我正在尝试在下划线模板中使用一个函数,如下所示,但出现错误:
未捕获的 ReferenceError:未定义 getProperty
下面是我正在使用的代码
var CustomerDetailView = Backbone.View.extend({
tagName : "div",
template: "#customer-detail-view-template",
initialize: function() {
_.bindAll(this, 'render');
this.model.bind('change', this.render);
this.initializeTemplate();
},
initializeTemplate: function() {
this.template = _.template($(this.template).html());
},
render: function() {
var data = this.model.toJSON();
_.extend(data, viewHelper);
console.log(data);
var html = _.template($(this.template), data);
$(this.el).html(html);
return this;
}
})
和模板:
<script type="text/template" id="customer-detail-view-template">
<div style="height: 70px;">
<span class="displayText">
<p class="searchResultsAuxInfo">Full Name : <%= getProperty("full_name", null) %> </p>
<p class="searchResultsAuxInfo">Country Code : <%= getProperty("country_code", null) %></p>
<p class="searchResultsAuxInfo">street : <%= getProperty("street", null) %></p>
<p class="searchResultsAuxInfo">maiden_name : <%= getProperty("maiden_name", null) %></p>
</span>
<span class="displayTextRight">
<p class="searchResultsAuxInfo">marital_status_code : <%= getProperty("marital_status_code", null) %></p>
<p class="searchResultsAuxInfo">tax_id_number : <%= getProperty("tax_id_number", null) %></p>
<p class="searchResultsAuxInfo">primary_phone : <%= getProperty("primary_phone", null) %></p>
<p class="searchResultsAuxInfo">customer_number : <%= getProperty("customer_number", null) %></p>
</span>
</div>
</script>
视图助手对象如下所示:
var viewHelper = {
getProperty:function(propertyName, object) {
if(typeof(object) === "undefined"){
object = this["attributes"];
}
for (i in object) {
if (_.isObject(object[i])) {
var currentObj = object[i];
if(_.has(currentObj, propertyName)){
return currentObj[propertyName];
}
this.getProperty(propertyName, currentObj);
}
}
}
}
