Knockout.js 从knockoutjs绑定调用模板

在knocoutjs绑定中，我想生成一些HTML并将其添加到元素中。此HTML与我已有的模板相同。我试着做显而易见的事情，并从另一个绑定调用模板绑定，但我得到了一个错误，如下所示

我的电话

// doc is a parameter to the method
var $assessments = $('div');
var docfcn = function() { return doc; }
var defaultAllBindingContexts = function() { return {}; }
ko.bindingHandlers.template.update($assessments, function() {return {name: 'assessmentControls', data: docfcn};}, defaultAllBindingContexts, doc);

错误：

我需要做什么才能正确触发模板

谢谢

更新2012年3月9日太平洋标准时间1:52:

我实施了@madcapnmckay建议的解决方案，如下所示：

    ko.renderTemplate('assessmentControls', doc, {}, $assessments, "replaceNode");

现在，我从模板中得到一个错误（这就是进度！）：

所讨论的模板如下所示：

<script id="assessmentControls" type="text/html">
    <div class="block docicons">
        <button title="Save document" 
            style="margin-top: 10px" 
            data-bind="assessment: 'REL', css: {selected: isRelevant}, button:{text: false, primary: 'assessment REL'}, filters: $parent.filters"></button> 
        <button title="Skip in future results" 
            data-bind="assessment: 'NOT_REL', css: {selected: isNotRelevant}, button:{text: false, primary: 'assessment NOT_REL'}, filters: $parent.filters"></button>
    </div>
</script>

因此，现在的问题是如何指定父级，以使模板的行为符合预期

添加了一个示例来说明上述错误。

要从绑定中呈现模板，可以使用

ko.renderTemplate

方法

ko.renderTemplate(template, dataOrBindingContext, options, 
    targetNodeOrNodeArray, renderMode)

e、 g

希望这有帮助

正如约翰·厄尔斯在评论中所说的那样。可以将绑定数据或bindingContext传递到方法中。模板将绑定到您传入的任何内容。如果希望访问$parent等，则由您创建该上下文。

谢谢，这很有帮助。我现在从我的模板中得到一个错误，如更新的问题中所示。你可以添加一个JSFIDLE来演示错误，我们可以看看它是否可以工作。我添加了一个示例JSFIDLE。你需要创建一个子上下文来提供$parent:@Kato-这是可选的，除非你想指定要使用的templateEngine，否则你不需要它。我复制并粘贴了一些KOV1代码。谢谢，这很有帮助。我现在从我的模板中得到一个错误，如更新的问题中所示。你可以添加一个JSFIDLE来演示错误，我们可以看看它是否可以工作。我添加了一个示例JSFIDLE。你需要创建一个子上下文来提供$parent:@Kato-这是可选的，除非你想指定要使用的templateEngine，否则你不需要它。我从一些KO V1代码中复制并粘贴了它。
