Enqueue jQuery for front of site in a plugin

So I know how to load jQuery on the front end of a site, but my problem is what if its already been loaded by the theme or another plugin?

I am asking because I have seen in the past with sites I have inherited that jQuery has been loaded more than once and it caused conflicts. I had to go into the plugin and remove it but when I update the plugins I have to go back in an remove it again.

So my question is how can I find out if there is jQuery already loaded?

Hi JP,

"Say you were going to do an include on a whole bunch of pages, and inside of that include you wanted to do some jQuery specific stuff. That page may or may not already have jQuery loaded. If it already does, you don't want to load it again, but if not, you do. This works for that."

Hope it will help.

Hi Kevin,

Many thanks for this. I never thought to look for a JS solution for this. I'm going to add this to my plugin.

I was actually trying to find a solution within my WordPress plugin PHP, I would really like to see if there is a solution for use in my plugin too so will still leave the question open.
