javascript - Opencart 3.0 - 如何使用事件系统从目录 Controller 添加内联 JavaScript 代码？

Question

如何从 Controller 添加内联js代码？

管理模块 Controller

$this->model_setting_event
     ->addEvent("one_two_three","catalog/view/common/header/before","extension/module/oone_two_three/inject_abc_javascript");

以及目录模块 Controller

public function inject_abc_javascript(&$route, &$data){
    $code = $this->config->get("module_one_two_three_code");
    $data["scripts"] = "<script>OneTwo.push(function() {
  OneTwo.init({
      appId: $code,
  });});</script>";
}

有没有办法在 OpenCart header 中添加内联 JavaScript？

Answer 1

是的，你可以做到。

首先，addEvent 参数中有错误/拼写错误，请将 oone_two_third 更改为 one_two_ Three。

然后你的函数需要第三个参数:

public function inject_abc_javascript($route, &$data = false, &$output = false){
    // Before closing tag
    $hook = '</head>';
    $js = '<script>alert("Hello from one_two_three module!");</script></head>';
    $output = str_replace($hook, $js, $output);
}
