In the Web page, if the <script type= "text/javascript" ></script> tag appears two times, all Javascipt scripts will no longer take effect, only one <script type= " Text/javascript "></script> tags, however, multiple JavaScript effects are often required on the same Web page.
I. BASIC OBJECTIVES
Mount two JavaScript clocks in the Web page, one of which is the normal time to walk every 1 seconds, the other is the abnormal clock that goes once every 3 seconds, just to differentiate, to explain how to implement multiple JavaScript effects in the same Web page.
Second, the production process
First of all to achieve the effect of writing into a function, the function A (), B (), and then through the body's onload, so that it loads the page immediately to load the function.As for Clocka () and clockb (), it is rewritten according to the original JavaScript code. The original JavaScript code in <body> is as follows:
<script type= "Text/javascript" >function clock () {var time = new Date (). toLocaleString ();d Ocument.getelementbyid ("Clock"). InnerHTML = time;} SetInterval ("clock ()", ";</script>")"JavaScript" implements multiple JavaScript effects in the same Web page
