[PHP] PHP & HTML & JavaScript & MySQL 代码如何互相传值

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

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

　　b.PHP  <-> MySQL

　　php代码中

<?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

<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

<?php
echo $_POST['count'];
?>

　　b. HTML -> JavaScript

　　JavaScript代码中 (可获得，可更改）

<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 

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

　　html代码

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

　　b. JavaScript -> PHP

　　通过html的转接

　　1.JavaScript代码先给html

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

　　2.html代码给php

<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

<?php
echo $_POST['count'];
?>
