Summary of the use of javascript front-end template engine framework artTemplate - CSDN Blog
artTemplate is Tencent's open source front-end template framework. It is similar to mustache and handlerbars. It can be easily used in web projects and is quick to get started. If you have used mustache, you can almost quickly switch to the template framework.
Learning process:
1. Syntax introduction:
Data binding: similar to angularjs, except that the view and model are separate For directional binding, the model changes and the view changes, but not the other way around.
<script id="tpl1" type="text/template">
<h1 id="data-nbsp-mapping-nbsp-example">1、data mapping example</h1>
<h2 id="message">{{message}}</h2>
</script>
//js中使用模板渲染
var data1 = {message:"hello,artTemplate is a javasript framework."};
$("node1").innerHTML = template("tpl1",data1);Conditional judgment: A single if is supported here, and an else branch can also be added. There is no else if branch.
{{if isShow}}
<h3 id="满足条件展示消息-message">(2、满足条件展示消息：{{message}}</h3>
{{else}}
<h3 id="x-条件不满足-展示默认消息">(2x、条件不满足，展示默认消息</h3>
{{/if}}Traverse the collection:
{{each list as item index}}
<h3 id="the-nbsp-index-nbsp-of-nbsp-message-nbsp-is-nbsp-nbsp-index-nbsp-nbsp-item">the index of message is : {{index+1}} -> {{item}}</h3>
{{/each}}Auxiliary function: can be used to connect the backend The requested data is mapped, such as 1->normal, 0->error. When using it, you only need to pass "|func" after the expression, such as {{message | filterhandler}}, where filterhandler is a custom auxiliary function.
First define an auxiliary function. What is defined here is a simple date format conversion function.
template.helper("date2str",function(date){
var today = new Date(date);
var year = today.getFullYear();
var month = today.getMonth()+1;
if(month<10)month = "0"+month;
var day = today.getDate();
if(day<10)day = "0"+day;
return year+"-"+month+"-"+day;
});Use auxiliary functions
<p id="node4"></p>
<script id="tpl4" type="text/template">
<h1 id="template-helper-nbsp-func-nbsp-example">4、template.helper func example</h1>
<h3 id="today-nbsp-is-nbsp-datenow-nbsp-nbsp-date-str">today is {{datenow | date2str}}</h3>
</script>
//js代码中调用
var data4 = {datenow:new Date()};
$("node4").innerHTML = template("tpl4",data4);Pre-compilation: Different from using templates, pre-compilation requires a string type document fragment, and then passes the data to Precompiled templates are rendered.
var tpl5 = "<h1 id="compile-nbsp-example">5、compile example</h1><h3 id="this-nbsp-is-nbsp-a-nbsp-string-nbsp-the-nbsp-type-nbsp-is-nbsp-not-nbsp-type">this is a string the type is not {{type}}</h3>";
$("node5").innerHTML = template.compile(tpl5)({type:"text/template"});Reference sub-template:
<p id="node6"></p>
<script id="tpl6" type="text/template">
<h1 id="include-nbsp-child-nbsp-template-nbsp-example">6、include child template example</h1>
<p class="parenttemplate">
<h3 id="parent-nbsp-template">parent template</h3>
{{include 'tpl6-child'}}
</p>
</script>
<script id="tpl6-child" type="text/template">
<p class="childtemplate">
<h3 id="child-nbsp-template">child template</h3>
</p>
</script>2. Download the template.js library and introduce it into the html file.
3. Here is a comprehensive example to practice some of the syntax introduced earlier:
<!doctype html>
<html>
<head>
<meta charset="UTF-8"/>
<title>artTemplate example</title>
<style type="text/css">
*{margin:0;}
h1,h2,h3{margin:3px;}
h2,h3{text-indent:20px;}
.parenttemplate{background:#ccc;width:600px;height:60px;}
.childtemplate{background:lightblue;}
</style>
<script type="text/javascript" src="template.js"></script>
<script>
function $(id){return document.getElementById(id);}
window.onload = function(){
//data mapping
var data1 = {message:"hello,artTemplate is a javasript framework."};
$("node1").innerHTML = template("tpl1",data1);
//if condition
var data2 = {isShow:true,message:"hello,template"};
$("node2").innerHTML = template("tpl2",data2);
data2.isShow = false;
$("node2x").innerHTML = template("tpl2",data2);
//list foreach
var data3 = {list:["Javascript","JQuery","artTemplate"]};
$("node3").innerHTML = template("tpl3",data3);
//helper function
template.helper("date2str",function(date){
var today = new Date(date);
var year = today.getFullYear();
var month = today.getMonth()+1;
if(month<10)month = "0"+month;
var day = today.getDate();
if(day<10)day = "0"+day;
return year+"-"+month+"-"+day;
});
var data4 = {datenow:new Date()};
$("node4").innerHTML = template("tpl4",data4);
//compile example
var tpl5 = "<h1 id="compile-nbsp-example">5、compile example</h1><h3>this is a string the type is not {{type}}
</h3>";
$("node5").innerHTML = template.compile(tpl5)({type:"text/template"});
$("node6").innerHTML = template("tpl6",{});
//escape html
$("node7").innerHTML = template("tpl7",{message:"<span>escape html tag</span>"});
}
</script>
</head>
<body>
<p id="node1"></p>

{{/if}}
</script>
<p id="node3"></p>
<script id="tpl3" type="text/template">
<h1 id="list-nbsp-example">3、list example</h1>
{{each list as item index}}

{{/each}}

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
