Disable enter submit
提问by user2288298
I have a form with a textfield inside and I am trying to disable the default behavior when the browser submits the whole form if the user presses Enterwhile the textfield is selected.
我有一个带有文本字段的表单，如果用户Enter在选择文本字段时按下，我试图禁用浏览器提交整个表单时的默认行为。
$('#recaptcha_response_field').keydown(function(event) { if (event.keyCode == 13) {
event.preventDefault();
event.stopPropagation();
event.stopImmediatePropagation();
alert("You Press ENTER key");
return false;
}
});
Currently am getting "You Press ENTER key" and the default behavior isn't overridden.
目前正在收到“您按 ENTER 键”并且默认行为未被覆盖。

To prevent the script from blocking the enter key on other elements such as on a textarea. Change the target from "form" to "input".
防止脚本阻止其他元素（例如文本区域）上的 Enter 键。将目标从“表单”更改为“输入”。
$(document).on("keypress", "input", function (e) {
var code = e.keyCode || e.which;
if (code == 13) {
e.preventDefault();
return false;
}

If none of the above solution is working for you , and you are using javascript anyway , why don't you use button type as 'button' <input type='button'>and submit it using javascript
如果上述解决方案都不适用于您，并且您仍然使用 javascript，为什么不使用按钮类型作为“按钮”<input type='button'>并使用 javascript 提交它
$('#form_id').submit();

U can use this script to prevent enter on entire from.
你可以使用这个脚本来防止整个输入。
<script type="text/javascript">
$(document).on("keypress", 'form', function (e) {
if (e.target.className.indexOf("allowEnter") == -1) {
var code = e.keyCode || e.which;
if (code == 13) {
e.preventDefault();
return false;
}
}
});
</script>
you put the classname to which control need to use enter
你把需要使用的控件的类名输入
