我正在尝试使用下面的代码构建一个注册表单，我仍处于开始阶段。我很难执行 PHP echo 语句中的任何 JavaScript 代码。

我尝试使用斜杠\'和转义 javascript 函数中的单引号和双引号\"，这适用于顶级 javascript 函数，但是一旦我添加了其他两个函数并应用相同的逻辑，所有 javascript 函数都停止工作。

有人可以建议什么是防止问题并轻松执行 php echo 语句中的 javascript 代码的最简单方法吗？

<?php

echo '

            if(re.test(email)) {

仅<?php ?>在需要时使用标签。不在标签内的任何内容都会被回显并像 HTML 一样对待。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Strict//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>      
    <script type="text/javascript">
        function validateEmail(email) { 

            var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;

            if(re.test(email)) {
                document.getElementById(\'result\').innerHTML = \'<img src=\"http://www.customotion.com/green_check_small.png\" style=\"width:15px;\"/> Valid\';
            } else {
