Prevent users from submitting a form by hitting Enter

Question

I have a survey on a website, and there seems to be some issues with the users hitting enter (I don\'t know why) and accidentally submitting the survey (form) without clicki

Answer 1

Disallow enter key anywhere

If you don't have a </code> in your form, then just add the following to your <code><form></code>:</p> <pre><code><form ... onkeydown="return event.key != 'Enter';"> </code></pre> <p>Or with jQuery:</p> <pre><code>$(document).on("keydown", "form", function(event) { return event.key != "Enter"; }); </code></pre> <p>This will cause that every key press inside the form will be checked on the <code>key</code>. If it is not <code>Enter</code>, then it will return <code>true</code> and anything continue as usual. If it is <code>Enter</code>, then it will return <code>false</code> and anything will stop immediately, so the form won't be submitted.</p> <p>The keydown event is preferred over keyup as the <code>keyup</code> is too late to block form submit. Historically there was also the keypress, but this is deprecated, as is the KeyboardEvent.keyCode. You should use KeyboardEvent.key instead which returns the name of the key being pressed. When <code>Enter</code> is checked, then this would check 13 (normal enter) as well as 108 (numpad enter).</p> <p>Note that <code>$(window)</code> as suggested in some other answers instead of <code>$(document)</code> doesn't work for <code>keydown</code>/<code>keyup</code> in IE<=8, so that's not a good choice if you're like to cover those poor users as well.</p> <h2>Allow enter key on textareas only</h2> <p>If you have a <code><textarea></code> in your form (which of course <em>should</em> accept the Enter key), then add the keydown handler to every individual input element which isn't a <code><textarea></code>. </p> <pre><code><input ... onkeydown="return event.key != 'Enter';"> <select ... onkeydown="return event.key != 'Enter';"> ... </code></pre> <p>To reduce boilerplate, this is better to be done with jQuery:</p> <pre><code>$(document).on("keydown", ":input:not(textarea)", function(event) { return event.key != "Enter"; }); </code></pre> <p>If you have other event handler functions attached on those input elements, which you'd also like to invoke on enter key for some reason, then only prevent event's default behavior instead of returning false, so it can properly propagate to other handlers.</p> <pre><code>$(document).on("keydown", ":input:not(textarea)", function(event) { if (event.key == "Enter") { event.preventDefault(); } }); </code></pre> <h2>Allow enter key on textareas and submit buttons only</h2> <p>If you'd like to allow enter key on submit buttons <code><input|button type="submit"></code> too, then you can always refine the selector as below.</p> <pre><code>$(document).on("keydown", ":input:not(textarea):not(:submit)", function(event) { // ... }); </code></pre> <p>Note that <code>input[type=text]</code> as suggested in some other answers doesn't cover those HTML5 non-text inputs, so that's not a good selector.</p> </p> <div class="appendcontent"> </div> </div> <div class="jieda-reply"> <span class="jieda-zan button_agree" type="zan" data-id='20155'> <i class="iconfont icon-zan"></i> <em>0</em> </span> <span type="reply" class="showpinglun" data-id="20155"> <i class="iconfont icon-svgmoban53"></i> 讨论(0) </span> <div class="jieda-admin"> </div> <div class="noreplaytext bb"> <center><div> <a href="https://www.e-learn.cn/qa/q-10918.html"> 查看其它30个回答 </a> </div></center> </div> </div> <div class="comments-mod " style="display: none;
