Question

<script type="text/javascript">
function Invest()
{
    alert("Mechanical /n Electrical /n Computer /n Civil");
}
function create()
{
    alert("Graphic /n Interior /n Architecture");
}
function motivate()
{
    alert("Business Administration /n Accounting and Finance");
}
</script>

以上代码是我的javascript代码

<form action="main.html" method="post">
   <?php
    $v2 = $_GET['dropdown'];
 if ($v2=="investigative" )
    {
        echo "<h3>It's recommended that you follow</h3><h2>Engineering School</h2>";
    }
else if ($v2=="creative" )
    echo "<h3>It's recommended that you follow</h3><h2>Arts School</h2>";
else if ($v2=="motivated" )
    echo "<h3>It's recommended that you follow</h3><h2>Business School</h2>";              
?>

我想要做的是将我的回声更改为div onclick，这样它将从javascript中调用我的函数并显示其中的信息。

像这样的东西

 echo ""<div onclick=Invest();"<h3>It's recommended that you follow</h3><h2>Engineering School</h2>";

当我这样做以为我收到错误

解析错误：语法错误，意外'onclick'（T_STRING），期待'，'或';'在第35行的C：\ xampp \ htdocs \ MyProject \ eval.php

我做错了什么以及如何做到这一点？我是php的新手：/

Answer 1

不是这样的echo ""<div onclick=Invest();...

你需要像这样把div标签放在双引号内，用于onclick属性打开单引号，因为双引号已经打开

echo "<div onclick='Invest()'><h3>It's recommended that you follow</h3><h2>Engineering School</h2></div>";

如何在php中创建一个onclick div
