Question

我创建了以下JQuery脚本，它似乎适用于除IE 8之外的所有浏览器。当我查看Internet Explorers错误详细信息时，我根本没有得到任何错误详细信息。 IE只是指向我的JQuery文件而没有显示受影响的代码行。有什么建议？我使用的是JQuery 1.4.4版我的脚本在

下面

    $(document).ready(function() {

        $("input[name='emailAddress']").blur(function() {
            // Actual Email Validation function
            $('#emailMessage').html("");
            var hasError = false;
            var emailaddressVal = $("input[name='emailAddress']").val().trim();
            var invalidEmailAddresses = ['goddady.com', 'aol.com', 'yahoo.com', 'yahoo.fr'];

            if(!isValidEmailAddres(emailaddressVal)) {
                $("<span id='emailMessage' class='LV_validation_message LV_invalid'>The email provided does not contain an @ symbol</span>").insertAfter("input[name='emailAddress']");
                hasError = true;
            } else {
                emailaddressVal = emailaddressVal.split('@').slice(1)[0].trim();

                if($.inArray(emailaddressVal, invalidEmailAddresses) >= 0) {
                    $("<span id='emailMessage' class='validation'>The email provided is not from a business related domain. Please use an appropriate email address instead.</span>").insertAfter("input[name='emailAddress']");
                } else {
                    $('#emailMessage').css('display', 'none');
                }
            }
            if(hasError == true) {
                return false;
            }
        });

        function isValidEmailAddres(emailID) {
            var regexExp = new RegExp(/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i);
            return regexExp.test(emailID);
        }

    });

Answer 1

我怀疑.trim()因为＆lt; = IE8不支持。无论如何，当您使用jQuery时，最好还是使用jQuery.trim()。例如：

var emailaddressVal = $.trim($("input[name='emailAddress']").val());

JQuery脚本在IE中不起作用
