I won’t talk about the basic concepts here. I typed out my first javasript program according to the code in the book, which is my own hello world. It is a great encouragement to myself. I will post the code below and let everyone learn together.
index.php
<code><span><span><?php</span>header(<span>'Content-type:text/html'</span>); <span>include</span><span>'test.html'</span>; <span>?></span></span></code>
test.html
<code><span><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"></span><span><<span>html</span>></span><span><<span>head</span>></span><span><<span>meta</span><span>http-equiv</span>=<span>"Content-Type"</span><span>content</span>=<span>"text/html; charset=GB18030"</span>></span><span><<span>script</span><span>type</span> =<span>"text/javascript"</span>></span><span><span><span>function</span><span>cubeme</span><span>(incomingNum)</span>{</span><span>if</span>(incomingNum ==<span>1</span>){ <span>return</span><span>"what are you doing ?"</span>; }<span>else</span>{ <span>return</span><span>Math</span>.pow(incomingNum,<span>3</span>); } } </span><span></<span>script</span>></span><span><<span>title</span>></span>JavaScript Test<span></<span>title</span>></span><span></<span>head</span>></span><span><<span>body</span>></span><span><<span>script</span><span>type</span> =<span>"text/javascript"</span>></span><span><span>var</span> theNum =<span>2</span>; <span>var</span> finalNum =cubeme(theNum); <span>if</span>(<span>isNaN</span>(finalNum)){ alert(<span>"You should know that 1 to any power is 1."</span>); } <span>else</span>{ alert(<span>"when cubed ,"</span> + theNum + <span>"is"</span> + finalNum); } </span><span></<span>script</span>></span><span></<span>body</span>></span><span></<span>html</span>></span></code>
The running results are as follows:
The above introduces the first JavaScript program for PHP development, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
