Bootstrap fileinput文件上传预览插件使用详解(2)

callback window=true配置,关闭附件上传的窗口后执行的回调函数(比如更新当前的文件列表),fileIds,oldfileIds两个参数分别是更新后文件ids和更新前的文件ids

BaseFile默认配置,BaseFile的更多实现,请查看BaseFile源码

BaseFile.prototype.default = { winId: "fileWin", width: 900, title: "文件上传", //通用文件上传界面 url: basePath + "/file/uploader", //默认支持多文件上传 multiple: true, //默认弹出附件上传窗口 window:true, showType:"detail", fileinput: { language: 'zh', uploadUrl: basePath + "/file/uploadMultipleFile", deleteUrl:basePath+"/file/delete", uploadAsync:false, validateInitialCount:true, overwriteInitial: false, allowedPreviewTypes: ['image'], previewFileIcon:'<i></i>', previewFileIconSettings: null, slugCallback: function (text) { var newtext=(!text||text=='') ? '' : String(text).replace(/[\-\[\]\/\{}:;#%=\(\)\*\+\?\\\^\$\|<>&"']/g, '_'); //去除空格 return newtext.replace(/(^\s+)|(\s+$)/g,"").replace(/\s/g,""); } } }
