尝试这样source,
form.submit(function(e) {
e.preventDefault();
$(this).find('[type=submit]').click();
$("form").submit();
})

尝试使用keydown而不是keypress:
$("forma1").keydown(function(event) {

你可以这样使用。它应该是这样Klikni();
而不是event.Klikni();
<script>
$("forma1").keypress(function(event) {
if (event.which == 13) {
Klikni(); //no need of event there..
}}
</script>

您只需在表单中添加onsubmit=return Klikni();
属性,在return false;
Klikni
功能中添加.keypress()
即可,而无需使用function Klikni(e) {
alert("Enter pressed");
return false;
}
。用户按Enter键提交的表单是默认行为。
<form name="forma1" action="#" id="forma1" onsubmit="return Klikni();">
Put your cursor into the field and press Enter.<br>
<input type="text">
</form>
&#13;
{{1}}&#13;
