本文主要是介绍doT.js 模板引擎,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
插件描述:doT模板方便快捷的组织页面DOM
doT.js特点是快,小,无依赖其他插件。压缩版仅有4K大小,最近使用dot的时候整理出这个dot.js教程api文档,是对dot.js的介绍和实例,希望能帮助到一部分需要的人。
doT.js详细使用介绍
使用方法:
1 2 3 4 5 6 7 | {{= }} for interpolation {{ }} for evaluation {{~ }} for array iteration {{? }} for conditionals {{! }} for interpolation with encoding {{# }} for compile-time evaluation/includes and partials {{## #}} for compile-time defines |
调用方式:
1 2 | var tmpText = doT.template(模板); tmpText(数据源); |
例子一:
1、for interpolation 赋值
格式:
数据源:
1 | {"name":"Jake","age":31} |
区域:
1 | < div id = "interpolation" ></ div > |
模板:
1 2 3 4 | <script id= "interpolationtmpl" type= "text/x-dot-template" > <div>Hi {{=it.name}}!</div> <div>{{=it.age || '' }}</div> </script> |
调用方式:
1 2 3 | var dataInter = { "name" : "Jake" , "age" :31}; var interText = doT.template($( "#interpolationtmpl" ).text()); $( "#interpolation" ).html(interText(dataInter)); |
例子二:
2、for evaluation for in 循环
格式:
1 2 3 | {{ for var key in data { }} {{= key }} {{ } }} |
数据源:
1 | {"name":"Jake","age":31,"interests":["basketball","hockey","photography"],"contact":{"email":"jake@xyz.com","phone":"999999999"}} |
区域:
1 | < div id = "evaluation" ></ div > |
模板:
1 2 3 4 5 | <script id= "evaluationtmpl" type= "text/x-dot-template" > {{ for ( var prop in it) { }} <div>KEY:{{= prop }}---VALUE:{{= it[prop] }}</div> {{ } }} </script> |
调用方式:
1 2 3 | var dataEval = { "name" : "Jake" , "age" :31, "interests" :[ "basketball" , "hockey" , "photography" ], "contact" :{ "email" : "jake@xyz.com" , "phone" : "999999999" }}; var evalText = doT.template($( "#evaluationtmpl" ).text()); $( "#evaluation" ).html(evalText(dataEval)); |
例子三:
3、for array iteration 数组
格式:
1 2 3 | {{~data.array :value:index }} ... {{~}} |
数据源:
1 | { "array" :[ "banana" , "apple" , "orange" ]} |
区域:
1 | < div id = "arrays" ></ div > |
模板:
1 2 3 4 5 | <script id= "arraystmpl" type= "text/x-dot-template" > {{~it.array:value:index}} <div>{{= index+1 }}{{= value }}!</div> {{~}} </script> |
调用方式:
1 2 3 | var dataArr = { "array" :[ "banana" , "apple" , "orange" ]}; var arrText = doT.template($( "#arraystmpl" ).text()); $( "#arrays" ).html(arrText(dataArr)); |
例子四:
4、{{? }} for conditionals 条件
格式:
1 2 3 | {{? }} if {{?? }} else if {{??}} else |
数据源:
1 | {"name":"Jake","age":31} |
区域:
1 | < div id = "condition" ></ div > |
模板:
1 2 3 4 5 6 7 8 9 | <script id= "conditionstmpl" type= "text/x-dot-template" > {{? !it.name }} <div>Oh, I love your name, {{=it.name}}!</div> {{?? !it.age === 0}} <div>Guess nobody named you yet!</div> {{??}} You are {{=it.age}} and still dont have a name? {{?}} </script> |
调用方式:
1 2 3 | var dataEncode = { "uri" : "http://jq22.com/?keywords=Yoga" , "html" : "<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>" }; var EncodeText = doT.template($( "#encodetmpl" ).text()); $( "#encode" ).html(EncodeText(dataEncode)); |
例子五:
5、for interpolation with encoding
数据源:
1 | {"uri":"http://jq22.com/?keywords=Yoga"} |
格式:
区域:
1 | < div id = "encode" ></ div > |
模板:
1 2 3 | <script id= "encodetmpl" type= "text/x-dot-template" > Visit {{!it.uri}} {{!it.html}} </script> |
调用方式:
1 2 3 | var dataEncode = { "uri" : "http://jq22.com/?keywords=Yoga" , "html" : "<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>" }; var EncodeText = doT.template($( "#encodetmpl" ).text()); $( "#encode" ).html(EncodeText(dataEncode)); |
例子六:
6、{{# }} for compile-time evaluation/includes and partials
{{## #}} for compile-time defines
数据源:
1 | {"name":"Jake","age":31} |
区域:
模板:
1 2 3 4 5 6 7 | <script id= "parttmpl" type= "text/x-dot-template" > {{ ##def.snippet: <div>{{=it.name}}</div>{{ #def.joke}} #}} {{ #def.snippet}} {{=it.html}} </script> |
调用方式:
1 2 3 4 | var dataPart = { "name" : "Jake" , "age" :31, "html" : "<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>" }; var defPart = { "joke" : "<div>{{=it.name}} who?</div>" }; var partText = doT.template($( "#parttmpl" ).text(), undefined, defPart); $( "#part" ).html(partText(dataPart)); |
