我有四个选项卡式页面(Amazon,Google和eBay),而最后一个是我的主页。主页上有一个用户条目,下面带有一个搜索按钮。我想同时在所有三个网页(选项卡式页面)上搜索用户输入。无论如何,是否要将“输入/输入”传递给其他三个页面的url?例如“(-)+(用户输入)”。例如,如果有人想购买一台新笔记本电脑,则第一页将接受输入并将其添加到每个页面的URL中。 ....本质上,其他两个选项卡式页面的webview =(“ https://www.google.com/” +笔记本电脑)依此类推。希望我能很好地解释我的问题!预先谢谢大家!!!!

当然还有其他方法可以实现,但是想到的一种方法是包含搜索文本的静态变量。然后,当用户单击每个选项卡式页面时,即在该页面加载时,只需执行特定的搜索URL,包括静态变量中的搜索文本即可。
