jq动态拼接html页面及数据

一、jq动态拼接html页面

需求:
1.页面内容不是死的
2.根据后台数据动态加载页面数据

实现:

在这之前我们需要了解下apppend()与html()这两个方法的区别:
简单来说就是append（）方法是在元素列表添加某个元素，但是html（）是替换元素中的数据。如果需要做换页，导航此类的效果最好使用html（）方法

详情可参考:append()与html()区别

废话不多说直接上代码:

1.首先在需要动态拼接的地方的父级标签可以加上一个id或者class类名区别倒是不大个人都是加className 如下(templateArea即是我们会在其下面拼接html页面及数据):

<body>
<div class="page"><div class="tab_line clearfix"><a class="tab_line_a" href="/reportPage?mainId=${mainId !}&year=${year !}&isFillIn=${mainId !}">医疗质量</a><a class="tab_line_a" href="/reportPageOperate?mainId=${mainId !}&year=${year !}&isFillIn=${isFillIn !}">运营效率</a><a class="tab_line_a now_a">持续发展</a><a class="tab_line_a" href="/reportPageSatisface?mainId=${mainId !}&year=${year !}&isFillIn=${isFillIn !}">满意度</a></div><div class="templateArea"></div><div class="bottom"><a href="/homepage" class="operation_line_button fr">返回</a><div class="operation_line_button operation_line_button_blue fr save">保存</div></div>
</div>
</body>

2.ajax获取到数据根据数据情况和需求可自主选择拼接流程以下为我个人需求拼接:
主要步骤为:
a.新建变量用来存放页面即:var list=""
b.将对应页面放到list中如需要放一个input 则为:list+=“input标签” 主要就是这种格式
c.最后就是$(".templateArea").append(list)

大概就是这三步但是需求都是不一样的所以说根据自己情况进行改动有这个思路就可

function getTemplateList(param) {jQuery.ajax({url: systemBaseInterface + "/sustainedAdd/findSustainedTemplateList",type: "POST",cache: false,async: false,data: param,dataType: "json",success: function (data, text) {var list = "";for (var i = 0; i < data.data.length; i++) {if (i == 0) {list += "<div class=\"content\">\n" +"                <div class=\"title\">" + data.data[i].content + "<span style=\"float: right\">" + ${year !} + "</span></div>\n" +"                <table class=\"content_table\">\n" +"                    <tr>\n" +"                        <th></th>\n" +"                        <th></th>\n" +"                        <th></th>\n" +"                        <th></th>\n" +"                    </tr>"} else {list += "<div class=\"content\">\n" +"            <div class=\"title\">" + data.data[i].content + "\n" +"            </div>\n" +"<table class=\"content_table functionalPositionArea\">\n" +"                <tr>\n" +"                    <th></th>\n" +"                    <th></th>\n" +"                    <th></th>\n" +"                    <th></th>\n" +"                </tr>"}jQuery.ajax({url: systemBaseInterface + "/sustainedAdd/findSustainedTemplateList",type: "POST",cache: false,async: false,data: {"parentCode": data.data[i].code},dataType: "json",success: function (data, text) {for (var j = 0;

这里是我的拼装代码我是分三种情况进行拼接的因需求而异 这种方法笨是笨了点不过身为后台开发的有时候想不到思路的话这种拼接倒也不失为一种解决方案

最后给大家看下效果:

我这里是先加载头信息 bb 然后加载的是三种不同的框(下拉框输入框两条件一结果框)

二、腾讯template封装数据

这里给大家扩展一个其他的封装数据的方法 template模板引擎框架这里是在腾讯template基础上使用些许改变

我用的是template-native-3.0.1.js 大家有兴趣可以找下源码看下
个人认为template用于这些table之类的循环是挺爽的(大佬勿喷)
使用如下:
1.首先 js获取到后台数据列表通过template进行封装

 user.userData = function (param) {return $.ajax({url: systemBaseInterface + "/base/userData",data: param,failed: function (code, msg) {DiaLogBox.error(msg);},success: function (data) {template.loadData("user", data.data, function (ele) {$(ele).show();user.tableInit();});$("#userlist").setPager(data.data, function () {user.userData(param);});}});};

2.然后在页面调用方法如下:
页面调用主要分为几步:
a.设置template-name="你在js中设置的名字"
b.循环数据(我这里的list是因为我是分页最后一层是list目录然后你们可以看数据情况进行循环)
c.放入数据即可

3.效果如下:

最后给大家放下template-native-3.0.1.js源码有兴趣看下:

!function () {function a(a) {return a.replace(t, "").replace(u, ",").replace(v, "").replace(w, "").replace(x, "").split(/^$|,+/)}function b(a) {return "'" + a.replace(/('|\\)/g, "\\$1").replace(/\r/g, "\\r").replace(/\n/g, "\\n") + "'"}function c(c, d) {function e(a) {return m += a.split(/\n/).length - 1, k && (a = a.replace(/\s+/g, " ").replace(/<!--.*?-->/g, "")), a && (a = s[1] + b(a) + s[2] + "\n"), a}function f(b) {var c = m;if (j ? b = j(b, d) : g && (b = b.replace(/\n/g, function () {return m++, "$line=" + m + ";"})), 0 === b.indexOf("=")) {var e = l && !/^=[=#]/.test(b);if (b = b.replace(/^=[=#]?|[\s;]*$/g, ""), e) {var f = b.replace(/\s*\([^\)]+\)/, "");n[f] || /^(include|print)$/.test(f) || (b = "$escape(" + b + ")")} else b = "$string(" + b + ")";b = s[1] + b + s[2]}return g && (b = "$line=" + c + ";" + b), r(a(b), function (a) {if (a && !p[a]) {var b;b = "print" === a ? u : "include" === a ? v : n[a] ?

三、总结

我们页面封装页面及数据的时候大部分时间其实还是页面不用动然后数据封装用循环遍历但是你顶不住需求怪呀但是拼接的话也不是很难就拿过来页面append()下就可以了学到三连哈~
