对照着jquery来学vue.js系列之配合thinkphp下拉获取分页数据
上篇文章介绍了vue.js如何ajax获取数据；
接着不可避免就遇到的是；
如何进行数据分页呢？
这里以thinkphp为示例讲解；其他场景性质一样；
示例项目：http://git.oschina.net/shuaibai123/thinkphp-bjyadmin
示例链接：localhost/Home/Vue/web_page
项目中有张表province_city_area；
里面是全国的3000多个城市；这里就拿它做分页了；
一：thinkphp获取分页数据/Application/Home/Controller/VueController.class.php /** * 配合thinkphp分页示例 */ public function page(){ // 获取总条数 $count=M('Province_city_area')->count(); // 每页多少条数据 $limit=100; $page=new \Org\Nx\Page($count,$limit); $data=M('Province_city_area') ->limit($page->firstRow.','.$page->listRows) ->select(); echo json_encode($data); }二：前端接收数据的核心部分；
要实现的是移动端往那种下拉就加载数据的效果；
首先是先用ready方法加载第一页的数据显示到页面中；
设置一个变量i=1；var vm=new Vue({ el: '.box', data: { city: [] }, ready: function(){ this.$http.get(url).then(function(response){ this.city=response.data; }) }, })然后呢；判断当滚动轴到底部的时候；
让i+1 作为get参数中的页数；
加载下一页的数据；并追加到city中；i++ vm.$http.get(pageData.url+'/p/'+pageData.i).then(function(response){ // 用concat把下一页的数据追加到city中 vm.city=vm.city.concat(response.data); })三：完整的html；
/tpl/Home/Vue/web_page.html<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Vue 配合thinkphp分页示例</title> </head> <body> <div> {{item.name}} </div> No data <vue /> <script> //Get the url of the data var pageData={ URL: "{:U('Home/Vue/page')}", i: 1, height: 0, Over: false } var vm=new Vue({ el: '.box', Data: { City: [] }, ready: function(){ This.$http.get(pageData.url).then(function(response){ This.city=response.data; }) }, }) //Get the current position of the scroll bar function getScrollTop() { var scrollTop=0; If(document.documentElement && document.documentElement.scrollTop){ scrollTop=document.documentElement.scrollTop; }else if(document.body) { scrollTop=document.body.scrollTop; } Return scrollTop; } //Get the height of the current visual range function getClientHeight() { var clientHeight=0; If(document.body.clientHeight && document.documentElement.clientHeight){ clientHeight=Math.min(document.body.clientHeight, document.documentElement.clientHeight); }else{ clientHeight=Math.max(document.body.clientHeight, document.documentElement.clientHeight); } Return clientHeight; } //Get the complete height of the document function getScrollHeight() { Return Math.max(document.body.scrollHeight, document.documentElement.scrollHeight); } //Add loading style function addLoading(){ var loading=document.createElement('p'); Loading.className='loading' Loading.innerHTML='Loading...'; Document.body.appendChild(loading); } //Delete loading style function removeLoading(){ var loading=document.querySelector('.loading'); Loading.parentNode.removeChild(loading); } // Change Loading to No Data function loadingToOver(){ var loading=document.querySelector('.over'); Loading.style.display='block'; } //Listen to scroll events window.onscroll=function () { If (pageData.over) { return return false; } If (getScrollHeight()-(getScrollTop()+getClientHeight())<=50) { // Number of pages +1 pageData.i++ //Show loading addLoading(); // Get the data on the next page vm.$http.get(pageData.url+'/p/'+pageData.i).then(function(response){ removeLoading(); If(response.data.length==0){ pageData.over=true; loadingToOver(); }else{ vm.city=vm.city.concat(response.data); } }) } } </script> </body> </html>This has simply implemented the function of drop-down loading data;
Don’t be scared by the long code above;
More of them use native js to implement scroll axis monitoring events;
Just design the loading and loading styles according to the business;

Got it; I’ve been very out of sorts recently due to some things;
