JSBlocks 更好的 MV-ISH 框架
JSBlocks 是一个更好的 MV-ISH 框架，从简单的用户界面到使用更快、服务器端呈现和易于学习的框架的复杂单页应用程序。
特点
提高HTML的级别
用HTML编写代码查询。不需要学习新语法
<input data-query="val(newTodo)">双向数据绑定
通过使用可观测数据，使模型和视图始终保持同步。
this.newTodo = blocks.observable();处理数据
使用内置实用程序库进行高级和更快的数据操作。
blocks([1, 2, 3]).map(/* code */).filter(/* code */).each()(/* code */);

3、跑起来
Peng@PENG-PC /F/home/qianduan/jsblocks-seed (master)$ npm start
> jsblocks-seed@0.0.1 start f:\home\qianduan\jsblocks-seed
> opener http://localhost:8000 && blocks static
这样跑也行
Peng@PENG-PC /F/home/qianduan/jsblocks-seed (master)$ npm run node
> jsblocks-seed@0.0.1 node f:\home\qianduan\jsblocks-seed
> opener http://localhost:8000 && node app.js
Hello World
一个简单的例子
<!DOCTYPE html><html>
<head>
<script src="http://jsblocks.com/jsblocks/blocks.js"></script>
<script>
blocks.query({
firstName: blocks.observable('John'),
lastName: blocks.observable('Doe')
});
</script>
</head>
<body>
First Name: <input data-query="val(firstName)">
Last Name: <input data-query="val(lastName)">
<h2>Hello {{firstName}} {{lastName}}!</h2>
</body>
</html>
使用动画
这个例子显示了实现 CSS3 动画是多么容易。
HTML
<!DOCTYPE html><html>
<head>
<link rel="stylesheet" href="style.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
<script src="http://jsblocks.com/jsblocks/blocks.js"></script>
<script src="script.js"></script>
</head>
<body>
<input data-query="val(filterVal)" placeholder="Search for a block name">
<div class="result-box" data-query="each(items.view)">
<div class="tile" data-query="css('top', Math.floor($index() / 4) * 91).css('left', ($index() % 4) * 91)">
<span class="fa fa-{{icon}}"></span>
<h4>{{title}}</h4>
</div>
</div>
</body>
</html>
JS
var items = [ { icon: 'cubes', title: 'blocks' },
{ icon: 'exchange', title: 'bindings' },
{ icon: 'line-chart', title: 'speed' },
{ icon: 'database', title: 'data' },
{ icon: 'wrench', title: 'debugging' },
{ icon: 'server', title: 'architecture' },
{ icon: 'cube', title: 'modular'},
{ icon: 'cogs', title: 'extensible' },
{ icon: 'crosshairs', title: 'consistent' },
{ icon: 'lightbulb-o', title: 'innovative' },
{ icon: 'terminal', title: 'clean' },
{ icon: 'plug', title: 'feature rich' }
];
var filterVal = blocks.observable();
blocks.query({
filter: filterVal,
items: blocks.observable(items).extend('filter', function (value) {
return !filterVal() || value.title.indexOf(filterVal().toLowerCase()) != -1;
})
});
CSS
/* CSS Transitions *//* The built-in classes shown below allow for easy CSS transitions */
.tile.b-hide-end {
opacity: 0;
}
.tile.b-show {
opacity: 0;
}
.tile.b-show-end {
opacity: 1;
}
/* Other styles */
input { font-size: 16px; padding: 12px 16px; margin-bottom: 40px;
width: 326px; background: #ddf4e8; border: 1px solid #54b07e;}
.result-box { position: relative; text-align: center; }
.tile { position: absolute; width: 86px; background-color: #3ebee3;
height: 86px; color: #fff; transition: 1s linear all; }
.tile .fa { margin-top: 20px; font-size: 24px; }
.tile h4 { font-size: 14px; margin: 15px 0; }
简单应用
此示例使用 jsblock 提供的 MVC 体系结构构建。这个强大的模块允许您构建复杂的应用程序。但是，如果不需要此功能，则可以始终删除它以减少文件大小。
HTML
<!DOCTYPE html><html>
<head>
<link rel="stylesheet" href="style.css">
<script src="http://jsblocks.com/jsblocks/blocks.js"></script>
<script src="script.js"></script>
</head>
<body>
<div id="products" data-query="view(Products)">
<input data-query="val(newProduct.name).keydown(keydown)" placeholder="Add new value and press enter">
<div data-query="each(products)">
<div class="result-wrap">
<span data-query="visible(!editing())" class="value-holder">
{{name}}
</span>
<span data-query="visible(editing)" class="value-holder">
<input data-query="val(name)">
</span>
<span class="buttons-holder">
<span data-query="click(toggleEdit)">
{{editing() ? 'Update' : 'Edit'}}
</span>
<span data-query="click(remove)" class="btn-delete">Delete</span>
</span>
</div>
</div>
</div>
</body>
</html>
JS
var App = blocks.Application();var Product = App.Model({
name: App.Property(),
editing: blocks.observable(false),
toggleEdit: function () {
this.editing(!this.editing());
},
remove: function () {
this.destroy(true);
}
});
var Products = App.Collection(Product);
App.View('Products', {
newProduct: Product(),
products: Products([{ name: 'HTML' }, { name: 'CSS' }, { name: 'JavaScript' }]),
keydown: function (e) {
if (e.which == 13) {
this.products.add(this.newProduct);
this.newProduct.reset();
}
}
});
CSS
#products > input { font-size: 16px;
padding: 12px 16px;
width: 326px;
background: #ddf4e8;
border: 1px solid #54b07e;
}
.result-wrap {
margin-top: 10px;
border: 1px solid #dcdcdc;
background: #fbfbfb;
width: 360px;
}
.result-wrap .buttons-holder {
display: table-cell;
}
.buttons-holder > span {
cursor: pointer;
margin-left: 10px;
color: #2d8dc4;
}
.buttons-holder .btn-delete {
color: #e65f5f;
}
.result-wrap .value-holder {
display: table-cell;
border-right: 1px solid #dcdcdc;
width: 220px;
padding: 10px;
}
