I am of course talking about the hash symbol (also known as pound or number) – #.

In websites the # symbol splits a URL into anchors. Everything before the # is the URL, everything after is an anchor tag. We use # to allow people to jump to specific areas on the page.

For example:

<a name="topanchor">Hi</a>

<a href="#topanchor">Click to jump to the top</a>

When you click the second link, your screen will jump to the first link (if this page is long enough for scrollbars).

But there’s one annoying place people use it. In Javascript calls on links. It’s much prettier to use # than the other method of Javascript.Void(0);

Except, it introduces a new problem. It’s great to have people clicking a link that activates a javascript function without actually reloading/changing the page, but if you use a # and the user is at the bottom of the page, they’ll be bounced to another section on it. Seriously. It’s a huge pain when you’re clicking a button (that’s actually a image/link) and then you’re bumped to the top of the page.

I didn’t write these, but they’ve been passed around a lot. They’re useful if you need some basic JavaScript functions.

Left Trim
Pass it a string to trim and any characters that should be trimmed from the left. chars can be left empty to trim spaces.

function ltrim(str, chars) {
	chars = chars || "\\s";
	return str.replace(new RegExp("^[" + chars + "]+", "g"), "");
}

Right Trim
Works exactly the same as the left trim, just on the right.

function rtrim(str, chars) {
	chars = chars || "\\s";
	return str.replace(new RegExp("[" + chars + "]+$", "g"), "");
}

Trim
Combines the left & right trim to have a full trim functions.

function trim(str, chars) {
	return ltrim(rtrim(str, chars), chars);
}
