Question

在我的meteor应用程序中，我正在使用一个需要查询的引导程序表。我运行了“meteor add query”，它列在“packages”文件中：

# Meteor packages used by this project, one per line.
#
# 'meteor add' and 'meteor remove' will edit this file for you,
# but you can also edit it by hand.

standard-app-packages
autopublish
insecure
reactive-dict
bootstrap
js-base-model
jquery
iron-router

文件（table.js）位于/ lib：

下

(function(){
    'use strict';
    var $ = jQuery;
    $.fn.extend({
        filterTable: function(){
            return this.each(function(){
                $(this).on('keyup', function(e){
                    $('.filterTable_no_results').remove();
                    var $this = $(this), search = $this.val().toLowerCase(), target = $this.attr('data-filters'), $target = $(target), $rows = $target.find('tbody tr');
                    if(search == '') {
                        $rows.show(); 
                    } else {
                        $rows.each(function(){
                            var $this = $(this);
                            $this.text().toLowerCase().indexOf(search) === -1 ? $this.hide() : $this.show();
                        })
                        if($target.find('tbody tr:visible').size() === 0) {
                            var col_count = $target.find('tr').first().find('td').size();
                            var no_results = $('<tr class="filterTable_no_results"><td colspan="'+col_count+'">No results found</td></tr>')
                            $target.find('tbody').append(no_results);
                        }
                    }
                });
            });
        }
    });
    $('[data-action="filter"]').filterTable(); 
})(jQuery);

$(function(){
    // attach table filter plugin to inputs
    $('[data-action="filter"]').filterTable();

    $('.container').on('click', '.panel-heading span.filter', function(e){
        var $this = $(this), 
                $panel = $this.parents('.panel');

        $panel.find('.panel-body').slideToggle();
        if($this.css('display') != 'none') {
            $panel.find('.panel-body input').focus();
        }
    });
    $('[data-toggle="tooltip"]').tooltip();
})

当我从app根目录运行meteor命令时，出现以下错误：

我该怎么做才能解决这个问题？

Answer 1

jQuery是一个仅限客户端的库，您不能在服务器端使用它 - 抛出此错误是因为jQuery未定义。要解决此问题，请将代码限制在客户端，方法是将其放在/client文件夹中（或/client/lib，如果您希望它在加载时具有优先级），或者将代码包装在

if (Meteor.isClient) {
  ...
}

meteor app - 无法查找查询
