代替函数，您必须编写如下的jquery代码。

Instead of function you have to write jquery code like below.

删除 函数submitContactForm（e）{}

添加 $ {document）.on（'submit'，'#myform'，function（e）{}）

$(document).on('submit', '#myform', function(e) {
    e.preventDefault();
    var reg = /^[A-Z0-9._%+-]+@([A-Z0-9-]+\.)+[A-Z]{2,4}$/i;
    var name = $('#inputName').val();
    var email = $('#inputEmail').val();
    if (name.trim() == '') {
        alert('Please enter your name.');
        $('#inputName').focus();
        return false;
    } else if (email.trim() == '') {
        alert('Please enter your email.');
        $('#inputEmail').focus();
        return false;
    } else if (email.trim() != '' && !reg.test(email)) {
        alert('Please enter valid email.');
        $('#inputEmail').focus();
        return false;
    } else {
        $('.submitBtn').prop("disabled", true);
        $('.modal-body').css('opacity', '.5');
        var myFormData = new FormData();
        e.preventDefault();
        var inputs = $('#myForm input[type="file"]');
        $.each(inputs, function(obj, v) {
            var file = v.files[0];
            var filename = $(v).attr("data-filename");
            var name = $(v).attr("name");
            myFormData.append(name, file, filename);
        });
        var inputs = $('#myForm input[type="text"],input[type="email"]');
        $.each(inputs, function(obj, v) {
            var name = $(v).attr("name");
            var value = $(v).val();
            myFormData.append(name, value);
        });
        var xhr = new XMLHttpRequest;
        xhr.open('POST', '<?php echo base_url(); ?>index.php/User/user_index_c/edit_profile_c/', true);
        xhr.send(myFormData);
        xhr.onload = function() {
            if (xhr.readyState === xhr.DONE) {
                if (xhr.status === 200) {
                    $('#inputName').val('');
                    $('#inputEmail').val('');
                    $('.statusMsg').html('<span style="color:green;">Changes have been saved successfully.</p>');
                    $('.submitBtn').removeAttr("disabled");
                    $('.modal-body').css('opacity', '');
                }
            }
        };
    }
});

让我知道它是否无效。
