Adobe Reader X增加书签功能

对于一个阅读软件，特别尤其非常以及十分不理解，Adobe Reader怎么能没有书签功能呢？虽然有一些第三方的pdf阅读器比如Foxit Reader之类的，但懒的折腾的人还是很迷信血统的。可惜Adobe Reader作为一个官方的pdf专用阅读器，以如此庞大的体积，提供了一大堆莫名其妙的十年难得一用的功能，实在让人无语。幸好网上有高人做出了adobe reader的书签js脚本：

// 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() ;

return(s);

items+= '"'+ ii+ ': '+ data[ii][0]+ '"';
}
// assemble the command and the execute it with eval()
var command= 'app.popUpMenu( '+ items+ ' );';

悲剧的是，此脚本经验证，只在 adobe reader8以下有效。若用在adobe reader 10上，则中文菜单项显示为乱码，且此js脚本必须另存为ascii格式才行，存为utf-8等都会无法显示。因此又找了一个专门为10版本修改过的js脚本：

// to be serialized and stored into a persistent
// global string

{
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; )
{

for( jj= 0; jj< 3 && ii< flat.length; ++ii, ++jj )

record.push( flat[ii] );
}
if( record.length== 3 )

}
}
return data;
}
//Get Current Date

测试，可用。且与前一版本兼容。之前版本的书签也可以访问。
