好的,所以我不是程序员,所以请不要打扰我太多...我有一个情况,我有一些javascript(对于jqgrid),我想要一些值来填充一个PHP变量。我做的就是使用PHP并将所有的javascript代码放在'here document'中。所有看起来都很好但我想我会联系你们所有人,看看是否有办法简化我的编程。代码如下以供参考。
global $database;
$switchesStr = "";
$sql = "SELECT id,name FROM switch ORDER BY name asc";
$result = $database->query($sql);
while($row = mysql_fetch_array($result,MYSQL_NUM)) {
$switchesStr .= $row[0].":".$row[1].";";
}
$switchesStr = substr_replace($switchesStr,"",-1);
$vlansStr = "";
$vlansStr = "0:System Default;";
$sql = "SELECT id,vlan_description FROM vlan ORDER BY default_name asc";
$result = $database->query($sql);
while($row = mysql_fetch_array($result,MYSQL_NUM)) {
$vlansStr .= $row[0].":".$row[1].";";
}
$vlansStr = substr_replace($vlansStr,"",-1);
echo <<<DOC

我相信这样做的最好方法就是在你的javascript里面回应你需要的东西。例如json_encode
:
<?php $name = 'Ben'; ?>
<script type="text/javascript">
var name = <?php echo json_encode($name); ?>;
alert(name);
</script>
或者,如果您知道值的类型并且它不复杂(如字符串):
<script type="text/javascript">
var name = "<?php echo $name; ?>";
alert(name);
</script>

您可以在运行时使用PHP写入信息......
<script type="text/javascript" language="<strong class="highlight">javascript</strong>">
<!--
<?php
echo("firstVar = $var1;");
echo("2ndVar = $var2;");
?>
// -->
</script>

好吧,如果你这样舒服,继续。风格永远是个人的......
BenMills和Urda的方法也可以。并且,当javascript中的变量是字符串时,不要忘记引用它。
