greasemonkey插入javascript [英] greasemonkey insert javascript

问题描述

我有一个书签，点击书签包含一个PHP脚本（评估为JavaScript文件）到页面的几个表值，并选择作为GET参数传递的值。 PHP脚本将页面数据写入MySQL数据库，并输出成功消息，该消息被视为JavaScript代码并由浏览器执行。是否有可能使用greasemonkey执行此操作，并在网页上单击现有按钮时调用此函数。

I have a bookmarklet, clicking the bookmarklet includes a PHP script (evaluated as a JavaScript file) to the page few table values and select values passed as GET parameters. The PHP script writes the page data to the MySQL database, and outputs a success message that is treated as JavaScript code and executed by the browser. Is there any possibility to do this using greasemonkey and call this function when a existing button is clicked on the web page.

我编写了本教程启发的上述书签。

I wrote the above bookmarklet inspired by this tutorial.

http://tutorialzine.com/2010/04/simple-bookmarking-app-php-javascript-mysql/

这是书签代码：

(function () {
var jsScript = document.createElement('script');

jsScript.setAttribute('type', 'text/javascript');

jsScript.setAttribute('src', '/bookmark.php?url=' + encodeURIComponent(location.href) + '&title=' + encodeURIComponent(document.title));

document.getElementsByTagName('head')[0].appendChild(jsScript);
})();

请帮帮我。

推荐答案

我们做了很多。
这是一个应该适合您的脚本，只需编辑 @include 语句以匹配将使用Greasemonkey脚本的页面。

We do this a lot. Here's a script that should work for you, just edit the @include statement to match the pages the Greasemonkey script will be used on.

此外， /bookmark.php 可能必须更改为完整地址，而不是相对地址。

Also, /bookmark.php will probably have to be changed to a full address, rather than a relative one.
