Question

我有一个jQuery函数，我想只在表单验证为真时才执行我有验证和其他jQuery工作正常。
问题是现在验证和其他功能都在同一时间执行。
我想仅在表单验证为真时才运行其他函数。这是我的剧本

<script>
            $(document).ready(function () {
                $.validator.addClassRules({
                    fileName: {
                        required: true
                    }
                });
                $("#myform").validate();
                if ($("#myform").valid()) {
                    $(function () {
                        $('#myform').submit(function () {
                            var cboxes = ($('input:checkbox:checked').filter(":checked").length);
                            var nboxes = ($(":checkbox:not(:checked)").length);
                            if ((cboxes > 0) && (nboxes > 0)) {
                                confirm('You have Checked only few locations among the List. \n Are you sure, you do not want to Prescribe from the other locations? ');
                            } else if (cboxes == 0) {
                                alert('Please select atleast One Address \n Where you would prefer to prescribe from.');
                                return false;
                            }
                            else {
                                return true;
                            }
                        });
                    });
                }
            });
</script>

请告知我该如何完成这项工作？

Answer 1

如果你正在使用jQuery validate插件，那么valid()方法会返回一个布尔值来指示表单是否成功验证，所以你可以这样做：

if ($("#myform").valid()) {
    CallSomeOtherFunction();
}

Answer 2

如果您使用standard plugin，则应支持此类代码：

$(document).ready(function() {
    $("#myForm").validate({ 
        submitHandler: function(form) {
            SomeFuncHere();
        }
    });
})

成功验证后，应调用submitHandler中的代码。

编辑：根据您的代码，请尝试以下方式：

$("#myform").validate({ 
    submitHandler: function(form) {
        var cboxes = ($('input:checkbox:checked').filter(":checked").length);
        var nboxes = ($(":checkbox:not(:checked)").length);
        var flag = false;
        if ((cboxes > 0) && (nboxes > 0)) {
            flag = confirm('You have Checked only few locations among the List. \n Are you sure, you do not want to Prescribe from the other locations? ');
        } else if (cboxes == 0) {
            alert('Please select atleast One Address \n Where you would prefer to prescribe from.');
        }
        else {
            flag = true;
        }
        return flag;
    }
});

您必须使用.validate().form()

if (!$("#myform").validate().form()) {
    return false; //doesn't validate
}else
{
    //form is validated do your work
}

jQuery如果myform.valid（）为true则触发另一个jQuery函数？
