求助
下面是一个网文提取软件中的一个HTML, 它是通过在IE选择文字,然后通过IE菜单,打开此HTML, 然后得到文字以及链接, 然后调用一个自写的Open7Txt.dll,实现将内容发送到它的程序中.. 我对javascript太弱了..谁能帮我改改,需要实现的功能: 将选择的文字,以及里面包含的链接, 放至到变量xxxstr中就行..
<script language="javascript">
var userURL=external.menuArguments.location.href;
var docbody=external.menuArguments.document;
var linksbody;
linksbody=docbody.selection.createRange().htmlText;
if(linksbody=='')
linksbody=getlinkbody();
//alert(linksbody);
var _7txtObj = new ActiveXObject("Open7Txt.Tool");
if(!docbody.getElementById('_7Txt'))
{
var __7TxtDiv=docbody.createElement("div");
__7TxtDiv.setAttribute("id","_7Txt");
__7TxtDiv.style.display="none";
docbody.body.appendChild(__7TxtDiv);
}else{
__7TxtDiv=docbody.getElementById('_7Txt');
}
__7TxtDiv.innerHTML=linksbody;//为了使链接转换为URL,只好这样了....
var winname = window.open('', '_blank', 'top=10000');
winname.document.open('text', '');
winname.document.writeln(__7TxtDiv.innerHTML);
linksbody='';
_7txtObj.openSoft();//打开软件
//_7txtObj.chkStatus(1);
//var SelectLink = b.links[i].href;
_7txtObj.AddData('start',userURL);
for (var i=0; i<winname.document.links.length; i++) {
var oneLink = winname.document.links[i];
var mystr = oneLink.href+'$$$$$'+htmldecode(oneLink.innerText);
//linksbody+='<a href="'+oneLink.href+'">'+
//oneLink.innerHTML+'</a>';
_7txtObj.AddData(mystr,userURL);
//执行添加文章
}
winname.close();
_7txtObj.AddData('over',userURL);
//_7txtObj.chkStatus(2);这两个参数留着以后用
function htmldecode(str)
{
var re = /(<)/gi;
var rv = str.replace(re,"<");
re = /(>)/gi;
rv = rv.replace(re,">");
//re = /( )/gi;
//rv = rv.replace(re," ");
return(rv);
}
function getlinkbody()
{
var srcEvent = external.menuArguments.event;
