我有live score网站，它不是基于wordpress的，我为纯php网站构建了一个小部件，但现在我想向wordpress用户提供这个小部件。问题是，当我尝试这个小部件时，我出现了三个错误，老实说，我不是wordpress专家，所以我希望在这里得到帮助。这是我的用户链接：

<div id="widget-container" class="my_widget" name=\'15\' width="800px"></div>
<script src="http://skormix.com/mywidget/widget.js" type="text/javascript"></script>

下面是错误：

未捕获引用错误：$未定义未捕获引用错误：jQuery未定义未捕获类型错误：无法调用未定义的方法“ajax”，这是我的小部件代码的一部分：

(function() {

// Localize jQuery variable
var jQuery;

/******** Load jQuery if not present *********/
if (window.jQuery === undefined || window.jQuery.fn.jquery !== \'1.8.3\') {
    var script_tag = document.createElement(\'script\');
    script_tag.setAttribute("type","text/javascript");
    script_tag.setAttribute("src",
        "http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js");
    var script_tag1 = document.createElement(\'script\');
    script_tag1.setAttribute("type","text/javascript");
    script_tag1.setAttribute("src",
        "http://localhost/aaa/include-js/jquery_timer.js");

    if (script_tag.readyState) {
      script_tag.onreadystatechange = function () { // For old versions of IE
          if (this.readyState == \'complete\' || this.readyState == \'loaded\') {
              scriptLoadHandler();
          }
      };
    } else { // Other browsers
      script_tag.onload = scriptLoadHandler;
    }
    // Try to find the head, otherwise default to the documentElement
    (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
    (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag1);
} else {
    // The jQuery version on the window is the one we want to use
    jQuery = window.jQuery;
    main();
}

/******** Called once jQuery has loaded ******/
function scriptLoadHandler() {
    // Restore $ and window.jQuery to their previous values and store the
    // new jQuery in our local jQuery variable
    jQuery = window.jQuery.noConflict(true);
    // Call our main function
    main(); 
}

/******** Our main function ********/
function main() {
    jQuery(document).ready(function($) {
    /******* Load CSS *******/
    var css_link = $("<link>", { 
            rel: "stylesheet", 
            type: "text/css", 
            href: "http://localhost/aaa/widget/blue.css"
        });
        css_link.appendTo(\'head\');
        var txt;
        txt=\'<div id="wrapper">\';
        txt=txt+\'<ul class="tabs">\';
        txt=txt+\'<li id="fixtures_tab"><a href="#fixtures">Hepsi</a></li>\';
        txt=txt+\'<li id="live_tab"><a href="#live">Canlı</a></li>\';
        txt=txt+\'<li id="finished_tab"><a href="#finished">Bitmiş</a></li>\';
        txt=txt+\'<li id="program_tab"><a href="#program">Başlamamış</a></li>\';
        txt=txt+\'<li id="postpond_tab"><a href="#postpond">Ertelenen</a></li>\';
        txt=txt+\'<li id="selected_tab"><a id="f" href="#fav">Oyunlarım (0)</a></li>\';
        txt=txt+\'</ul>\';
        txt=txt+\'<div class="tab-container">\';
        txt=txt+\'<div id="fixtures" class="tab-content"><script type="text/javascript">get_All_Today_Matches();</script></div>\';
        txt=txt+\'<div id="live" class="tab-content"><script type="text/javascript"></script></div>\';
        txt=txt+\'<div id="finished" class="tab-content"><script type="text/javascript"></script></div>\';
        txt=txt+\'<div id="program" class="tab-content"><script type="text/javascript"></script></div>\';
        txt=txt+\'<div id="postpond" class="tab-content"><script type="text/javascript"></script></div>\';
        txt=txt+\'<div id="fav" class="tab-content"><script type="text/javascript"></script></div>\';
        txt=txt+\'</div>\';
        txt=txt+\'</div>\';
        $(\'#widget-container\').html(txt);
    });
}
})(); // We call our anonymous function immediately

对于第三个错误，我使用了如下ajax请求：

function get_All_Today_Matches()//this function used to get all the matches of today for all countries & comptions (live, finished, program) on the main page
{
    $.ajax({//ajax function to get the xml data (faster)
    type: "POST",//we use POST method beacuse we should send a \'home\' to the proxy page to get the right xml url
    url: "http://localhost/aaa/proxy.php",//proxy page
    data : {country : \'home\'},//parameters
    dataType: "xml",//returned data type
    success: parseToday//the function on success
 });
}

编辑：4。未捕获的TypeError：对象[对象对象]的属性“$”不是函数

add_action( \'init\', \'enqueue_skormix_widget_js\', 20 );

function enqueue_skormix_widget_js() {
  wp_enqueue_script(
    \'skormix-widget\',
    \'http://skormix.com/mywidget/widget.js\',
    array( \'jquery\' ),
    false,
    true
  );
}
