SNF Rapid Development Platform 3.0--File batch upload-Unified Attachment Manager-Online Preview file (with Internet and no two)

In fact, the use of attachment management in SNF is a very simple thing, a code can be done. But I also want to record here the requirements that the unified Attachment Manager can meet.

    1. Generic attachment management, do not repeat the development, call as concise as possible.
    2. Batch file upload, and limit for each file size, client no refresh
    3. You can change the name of the uploaded attachment to a more friendly name.
    4. Files that have already been uploaded can be deleted.
    5. and record the file size, the descendants, time and modify people and time and so on.
    6. You can download attachments to your local computer.
    7. Online preview of files, support for previewing without Office software (whether it's a picture or Office document that supports previews)

Although more than the professional graphics and document management system functions, but for most enterprises is enough, and easy to use.

Here's a look at the effect and how it's implemented:

The first step is to add a button to the page:

To configure a button event:

 //Attachment Manager     This. Attachmentsclick =function () {varrow = Self.grid.datagrid ('getselected'); if(!row)returnSnf.message ('Warning','Please select a character first! '); Snf. Attachments (row. Realname, row._id,"SYS","Sys-role"); }

Unified method for Button event invocation:

/** * Add Unified attachment Management * * @author Wang Jindou 2015-1-31 **/SNF. Attachments=function (title, Businessid, Businessmodule, Attachmenttype) {Snf.dialog ({title:"("+ title +"-Role) attachment management", Width: -, Height:550, Iconcls:'Icon-attach', maximizable:true, HTML:'<iframe id= "_view_attachmentsclick_" scrolling= "Auto" style= "width:100%;height:100%;" ></iframe>', Viewmodel:function (w) {W.find ("iframe"). attr ("src","/attachments/index/"+ Businessid +"/"+ Businessmodule +"/"+Attachmenttype); }    });};

The effect of running:

Attachments No Refresh bulk upload

Name modification and deletion of attachments

Accessories preview:

Integrated online and local generate files Two preview way, is to have the Internet users better experience and non-connected users can also view. And you do not need to install Office locally and on the server side.

    1. Use Microsoft's platform for Office documents to be viewed online, with good results but with the Internet.

2. View Office files after generating HTML files
