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() '>
