1.PHP 

  a.PHP -> HTML & JavaScript 

  额 超简单,我也要写= =~ 

  html代码中 

<input type="" readonly="readonly" style='background-color:#DCDCDC' value=<?php echo $perinfo[ID];?> /> 
   JavaScript代码中 

复制代码代码如下:


<script type="text/javascript"> 
var ability=<?php echo JSON($array);?>; 
</script> 


  b.PHP <-> MySQL 

  php代码中 

复制代码代码如下:


<?php 
$dbcnx = @mysql_connect ( "localhost", "root", "1234" ); 
if (! $dbcnx) { 
echo ("Unable to connect to the " . "database server at this time."); 
exit (); 


if (! @mysql_select_db ( "pms" )) { 
echo ("Unable to locate the joke " . "database at this time."); 
exit (); 

mysql_query ( "SET NAMES 'GB2312'" ); 


$q=mysql_query("select * from ability where ALV = 1"); 
while($row=mysql_fetch_array($q)){ 
$array1[] = $row[AName]; 

?> 


2.HTML 

  a. HTML -> PHP (POST方式) 

  html代码中 

复制代码代码如下:


<form id="form" name="form" method="POST" action="do.php"> 
<input type="hidden" id="count" name="count" value="1"/> 
<input type="submit" name="Submit" value="Search"/> 
</form> 


  do.php 文件代码中 

复制代码代码如下:


<?php 
echo $_POST['count']; 
?> 


  b. HTML -> JavaScript 


  JavaScript代码中 (可获得,可更改) 

复制代码代码如下:


<script type="text/javascript"> 
var te = document.getElementById("count"); 
te.value = 1; 
</script> 


3.JavaScript 

  a. JavaScript -> HTML (通用法, 未验证) 

  JavaScript代码中 

复制代码代码如下:


<script type="text/javascript"> 
function f(){ 
var id = "2"; 
var a = document.getElementById("a"); 
a.href.replace("(n)", id); 

</script> 



html代码 

复制代码代码如下:


<a id="a" href="ExportArticle.action?articles=(n)"/> 


  b. JavaScript -> PHP 

  通过html的转接 

  1.JavaScript代码先给html 

复制代码代码如下:


<script type="text/javascript"> 
var i = 1; 
var te = document.getElementById("count"); 
te.value = i; 
</script> 


  2.html代码给php 

复制代码代码如下:


<form id="form" name="form" method="POST" action="do.php"> 
<input type="hidden" id="count" name="count" value="1"/> 
<input type="submit" name="Submit" value="Search"/> 
</form> 


  3.do.php接收到 

复制代码代码如下:


<?php 
echo $_POST['count']; 
?>
