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.
回答7:
Thats what i am using try it.
<a href="index.php"><button style ="position:absolute;top:450px;left:1100px;height:30px;width:200px;"> Cancel </button></a>
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. :)
回答9:
Here, i am using link in the form of button for CANCEL operation.
<button><a href="main.html">cancel</a></button>
回答10:
With Jquery:
$(".cancel-button").click(function (e) {
e.preventDefault();
});
