我在Backbonejs上初级。我想调用简单的模板。但它给了我以下错误:
*Uncaught TypeError: Cannot read property 'replace' of undefined*
请参阅我为其创建的plnk: http://plnkr.co/edit/fTcL4m?p=info
您也可以在此处找到代码:
<!DOCTYPE html>
<html>
<head>
<title>Loading a template</title>
</head>
<body>
<h1>Loading a template</h1>
<div id="search_container"></div>
<script data-require="jquery@2.2.0" data-semver="2.2.0" src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<script data-require="underscore.js@1.8.3" data-semver="1.8.3" src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
<script data-require="backbone.js@1.1.2" data-semver="1.1.2" src="//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js"></script>
<script>
SearchView = Backbone.View.extend({
initialize: function(){
this.render();
},
render: function(){
var template = _.template($("#search_template").html(), {});
this.el.html(template);
}
});
var search_view = new SearchView({ el: $("#search_container") });
</script>
<script type="text/template" id="search_template">
<label>Search</label>
<input type="text" id="search_input" />
<input type="button" id="search_button" value="Search" />
</script>
</body>
</html>
答案 0 :(得分:4)
主要问题是脚本标记的顺序,
<script type="text/template" id="search_template">
<label>Search</label>
<input type="text" id="search_input" />
<input type="button" id="search_button" value="Search" />
</script>
脚本运行时不存在。你应该确保它,通过在包含代码的代码之前添加代码,或者将代码包装在$(function(){})
等中。
另一个问题是您应该使用this.$el.html(template);
代替this.el.html(template);
