Several useful tips for JQuery

JQuery code

/* Open the link in a new window: JQuery filter attr
* Disable the mouse to pop up the right-click menu: DOM contextmenu
* Return to the top of the page: DOM scrollTo
* Dynamically replace the CSS style sheet: JQuery filter Element Attribute
* Adjust the page Font size: Css html.css parseFloat
*/
//Confirm that DOM loading is complete
$(document).ready(function () {

/* Links with href attributes starting with http will open the link in a new window* /
// ^ Filter, attribute: start with a specific string
$("a[href ^='http']").attr("target", "_blank");

/* Disable right mouse button* /
//DOM contextmenu is the right-click menu of the mouse
$(document).bind("contextmenu", function (e) {
alert(("No right-clicking!"));
//Do not execute downward, In other words, the right-click menu does not appear
        return false;
  });

  /* Return to the top of the page*/
  //The click event of the element with id="top" is triggered
  $('#top').click( function () {
                // Return to the top of the page
            $(document).scrollTo(0, 500);
  });
