Question

Basically, if the URL/window.location contains absolutely any variable whatsoever (past domain.com/, of course), I’d like javascript to execute something.

Currently, I have the following jQuery code which only executes when window.location contains the exact wording “#hash”, but as stated before I’d like to expand the functionality for all variables.

Edit: Sorry, to clarify, by variable I mean any one of the following examples:

• domain.com/#hash
• domain.com/#hash2
• domain.com/sub/folder
• domain.com/textwithoutahash

Also, if someone knows how to do this in basic Javascript and without the need for the jQuery library, that would be an added bonus!

$(function() {
    if ( window.location.href.indexOf('#hash') > -1 ) {
        myfunctionhere;
    }
});

See update at end re your clarification

Put the script at the end of the page, just before the closing </body>, and:

If by “variable” you mean a document fragment identifier (“hash”), then:

<script>
if (location.hash) {
    callYourFunction();
}
</script>

If by “variable” you mean a query string, then

<script>
if (location.search) {
    callYourFunction();
}
</script>

If by “variable” you mean a resource name, e.g., not http://domain.com but http://domain.com/page, then:

<script>
if (location.pathname && location.pathname !== "/") {
    callYourFunction();
}
</script>

Re your clarification:

Edit: Sorry, to clarify, by variable I mean any one of the following examples:

Those examples come down to having either hash or pathname or both, so:

<script>
if ((location.pathname && location.pathname !== "/") || location.hash) {
    callYourFunction();
}
</script>

…and of course, if you also wanted to handle http://domain.com?foo=bar, then add in search as well:

<script>
if ((location.pathname && location.pathname !== "/") ||
    location.search ||
    location.hash) {

    callYourFunction();
}
</script>
