我使用在这里找到的 jquery 验证插件

我的问题是，在表单中，如果我将提交按钮从

<input type="submit" value="Add" class="add" id="addbutton">

至

<input type="button" value="Add" class="add" id="addbutton">

该表格将无法验证或工作。

我想使用button而不是submit，因为如果用户关闭了 javascript，则表单根本不会提交。它只会坐在那里无所事事。

知道如何解决这个问题并让它在什么时候起作用type="button"

我相信验证插件实际上会在提交表单时进行验证。因此，您只需要使用 javascript 对按钮进行任何点击即可提交表单。像这样的东西：

$('#commentForm input[type=button]').click(function(){
  $(this).closest('form').submit()
});

附加：您还需要记住，在专注于任何表单元素时按 Enter 仍将提交表单，除非您禁用它，因此您在禁用 javascript 时仅删除提交按钮的解决方案不会涵盖这种情况。

你可以试试这个方法

    $('document').ready(function(){
    $('form').validate({
        rules: {
           a: {required:true, minlength:2}
        },      
        messages: {
           a: {required: "enter your name!"}       
        },


    });
    $('#checkbut').click(function(){
        $("form").validate().element("#a");
    });
});

工作演示
