Question

我尝试使用gridster.add_widget方法将预呈现的模板传递到DOM中。

我一定不明白如何使用UI.renderWithData，因为每次调用UI命令时，我都会在最底部收到错误消息。

我对文档的理解是，这些命令将返回传入模板的完整格式的HTML。我已经通过为每个项目创建一个红色框来验证gridster是否正常工作。被召唤。

任何帮助都会非常感激。谢谢！

Template.projects.rendered = function(){

    gridster = $(".gridster div").gridster({
        widget_margins: [10, 10],
        widget_base_dimensions: [140, 140]
    }).data('gridster');

   var projectz = Projects.find({}, {sort: { time: -1}});
   $.each(projectz, function(index, widget){
       if (widget != undefined) {
           console.log(widget);

           // This works and adds a red box for each project in the database
           gridster.add_widget('<div style="background-color: red;">');

           // This does NOT work, I assume it is an issue with my use of UI.renderWithData
        // gridster.add_widget(UI.insert(UI.renderWithData(Template.projects, widget)), 1, 1);
       }
   });
};


//
// Error I get trying to gridster.add_widget() or console.log()
// with (UI.insert(UI.renderWithData(Template.projects, widget)));
//

UI.insert期望将DOM节点作为第二个参数，请参阅documentation。你在没有任何额外参数的情况下调用它。

您是否有理由不将所有Project元素渲染到模板中的页面？
