我创建了一个 chrome 扩展，其中有一个弹出窗口，其中包含以下 HTML 标记:
I have created a chrome extension that has a popup with the following HTML markup in it:
<html> <head> <style> body { font-family: 'Open Sans',arial,sans-serif; background-color: #E5E5E5; font-size: 13px; text-shadow: 0px 1px rgba(255, 255, 255, 0.5); } </style> </head> <script type="text/javascript">function sendRequest(s,r){ chrome.tabs.getSelected(null, function(tab) { chrome.tabs.sendRequest(tab.id, {search:s , replace:r}, function(response) { console.log(response.farewell); }); }); }; </script> <body> <label for="search">Search for</label><input name="search" id="search"></input> <label for="replace">Replace with</label><input name="replace" id="replace"></input> <button onclick="var s=document.getElementById('search').value;var r=document.getElementById('replace').value;sendRequest(s,r);">Go</button> </body> </html>当我打开弹出窗口时，选择第一个输入字段，然后按 Tab 键，输入字段失去焦点，但第二个没有获得焦点.
When I open the popup, select the first input field and then press the tab key, the input field loses focus but the second one does not gain focus.
如果我再次选择第一个并再次按 Tab，则第二个字段获得焦点.再次按下使按钮获得焦点，第三次按下使第一个字段再次获得焦点.
If I then select the first one again and press tab once more, the second field gains focus. Pressing again makes the button gain focus and pressing a third time makes the first field gain focus once more.
有谁知道为什么第一次按 Tab 键不起作用?
Does anyone know why the first tab key press would not work?
