javascript - Uncaught ReferenceError $ is not defined -


I am very new to javascript (just started a few hours ago and a script was trying to work ). I went to some tutorials on W3 and the 'Hello World' code works when I paste it directly into my HTML, but I have a problem with a script (I have problems with other scripts I'm not sure what I'm doing).

I have that I want to test in my HTML, I have copied it in HTML and it looks like this, then I have my code named as edit.js The folder is created and it was copied to Javascript (as shown in the exact same way) No errors work on this page, but when I click, nothing happens. I tried to paste a W3 'Hello World' code and it works but this script is not.

I tried to inspect the code in Chrome and here I see the error above (under the Resources tab). I can open the JS file using Chrome which I think is that the JS file is accessible and correctly indicates, but I'm not sure how to work it. I will use HTML as my template engine I am using GenZ2 as my form and I have it in my headline:

    

And I have my main template (which sings on all pages):

    

edit.js:

(I want to use it directly by putting it on the script tag on the page ( $ ('# Stored value'). Hide (); $ ('# altervalue'). Show ();}); $ ('# Savevalue') Click (function (e) {var showNew = $ ('# $ ('# Storedvalue') Show (); $ ('#valuedvalue span'). Text (showNew);});

HTML:

(this is embedded in a large page)

  & Lt; head & gt; Script language = "javascript" src = "http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" Ser = "text / javascript">
