How to create a HTML Cancel button that redirects to a URL

问题

I am playing with the Buttons in the w3schools Tryit editor, and I am trying to figure out how to make my browser redirect to an URL when I click on the "Cancel" button.

Here's what I have tried:

<form action="demo_form.asp" method="get">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <button type="submit" value="Submit">Submit</button>
  <button type="reset" value="Reset">Reset</button>
  <button type="cancel" onclick="javascript:window.location='http://stackoverflow.com';">Cancel</button>
</form>

But it doesn't work. Any ideas?

回答1:

cancel is not a valid value for a type attribute, so the button is probably defaulting to submit and continuing to submit the form. You probably mean type="button".

(The javascript: should be removed though, while it doesn't do any harm, it is an entirely useless label)

You don't have any button-like functionality though, so would be better off with:

<a href="http://stackoverflow.com"> Cancel </a>

… possibly with some CSS to make it look like a button.

回答2:

There is no button type="cancel" in html. You can try like this

<a href="http://www.url.com/yourpage.php">Cancel</a>

You can make it look like a button by using CSS style properties.

There are a few problems here.

First of all, there is no such thing as <button type="cancel">, so it is treated as just a <button>. This means that your form will be submitted, instead of the button taking you elsewhere.

Second, javascript: is only needed in href or action attributes, where a URL is expected, to designate JavaScript code. Inside onclick, where JavaScript is already expected, it merely acts as a label and serves no real purpose.

Finally, it's just generally better design to have a cancel link rather than a cancel button. So you can just do this:

<a href="http://stackoverflow.com/">Cancel</a>

With CSS you can even make it look the same as a button, but with this HTML there is absolutely no confusion as to what it is supposed to do.

回答4:

it defaults to submitting a form, easiest way is to add "return false"

<button type="cancel" onclick="window.location='http://stackoverflow.com';return false;">Cancel</button>

回答5:

<input class="button" type="button" onclick="window.location.replace('your_url')" value="Cancel" />

回答6:

Just put type="button"

<button type="button"><b>Cancel</b></button>

Because your button is inside a form it is taking default value as submit and type="cancel" doesn't exist.

There is no button type cancel https://www.w3schools.com/jsref/prop_pushbutton_type.asp

To achieve cancel functionality I used DOM history

<button type="button" class="btn btn-primary" onclick="window.history.back();">Cancel</button>

回答8:

<button onclick=\"window.location='{$_SERVER['PHP_SELF']}';return false;\">Reset</button>

Not enough rep to Vote Up for Kostyan. Here's my final solution (needed a reset button).

Thanks again to Kostyan for answering the question as asked without suggesting a "workaround" (time-consuming) method to "construct a button" with styles.

This is a Button (which the viewer expects to see) and it works exactly as requested. And it mingles with the other buttons on the page. Without complexity.

I did remove the "type=cancel" which apparently was useless. So even less code. :)

<a href="index.php"><button style ="position:absolute;top:450px;left:1100px;height:30px;width:200px;"> Cancel </button></a>

With Jquery:

$(".cancel-button").click(function (e) {
  e.preventDefault();
});
