未检测到 Vuejs
Posted
技术标签:
【中文标题】未检测到 Vuejs【英文标题】：Vuejs is not detected 【发布时间】：2018-12-11 03:04:06 【问题描述】：大家好，请帮忙！在我的页面上未检测到 Vue js。我不知道为什么。我过去构建了很多 vueapps，以前从未遇到过问题。我想知道引导 js 是否与 vuejs 冲突？我加载页面，当我尝试进入 chrome 开发工具时，它说未检测到 vuejs。脑洞大开！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;

【问题讨论】：
你在使用 vue 开发工具吗？ 是的，我正在使用 vue 开发工具 看这段代码好像根本不需要Vuejs。 是的，我做 v-on:click="submit();"我想用vuejs可以吗？ 希望奥基夫先生永远不会注册.. 【参考方案1】：为了使 vue 开发工具正常工作，页面上应该至少有一个 Vue 实例。
因为您的数据存在转义问题。你的 Vue 实例永远不会被创建
转换自
sesusername: '<?php if (isset($_SESSION['username'])) echo $_SESSION['username'];?>',
到
sesusername: '<?php if (isset($_SESSION["username"])) echo $_SESSION["username"];?>',
