使用方法
編譯模板并根據(jù)數(shù)據(jù)立即渲染出結(jié)果
juicer(tpl, data);
僅編譯模板暫不渲染,返回一個(gè)可重用的編譯后的函數(shù)
var compiled_tpl = juicer(tpl);
根據(jù)給定的數(shù)據(jù)對之前編譯好的模板進(jìn)行渲染
var complied_tpl = juicer(tpl); var html = complied_tpl.render(data);
注冊/注銷自定義函數(shù)(對象)
juicer.register(‘function_name', function);juicer.unregister(‘function_name');
默認(rèn)參數(shù)配置
{ cache: true [false]; script: true [false]; error handling: true [false]; detection: true [false]; }
修改默認(rèn)配置,逐條修改
juicer.set('cache', false);
修改默認(rèn)配置,批量修改
juicer.set({ 'script': false, 'cache': false })
Juicer 默認(rèn)會對編譯后的模板進(jìn)行緩存,從而避免同一模板多次數(shù)據(jù)渲染時(shí)候重復(fù)編譯所耗的時(shí)間, 如無特殊需要,強(qiáng)烈不建議關(guān)閉默認(rèn)參數(shù)中的 cache,這么做將會令 Juicer 緩存失效從而降低性能.
語法
* ${變量}
- 使用${}輸出變量,其中_ 為對數(shù)據(jù)源的引用(${_})。支持使用自定義函數(shù)。
${name}${name|function}${name|function, arg1, arg2}
var = links: [{href: 'http://juicer.name', alt: 'Juicer'}, {href: 'http://benben.cc', alt: 'Benben'}, {href: 'http://ued.taobao.com', alt: 'Taobao UED'} ]}; var tpl = [ '{@each links as item}', '${item|links_build} <br />', '{@/each}'].join(''); var links = function(data) { return '<a href="' + data.href + '" alt="' + data.alt + '" />';};juicer.register('links_build', links); //注冊自定義函數(shù)juicer(tpl, json);
* 轉(zhuǎn)義/避免轉(zhuǎn)義
- ${變量} 在輸出之前會對其內(nèi)容進(jìn)行轉(zhuǎn)義,如果你不想輸出結(jié)果被轉(zhuǎn)義,可以使用 $${變量} 來避免這種情況。
var json = { value: '<strong>juicer</strong>' }; var escape_tpl='${value}'; var unescape_tpl='$${value}'; juicer(escape_tpl, json); //輸出 '<strong>juicer</strong>' juicer(unescape_tpl, json); //輸出 '<strong>juicer</strong>'
*循環(huán)遍歷 {@each} ... {@/each}
- 遍歷數(shù)組,${index}當(dāng)前索引
{@each list as item, index} ${item.prop} ${index} //當(dāng)前索引 {@/each}
*判斷 {@if} ... {@else if} ... {@else} ... {@/if}
*注釋 {# 注釋內(nèi)容}
{# 這里是注釋內(nèi)容}
*輔助循環(huán) {@each i in range(m, n)}
{@each i in range(5, 10)} ${i}; //輸出 5;6;7;8;9; {@/each}
*子模板嵌套 {@include tpl, data}
- 子模板嵌套除了可以引入在數(shù)據(jù)中指定的子模板外,也可以通過指定字符串`#id`使用寫在`script`標(biāo)簽中的模板代碼.
- HTML代碼:
<script type="text/juicer" id="subTpl"> I'm sub content, ${name}</script>
- Javascript 代碼:
var tpl = 'Hi, {@include "#subTpl", subData}, End.';juicer(tpl, {subData: {name: 'juicer'}});//輸出 Hi, I'm sub content, juicer, End. //或者通過數(shù)據(jù)引入子模板,下述代碼也將會有相同的渲染結(jié)果: var tpl = 'Hi, {@include subTpl, subData}, End.'; juicer(tpl, { subTpl: "I'm sub content, ${name}", subData: { name: 'juicer' } });
一個(gè)完整的例子
HTML 代碼:
<script id="tpl" type="text/template"> <ul> {@each list as it,index} <li>${it.name} (index: ${index})</li> {@/each} {@each blah as it} <li> num: ${it.num} <br /> {@if it.num==3} {@each it.inner as it2} ${it2.time} <br /> {@/each} {@/if} </li> {@/each} </ul> </script>
Javascript 代碼:
var data = { list: [ {name:' guokai', show: true}, {name:' benben', show: false}, {name:' dierbaby', show: true} ], blah: [ {num: 1}, {num: 2}, {num: 3, inner:[ {'time': '15:00'}, {'time': '16:00'}, {'time': '17:00'}, {'time': '18:00'} ]}, {num: 4} ] }; var tpl = document.getElementById('tpl').innerHTML; var html = juicer(tpl, data);
