js模板引擎-art-template常用总结

art-template

javascript 模板引擎,官网:https://github.com/aui/art-template

分为原生语法和简洁语法,本文主要是讲简洁语法

  • 基础数据渲染
  • 输出HTML
  • 流程控制
  • 遍历
  • 调用自定义函数方法
  • 子模板引入

基础数据渲染

一、引入art-template.js文件

<script src="template-debug.js"></script>

二、编写HTML模板

<script id="test" type="text/html">
    <h1>{{title}}</h1>
</script>

三、向模板插入数据,并输出到页面

var data = {
    title:"hello world"
};
var html = template("test",data);
document.getElementById('content').innerHTML = html;

输出HTML

<script id="test" type="text/html">
    <h1>{{title}}</h1>
</script>

//注意:{{title}}这是对内容编码输出,应该写成{{#title}}这是对内容不编码输出

<script id="test" type="text/html">
    <h1>{{#title}}</h1>
</script>

var data = {
    title:"<p>hello world</p>"
};
var html = template("test",data);
document.getElementById('content').innerHTML = html;

流程控制语句(if else)

{{if value}}
...
{{else if value}}
...
{{else}}
...
{{/if}}
art-template里面的流程控制就相对其他模板来说强大很多了,直接看例子吧

<script id="test" type="text/html">
    <div>
        {{if bok==22}}
        <h1>线上</h1>
        {{else if bok==33}}
        <h2>隐藏</h2>
        {{else}}
        <h3>走这里</h3>
        {{/if}}
    </div>
</script>
<script>
    var data = {
        "bok":22
    };
    var html = template('test',data);
    document.getElementById("app").innerHTML = html;
</script>

嵌套的写法

<script id="test" type="text/html">
    <div>
        {{if bok}}
            {{if list.length>=0}}
                {{each list}}
                    <p>{{$index}}:{{$value}}</p>
                {{/each}}
            {{else}}
                <p>没有数据</p>
            {{/if}}
        {{/if}}
    </div>
</script>
<script>
    var data = {
        "bok":true,
        list:["a","b","c"]
    };
    var html = template('test',data);
    document.getElementById("app").innerHTML = html;
</script>

循环遍历语句

{{each name}}
索引:{{$index}}
值:{{$value}}
{{/each}}

<script id="test" type="text/html">
<div>
    <ul>
        {{if c==100}}
            <ul>
                {{each person}}
                    <li>
                        编号:{{$index+1}}--姓名:{{$value.name}}--年龄:{{$value.age}}
                    </li>
                {{/each}}
            </ul>
        {{/if}}
    </ul>
</div>
</script>

<script>
    var data = {
        c:100,
        person:[
            {name:"jack",age:18},
            {name:"tom",age:19},
            {name:"jerry",age:20},
            {name:"kid",age:21},
            {name:"jade",age:22}
        ]
    };
    var html = template("test",data);
    document.getElementById("content").innerHTML = html;
</script>

调用自定义方法

通过template.helper(name,fnCallBack)注册方法
可以直接在{{}}中调用

<script id="test" type="text/html">
<div>
    {{if c==100}}
        <ul>
            {{each person}}
                <li>姓名:{{$value.name}}--性别:{{show($value.sex)}}</li>
            {{/each}}
        </ul>

    {{/if}}
</div>
</script>
<script>
    var data = {
        c:100,
        person:[
            {name:"jack",age:18,sex:1},
            {name:"tom",age:19,sex:0},
            {name:"jerry",age:20,sex:0},
            {name:"kid",age:21,sex:1},
            {name:"jade",age:22,sex:0}
        ]
    };
    //自定义函数
    template.helper("show",function(sex){
        console.log(sex);//同样可以打印日志到控制台
        if(sex==0){
            return "男"
        }else if(sex==1){
            return "女"
        }
    });
    var html = template("test",data);
    document.getElementById("app").innerHTML = html;
</script>

调用子模板

{{include 'main'}} 引入子模板,数据默认为共享
{{include 'main' a}} a为制定数据,但是同样必须是父级数据,可以看看下面的例子,如果不注入的a的话,引入的子模板是接受不到数据的

<body>
<div id="app"></div>
<script src="template-debug.js"></script>
<script id="main" type="text/html">
    <ul>
       {{each list}}
            <li>{{$value}}</li>
        {{/each}}
    </ul>
</script>
<script id="test" type="text/html">
    <div>
        <ul>
            {{each person}}
                <li>{{$value.name}}</li>
            {{/each}}
        </ul>
        {{include 'main' a}}
    </div>
</script>
<script>
    var data = {
        person:[
            {name:"jack",age:18},
            {name:"tom",age:19},
            {name:"jerry",age:20},
            {name:"kid",age:21},
            {name:"jade",age:22}
        ],
        a:{
            list:['文艺', '博客', '摄影', '电影', '民谣', '旅行', '吉他']
        }
    };
    var html = template("test",data);
    document.getElementById("app").innerHTML=html;
</script>
</body>
