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 GetData() {
// reverse of SaveData; return an array of arrays
if( global.pdf_hacks_js_bookmarks== null ) {
return new Array(0);
}

//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.\n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C:\Program Files\Adobe\Reader 8.0\Reader\Javascripts目录下

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