Adobe Reader X添加Javascripts 书签的方法

1.配置Adobe Reader X

编辑--首选项--因特网  选项要都被选中

 

2.把下面代码存为bookmark_page.js文件

--------------------------------------------------------------------------------------------------------

// bookmark_page.js, ver. 1.0

// visit:

 

// 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;

}

 

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 label= 

    app.response( "Bookmark Name:",

                  "Bookmark Name",

                  "",

                  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("Error trying to open the requested document.\nShould I remove this bookmark?", 2, 2);

      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("Are you sure you want to erase all bookmarks?", 2, 2 )== 4 ) {

    SaveData( new Array(0) );

  }

}

 

app.addMenuItem( {

cName: "-",              // menu divider

cParent: "View",         // append to the View menu

cExec: "void(0);" } );

 

app.addMenuItem( {

cName: "Bookmark This Page &B",

cParent: "View",

cExec: "AddBookmark();",

cEnable: "event.rc= (event.target != null);" } );

 

app.addMenuItem( {

cName: "Go To Bookmark     &T",

cParent: "View",

cExec: "ShowBookmarks();",

cEnable: "event.rc= (event.target != null);" } );

 

app.addMenuItem( {

cName: "Remove a Bookmark  &D",

cParent: "View",

cExec: "DropBookmark();",

cEnable: "event.rc= (event.target != null);" } );

 

app.addMenuItem( {

cName: "Clear Bookmarks    &C",

cParent: "View",

cExec: "ClearBookmarks();",

cEnable: "event.rc= true;" } );

------------------------------------------------------------------------------------------------------

最后把bookmark_page.js文件放到安装adobe reader的文件夹Reader\Javascripts目录下;

重新打开adobe reader就会在视图工具栏里出现书签相关选项。


另外,下面的地址中有bookmark_page.js文件的压缩包
