我们在使用
PHP与Javascript交互的方法:通过Cookie交互。一共是三个文件,分别为:
index.htm,action.php,main.htm
原理为前台页面main.htm和后台action.php通过页面框架,index.htm组织起来,将action.php的页面宽度设为0,这样并不影响显示。action.php将信息放入cookie中,main.htm通过读取
cookie来实现交互。在main.htm中也可以通过重新读取action.php来实现控制后台CGI程序。
PHP与Javascript交互的实现代码:
<ol class="dp-xml"> <li class="alt"><span><span class="tag"><span> </span><span class="tag-name">html</span><span class="tag">></span><span> </span></span></span></li> <li><span class="tag"><span> </span><span class="tag-name">head</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> </span><span class="tag-name">title</span><span class="tag">></span><span>Test</span><span class="tag"><span> /title</span><span class="tag">></span><span> </span></span></span></li> <li><span class="tag"><span> </span><span class="tag-name">meta</span><span> </span><span class="attribute">http-equiv</span><span>=</span><span class="attribute-value">"Content-Type"</span><span> <br></span><span class="attribute">content</span><span>=</span><span class="attribute-value">"text/html; charset=gb2312"</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> /head</span><span class="tag">></span><span> </span></span></li> <li><span class="tag"><span> </span><span class="tag-name">frameset</span><span> </span><span class="attribute">framespacing</span><span>=</span><span class="attribute-value">"0"</span><span> <br></span><span class="attribute">border</span><span>=</span><span class="attribute-value">"false"</span><span> </span><span class="attribute">frameborder</span><span>=</span><span class="attribute-value">"0"</span><span> </span><span class="attribute">cols</span><span>=</span><span class="attribute-value">"0,*"</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> </span><span class="tag-name">frame</span><span> </span><span class="attribute">name</span><span>=</span><span class="attribute-value">"leftFrame"</span><span> </span><span class="attribute">scrolling</span><span>=</span><span class="attribute-value">"no"<br></span><span> noresize </span><span class="attribute">src</span><span>=</span><span class="attribute-value">"action.php"</span><span class="tag">></span><span> </span></span></li> <li><span class="tag"><span> </span><span class="tag-name">frame</span><span> </span><span class="attribute">name</span><span>=</span><span class="attribute-value">"rightFrame"</span><span> </span><span class="attribute">scrolling</span><span>=</span><span class="attribute-value">"auto"</span><span> <br></span><span class="attribute">src</span><span>=</span><span class="attribute-value">"main.htm"</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> /frameset</span><span class="tag">></span><span class="tag"><span> </span><span class="tag-name">noframes</span><span class="tag">></span><span> </span></span></span></li> <li><span class="tag"><span> </span><span class="tag-name">body</span><span> </span><span class="attribute">bgcolor</span><span>=</span><span class="attribute-value">"#FFFFFF"</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> </span><span class="tag-name">p</span><span class="tag">></span><span>本页使用页面框架,但是您的浏览器不支持。</span><span class="tag"><span> /p</span><span class="tag">></span><span> </span></span></span></li> <li><span class="tag"><span> /body</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> /noframes</span><span class="tag">></span><span> </span></span></li> <li><span class="tag"><span> /html</span><span class="tag">></span><span> </span></span></li> <li class="alt"><span class="tag"><span> ? </span></span></li> <li><span>srand((double)microtime()*1000000); </span></li> <li class="alt"> <span>$</span><span class="attribute">result</span><span>=</span><span class="attribute-value">rand</span><span>(0,100); </span> </li> <li><span>setcookie("action",$result,time() 900,"/"); </span></li> <li class="alt"> <span class="tag">?></span><span> </span> </li> </ol>
以上就是PHP与Javascript交互的具体实现方法。
