IE没有提交我的表格输入按键回车键？

Question

我编写了自定义表单验证。验证工作正常所有浏览器，但当我按下回车键时IE不提交，如果用户输入正确的数据...点击按钮提交表格。我试图调试它，它在验证后返回true但不提交表单...

(function($){
$.fn.securityFramework = function() {
    var form = $(this);
    var $submitBtn = $('input.sf-submit');

    var errorClass = "error";
    var passClass = "pass";
    var MandatoryClass = "mandatory";
    //var $securityQuestions = $('.securityQuestions');

    // used in form submission
    var submitOK = false;
    var currentPWResult = true;
    var tcResult = true;

    //check username length
    var $userName = $('#userName',form);

    // create empty warning spans to stop focus issues in IE
    //displayResult($('input[type=text]', form), "","");
    //displayResult($('input[type=password]', form), "","");

    /* Registration form checks */
    // check user name for length and invaid characters
    $userName.keyup(function() {
        var userResult = minLength(6, $userName.val().length);
        var userNameResult =  validUserName($userName.val());
        if ( $(this).val() != "" ) {

            if ( userResult || userNameResult ) {
                if(userResult) {
                    //displayResult($(this), 'Please choose a longer username', errorClass);
                    $(this).focus();

您可以尝试：

$("form input").keypress(function (e) {
   if(e.which === 13) {
      $("form").submit();
   }
});
