如果第一次提交表单,则不会触发jQuery validate方法

所以,我正在创建一个使用jQuery validate作为基础的自定义插件。我的想法是创建一个插件,它将验证任何正常形式,而无需为所有这些创建单独的Jquery Validate设置。这是我的代码

HTML

<form role="form" class="form-horizontal form-validate" id="" action="/action/action.users.php">
    <div class="box-body">
        <h4>Account Information</h4>
        <div class="form-group">
            <label class="col-sm-3 control-label">test</label>
            <div class="col-sm-9 controls">
                <div class="row">
                    <div class="col-xs-12">
                        <input name="txt_username" class="form-control" placeholder="Username"  value="" type="text" data-required="true">
                    </div>
                </div>
            </div>
        </div>

        <div class="form-group">
            <label class="col-sm-3 control-label">test2</label>
            <div class="col-sm-9 controls">
                <div class="row">
                    <div class="col-xs-12">
                        <input name="txt_password" class="form-control" placeholder="Password" value="" type="text" data-required="true">
                    </div>
                </div>
            </div>
        </div>
    </div>
    <div class="box-footer">
        <button class="btn btn-sm btn-primary" type="submit">Submit</button>
        <button class="btn btn-sm btn-warning" type="reset">Reset</button>
    </div>
</form>

js

(function ( $ ) {
    $.fn.validate_form = function(options) {
        var settings = $.extend({
                action: "/",
                redirect: "",
                notification: "",
            }, options 
        );

        var $this = this;
        var post_data = {};
        var post_response = "default";

        /* if first submit, it wont trigger this, succeeding submits, it will run this */
        $this.validate({
            submitHandler:function(){
                $this.find(':input[type="text"],:input[type="radio"],:input[type="password"],:input[type="email"]').each(function(){
                    element = $(this);
                    var name = element.attr('name');
                    var val = element.val();

                    if(element.is(':radio')) {
                        if(element.is(':checked')) 
                            post_data[name]  = val;
                    }
                    else post_data[name]  = val;
                });

                console.log(post_data);

                $.post( settings.action, post_data, function(result){
                    post_response = result;
                    console.log(result);
                });
            }
        });
        /*end if first submit, it wont trigger this */

        $this.find('[data-required="true"]').each(function(){
            $(this).rules("add",{
                required: true
            });
        }); 

        return post_response;
    }
}( jQuery ));

$(document).ready(function() {
    $(".form-validate").submit(function(e){
        var action = $(this).attr("action");
        var result = $(this).validate_form({
            action:action
        });
        e.preventDefault();
    });
});

它正在工作,除非,如果表单是第一次提交,验证将不起作用,但是,如果我再次提交,它现在将正常工作。我似乎无法找到问题因为firebug没有错误。任何帮助将不胜感激

.validate()方法仅用于 初始化 插件。它不应该包含在.submit()处理程序中,而且这是解决问题的关键。
