Smart JavaScript Auto Loader
Free Plugin for WordPress and ClassicPress
This free Plugin for WordPress and ClassicPress allows you to load additional JavaScript files without the need to change theme files
Adding additional JavaScript to your WordPress or ClassicPress website is not that easy if you are unfamiliar with PHP coding, because you have to change the theme.
This handy little plugin allows you to load additional JavaScript files without the need to change the theme code. To load additional scripts just put them into a directory named jsautoload
.

There are three different locations where you can place the additional files – Theme independent, Theme dependent and Child Theme dependent. If you want to load one ore more JavaScript files at the end of your HTML file just place them into a subdirectory named footer
.
