TaffyDB - 将数据呈现为HTML [英] TaffyDB - rendering data to HTML
本文介绍了TaffyDB - 将数据呈现为HTML的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
假设你有一个简单的TaffyDB数据库:
Lets say you have a simple TaffyDB database:
var example = TAFFY([
{fruit:"apple", color:"green", taste:"sweet"},
{fruit:"banana", color:"yellow", taste:"more sweet"},
{fruit:"tomato", color:"red", taste:"like tomato"}
]);
如何将一个接一个的水果随机渲染为HTML:
我的解决方案为javascript初学者:
How would you render randomly one fruit after another to HTML: My solution as a javascript beginner:
var fruit = example().count();
var random = Math.floor(Math.random()*count);
var fruit = example().select("fruit")[random];
var color = example().select("color")[random];
var taste = example().select("taste")[random];
$(document).ready(function(){
$('#somediv').append("<p>" + fruit + "</p>");
$('#somediv').append("<p>" + color + "</p>");
$('#somediv').append("<p>" + taste + "</p>");
});
我认为这太复杂了。
会不会另一种解决方案是什么?
推荐答案
在TaffyDB 2.0中,你可以使用取代作为你讨论的部分内容。
In TaffyDB 2.0 you can use supplant for part of what you discussing.
我可能会编写如下代码:
I might author the code something like this:
var example = TAFFY([
{fruit:"apple", color:"green", taste:"sweet", order:0},
{fruit:"banana", color:"yellow", taste:"more sweet", order:0},
{fruit:"tomato", color:"red", taste:"like tomato", order:0}
]);
$('#somediv').html(
example().update(function () {
this.order = Math.floor(Math.random() * 100);
return this;
}).order("order").supplant("<p>{fruit}</p>")
);
