页面html代码：
<li><div class="coll-tit"><span class="coll-icon"><iclass="sysfont coll-default"></i>全域旅游目的地</span></div><div class="coll-panel"><div class="title-cont-two" style=" padding-top: 5px;padding-right: 5px;"><p><span>共</span><span>计<span id="globalTravelCount">XX</span>个</span></p><p class="this-title-two title-block mt-10" id="globalTravel"><a class="more" style="cursor: pointer;" id="globalTravelMore">查看更多<i class="sysfont"></i></a></p><div class="title-cont-two"></div></div></div></li>
发起ajax的js代码：
function loadMoreGlobalData() {var $parent_region = $("#parent_region").val();var $level = $("#level").val();var globalTravelCount = parseInt($("#globalTravelCount").text());var d = document.getElementById("globalTravel");var p1 = d.getElementsByTagName('span');var num = p1.length; // 得到目前已经显示的旅游目的地的数量var currentPage = Math.floor(num / 10); // 得到当前页数if (parseInt(num) >= globalTravelCount){// 已经显示全部数据$("#globalTravelMore").remove();}else {$.post("/globalTravel/more",{ parent_region:$parent_region,pageNum:currentPage,level:$level},function(backData,textStatus,ajax){if (textStatus == "success") {//遍历//返回json数组对象,对其遍历$.each(backData, function (i, json) {var $span = $("<span></span>");var $a = $("<a></a>")$a.attr('href','/data-check?parent_region='+json['region']+'&level='+json['level']);$a.text(json['name'])$span.append($a);$("#globalTravelMore").before($span);});// $("#globalTravelMore").appendTo("#globalTravel")var spanCount = document.getElementById("globalTravel").getElementsByTagName('span').length;if (parseInt(spanCount) >= globalTravelCount) {$("#globalTravelMore").remove();}}else {alert("ajax读取信息失败了！")}},"json");}}
给html代码中的a标签（查看更多）添加点击事件的js代码：
<script>$("#globalTravelMore").click(function () {loadMoreGlobalData()});</script>
