.devicePixelRatio || 1,
        // 缩略图大小
        thumbnailWidth = 100 * ratio,
        thumbnailHeight = 100 * ratio,
        supportTransition = (function(){
            var s = document.createElement('p').style,
            r = 'transition' in s ||
                  'WebkitTransition' in s ||
                  'MozTransition' in s ||
                  'msTransition' in s ||
                  'OTransition' in s;
            s = null;
            return r;
        })();
         // 所有文件的进度信息，key为file id
        var percentages = {};
        var state = 'pedding';

        //可行性判断
        if ( !WebUploader.Uploader.support() ) {
            alert( 'Web Uploader 不支持您的浏览器！如果你使用的是IE浏览器，请尝试升级 flash 播放器');
            throw new Error( 'WebUploader does not support the browser you are using.' );
        }

        //循环页面中每个上传域
        $('.uploder-container').each(function(index){

            // 添加的文件数量
            var fileCount = 0;
            // 添加的文件总大小
            var fileSize = 0;

            var filePicker=$(this).find('.filePicker');//上传按钮实例

            //初始化上传实例
            uploader[index] = WebUploader.create({

                formData: {

                }

            uploader[index].on('uploadSuccess',function(file,response){

                 //document.getElementById(response.imageAddr).value=response.fileAdress;
                 $(imageid).attr("src",response.fileAdress);
                alert("上传成功");
            });

            //可以在这里附加额外上传数据

            uploader[index].on('uploadBeforeSend',function(object,data,header) {

                //alert("id:"+filePicker.attr("id"));
                //获得当前id的长度
                var divlen = filePicker.attr("id").length;
                //alert("divlen"+divlen);

    });

删除图片只是隐藏div，不能删服务器

<script type="text/javascript">
/*删除图片  */
function deleteImage(path) {
    //图片名称
    var imageAddrs = mini.get(path).getValue();
    alert(path);
    alert(imageAddrs);

    mini.get(path).setValue("");
    $("#"+path+"_1").attr("src"," ");
    $("#"+path+"_5").hide();
    document.getElementById(path + "_4").style.display = '';
    document.getElementById(path + "_3").style.display = '';
    /*
    硬删除
    if (imageAddrs == ""|| imageAddrs== null|| imageAddrs == undefined) {
        alert("照片为空，请重新操作");
    }else{

        $.ajax({
            type : "POST",
            url : "ajax/removeImage",
            data : {
                imageAddr : imageAddrs
            },
            dataType : "json",
            // 下面三个参数要指定，如果不指定，会报一个JQuery的错误
            success : function(data) {
                console.log(data);
                console.log(data.mess);
                alert(data.mess);
                alert(imageAddrs);
                // 删除成功后刷新页面
                $(".cxuploder").html(page);
                 window.location.reload();
            }
        });
    } */
}
</script>
