1 JS方式調用PHP檔案並取得php中的值
舉一個簡單的例子來說明:如在頁面a.html中用下面這句調用:<script type="text/javascript" src="b.php?action=test"></script><script type="text/javascript" >alert(jstext);</script>在b.php中有這樣一段PHP代碼:<? $action=$_GET[‘action‘]; //echo "var jstext=‘$action‘"; //輸出一句JS語句,產生一個JS變數,並賦顛值為PHP變數 $action的值 //echo "var jstext=‘aa‘"; echo "var jstext="."‘$action‘"; ?>當執行a.html檔案時,就會調用b.php檔案,並將b.php檔案的輸出作為JS語句來執行,所以此處會彈出一個提示框,內容為JS變數jstext的值,也就是在PHP檔案中賦給jstext的值.小結:在HTML裡用JS 調用檔案的方式調PHP檔案,則PHP檔案的輸出將會被調用頁作為JS的代碼來用.2 php調用js中的值在z.php頁面中有這樣一段代碼：<script type="text/javascript" > var url="aaaa*"; </script> <? $key="<script type=text/javascript>document.write(url)</script>"; echo $key; ?>3 php調用js中的方法(函數)<script type="text/javascript"> function test() { var t1=3; t1 = t1+2; alert(t1); //return t1; } </script><?php echo "<script type=‘text/javascript‘>test();</script>"; ?>4 JS調用PHP變數（1）<?php$userId=100;?> <script>var userId;userId=document.getElementByIdx_x_x_x("userId").value;alert (userId);</script><input type="text" name="userId" id="userId" value="<?php echo $userId; ?>">（2）<?php$url = ‘變化的網址‘; //定義變數?><script type="text/javascript">//js調用php變數var ds ="<?php echo $url?>" ; //賦值 alert(ds); //輸出效果 </script>5 -------------------------------<script language="JavaScript"> <!--var Y=<?php echo date(‘Y‘)?>,M=<?php echo date(‘n‘)?>,D=<?php echo date(‘j‘)?>;--></script>6 自己寫的js和php互相調用1.php內容：<?php//echo "<script LANGUAGE=‘javascript‘>alert(‘$php變數‘);</script>"; //最簡單的php調用js//echo "<a href=#><img width=50 src=‘$fruit_pic_array[$i]‘ onMouseOver=’javascript:a();‘></a>";//echo "<a href=‘3.php‘>aaaa</a>"; //php中超連結//echo "<script type=‘text/javascript‘ language=‘javascript‘>phpmake(‘PHP建站學習筆記網‘);</script>"; //有時候需要在PHP執行過程中，需要調用JavaScript自訂函數(驗證時出錯)echo "function ok(msg){alert(msg);}";?><HTML><HEAD><TITLE> php調用js檔案的好辦法</TITLE></HEAD><BODY><!--js調用php中定義的js--><scrīpt language=‘‘javascrīpt‘‘ type=‘‘text/javascrīpt‘‘ src=‘‘1.php‘‘></scrīpt><scrīpt>ok("aaaaaa!");</scrīpt></script></BODY></HTML>2.php內容：<!--js調用php--><?php$userId=100;?><script>var userId;userId=document.getElementByIdx_x("userId").value;alert (userId);</script><input type="text" name="userId" id="userId" value="<?php echo $userId; ?>"><!--js調用php--><?phpif($_GET["action"]=="ok"){echo "I‘m OK!";}else{echo "I‘m not OK!";}?><SCRIPT Language = "JavaScript">function func(){if(confirm("Are you OK with this?")){this.location = "ok.php?action=ok";}else{this.location = "ok.php?action=cancel";}}</SCRIPT><html><head></head><body><a href="#" href="#" onClick="javascript:func();">Please Click</a></body></html><!--js調用php--><html><head><script>function isMail(PostString){re=/\w*/if(re.test(PostString)){return true;}else{return false;}}function test(){if (isMail(<?php echo $email?>)){document.write("<?php echo "N";?>");}else{document.write(‘<?php echo ‘Y‘;?>‘);}}</script></head><body><?php$email="aa";?><input type=button value=click onclick= ‘test() ‘></body></html><!--php中含有js代碼--><?phpecho "<script language=javascript>function test(){alert( ‘hello ‘);}</script> ";?><input type=button value=click onclick= ‘test() ‘>js php 互調
