Escapes any character that has a special meaning in a CSS selector.
|Selector||A string containing a selector expression to escape.|
This method is useful for situations where a class name or an ID contains characters that have a special meaning in CSS, such as the dot or the semicolon.
The method is essentially a shim for the CSS Working Group's CSS.escape() method. The main difference is that
$.escapeSelector() can be reliably used in all of jQuery's supported browsers.
Escape an ID containing a hash.
$.escapeSelector("#target"); // "\#target"
Select all the elements having a class name of
.box inside a
$("div").find("." + $.escapeSelector(".box"));
