将一个php变量回显到innerhtml中

Question

我的代码有问题,我想将$含义变量放入我的di的innerhtml中,这是我的代码:searchinput.php:

<form action = "search.php" method = "post">
    <input name="word" id="word" type="text" maxlength="255" />
    <label for="word">word:</label></br></br>
    <input type="submit" value="search" />

</form>
<div id = "meaning"> </div>

search.php中:

<?php
    $db = mysql_connect("localhost", "root", "");
    mysql_select_db("project",$db);
    $word = isset($_POST["word"]) ? $_POST["word"] : "";
    $result = mysql_query("select meaning from vocabulary where word = '$word'");
    $fetchmeaning = mysql_fetch_array($result); 
    $meaning = $fetchmeaning['meaning'];
?>

现在我想要这个:

document.getElementById('meaning').innerhtml = $meaning; !!!!

我怎么能阻止这个？

Answer 1

是.在定义之后启动脚本标记$meaning并将下面的代码放入其中.喜欢.

document.getElementById('meaning').innerHTML = "<?PHP echo $meaning; ?>" ;

你也不能想到直接回应$meaning里面的价值div甚至没有使用javascript？喜欢

<div id = "meaning"><?PHP echo $meaning; ?></div>

您也可以使用简短表格<?=$meaning?>.
