HTML Help detection

[Thomas Steinbach]

Hello,

is it possible to detect in a webpage if it is diplayed
in a HTML Help File (chm)?

And what is the engine and identification of "the"
HTML Help "Browser"? IE7 ?

Hi, Thomas,

Yes, you can use a script like the one below to determine whether the
current page is compiled into a .chm file or not.

<script type="text/javascript">
<!--

// Search for a double colon in the URL of the current file.
// If none is found then the file isn't compiled into a CHM.
var a = location.href.search("::");

if (a <= 0) {
// Current file is NOT compiled into a CHM.
alert("Not in a CHM");
}

else {
// Current file IS compiled into a CHM.
alert("Compiled into a CHM");
}

//-->
</script>

Yes, HTML Help uses Internet Explorer, but any version of IE from 3.02
onwards will do (the more modern, the better). See:
