最近经常看一些PDF的电子文档，痛苦的是Adobe Reader竟然没有提供书签的功能，每次看完之后再回到上次看的地方都很麻，到网上一找，还真有人就做了PDF的书签，下载一试效果不错，于是参看了一下Adobe Reader的SDK，修改了一点地方，以更方便的使用,下面是程序的使用方法

1、打开编辑的首选项项

2、确保下面的选项都被选中

3、把下面的代码保存为一个bookmark_page.js文件

// bookmark_page.js, ver. 1.0 // visit: www.pdfhacks.com/bookmark_page/ // edit:cjs 2008-02-17 // 1 修改为中文标签 // 2 设置书签时可以自动获取当前的书名 // 3 自动获取当前所在的页码与总页数,方便查阅 // 4 实现更多功能可以参看Adobe Reader的SDK // use this delimiter for serializing our array var bp_delim= '%#%#'; function SaveData( data ) { // data is an array of arrays that needs // to be serialized and stored into a persistent // global string var ds= '; for( ii= 0; ii< data.length; ++ii ) { for( jj= 0; jj< 3; ++jj ) { if( ii!= 0 || jj!= 0 ) ds+= bp_delim; ds+= data[ii][jj]; } } global.pdf_hacks_js_bookmarks= ds; global.setPersistent( "pdf_hacks_js_bookmarks", true ); } function GetData() { // reverse of SaveData; return an array of arrays if( global.pdf_hacks_js_bookmarks== null ) { return new Array(0); } var flat= global.pdf_hacks_js_bookmarks.split( bp_delim ); var data= new Array(); for( ii= 0; ii< flat.length; ) { var record= new Array(); for( jj= 0; jj< 3 && ii< flat.length; ++ii, ++jj ) { record.push( flat[ii] ); } if( record.length== 3 ) { data.push( record ); } } return data; } //Get Current Date function DateNow(){ var d, s ; d = new Date(); s = d.getFullYear()+"/"; s += (d.getMonth() + 1) + "/"; s += d.getDate() ; /**//* s += d.getHours() + ":"; s += d.getMinutes() + ":"; s += d.getSeconds() ; */ return(s); } function AddBookmark() { // query the user for a name, and then combine it with // the current PDF page to create a record; store this record var thisfilename=this.documentFileName; thisfilename=thisfilename.substr(0,thisfilename.lastIndexOf(".")); var numPlugInss=this.pageNum+1; var currentdate=DateNow(); var label= app.response( "书签名称,可以修改以便于记忆:", "书签名称", "《"+thisfilename+"》第 "+numPlugInss+" 页/共 "+this.numPages+" 页 "+currentdate, false ); if( label!= null ) { var record= new Array(3); record[0]= label; record[1]= this.path; record[2]= this.pageNum; data= GetData(); data.push( record ); SaveData( data ); } } function ShowBookmarks() { // show a pop-up menu; this seems to only work when // a PDF is alreay in the viewer; var data= GetData(); var items= '; for( ii= 0; ii< data.length; ++ii ) { if( ii!= 0 ) items+= ', '; items+= '"'+ ii+ ': '+ data[ii][0]+ '"'; } // assemble the command and the execute it with eval() var command= 'app.popUpMenu( '+ items+ ' );'; var selection= eval( command ); if( selection== null ) { return; // exit } // the user made a selection; parse out its index and use it // to access the bookmark record var index= 0; // toString() converts the String object to a string literal // eval() converts the string literal to a number index= eval( selection.substring( 0, selection.indexOf(':') ).toString() ); if( index< data.length ) { try { // the document must be 'disclosed' for us to have any access // to its properties, so we use these FirstPage NextPage calls // app.openDoc( data[index][1] ); app.execMenuItem( "FirstPage" ); for( ii= 0; ii< data[index][2]; ++ii ) { app.execMenuItem( "NextPage" ); } } catch( ee ) { var response= app.alert("打开书签错误. 是否删除本书签?", 2, 2,"删除书签"); if( response== 4 && index< data.length ) { data.splice( index, 1 ); SaveData( data ); } } } } function DropBookmark() { // modelled after ShowBookmarks() var data= GetData(); var items= '; for( ii= 0; ii< data.length; ++ii ) { if( ii!= 0 ) items+= ', '; items+= '"'+ ii+ ': '+ data[ii][0]+ '"'; } var command= 'app.popUpMenu( '+ items+ ' );'; var selection= eval( command ); if( selection== null ) { return; // exit } var index= 0; index= eval( selection.substring( 0, selection.indexOf(':') ).toString() ); if( index< data.length ) { data.splice( index, 1 ); SaveData( data ); } } function ClearBookmarks() { if( app.alert("确认要清除所有的书签吗?", 2, 2,"删除书签" )== 4 ) { SaveData( new Array(0) ); } } app.addMenuItem( { cName: "-", // menu divider cParent: "View", // append to the View menu cExec: "void(0);" } ); app.addMenuItem( { cName: "设置本页为书签(&B)", cParent: "View", cExec: "AddBookmark();", cEnable: "event.rc= (event.target != null);" } ); app.addMenuItem( { cName: "转到指定书签(&T)", cParent: "View", cExec: "ShowBookmarks();", cEnable: "event.rc= (event.target != null);" } ); //cEnable: "event.rc= true;" } ); app.addMenuItem( { cName: "删除一个书签(&D)", cParent: "View", cExec: "DropBookmark();", cEnable: "event.rc= (event.target != null);" } ); app.addMenuItem( { cName: "清除所有书签(&C)", cParent: "View", cExec: "ClearBookmarks();", cEnable: "event.rc= true;" } );

4、将文件拷贝到D:\Program Files\Reader 9.0\Reader\Javascripts目录下

注：请注意查看自己的版本是否是8.0以上的，不是的话不保证支持。

5、重新打开Adobe Reader，等待10秒，看看下面的图形，相信不用说任何东西，大家都会用了
