jQuery时间轴插件使用详解
网络编程 2021-07-04 21:48www.168986.cn编程入门
本文给大家分享的是使用jQuery制作的模仿百度时间轴特效的代码,效果非常不错,有需要的小伙伴可以参考下。
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"}' ); --> <html> <head> <meta charset="utf-8" /> <script src="http://cdn.bootcss./jquery/2.1.4/jquery.js"></script> </head> <style> /*初始的reset样式*/ *{ margin:0; padding:0; } .time-line-wrap{ position: relative;

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 piled function source as a convenience for prepilation. 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::
<html> <head> <body> <script src="http://cdn.bootcss./jquery/2.1.4/jquery.js"></script> <script> //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 piled function source as a convenience for prepilation. 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"} ) ); </script> </body> </head> </html>
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:

<!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.blogs./news/24442/201507/081152502219706.gif" draggable="true" ondragstart="drag(event)" /> </body> </html> 另外一个DEMO: 运行狼蚁网站SEO优化代码 <!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 fet 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>
