【问题描述】:
所以参考我在这里遇到的原始问题Google Maps Javascript V3 Uncaught TypeError: Cannot read property 'offsetWidth' of null,在进行了大量谷歌搜索之后,我找到了一个我认为可行的解决方案,即How to append multiple Google Maps areas to divs using Handlebars。
但是,我通过以下方式实现了我的
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());
不确定这是否是“引用”该解决方案的正确方式,但现在,每当我运行该页面时,都会引发以下错误 Uncaught ReferenceError: context is not defined
有人有什么想法吗?并补充一下,我的html如下
<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>
</body>
【问题讨论】:
-
表示变量
context未定义:是不是也定义了HTMLtemplate(context)函数?否则我猜应该是EmployeeView.template。 -
但是提到stackoverflow.com/questions/10006898/…,它似乎不像HTMLTemplate和
context是额外定义的吗?请纠正我:( -
我可以在页面的代码sn-p中看到它们的定义。
