User · Answer

Below you have some VALID html5 example document. The type attribute in script tag is not mandatory in HTML5.

You use jquery by $ charater. Put libraries (like jquery) in <head> tag - but your script put allways at the bottom of document (<body> tag) - due this you will be sure that all libraries and html document will be loaded when your script execution starts. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.

<html lang="en">_x000D_
<head>_x000D_
    <meta charset="utf-8">_x000D_
    <title>Example</title>_x000D_

You can add script tags in your HTML document  ideally inside the  which points to your javascript files  Order of the script tags are important  Load the jQuery before your script files if you want to use jQuery from your script    lt script type  text javascript  src  http   ajax googleapis com ajax libs jquery 1 7 1 jquery min js  gt  lt  script gt   lt script type  text javascript  src  relative path to your javascript js  gt  lt  script gt    Then in your javascript file you can refer to jQuery either using   sign or jQuery  Example   jQuery each arr  function i    console log i

To include an external Javascript file you use the  lt script gt  tag   The src attribute points to the location of your Javascript file within your web project    lt script src  some js  type  text javascript  gt  lt  script gt    JQuery is simply a Javascript file  so if you download a copy of the file you can include it within your page using a script tag   You can also include Jquery from a content distribution network such as the one hosted by Google    lt script src    ajax googleapis com ajax libs jquery 1 8 3 jquery min js  gt  lt  script gt
