< html>
< form>
在此处粘贴URL：< input name = url value =''http：//www.yahoo.com''>
< input type = button onclick = QUOT;尝试（）" value = Go>
< input type = reset>
< / form>
< p id = here>< / p>
< script>
函数try（）{
if（document.forms [0] .url.value ==' '''）{return};
//用用户的url打开一个新窗口。
window2 = window.open（document.forms [0] .url.value，"，"" height = 0，width = 0"）;
//获取新网页的内容。下一行是获得
访问拒绝错误的行。
t = window2.document.body.innerHTML;
//显示此页面中的内容。
here.innerHTML = t;
//关闭新页面。 />
window2.close（）;
};
< / script>
< / html>
Hi all. I''m a bit of a novice in this arena so please forgive if this
question reflects that. I am trying to grab the html from a website and
display it within another webpage (once I get this to work I am going to
manipulate the html in other ways - this isn''t the end purpose of this
effort). To do this I am trying to open another window containing the
source html from a URL and then capture the html from that window. I
can open the window fine but get an "access denied" error when trying to
assign the html to a variable. The basic code follows. Basically any
way that I can assign the html that results from an entered URL to a
javascript variable or object that I can then manipulate should work for
me. Suggestions?
Thanks in advance
Larry
<html>
<form>
Paste URL here: <input name=url value=''http://www.yahoo.com''>
<input type=button onclick="try()" value=Go>
<input type=reset>
</form>
<p id=here></p>
<script>
function try() {
if (document.forms[0].url.value=='''') {return};
// open a new window with the url from the user.
window2=window.open(document.forms[0].url.value,"","height=0,width=0");
// get the content of the new page. NEXT IS THE LINE THAT GETS THE
ACCESS DENIED ERROR.
t=window2.document.body.innerHTML;
// display the content in this page.
here.innerHTML=t;
// close the new page.
window2.close();
};
</script>
</html>
