大家好，请帮忙！我的页面上未检测到Vue js。我不知道为什么。过去，我已经开发了很多vueapp，而且以前从未遇到过问题。我想知道引导js是否与vuejs冲突？我加载了页面，当我尝试使用chrome开发工具时，它说未检测到vuejs。烦死了！有什么想法吗？
<?php ob_start(); session_start();
if (isset($_SESSION['activated'])) {
$activated = $_SESSION['activated'];
}
if (isset($activated) && $activated == 0) {
echo '<script type="text/javascript">';
echo 'alert("Please activate your account before signing in. ");';
echo 'window.location.href = "resendoptions.php?userName=' . $_SESSION[username] . '";';
echo '</script>';
}
if (isset($_SESSION['success']) and $_SESSION['success'] == 1) {
$success = 1;
}
else {
$success = 0;
}
?>

要使vue devtools正常工作，页面上应该至少有一个Vue实例。
由于您的数据存在转义问题。您的Vue实例永远不会创建
转换自
FROM `93868086.ga_sessions_*`
到
sesusername: '<?php if (isset($_SESSION['username'])) {echo $_SESSION['username'];}?>',
