【转】自己写脚本给PDF文件加书签

在用PDF阅读文件时，如果页数过多，我们一时无法看完，或者是某一页面需要保存记录，就需要用到书签功能，以便于下次查阅。而普通的PDF（相对于不是高级的版本）是没有书签功能的。那么如何增加书签功能呢？我在网上找到了下面这段代码，经验证可以实现哈~希望对大家有用！

// 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;" } );

将以上代码存为bookmark_page.js，放入D:\Program Files\Adobe\Reader 8.0\Reader\Javascripts目录下，然后重启reader。
