   JavaScript程式碼中


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


  b.PHP <-> MySQL

  php程式碼中


<?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程式碼中


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

</form>

  do.php 文件程式碼中

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

  b. HTML -> JavaScript

  JavaScript程式碼中

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

3.JavaScript

  a. JavaScript -> HTML (通用法, 未驗證)

  JavaScript程式碼中

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

html

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

  b. JavaScript -> PHP

  通過html的轉接

  (1).JavaScript程式碼先給html

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

  (2).html程式碼給php

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

  (3).do.php接收到

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