调用插件的函数的JavaScript onLoad

一位朋友为我创建了一个插件，允许用户将帖子标记为已读或未读。此插件的代码如下：

当用户打开帖子时，我想将其标记为已读帖子。那我该怎么做呢？

如果我不能理解，请让我知道，我会尽量解释得更好。

非常感谢。

jQuery(function($) { var button = $(".post-read"), postId = button.data("id"); // Updates button attributes to match its data-action attribute function updateButton() { if(button.data("action") == "unread") { button.attr("src", "http://corentinbuet.fr/wordpress/wp-content/plugins/Read-Unread/LU.png"); button.attr("title", "Marquer comme Non lu"); } else { button.attr("src", "http://corentinbuet.fr/wordpress/wp-content/plugins/Read-Unread/NON_LU.png"); button.attr("title", "Marquer comme Lu"); } } // Mark post as read $.post("/wp-admin/admin-ajax.php", { idPost: postId, action: "read" }, function(response) { // Handle errors etc. button.data(\'action\', \'unread\'); updateButton(); }); $(".post-read").click(function() { // Fix: Declare variable var action = button.data("action"); var data = { "action": action, "idPost": postId }; $.post("/wp-admin/admin-ajax.php", data, function(response) { // Check for errors etc // Update button button.data("action", (action == "read") ?

在WordPress导航菜单之前和之后插入一个javascript横幅代码

我正在尝试开发一个插件，在wordpress导航菜单前后插入javascript横幅代码，但我找不到任何解决此问题的方法。有人知道吗？我也不能附加到Div ID，因为每个wordpress主题都使用不同的Div ID和类作为导航菜单。谢谢编辑：横幅代码是adsense javascript代码。Wordpress有wp\\u nav\\u菜单功能，我想在wp\\u nav\\u菜单之前和之后注入javascript。
