jQuery时间轴插件使用详解
这个时间轴是工作上用到的，自己写了一个， qq空间有时间轴的控件， 百度文库也有时间轴的控件；
百度的时间轴大概是这样的：
用户点击对应的锚链接， 那个三角会滚动， 然后左侧的界面也会滚动；
实际的效果如下图，用户点击左侧的按钮或者右侧的input，滚动条都会主动滚动， 这里有个小技巧就是用after和before伪类生成三角形， 用户点击按钮的滚动效果直接用jq的animate方法：
<!--
//设置内容;
window.onWebMessage( \'{\"type\":\"setItems\",\"data\":{\"items\":[{\"name\":1111},{\"name\":2222}]}}\' ) ;
//设置内容, 对应的item对象如果active为true为激活态;
window.onWebMessage( \'{\"type\":\"setItems\",\"data\":{\"items\":[{\"name\":1000},{\"name\":1111},{\"name\":2222},{\"name\":3333,\"active\":true}]}}\' ) ;
//设置某个第n个位置的item;
window.onWebMessage(\'{\"type\":\"setItem\",\"data\":[2,{ \"name\" : \"add-item\"}]}\');
//激活第三个锚链接为选中态;
window.onWebMessage( \'{\"type\":\"active\",\"data\":2}\' )
//获取目前的数据:
window.onWebMessage( \'{\"type\":\"getItem\"}\' );

模板用了underscore，tempate方法挂到了$下， 作为$的工具方法（依赖于jQuery），模板的js代码直接放这里方便一些小项目直接用：
//模板引擎的代码
(function () {
//underscore抄的模板引擎;
var escaper = /\\\\|\'|\\r|\\n|\\t|\\u2028|\\u2029/g;
var escapes = {
\"\'\": \"\'\",
\'\\\\\': \'\\\\\',
\'\\r\': \'r\',
\'\\n\': \'n\',
\'\\t\': \'t\',
\'\\u2028\': \'u2028\',
\'\\u2029\': \'u2029\'
};
$.templateSettings = {
evaluate : /<%([\\s\\S]+?)%>/g,
interpolate : /<%=([\\s\\S]+?)%>/g,
escape : /<%-([\\s\\S]+?)%>/g
}
$.template = function(text, data, settings) {
var render;
settings = $.extend({}, settings, $.templateSettings);
// Combine delimiters into one regular expression via alternation.
var matcher = new RegExp([
(settings.escape || noMatch).source,
(settings.interpolate || noMatch).source,
(settings.evaluate || noMatch).source
].join(\'|\') + \'|$\', \'g\');
// Compile the template source, escaping string literals appropriately.
var index = 0;
var source = \"__p+=\'\";
text.replace(matcher, function(match, escape, interpolate, evaluate, offset) {
source += text.slice(index, offset)
.replace(escaper, function(match) { return \'\\\\\' + escapes[match]; });
if (escape) {
source += \"\'+\\n((__t=(\" + escape + \"))==null?\'\':_.escape(__t))+\\n\'\";
}
if (interpolate) {
source += \"\'+\\n((__t=(\" + interpolate + \"))==null?\'\':__t)+\\n\'\";
}
if (evaluate) {
source += \"\';\\n\" + evaluate + \"\\n__p+=\'\";
}
index = offset + match.length;
return match;
});
source += \"\';\\n\";
// If a variable is not specified, place data values in local scope.
if (!settings.variable) source = \'with(obj||{}){\\n\' + source + \'}\\n\';
source = \"var __t,__p=\'\',__j=Array.prototype.join,\" +
\"print=function(){__p+=__j.call(arguments,\'\');};\\n\" +
source + \"return __p;\\n\";
try {
render = new Function(settings.variable || \'obj\', \'_\', source);
} catch (e) {
e.source = source;
throw e;
}
if (data) return render(data, _);
var template = function(data) {
return render.call(this, data);
};
// Provide the compiled function source as a convenience for precompilation.
template.source = \'function(\' + (settings.variable || \'obj\') + \'){\\n\' + source + \'}\';
return template;
};
})();
模板的使用的DEMO如下, 也可以参考官方的文档：http://underscorejs.org/#template：

var render;
settings = $.extend({}, settings, $.templateSettings);
// Combine delimiters into one regular expression via alternation.
var matcher = new RegExp([

// Compile the template source, escaping string literals appropriately.
var index = 0;
var source = \"__p+=\'\";
text.replace(matcher, function(match, escape, interpolate, evaluate, offset) {
source += text.slice(index, offset)
.replace(escaper, function(match) { return \'\\\\\' + escapes[match]; });

// If a variable is not specified, place data values in local scope.
if (!settings.variable) source = \'with(obj||{}){\\n\' + source + \'}\\n\';

}
if (data) return render(data, _);
var template = function(data) {
return render.call(this, data);
};
// Provide the compiled function source as a convenience for precompilation.
template.source = \'function(\' + (settings.variable || \'obj\') + \'){\\n\' + source + \'}\';
return template;
};
})();
</script>
<script>
//会输出 <div>haahah</div>;
console.log( $.template(\'<div><%=data%></div>\')( {data:\"haahah\"} ) );

修改了时间轴的样式， 又为这个插件添加了拖拽的方法，代码一下变得好乱， 顺便普及一下拖拽的事件， ondrop， ondragover，ondrag， 如果要让元素可以拖拽, 就要为要拖拽的元素添加draggable=\"true\", 元素可以拖拽以后 ， 要为可以拖放到的的DIV或者其他块元素，绑定一个dragover方法， 这个方法就做一件事， ev.preventDefault()， 看代码撒：
运行下面代码
<!DOCTYPE HTML>
<html>
<head>
<meta charset=\"utf-8\"/>
<style type=\"text/css\">
#div1 {width:488px;height:70px;padding:10px;border:1px solid #aaaaaa;}
</style>
<script type=\"text/javascript\">
//当元素dragover时候一定要阻止默认事件， 否则把当前拖拽的元素就无法drop;
function dragover(ev)
{
console.log(ev);
ev.preventDefault();
}
//对于拖拽事件最重要的一个事件属性就是dataTransfer;
function drag(ev)
{
console.log(ev);
ev.dataTransfer.setData(\"Text\",ev.target.id);
}
function drop(ev)
{
console.log(ev);
var data=ev.dataTransfer.getData(\"Text\");
ev.target.appendChild(document.getElementById(data));
}
</script>
</head>
<body>
<p>请把图片拖放到矩形中：</p>
<div id=\"div1\" ondrop=\"drop(event)\" ondragover=\"dragover(event)\"></div>
<br />
<img id=\"drag1\" src=\"http://images0.cnblogs.com/news/24442/201507/081152502219706.gif\" draggable=\"true\" ondragstart=\"drag(event)\" />
</body>
</html>
另外一个DEMO：
运行下面代码
<!DOCTYPE HTML>
<html>
<head>
<meta charset=\"utf-8\"/>
<style type=\"text/css\">
</style>
</head>
<body>
<p>What fruits do you like?</p>
<ol ondragstart=\"dragStartHandler(event)\">
<li draggable=\"true\" data-value=\"fruit-apple\">Apples</li>
<li draggable=\"true\" data-value=\"fruit-orange\">Oranges</li>
<li draggable=\"true\" data-value=\"fruit-pear\">Pears</li>
</ol>
<script>
var internalDNDType = \'text/x-example\'; // set this to something specific to your site
function dragStartHandler(event) {
if (event.target instanceof HTMLLIElement) {
// use the element\'s data-value=\"\" attribute as the value to be moving:
event.dataTransfer.setData(internalDNDType, event.target.dataset.value);
event.dataTransfer.effectAllowed = \'move\'; // only allow moves
} else {
event.preventDefault(); // don\'t allow selection to be dragged
}
}
</script>
<p>Drop your favorite fruits below:</p>
<ol ondrop=\"dropHandler(event)\" ondragover=\"dragover(event)\">
<!-- don\'t forget to change the \"text/x-example\" type to something
specific to your site -->
<li>drop</li>
</ol>
<script>
var internalDNDType = \'text/x-example\'; // set this to something specific to your site
function dropHandler(event) {
var li = document.createElement(\'li\');
var data = event.dataTransfer.getData(internalDNDType);
if (data == \'fruit-apple\') {
li.textContent = \'Apples\';
} else if (data == \'fruit-orange\') {
li.textContent = \'Oranges\';
} else if (data == \'fruit-pear\') {
li.textContent = \'Pears\';
} else {
li.textContent = \'Unknown Fruit\';
}
event.target.appendChild(li);
};
function dragover(ev) {
ev.preventDefault();
};
</script>
</body>
</html>
HTML5的拖拽提供了 setDragImage ， effectAllowed ， setData.... 等很多便捷的方法给开发者, 通过FileReader读取File， 然后就可以用ajax与后台进行交互， 和前端DOM操作：
<!DOCTYPE HTML>
<html>
<head>
<meta charset=\"utf-8\"/>
<style type=\"text/css\">
</style>
</head>
<body>
<div id=\"div0\" ondragover=\"dragover(event)\" ondrop=\"drop(event)\">
drop拖放文件进来
</div>
<script>
function dragover(ev) {
ev.preventDefault();
};
function drop(ev) {
var reader = new FileReader();
reader.onload = function ( ev ) {
var oDiv = document.createElement(\"div\");
oDiv.innerHTML = ev.target.result;
document.body.appendChild( oDiv );
};
reader.readAsText( ev.dataTransfer.files[0] );
ev.preventDefault();
}
</script>
</body>
</html>
