默认的开始标签和结束标签分别是:
sTag: '<%',//开始标签,可以重写,我项目中使用的是<:
eTag: '%>',//结束标签,我项目中使用的是:>
快速上手
编写模板
使用一个type=”text/html”的script标签存放模板,或者放到字符串中:
<script type="text/html"> <ul> <%for(var i = 0; i < list.length; i++) {%> <li><%:=list[i].name%></li> <%}%> </ul> </script>
渲染模板
var tpl = document.getElementById('tpl').innerHTML; template(tpl, {list: [{name: "yan"},{name: "haijing"}]});
输出:
<ul> <li>yan</li> <li>haijing</li> </ul>
转义
<script type="text/html"> <table> <caption>for循环输出两次</caption> <%var test = '输出自定义变量';%> <%for (var i = 0; i < 2; i++) {%> <tr><td><%=html%>默认</td><td><%=html%></td></tr> <tr><td><%:h=html>html转义</td><td><%:h=html%></td></tr> <tr><td><%:=html>不转义</td><td><%:=html%></td></tr> <tr><td><%:u=url>URI转义</td><td><%:u=url%></td></tr> <tr><td>var</td><td><%:=test%></td></tr> <tr><td><%=test + 1>表达式</td><td><%=test + 1%></td></tr> <%if (true) {%> <tr><td>if</td><td>if 语句</td></tr> <%}%> <tr><td>分割线</td><td>------------------------------</td></tr> <%}%> </table> </script> <script src="https://www.jb51.net/template.js"></script> <script> var html = template(document.getElementById('tpl').innerHTML, { url: 'http://yanhaijing.com?name=颜海镜', html: '<div>template.js "</div>' }); console.log(html); document.getElementById('wp').innerHTML = html; </script>
<script> template.config({sTag: '<#', eTag: '#>'}); var tpl1 = '<div><#:=name#></div>'; console.log('<##>:', template(tpl1, {name: '更改tag<##>'})); template.config({sTag: '{{', eTag: '}}'}); var tpl1 = '<div>{{:=name}}</div>'; console.log('{{}}:', template(tpl1, {name: '更改tag{{}}'})); template.config({sTag: '<%', eTag: '#>'}); var tpl1 = '<div><%:=name#></div>'; console.log('<%#>:', template(tpl1, {name: '不一致也可以哦,更改tag<%#>'})); template.config({sTag: '<%', eTag: '%>', compress: true}); var tpl1 = '<div>空格会被压缩 空格 空格</div>'; console.log('compress:', template(tpl1, {})); template.config({sTag: '<%', eTag: '%>', escape: false}); var tpl1 = '<div>默认输出不进行转义<%=html%></div>'; console.log('escape:', template(tpl1, {html: '<div>html</div>'})); </script>
注册函数
<div></div> <script type="text/html"> <%=dateFormat(Date.now(), 'yyyy年 MM月 dd日 hh:mm:ss')%> </script> <script src="https://www.jb51.net/template.js"></script> <script> template.registerFunction('dateFormat', function (date, format) { date = new Date(date); var map = { "M": date.getMonth() + 1, //月份 "d": date.getDate(), //日 "h": date.getHours(), //小时 "m": date.getMinutes(), //分 "s": date.getSeconds(), //秒 "q": Math.floor((date.getMonth() + 3) / 3), //季度 "S": date.getMilliseconds() //毫秒 }; format = format.replace(/([yMdhmsqS])+/g, function(all, t){ var v = map[t]; if(v !== undefined){ if(all.length > 1){ v = '0' + v; v = v.substr(v.length-2); } return v; } else if(t === 'y'){ return (date.getFullYear() + '').substr(4 - all.length); } return all; }); return format; }); console.log(template.registerFunction()); console.log(template.registerFunction('dateFormat')); </script> <script> var html = template(document.getElementById('tpl').innerHTML, {}); console.log(html); document.getElementById('wp').innerHTML = html; template.unregisterFunction('dateFormat'); console.log(template.registerFunction('dateFormat')); </script> <div></div> <script type="text/html"> <%:up='yanhaijing'%> </script> <script src="https://www.jb51.net/template.js"></script> <script> template.registerModifier('up', function (str) { return str.toUpperCase(); }); console.log(template.registerModifier()); console.log(template.registerModifier('up')); </script> <script> var html = template(document.getElementById('tpl').innerHTML, {}); console.log(html); document.getElementById('wp').innerHTML = html; template.unregisterModifier('up'); console.log(template.registerModifier('up')); </script>
