Make a url connection?

[nicholas4@gmail.com]

I'm trying to make a web page where a form lets you enter a url address
in a field and upon clicking the submit button, the text of the source
code of the page is displayed below the form. I know it'll have to
make a url connection in javascript but I don't how to do this. Please
help.

The usual context here is scripting HTML pages loaded via HTTP and there
while some browsers allow you to make a HTTP connection those
connections are restricted to the server the HTML page has been loaded from.
As for fetching the source of a text file from the server see the FAQ

You won't be able to use the XML HTTP Request object <url:
http://jibbering.com/2002/4/httprequest.html /> to do what you want
because it has no ability to retrieve content from a site that is not
the one it was loaded from.

The closest you can come is something like:

<form name="myForm">
<input type="text" name="theUrl"
value="http://www.yahoo.com">
<input type="button" name="myButton"
value="Retrieve source"
onclick="myFunc tion(this.form. elements['theUrl']);">
</form>
<iframe name="myIframe" ></iframe>
<script type="text/javascript">
function myFunction(url) {
var s = url.value;

if (window.frames && window.frames['myIframe']) {
window.frames['myIframe'].location.href = 'view-source:' + s;
}
}
</script>

But it opens the source in IE's default source viewer (not the iframe)
and doesn't work in Opera 7.54 at all.

Re: Make a url connection?

You could try to load the page into an iFrame then use the innerHTML
property to view the source. The end result should look something like
<< document.frames["iframenamehere "].document.inner HTML >>. Might not
work due to security restrictions, though
