我正在编写一个 greasemonkey 脚本来操作 DOM、查询服务器并在单独的 jquery 对话框中显示结果。 我想为其添加以下两个功能:

1. 提供一个搜索框，其作用类似于在浏览器上进行简单搜索(即仅搜索 jquery 对话框 的内容并突出显示文本)。
2. 提供一个文本框，除非用户专门更改它，否则应永久存储其内容以供将来使用用户脚本。

我面临的问题是，我想将这两个都包含在对话框的 ui-dialog-buttonpane 区域中，在关闭按钮的左侧，但我不知道该怎么做。

我所知道的是，我可以使用 window.find()(此处使用 http://www.javascripter.net/faq/searchin.htm)启用浏览器查找功能。

有人可以帮我解决这个问题吗？以下是我现有的 greasemonkey 脚本的代码:

最佳答案

要在 ui-dialog-buttonpane 中包含“关闭”按钮左侧的控件，您可以使用 .ui-dialog-buttonset 上的 .prepend() 函数 像这样的类:

$('.ui-dialog .ui-dialog-buttonset').prepend('<input type="text"/><button class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"><span class="ui-button-text">Search</span></button>');

您很可能希望为正在使用的特定对话框添加一个选择器，以避免将此控件添加到页面上的任何对话框。根据您的示例，它将是这样的:

$('div[aria-describedby=SSOverlayDialog]').find('.ui-dialog-buttonset').prepend('<input type="text"/><button class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"><span class="ui-button-text">Search</span></button>');

希望这有助于解决主要问题。 祝你好运!
