不知道为什么这不起作用。我相信你们都知道我在这里想要达到的目标。

当脚本运行时，我得到一个参考Uncaught TypeError: undefined is not a function，jquery.validate.js line:366它引用了这段代码：

function delegate( event ) {
            var validator = $.data( this[ 0 ].form, "validator" ),
                eventType = "on" + event.type.replace( /^validate/, "" ),
                settings = validator.settings;
            if ( settings[ eventType ] && !this.is( settings.ignore ) ) {
                settings[ eventType ].call( validator, this[ 0 ], event );
            }
        }                           ^^^^ HERE

我正在使用codeigniter2框架，因此如果我的表单页面对某些人没有意义，则表示歉意。

new_page.php（相关位）

<?php echo form_open(site_url('admin/manage_pages/new_page'),
                            array('id' => 'new-page-form')) . PHP_EOL; ?>
    <div class="form-group">
        <?php echo form_label('Page Title', 'page-title',
                                'class="control-label"') . PHP_EOL; ?>
        <?php echo form_input(array(
                                'name' => 'page-title',
                                'id' => 'input-page-title',
                                'max-length' => '255',
                                'placeholder' => 'Enter Page Title',
                                'class' => 'form-control')) . PHP_EOL; ?>
    </div><!-- /.form-group -->
    <div class="form-group">
        <?php echo form_label('Url', 'slug', 'class="control-label"'); ?>
        <span id="input-slug-span" class="form-control">
            <span id="input-slug-static"><?php echo site_url(); ?></span>
            <?php echo form_input(array(
                                    'name' => 'slug',
                                    'id' => 'input-slug')); ?>
        </span>
    </div><!-- /.form-group -->

并在new_page.validation.js中

$(document).ready(function() {

    //--------------------------------------------------------------------------------------
    //
    //  New Page Client Side Validation
    //
    //--------------------------------------------------------------------------------------

    $('#new-page-form').validate({

        onkeyup:true,

        rules: {
            'page-title': {
                required: true,
                remote: { 
                    url: 'new_title_exists',
                    type: 'post',
                    data: {
                        'page-title': function() { return $("#input-page-title").val(); }
                    }
                }
            },
            'slug': {
                required: true,
                remote: {
                    url: 'new_slug_exists',
                    type: 'post',
                    data: {
                        'slug': function() { return $('#input-slug').val(); }
                    }
                }
            }
        },
        messages: {
            'page-title': {
                required: 'Page Title is required.',
                remote: 'Page Title must be unique.'
            },
            'slug': {
                required: 'A URL slug is required',
                remote: 'The URL must be unique.'
            }
        }
    })
})

任何帮助将不胜感激！欢呼的家伙
