Question

出于某种原因，我无法将注意力集中在我的popup.html中的texbox上。这是我到目前为止所尝试的内容：

popup.html：

<input type="text" id="textbox" name="aName" value="" placeholder="blah" />

popup.js：

//Attempt 1
$(function() {      
    $('#textbox').focus();
});

//Attempt 2
setTimeout(function() { $('#textbox').focus(); }, 1000);

我也试过没有javascript，只使用自动对焦属性：

<input type="text" id="textbox" name="aName" value="" placeholder="blah" autofocus />

But none of this worked...有什么想法吗？

注意：

正在调用popup.js，如果我把console.log（）我得到输出
弹出窗口由我们旁边的omnibar（default_icon）

此代码与我合作，尝试一下，这是一种解决方法

<!DOCTYPE >

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Sample Extens</title>
</head>
<body style="padding: 0px; margin: 0px;" >
    <script type="text/javascript" language="javascript">
        if (location.search !== "?foo") {
            location.search = "?foo";
            throw new Error;  // load everything on the next page;
            // stop execution on this page
        }
    </script>

    <div id="Def">
        <input type="text" id="textbox" name="aName" value="" placeholder="blah" />
        <script type="text/javascript" language="javascript">
            document.getElementById("textbox").focus();
        </script>
    </div>
</body>

Answer 2

我有同样的问题。我相信我能够通过在tabindex=1

等输入上设置明确的tabindex来使其工作

请尝试一下，让我知道它是否有效。

<强>更新

我有一个非常简单的例子适合我。我在Linux上使用Chrome 19。

manifest.js

{
"name": "Auto 'focus'",
    "version": "1.0",
    "manifest_version": 2,
    "description": "An extension to test setting focus",
    "browser_action": {
        "default_icon": "icon.png",
        "default_popup": "popup.html"
    }
}

popup.html

<!doctype html>
<html>
  <head>
  </head>
  <body>
    <a href="#">Link</a>
    <input type="text" id="foo" tabindex="1" />
  </body>
</html>

没有tabindex="1"，焦点最初是在链接上。使用tabindex="1"时，焦点在于输入元素

Answer 3

最后我用过的是：

popup.html：

<input type="text" id="textbox" name="aName" value="" placeholder="blah" autofocus />

popup.js：

$(function() {              
    if (location.search != "?focusHack") location.search = "?focusHack";
});

Answer 4

Tarek El-Mallah重新加载弹出窗口的方法确实有效，它只是不适合你使用manifest_version：2和内联脚本是不允许的...
http://code.google.com/chrome/extensions/manifestVersion.html
此外，这是一个众所周知的问题.... http://code.google.com/p/chromium/issues/detail?id=111660
以下是适用于manifest_version的版本：2 .....

manifest.json

{
  "name": "Browser Action PopUp focus/tab test",
  "version": "1.0",
  "description": "A test to show that on opening a popup you cant set focus and the tab index is not honored on the first select.  See, http://stackoverflow.com/questions/9070727/tab-key-not-working-in-popup-in-chrome-extension.",
  "browser_action": {
      "default_title": "Browser Action PopUp focus/tab test.",
      "default_icon": "icon.png",
      "default_popup": "popup.html"
  },
  "manifest_version" :2
}

popup.html

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <script src="popup.js"></script>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Sample Extens</title>
</head>
<body style="padding: 0px; margin: 0px;" >
    <div id="Def">
        <input type="text" id="textbox" name="aName" value="" placeholder="blah" />
    </div>
</body>
</html>

popup.js

if (location.search !== "?foo") {
    location.search = "?foo";
    throw new Error; // load everything on the next page;
    // stop execution on this page
}

function onLoad() {
    document.getElementById("textbox").focus();
}

window.onload = onLoad;

Answer 5

试试这个：

 autofocus="autofocus"

您也可以尝试这样做：

setTimeout(
    function() { 
        if(location.search !== "?aName") {
           location.search = "?aName";
           throw new Error; 
        }
    }, 1000);

无法将焦点设置为在chrome扩展中输入
