很少发现网上有简洁好用的自定义前端控件的贴子,最近项目中需要,自己YY开始写前端控件,在此给大家分享
控件是基于jQuery.UI的Widget写的,写起来就方便很多,使用起来跟普通jQuery控件一样$(#id).control(option),看着眼熟吧,下面就开始了。
首先说下控件的依赖包,加载控件的时候必须先加载jQuery, jQuqery.UI, 另外jquery-ui.css
这个包也需要引用,此包主要应用了jQuery拖拽和放缩的样式,控件样式方面大家自由发挥,给了个自己写的默认样式包 (献丑了)。
控件本身支持颜色自定义,可根据日期自定义日历上某日的颜色,另外可悬浮,拖拽,自由变形算是卖点吧,哈哈
控件包加载是这样的:
<link href="../../Content/themes/base/jquery-ui.css" rel="stylesheet" /> <link href="../../Content/datePrinter.css" rel="stylesheet" /> <script src="/UploadFiles/2021-04-02/jquery-ui-1.8.20.min.js">控件中的核心部分就是打印选中月的日历,是参考网上的代码,偷懒嘛,欢迎认领
例如页面代码如下:
<input type="text" id="datepickerInput"/>
调用的写法:
var dpCon = $("#datepickerInput").datePrinter({ initDate: "2017-4-5", //初始化日期 language: "EN", //语言 resizable: true, //可自由变形 draggable: true, //可悬浮拖拽 showYearAndMonth: true, //是否显示年月下拉框 getColor: getColor, //自定义颜色接口 chooseDone: chooseDone //选中日历某日执行事件接口 }); //选中日期时让日历消失 当然此处可以执行比较复杂的业务,如服务器数据请求 function chooseDone(date) { dpCon.datePrinter("dpHide"); } //自定义日期颜色 function getColor(day){ if(day == 3 || day==7 || day==15) return "dpdisabled"; else if(day== 5 || day==18 || day==23) return "dpyellow"; else return "dpenable"; } //获取当前选中的日期 调用控件提供的API getSelectDate dpCon.datePrinter("getSelectDate");这样子就给上面的input text控件注册了一个日历控件,在点击input时,日历就会浮出,效果如下
你可能注意到右下角的小三角了,鼠标放上去之后可以随意变化日历的长宽,另外在日历上按住鼠标左键可以随意移动日期控件的位置,不挤占页面位置
下面这段是打印日历的代码,供参考:
//默认获取当前日期 var today = option.initDate " dateTD"; (day <= 0 || day > days_per_month[m]) "dpBlank") : (day = idx - dayOfWeek + 2); day == d "' + styleName + ' today">' + day + '</td>' : //高亮显示当天 tr += '<td class="' + styleName + '">' + day + '</td>'; } tr += '</tr>'; self._dpTable.append(tr); tr = ""; }以前都是写后台,玩前端的时间不长,有不对的地方欢迎指正
datePrinter.js的全部代码如下:
var _datePrinter_tmpl_CN = "<tr><th>一</th><th>二</th><th>三</th><th>四</th><th>五</th><th>六</th><th>日</th></tr>"; var _datePrinter_tmpl_EN = "<tr><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th><th>Sat</th><th>Sun</th></tr>"; Date.prototype.Format = function (fmt) { //author: meizz var o = { "M+": this.getMonth() + 1, //月份 "d+": this.getDate(), //日 "h+": this.getHours(), //小时 "m+": this.getMinutes(), //分 "s+": this.getSeconds(), //秒 "q+": Math.floor((this.getMonth() + 3) / 3), //季度 "S": this.getMilliseconds() //毫秒 }; if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length)); for (var k in o) if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) "00" + o[k]).substr(("" + o[k]).length))); return fmt; } $.widget("ui.datePrinter", { options: { initDate: null, language: null, // CN,EN resizable: false, draggable: false, width: "240px", dateFormat:'yyyy/MM/dd', getColor: null, //自定义颜色 showYearAndMonth: false, chooseDone: function (selectDate) { return selectDate }, //选中日期后执行的自定义事件 autoId:null //控件Id }, _dpTable: null, _dpRoot:null, _selectDate:null, //选中日期 _create: function () { var self = this, option = this.options, ele = this.element; $(ele).after("<div class='dpRoot'></div>"); self._dpRoot = $(ele).parent().find('div.dpRoot'); self._dpRoot.empty(); self._dpRoot.append("<div class='dpTitle' style='text-align:right;background-color:#e8edf4; width:" + option.width + "'><select class='selYear'></select><select class='selMonth'></select><a style='color:#000;text-decoration:none;font-size:18px;padding-left:10px; padding-right:10px;width:10px;' href='javascript:void(0);'>x</a></div>"); self._dpRoot.append("<table style='width:" + option.width + "' cellspacing='0'></table>"); option.autoId = self._newGuid(); }, _init: function () { var self = this, option = this.options, ele = this.element; if (option.initDate && typeof option.initDate == 'string') option.initDate = new Date(option.initDate.replace("-", "/")); //初始化日历 self._initDate(); //点击事件 self._dpTable.delegate("td", "click", function () { if (!$(this).hasClass("dpBlank")) { self._dpTable.find("td").removeClass("today"); $(this).addClass("today"); //控件设置值 $.proxy(self._setDate($(this).text()), self); if (option.chooseDone && typeof (option.chooseDone) == 'function') $.proxy(option.chooseDone(self._selectDate), self); } }); if (option.resizable) self._dpRoot.resizable({ minHeight: self._dpRoot.css("height").replace("px",''), minWidth:option.width.replace("px",''), resize: function (event, ui) { var titleHeight = self._dpRoot.find("div.dpTitle").css("height").replace("px", ""); //最小值时不再缩小 if (ui.size.width >= Number(option.width.replace("px",''))) { $(ui.element).find("table").css({ "width": ui.size.width, "height": ui.size.height - titleHeight, "text-align": "center" }); $(ui.element).find("div.dpTitle").css({ "width": ui.size.width }); } } }); if(option.draggable) self._dpRoot.draggable(); //关闭按钮事件 self._dpRoot.find("div.dpTitle > a").bind("click", function () { $.proxy(self.dpHide(), self); }); if (option.showYearAndMonth) { self._initSelYear(); self._initSelMonth(); } $(ele).focus(function () { self.dpShow(); }); $(ele).click(function () { self.dpShow(); }); //$(ele).blur(function (e) { // if ($(e.target).closest('div.dpRoot').length == 0) { // self.dpHide(); // } //}); }, _destroy: function () { var self = this, option = this.options, ele = this.element; self._dpRoot.empty(); this._prototype._destroy.call(self); }, _getColor: function (date) { var styleName = null; if (date == 3 || date == 5 || date == 12) styleName = "dpdisabled"; else if (date == 20 || date == 23 || date == 27) styleName = "dpyellow"; else styleName = "dpenable"; return styleName; }, _initSelYear: function () { var self = this, option = this.options, ele = this.element; //根据初始化设置时间计算 var today = option.initDate "selected='selected'" : ""; self._dpRoot.find("select.selYear").show().append("<option value='" + (y + i - 10) + "' " + varSel + ">" + (y + i - 10) + "</option"); } //年事件 self._dpRoot.find("select.selYear").bind("change", function () { option.initDate = new Date(option.initDate.setYear($(this).val())); self._initDate(); }); }, _initSelMonth: function () { var self = this, option = this.options, ele = this.element; //根据初始化设置时间计算 var today = option.initDate "selected='selected'" : ""; self._dpRoot.find("select.selMonth").show().append("<option value='" + (i + 1) + "' " + varSel + ">" + (i + 1) + "</option"); } //月事件 self._dpRoot.find("select.selMonth").bind("change", function () { var selMon = Number($(this).val()) - 1; option.initDate = new Date(option.initDate.setMonth(selMon)); self._initDate(); }); }, _initDate: function () { var self = this, option = this.options, ele = this.element; self._dpTable = self._dpRoot.find("table"); self._dpTable.empty(); if (option.language == "EN") { self._dpTable.wrapInner(_datePrinter_tmpl_EN); } //默认获取当前日期 var today = option.initDate " dateTD"; (day <= 0 || day > days_per_month[m]) "dpBlank") : (day = idx - dayOfWeek + 2); day == d "' + styleName + ' today">' + day + '</td>' : //高亮显示当天 tr += '<td class="' + styleName + '">' + day + '</td>'; } tr += '</tr>'; self._dpTable.append(tr); tr = ""; } }, _isLeap: function (year) { var self = this, option = this.options, ele = this.element; return year % 4 == 0 ""; for (var i = 1; i <= 32; i++) { var n = Math.floor(Math.random() * 16.0).toString(16); guid += n; if ((i == 8) || (i == 12) || (i == 16) || (i == 20)) { //guid += "-"; } } return guid; } });样式本人是业余的,勉强看看吧,由于datePrinter.js有依赖css的class名称,贴出来datePrinter.css文件代码如下
.dpBlank { background-color: white; cursor: not-allowed; } .dpRoot { width: 240px; position:absolute; display:none; } .today { border: 2px double #FF9900 !important; } .dpenable { background-color: #AABBFF; } .dpyellow { background-color: #FFC266; } .dpdisabled { background-color: #B0AEA4; } .dpRoot table { font-size: 13px; width: inherit; } .dpRoot table th { font-size: 12px; border: solid 2px #e8eef4; padding: 2px 3px; background-color: #e8eef4; border-collapse:initial; text-align: center; width: 22px; } .dpRoot table td { color: white; padding: 4px 5px; border: solid 2px #e8eef4; } .dpTitle { padding: 3px 0 0 0; } .dateTD { cursor: pointer; } .selYear { margin-right: 5%; display: none; font-size:14px; } .selMonth { margin-right: 5%; display: none; font-size:14px; }以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
