我正在使用带有此扩展程序的谷歌浏览器 - Open Link in Same Tab .
它非常简单，基本上按照它说的做，强制所有链接在同一个窗口/选项卡中打开。我需要此功能来实现触摸屏信息亭左/右滑动导航。
当涉及到链接时，该插件工作得很好。但是，当在“提交”网络搜索表单中执行搜索时，它不起作用。大概是因为扩展强制所有带有 _blank 的内容在 _top 中打开，但它忽略了 forms。
我如何修改扩展以使其也考虑表单，并强制它们也在同一个选项卡中打开？
我已经下载了扩展并查看了代码，主要的js似乎在sametab.js文件中。我在下面包含了这个，我相信我可以以某种方式修改它以满足我的需要。
感谢任何帮助。

最佳答案
只需在 (function() {
var submitButtons = document.getElementsByTagName("button");
for (var i = 0; i < submitButtons .length; i++) {
submitButtons[i].setAttribute("target", "_top");
}
