加载页面时出现J-Query错误

Question

我在我的jquery文件中不断收到错误：“ Uncaught TypeError：无法调用null的方法'click'（匿名函数）jQuery.extend.ready DOMContentLoaded-第2行

jQuery代码：

  $(document).ready(function () {
      $(".leftImage a").click(function () {
          _gaq.push(['_trackEvent', 'sidebanner', 'click', $(this).attr('id'), 0, true]);
      }); //End Of SideBanners

      $("a[href$='.pdf'], area[href$='.pdf']").click(function () {
          if ($(this).attr("id")) {
              _gaq.push(['_trackEvent', 'pdf', 'click', $(this).attr('id'), 0, true]);
          } else {
              _gaq.push(['_trackEvent', 'pdf', 'click', $(this).attr('href'), 0, true]);
          }
      }); //End of pdfs mapping and non mapping

      $("a[href$='.zip']").click(function () {
          if ($(this).attr("id")) {
              _gaq.push(['_trackEvent', 'zipfile', 'download', $(this).attr('id'), 0, true]);
          } else {
              _gaq.push(['_trackEvent', 'zipfile', 'download', $(this).attr('href'), 0, true]);
          }
      }); //End of Zips

  });

似乎是冲突，您可以使用http://api.jquery.com/jquery.noconflict/提供的解决方案进行解决

jQuery.noConflict();

(function( $ ) {

  $(document).ready(function() {

        $(".leftImage a").click(function () {
            _gaq.push(['_trackEvent', 'sidebanner', 'click', $(this).attr('id'), 0, true]);
        }); //End Of SideBanners

        $("a[href$='.pdf'], area[href$='.pdf']").click(function () {
            if ($(this).attr("id")) {
                _gaq.push(['_trackEvent', 'pdf', 'click', $(this).attr('id'), 0, true]);
            } else {
                _gaq.push(['_trackEvent', 'pdf', 'click', $(this).attr('href'), 0, true]);
            }
        }); //End of pdfs mapping and non mapping

        $("a[href$='.zip']").click(function () {
            if ($(this).attr("id")) {
                _gaq.push(['_trackEvent', 'zipfile', 'download', $(this).attr('id'), 0, true]);
            } else {
                _gaq.push(['_trackEvent', 'zipfile', 'download', $(this).attr('href'), 0, true]);
            }
        }); //End of Zips

  });

})(jQuery);

希望这可以帮助！
