为什么我会收到JavaScript参考错误？

这是代码。我已经在PHP文件中的javascript中实现了一个功能。

  function getGeneratedLink(){
 alert("hi");
    $('#generateLinkModal').show();
    $('.generated_link_section').slideDown("fast");
    $('.generated_link_section').show();
$("#generateLinkModal div.modal-body span.message").hide();
$("#generateLinkModal div.modal-body input").hide();
$("#generateLinkModal div.modal-body span.loader-gif").show();

$.ajax({
    type:       "POST",
    url:        <?php echo $this->createUrl('admin/generateLink') ?>,
    data:       {},
    async:      false,
    dataType:   "json",
    success:    function(data) {
                    $("#generateLinkModal div.modal-body span.loader-gif").hide();
                    if (!data['session']) {
                        $('.generated_link_section').slideUp('fast', function(){
                            alert(data['session_msg']);
                            window.location = data['url'];
                        });
                    } else if (!data['success']) {
                        $("#generateLinkModal div.modal-body span.message").text(data['error_msg']);
                        $("#generateLinkModal div.modal-body span.message").show();
                    } else {
                        $("#generateLinkModal div.modal-body input").val(data['link']);
                        $("#generateLinkModal div.modal-body input").show();
                    }
                }
});

 }

稍后，我将对此函数进行调用，就像这样，不包含html标签

onclick="getGeneratedLink()">New Registration Link</button></a></li>

它显示了参考错误，脚本标签之间很好地包含了功能。

我尝试了几种函数调用的变体..没有成功的结果..

我不知道，是什么导致此错误
