$("#imgUpload").fileinput({
    language: 'zh',
    //showCaption: false,
    //showPreview: true,
    showClose: false,
    browseClass: "btn btn-info",
    uploadUrl: createUrl('/ueditor/upload'),
    maxFileSize: 1000,
    maxFilesNum: 10,

var imgs = [];
$("#imgUpload").on("fileuploaded", function(event,data,previewId,index){  
    var img = {
        id: previewId,
        name: data.response.url
    };
    imgs.push(img);
});
$("#imgUpload").on("filesuccessremove", function(event,data,previewId,index){  
    for(var i=0; i<imgs.length; i++){
        if(data == imgs[i].id){
            imgs.splice(i, 1);
        }
    }
    if(imgs.length == 0){
        $("#imgUpload").fileinput('clear'); //避免一张张删除完后预览框变小
    }

});

注： 上传成功后再删除图片，发现data是以uploaded-开头的，而数组中存的都是以preview-开头的，修改代码如下：

//if (file !== undefined) {
    newstack[i] = file;
    newnames[i] = self._getFileName(file);
    $thumb.attr({
        'id': self.previewInitId + '-' + i,
        'data-fileindex': i
    });
    i++;
/*} else {
    $thumb.attr({
        'id': 'uploaded-' + uniqId(),
        'data-fileindex': '-1'
    });
}*/
