如何在加载网站后重点关注输入字段？

I have a very simple one page website that has a input field in it. I want to make the input field focused when the window/site is loaded so that the user/visitor can start typing on it right away the site is loaded!

我有一个非常简单的单页网站,里面有一个输入字段。我想在加载窗口/站点时使输入字段成为焦点,以便用户/访问者可以立即开始在网站上键入内容!

I want it NOT IN JQUERY. IF POSSIBLE PLEASE GIVE ME A SOLUTION IN JAVASCRIPT PLEASE.

我想要它不是在观察。如果可能请给我JAVASCRIPT的解决方案请。

Thanks in advance.

提前致谢。

There is a new input field attribute call autofocus. Supported by all browsers except IE http://www.html5tutorial.info/html5-autofocus.php

有一个新的输入字段属性调用自动对焦。除了IE http://www.html5tutorial.info/html5-autofocus.php之外的所有浏览器都支持

You can use that and provide fallback with the solutions others are providing

您可以使用它并使用其他人提供的解决方案提供后备

var i = document.createElement('input');
if(!('autofocus' in i)) {
   window.onload=function(){
    document.getElementById('ID').focus();
   });
}

#2

window.onload=function(){
    document.getElementById('ID').focus();
});

#3

//ID is the id of textbox

// ID是文本框的id

document.getElementById('ID').focus();

#4

document.getElementById("ControlID").focus();

#5

Add it to the onLoad callback so that it will focus after the page has been loaded:

将它添加到onLoad回调中,以便在页面加载后它将聚焦:

<body onLoad="function() { document.getElementById('input_field_id').focus(); }">

You need to use focus() method in javascript.

你需要在javascript中使用focus()方法。

In body onload method, call the javascript method, where you need to set the focus on the input field.

在body onload方法中,调用javascript方法,您需要在输入字段上设置焦点。

<script type="text/javascript">
function load()
{
   document.getElementById("inputFieldId").focus();
}
</script>
<body onload="load()">
