jQuery:防止默认的浏览器表单提交行为，但使用jQuery提交表单? [英] jquery: prevent default browser form submit behaviour but submit form with jquery?

问题描述

$('#search_form').submit(function(e) {
    //e.preventDefault();
    return false;
})

这很好，可以防止在按Enter键时提交表单.

This works just fine to prevent form submission when pressing Enter.

但是即使在某些情况下，我也想使用jquery提交表单.

However even I have this I want to submit the form with jquery if certain circumstances are true.

$('#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
        }

    }

如果我按Enter键，则不会提交表单，但是会在控制台中登录！

If I press enter the form doesn't get submitted, but the log in in the console happens!

推荐答案

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

   }
})
