如何在HTML页面上使用此JavaScript？
[英]How to use this javascript on HTML page?
问题描述
So I have been getting help from some as to how I could fix the issue about how I want to be able to click a button, and have it instead auto select the search box on my site. 
所以我一直在寻求一些关于如何解决我希望如何能够点击按钮的问题的帮助，并让我自动选择我网站上的搜索框。
Well, people are telling me to use Javascript for the click to do it and I was told to use this code: 好吧，人们告诉我使用Javascript进行点击，我被告知要使用这段代码：
function setFocus() {
document.getElementById("myTextbox").focus();
}
But I don't know how to properly combine it with my html. 但我不知道如何正确地将它与我的HTML结合起来。 Looked around on Google and everything isn't piecing together for me.. 环顾谷歌，一切都没有为我拼凑..
My HTML: 我的HTML：

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" type="text/css" href="main.css">
<script type="text/javascript">
function setFocus() { document.getElementById("search").focus(); }
</script>
</head>
<body>
<div class="my_container cf">

try 尝试
onClick="javascript:setFocus();" // no parameter
or more simply 或者更简单
onClick="setFocus();" // no parameter
BTW, you should be setting the focus on the input tag not the form , so change the id of the input tag to be id="search" and of course remove it from the form . 顺便说一句，您应该将焦点设置在输入标记而不是form ，因此将输入标记的id更改为id="search" ，当然将其从form删除。

instead of calling setFocus(search) 而不是调用setFocus(search)
have you tried calling only setFocus() 你试过只调用setFocus()吗？
in 在
`<div class="headerbuttons"><p style="text-decoration: none;color:#000000;padding:3px;display:block;"
onClick="setFocus(search);">CAN'T FIND A FILE?</p></div>`
EDIT: 编辑：
remove id = search from the form element and set it on the text element 从form元素中删除id = search并将其设置在text元素上
<form method="get" action="/search" >
<input name="q" type="text" size="40" placeholder="Search for a DLL" id="search" />
</form>

onClick="setFocus(search);
remove "search" inside the braces 删除大括号内的“搜索”
set id="search" for text field 为文本字段设置id="search"

You were not calling the function setFocus(). 你没有调用函数setFocus（）。 Also, there was no ID assigned to the textbox. 此外，没有为文本框分配ID。
HTML: HTML：
<input name="q" id="search_box" type="text" size="40" placeholder="Search for a DLL" />
Javascript: 使用Javascript：
document.getElementById("search_box").focus();
