icanhaz.js 模板的输出是 [object Array] 而不是渲染的模板
我正在使用 Zepto.js、ICanHaz.js 和 Backbone.js。我有几个正在尝试渲染的模板。渲染模板并将结果插入页面后,我看到的唯一输出是 [object Array] 或 [object HTMLTableElement]。
这是backbone.js Router
InspectionsRouter = Backbone.Router.extend({
routes: {
"signin": "signin",
"orders": "orders"
},
signin: function() {
var signinForm = new SignInForm();
$('div#content').html(signinForm.render());
},
orders: function() {
InspectionsApp.active_orders = new Orders();
InspectionsApp.active_orders.fetch({
success: function() {
var order_list = new OrderList({
collection: InspectionsApp.active_orders
});
$('div#content').html(order_list.render());
},
error: function() {
Dialog.error("Unable to Load Active Orders");
}
});
}
});
第一个模板是静态的,没有插入数据。这是代码
SignInForm = Backbone.View.extend({
render: function() {
this.el = ich.sign_in_form({});
return this.el;
}
});
另一个模板有点复杂。
var OrderList = Backbone.View.extend({
tagName: 'table',
id: 'order_list',
initialize: function() {
_.bindAll(this, 'render');
},
render: function() {
var active_orders = {};
active_orders.orders = this.collection;
$(this.el).html(ich.order_list(active_orders));
return this.el;
}
});
实际的模板并不是很复杂。第一个是简单的登录表单。接下来是一张桌子。
这是第一个模板。
<script id="sign_in_form" type="text/html">
<h2 class="page_title">Sign In</h2>
<form action="action/login.php" method="post" id="frm_login" name="frm_login">
<fieldset id="credentials">
<ol>
<li class="login">
<label for="email">E-mail Address</label>
<input type="email" name="email" id="email" tabindex="1" required>
</li>
<li class="login">
<label for="password">Password</label>
<input type="password" name="password" id="password" tabindex="2" required>
</li>
</ol>
</fieldset>
<button class="button" id="btn_sign_in" type="submit" tabindex="3"><img src="icons/door_in.png">Sign In</button>
</form>
</script>
这是第二个模板。
<script id="order_list" type="text/html">
<thead>
<tr>
<th>Name</th>
<th>E-mail</th>
<th>Status</th>
<th>Created</th>
<th>Assigned To</th>
</tr>
</thead>
<tbody id="order_list_body">
{{#orders}}
<tr>
<td>{{last_name}}, {{first_name}}</td>
<td>{{email}}</td>
<td>{{status}}</td>
<td>{{created_at}}</td>
<td>{{assigned_to}}</td>
</tr>
{{/orders}}
</tbody>
</script>
任何帮助将不胜感激。问题似乎出在 ICanHaz 或 Backbone 中。我尝试使用渲染方法提醒 this.el ,但仍然遇到同样的问题。
I am using Zepto.js, ICanHaz.js, and Backbone.js. I have a couple of templates that I am trying to render. After rendering the template and inserting the result into the page, the only output that I seeing is [object Array] or [object HTMLTableElement].
Here is the backbone.js Router
InspectionsRouter = Backbone.Router.extend({
routes: {
"signin": "signin",
"orders": "orders"
},
signin: function() {
var signinForm = new SignInForm();
$('div#content').html(signinForm.render());
},
orders: function() {
InspectionsApp.active_orders = new Orders();
InspectionsApp.active_orders.fetch({
success: function() {
var order_list = new OrderList({
collection: InspectionsApp.active_orders
});
$('div#content').html(order_list.render());
},
error: function() {
Dialog.error("Unable to Load Active Orders");
}
});
}
});
The first template is static and has no data inserted. Here is code
SignInForm = Backbone.View.extend({
render: function() {
this.el = ich.sign_in_form({});
return this.el;
}
});
The other template is somewhat more complicated.
var OrderList = Backbone.View.extend({
tagName: 'table',
id: 'order_list',
initialize: function() {
_.bindAll(this, 'render');
},
render: function() {
var active_orders = {};
active_orders.orders = this.collection;
$(this.el).html(ich.order_list(active_orders));
return this.el;
}
});
The actual templates aren't very complicated. The first is a simple sign in form. The next is a table.
Here is the first template.
<script id="sign_in_form" type="text/html">
<h2 class="page_title">Sign In</h2>
<form action="action/login.php" method="post" id="frm_login" name="frm_login">
<fieldset id="credentials">
<ol>
<li class="login">
<label for="email">E-mail Address</label>
<input type="email" name="email" id="email" tabindex="1" required>
</li>
<li class="login">
<label for="password">Password</label>
<input type="password" name="password" id="password" tabindex="2" required>
</li>
</ol>
</fieldset>
<button class="button" id="btn_sign_in" type="submit" tabindex="3"><img src="icons/door_in.png">Sign In</button>
</form>
</script>
Here is the second template.
<script id="order_list" type="text/html">
<thead>
<tr>
<th>Name</th>
<th>E-mail</th>
<th>Status</th>
<th>Created</th>
<th>Assigned To</th>
</tr>
</thead>
<tbody id="order_list_body">
{{#orders}}
<tr>
<td>{{last_name}}, {{first_name}}</td>
<td>{{email}}</td>
<td>{{status}}</td>
<td>{{created_at}}</td>
<td>{{assigned_to}}</td>
</tr>
{{/orders}}
</tbody>
</script>
Any help would be appreciated. The problem seems to be with ICanHaz or in Backbone. I have tried alerting this.el from with the render method and still get the same issue.

我想通了这个问题。 ICanHaz.js 默认返回 jQuery 或 Zepto 对象。 (我期待一个字符串。)您可以向 ich.template 函数添加第二个参数以触发原始字符串输出。返回 Zepto 对象不会有问题,只是在 Zepto 中 $.html() 不接受 Zepto 对象。选项是让 ICanHaz.js 输出原始字符串,或者使用接受 Zepto 对象的 Zepto 方法之一(追加、前置、之前、之后)。
要将数组渲染为字符串,只需使用:
ich.myRenderFunction(myObject, true);
I figured out the issue. ICanHaz.js by default returns a jQuery or Zepto object. (I was expecting a string.) You can add a second parameter to the ich.template function to trigger the raw string output. Returning the Zepto object wouldn't be a problem except that, in Zepto, $.html() doesn't accept a Zepto object. The options are to have ICanHaz.js output the raw string, or to use one of the Zepto methods that accept a Zepto object (append, prepend, before, after).
To render the array to a string, just use:
ich.myRenderFunction(myObject, true);
当模板未正确解析时,这种情况就会发生在我身上:通常是实际模板中的错误。验证模板数据没有问题并且已正确加载。
That happens to me when the template wasn't properly parsed: typically an error in the actual template. Verify there are no issues with the template data and that it is being properly loaded.
