代码示例:
<!DOCTYPE html> <html> <head> <title>Handlebars Expressions Example</title> </head> <body> <h1>Handlebars Expressions Example!</h1> <!--this is a list which will rendered by handlebars template. --> <div id="list"> </div> <script type="text/javascript" src=\'#\'" /jquery.js"></script> <script type="text/javascript" src=\'#\'" /handlebars-1.0.0.beta.6.js"></script> <script id="people-template" type="text/x-handlebars-template"> {{#people}} <div class="person"> <h2>{{first_name}} {{last_name}}</h2> <div class="phone">{{phone}}</div> <div class="email"><a href="mailto:{{email}}">{{email}}</a></div> <div class="since">User since {{member_since}}</div> </div> {{/people}} </script> <script type="text/javascript"> $(document).ready(function() { // compile our template var template = Handlebars.compile($("#people-template").html()); var data = { people: [ { first_name: "rui", last_name: "fengyun", phone: "1234567890", email: "alan@test.com", member_since: "Mar 25, 2011" }, { first_name: "Allison", last_name: "House", phone: "0987654321", email: "allison@test.com", member_since: "Jan 13, 2011" }, { first_name: "Nick", last_name: "Pettit", phone: "9836592272", email: "nick@test.com", member_since: "Apr 9, 2009" }, { first_name: "Jim", last_name: "Hoskins", phone: "7284927150", email: "jim@test.com", member_since: "May 21, 2010" }, { first_name: "Ryan", last_name: "Carson", phone: "8263729224", email: "ryan@test.com", member_since: "Nov 1, 2008" } ] }; $('#list').html(template(data)); }); </script> </body> </html>
进行遍历里面的数据,print出来
<script id="each-template" type="text/x-handlebars-template"> {{#each people}} ... output person's info here... {{/each}} </script>
有数据的话,进行数据渲染
<script id="each-template" type="text/x-handlebars-template"> {{#if people}} ... output person's info here... {{/if}} </script>
没有数据的话,就写没有数据
<script id="each-template" type="text/x-handlebars-template"> {{#unless people.length}} There aren't any people. {{/unless}} </script>
if else 关联的判断
<script id="each-template" type="text/x-handlebars-template"> {{#if people.length}} ... output person's info here... {{else}} There aren't any people. {{/if}} </script>
