ejs跟angularjs相比，实在是太难写了，附实例！

<% if (data.success) { %>
<span><%= data.success %></span>
<% } %>

<% if (data.err) { %>
<span><%= data.err %></span>
<% } %>

<span>{{ data.success }}</span>
<span>{{ data.err }}</span>

var arrs = [{name:a, age:10}, {name:b, age:20}];

<% arrs.forEach(function (v, k){ %>
<span><%= v.name %></span>
<span><%= v.age %></span>
<% }) %>

<div ng-repeat="arr in arrs">
<span>{{ arr.name }}</span>
<span>{{ arr.age }}</span>
</div>
