使用主干调用下划线模板内的函数 [英] Call a function inside an underscore template using backbone

问题描述

我尝试做的一件事会真正简化我现在的生活.

我该怎么做:

这是我在应用文件中的视图

 window.ArtView = Backbone.View.extend({模板:_.template($('#art').html()),渲染:函数(事件名称){无功输出=blablbla"；$(this.el).html(this.template({"output":output}));返回这个；}});...//我想调用的函数函数调用函数(){console.log('它有效！');}

index.html 中的模板

如何在我的模板或类似的东西中调用 callFunction() ?

有什么想法吗?

谢谢！

解决方案

我相信只要模板的对象有函数，你就可以在模板内调用函数.

render:function (eventName) {无功输出=blablbla"；var data = _.extend({"output":output}, callFunction);$(this.el).html(this.template(data));返回这个；}

然后在您的模板中:

<%= callFunction() %>

Just a thing I try to do that would really simplify my life right now.

How can I do that :

This is my view in app file

    window.ArtView = Backbone.View.extend({
        template:_.template($('#art').html()),
        render:function (eventName) {
            var output="blablbla";
            $(this.el).html(this.template({"output":output}));
            return this;
        }
    });
    ...
    // function that I would like to call
    function callFunction(){
        console.log('it works!');
    }

Template in index.html

<script type="text/tempate" id="art">
        <div data-role="header" class="header" data-position="fixed">
            <a href="#" data-icon="back" class="back ui-btn-left">Back</a>
        </div>
        <div data-role="content" class="content">
            callFunction();
            <% console.log(output) %>
        </div>
</script>

How can I call callFunction() inside my template or something alike ?

Any idea ?

Thanks !

解决方案

I believe you can call functions within the template as long as the object for the template has the function.

render:function (eventName) {
    var output="blablbla";
    var data = _.extend({"output":output}, callFunction);
    $(this.el).html(this.template(data));
    return this;
}

then in your template:

<%= callFunction() %>
