我正在尝试使用http://ejohn.org/blog/javascript-micro-templating
构建模板构建器我的html有这个脚本标记
<script type="text/html" id="item_tmpl">
<div>
<div class="grid_1 alpha right">
</div>
<div class="grid_6 omega contents">
<p><b><a href="/<%=AdTitle%>"><%=AdTitle%></a>:</b> <%=AdTitle%></p>
</div>
</div>
</script>
<script src="${URLUtils.staticURL('/js/shoptheAd.js')}"type="text/javascript"></script>
The Script contains the following code
(function(app){
if (app) {
var cache = {};
this.tmpl = function tmpl(str, data){
// Figure out if we're getting a template, or if we need to
// load the template - and be sure to cache the result.
var fn = !/\W/.test(str) ?
cache[str] = cache[str] ||
tmpl(document.getElementById(str).innerHTML) :
// Generate a reusable function that will serve as a template
// generator (and which will be cached).
new Function("obj",
"var p=[],print=function(){p.push.apply(p,arguments);};" +
// Introduce the data as local variables using with(){}
"with(obj){p.push('" +
// Convert the template into pure JavaScript
str
.replace(/[\r\t\n]/g, " ")
.split("<%").join("\t")
.replace(/((^|%>)[^\t]*)'/g, "$1\r")
.replace(/\t=(.*?)%>/g, "',$1,'")
.split("\t").join("');")
.split("%>").join("p.push('")
.split("\r").join("\\'")
+ "');}return p.join('');");
// Provide some basic currying to the user
return data ? fn( data ) : fn;
};
var sitecoresuggestions = {
"suggestions": [
{
"AdTitle": "CheckAd",
"AdDescription": "",
"AdImageUrl": "http://demo-kiehls.loreal.photoninfotech.com/~/media/Advertisement Images/emma-watson-3.ashx",
"Count": 2,
"Hit": 0
},
{
"AdTitle": "CheckAd",
"AdDescription": "",
"AdImageUrl": "http://demo-kiehls.loreal.photoninfotech.com/~/media/Advertisement Images/kate2.ashx",
"Count": 2,
"Hit": 0
}
]
} ;
var show_user = tmpl("item_tmpl"), html = "";
for ( var i = 0; i < sitecoresuggestions.suggestions.length; i++ ) {
html += show_user( sitecoresuggestions.suggestions[i] );
}
console.log(html);
} else {
// namespace has not been defined yet
alert("app namespace is not loaded yet!");
}
})(app);
When the show_user = tmpl("item_tmpl") is executed
i get the error TypeError: document.getElementById(...) is null
关于调试我已经发现由于某种原因
<script type="text/html" id="item_tmpl">
<div>
<div class="grid_1 alpha right">
</div>
<div class="grid_6 omega contents">
<p><b><a href="/<%=AdTitle%>"><%=AdTitle%></a>:</b> <%=AdTitle%></p>
</div>
</div>
</script>
没有在浏览器中加载任何想法为什么它没有被加载,即使它包含在head标签内或任何其他指针中的错误原因

根据帖子:
快速提示:浏览器会忽略在页面中嵌入具有未知内容类型的脚本(例如,这里的情况 - >浏览器不知道如何执行text / html脚本) - 以及&gt;搜索引擎和屏幕阅读器。这是一个完美的隐形设备,可以将模板隐藏到&gt;您的页面中。我喜欢将这种技术应用于快速和肮脏的情况,我只需要在页面上使用一些&gt;模板,并且想要一些轻快的东西。
因此页面实际上并不呈现HTML,我认为您只能在页面中引用它,以便您可以提取并应用于其他对象或项目。正如博主所说,你会像以下一样使用它:
var results = document.getElementById("results");
results.innerHTML = tmpl("item_tmpl", dataObject);
