如何创建一个类似于链接的 HTML 按钮 [英] How to create an HTML button that acts like a link

问题描述

I would like to create an HTML button that acts like a link. So, when you click the button, it redirects to a page. I would like it to be as accessible as possible.

I would also like it so there aren't any extra characters, or parameters in the URL.

How can I achieve this?

---

Based on the answers posted so far, I am currently doing this:

<form method="get" action="/page2">
    <button type="submit">Continue</button>
</form>

but the problem with this is that in Safari and Internet Explorer, it adds a question mark character to the end of the URL. I need to find a solution that doesn't add any characters to the end of the URL.

There are two other solutions to do this: Using JavaScript or styling a link to look like a button.

Using JavaScript:

<button onclick="window.location.href='/page2'">Continue</button>

But this obviously requires JavaScript, and for that reason it is less accessible to screen readers. The point of a link is to go to another page. So trying to make a button act like a link is the wrong solution. My suggestion is that you should use a link and style it to look like a button.

<a href="/link/to/page2">Continue</a>

解决方案

HTML

The plain HTML way is to put it in a <form> wherein you specify the desired target URL in the action attribute.

<form action="https://google.com">
    <input type="submit" value="Go to Google" />
</form>

If necessary, set CSS display: inline; on the form to keep it in the flow with the surrounding text. Instead of <input type="submit"> in above example, you can also use <button type="submit">. The only difference is that the <button> element allows children.

You'd intuitively expect to be able to use <button href="https://google.com"> analogous with the <a> element, but unfortunately no, this attribute does not exist according to HTML specification.

CSS

If CSS is allowed, simply use an <a> which you style to look like a button using among others the appearance property (it's only not supported in Internet Explorer).

<a href="https://google.com" class="button">Go to Google</a>

a.button {
    -webkit-appearance: button;
    -moz-appearance: button;
    appearance: button;

    text-decoration: none;
    color: initial;
}

Or pick one of those many CSS libraries like Bootstrap.

<a href="https://google.com" class="btn btn-primary">Go to Google</a>

JavaScript

If JavaScript is allowed, set the window.location.href.

<input type="button" onclick="location.href='https://google.com';" value="Go to Google" />

Instead of <input type="button"> in above example, you can also use <button>. The only difference is that the <button> element allows children.
