jQuery 验证插件多种表单

Question

我正在尝试向一系列表单添加一些功能以验证两个复选框。我正在使用 jQuery 验证插件，但我一生都无法让它工作。在 fiddle 中，当我提交时，我只是收到一条 403 禁止消息。在我的实际网站上，它看起来甚至从未执行过。

HTML - 这些表单是多个且每页相同的。不过 Stackoverflow 只让我展示一个

<form method="post" id="offer" name="offer" action="#" class="offer">
    <input type="text" name="original_description">
    <input type="text" name="description">
    <input type="text" name="added_by">
    <input type="submit" id="add" value="add" class="submit">
</form>

JS

$(".offer").each(function () {
    $(this).validate({
        submitHandler: function (form) {
            var x = form.find('input[name=description]').val();
            var y = form.find('input[name=original_description]').val();
            var z = similar_text(x, y, 1);
            alert("Description: " + x + " original_description: " + y + " z: " + z)
            if (z > 50 && !isNaN(z)) {
                alert("Description too similar to original. Please make it less similar");
                return false;
            }
            form.submit();
        },
        rules: {
            added_by: {
                required: true
            }
        },
        messages: {
            added_by: {
                required: 'Please select your name'
            }
        }
    });
});

正如评论中所述，您应该在 rules: 之前添加一个“,”，并在您的submitHandler中操作jquery表单对象，如下所示:

$(".offer").each(function () {
    $(this).validate({
        submitHandler: function (form) {
            var x = $(form).find('input[name=description]').val();
            var y = $(form).find('input[name=original_description]').val();
            var z = similar_text(x, y, 1);
            alert("Description: " + x + " original_description: " + y + " z: " + z)
            if (z > 50 && !isNaN(z)) {
                alert("Description too similar to original. Please make it less similar");
                return false;
            }
            form.submit();
        },
        rules: {
            added_by: {
                required: true
            }
        },
        messages: {
            added_by: {
                required: 'Please select your name'
            }
        }
    });
});
