参考我在这里遇到的原始问题,在做了大量的谷歌搜索之后,我找到了一个可行的解决方案,那就是这个How to append multiple Google Maps areas to divs using Handlebars。
然而,我用下面的方式实现了我的
var EmployeeView = function(employee){
this.render = function(){
$('body').append(this.el);
// inside the new div, put the Handlebars template, with the data from the employee
this.el.html(EmployeeView.template(employee)).ready( function() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
});
return this;
};
this.initialize = function(){
this.el=$("</div>");
window.localStorage.removeItem('paramId');
console.log('removed');
window.localStorage.setItem('paramId',employee);
console.log('added ' + employee.id);
};
this.initialize();
}
EmployeeView.template = Handlebars.compile($("#employee-tpl").html());我不确定这是否是“引用”该解决方案的正确方式,但是现在,每当我运行页面时,都会抛出以下错误:Uncaught ReferenceError: context is not defined
有人有什么想法吗?另外,我的html如下所示
<body>
<script id="employee-tpl" type="text/x-handlebars-template">
<div class='details'>
<img class='employee-image' src='img/{{firstName}}_{{lastName}}.jpg' />
<ul>
<li><a href="#map/{{this.id}}">See on map</a></li>
<li>Share with friends</li>
<li><div id="map-canvas"/></li>
</ul>
<script src="lib/iscroll.js"></script>
<script src="lib/handlebars.js"></script>
<script src="lib/jquery-1.8.2.min.js"></script>
<script src="js/storage/cafe-memory-store.js"></script>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?APIKEY&sensor=true"></script>
<script src="js/MapView.js"></script>
<script src="js/EmployeeView.js"></script>
<script src="js/HomeView.js"></script>
<script src="js/main.js"></script>

在这一行中:
$("employee-tpl").append(HTMLtemplate(context))您正在传递一个undefined函数和一个undefined变量(context)。context应包含您在要替换的HandlebarJS模板中定义的id参数
<a href="#map/{{this.id}}">See on map</a>在本例中,HTMLTemplate是EmployeeView.template,它包含HandlebarJS编译后的模板:它是一个接收context变量(或者employee变量?)作为参数的函数。
如果我没记错,你的代码应该是:
var EmployeeView = function(employee){
this.render = function(){
$('body').append(this.el);
// inside the new div, put the Handlebars template, with the data from the employee
this.el.html(EmployeeView.template(employee))).ready( function() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
});
return this;
};
this.initialize = function(){
this.el=.$("</div>");
window.localStorage.removeItem('paramId');
console.log('removed');
window.localStorage.setItem('paramId',employee);
console.log('added ' + employee.id);
};
this.initialize();
}
EmployeeView.template = Handlebars.compile($("#employee-tpl").html());我认为您必须将employee传递给模板,因为我在模板中看到了first_name和last_name。
