我有一个打开提示符的按钮：
$('#enter-manual-date').click(function(){
var date = prompt("Enter the date", "");
if(date != null && moment(date, 'DD-MM-YYYY', true).isValid()){
$('#exp').val(date);
}else{
$('#exp').val('');
alert("Invalid Date! Format should be: DD-MM-YYYY");
}
});
但问题是，即使对话框仍然没有任何输入，当我按Enter键时，它会自动提交表单。
我已经在输入时阻止表单提交：
$(function(){
$("form").bind("keypress", function (e) {
if (e.keyCode == 13) {
return false;
}
});
});
我也试图阻止默认：
e.preventDefault();
这是HTML。当您单击＆＃34;添加文档＆＃34;它会提交表单。按钮：

但它也不起作用。有什么想法吗？

让我们尝试以下方法：
$('myform').submit(function(e) {
e.preventDefault();
});
而不是
$(function(){
$("form").bind("keypress", function (e) {
if (e.keyCode == 13) {
return false;
}
});
});

确定。所以问题一直是＆＃34;手动输入＆＃34;按钮实际上是触发提交。因此，当您单击该按钮时，它会立即触发提交。但是，由于我显示提示，提交会中断，直到提示关闭。或者在提示符上按Enter键会触发要提交的表单。
