jquery: prevent default browser form submit behaviour but submit form with jquery?
提问by matt
$('#search_form').submit(function(e) {
//e.preventDefault();
return false;
})
This works just fine to prevent form submission when pressing Enter.
这可以很好地防止按 Enter 时提交表单。
However even I have this I want to submit the form with jquery if certain circumstances are true.
但是，即使我有这个，如果某些情况属实，我也想用 jquery 提交表单。
edit:
编辑：
$('#search_form').submit(function(e) {
return !!e.submit;
});
function ...
if (e.keyCode == 13) {
if (blablabla) {
... // do something
} else {
$('#search_form').submit({submit:true}); //doesn't work
console.log('submitted'); //this does successfully get fired
}
}
If I press enter the form doesn't get submitted, but the log in in the console happens!
如果我按回车，表单不会被提交，但会在控制台中登录！

$('#search_form').submit(function(e) {
if($('.errors').is(':visible')){
e.preventDefault();
// do something else here// some errors are visible :)
return false;
}else{
}
})

By checking the type of e.originalEventwe can determine if human (type object) or script (type undefined) submitted the form:
通过检查的类型，e.originalEvent我们可以确定是人（类型对象）还是脚本（类型未定义）提交了表单：
$('#search_form').submit(function(e) {
if (typeof e.originalEvent !== 'undefined') {
e.preventDefault();
}
})
Invoke a jquery trigger to submit the form:
调用一个 jquery 触发器来提交表单：
$('#search_form').trigger('submit');
