arcgis的timeslider是对dojo slider二次封装,
项目需要,所有Map用统一样式的slider,所以写了一个common的dojo class,统一调用生成slider,作为对timeslider再次封装,感觉挺好用。
这个slider不一定要在Map里使用,还可以在其他地方调用。只是要包含arcgis的js包,
先上JavaScript class的code:
-
- dojo.declare("mapSlider.MyTimeSlider",null,{
- map: null,
- startDate:null,
- endDate:null,
- divId:"myTimeSlider",
- timeUnit:"esriTimeUnitsHours",
- labelImg:"",
-
- labels:[],
- labelFooterDateFormat: "dd MMM yyyy HH:mm",
- labelTopDateFormat: "dd MMM yyyy HH:mm",
- timeExtent:null,
-
- timeSliderCssClass: "timeSlider",
- topLabelCssClass:"sliderTopLabel",
-
- noOfLabels: 3,
- timesliderType:"temp",
- sliderId:"tempId",
- showTopLabel: true,
- showPlayPauseBtn:true,
- showPreviousNextBtn:true,
- timeSlider:null,
- onsliderChange:function(timeExtentObj){},
- defaultIndex:0,
- _self:null,
- _unitTimeArray:{
- "esriTimeUnitsYears":0,
- "esriTimeUnitsMonths":0,
- "esriTimeUnitsWeeks":0,
- "esriTimeUnitsDays":1000 * 3600 * 24,
- "esriTimeUnitsHours":1000 * 3600,
- "esriTimeUnitsMinutes":1000 * 60,
- "esriTimeUnitsSeconds":1000,
- "esriTimeUnitsMilliseconds":0
- },
-
- constructor:function(params){
- dojo.mixin(this, params);
-
- _self=this;
- this.timeExtent=new esri.TimeExtent();
-
-
-
-
- this.sliderId=getUniqueId(this.timesliderType);
-
-
-
- },
- createSlider:function(){
- try
- {
-
-
-
- var tsDiv = dojo.create("div", null, dojo.byId(this.divId));
-
- this.timeSlider = new esri.dijit.TimeSlider({
-
- class:this.timeSliderCssClass,
- id: this.sliderId,
- options: {
- excludeDataAtLeadingThumb: true
- }
- },tsDiv);
- this.timeExtent.startTime = this.startDate;
- this.timeExtent.endTime = this.endDate;
- if (this.labels.length == 0) {
- this.labels.push(this.startDate.Format(this.labelFooterDateFormat));
- var balLabels = this.noOfLabels-1;
- var diff = this.endDate.getTime() - this.startDate.getTime();
- var increment = diff/balLabels;
- var firstTime = this.startDate.getTime();
- for (var i=1; i<this.noOfLabels-1; i++) {
- firstTime = firstTime + increment;
-
- this.labels.push((new Date(firstTime)).Format(this.labelFooterDateFormat));
- }
-
- this.labels.push(this.endDate.Format(this.labelFooterDateFormat));
- }
- this.timeSlider.setLabels(this.labels);
- this.timeSlider.setThumbCount(1);
- this.timeSlider.setThumbIndexes([this.defaultIndex]);
- this.timeSlider.setLoop(false);
- this.timeSlider.singleThumbAsTimeInstant(true);
- this.timeSlider.createTimeStopsByTimeInterval(this.timeExtent,1,this.timeUnit);
- if(!this.showPlayPauseBtn)this.timeSlider.playPauseBtn.destroy();
- if(!this.showPreviousNextBtn){this.timeSlider.previousBtn.destroy();this.timeSlider.nextBtn.destroy();}
-
- this.timeSlider.startup();
-
- var defaultBegainTime=this.timeSlider.getCurrentTimeExtent().startTime.Format(this.labelTopDateFormat);
- if (this.showTopLabel == true) {
- dojo.create("span", {id: this.sliderId+"_sp_topLabel",class:this.topLabelCssClass, innerHTML: defaultBegainTime}, dojo.query(".dijitSliderMoveable")[0]);
- }
- dojo.connect(this.timeSlider, "onTimeExtentChange",function(evt){
-
- if (_self.showTopLabel == true) {
- var topLabelDisplay= evt.startTime.Format(_self.labelTopDateFormat);
-
- dojo.byId(_self.sliderId+"_sp_topLabel").innerHTML = topLabelDisplay;
- }
- _self.onsliderChange(evt);
- });
- return this.timeSlider;
- }
- catch(e){console.dir(e);return null;}
- },
- _testsub:function(){
- console.dir(_self);
- alert(this.topLabelCssClass);
- }
- });
把上面的code存到一个文件名为MyTimeslider.js的文件中
使用slider只需要调用这个class
- <script src="MyTimeslider.js"></script>
divId是网页中要展示slider的位置上的<div> 的ID.
下面给出做test的HTML。

css中的一个图片文件dropDownArrow_grey.png是slider中向下箭头的图片,可以换成你喜欢的图片。
- 其中还有用到一个名为dateTimeFormat.js的文件,该文件是extend一个option给JavaScript的date object,增加了一个Format的option,
有了它,我们的slider的date format就简单很多了,
下面给出dateTimeFormat.js的code::
- Date.prototype.Format = function(mask) {
-
- var d = this;
-
- var zeroize = function (value, length) {
-
- if (!length) length = 2;
-
- value = String(value);
-
- for (var i = 0, zeros = ‘‘; i < (length - value.length); i++) {
-
- zeros += ‘0‘;
-
- }
-
- return zeros + value;
-
- };
-
- return mask.replace(/"[^"]*"|‘[^‘]*‘|\b(?:d{1,4}|M{1,4}|yy(?:yy)?|([hHmstT])\1?|[lLZ])\b/g, function($0) {
-
- switch($0) {
-
- case ‘d‘: return d.getDate();
-
- case ‘dd‘: return zeroize(d.getDate());
-
- case ‘ddd‘: return [‘Sun‘,‘Mon‘,‘Tue‘,‘Wed‘,‘Thr‘,‘Fri‘,‘Sat‘][d.getDay()];
-
- case ‘dddd‘: return [‘Sunday‘,‘Monday‘,‘Tuesday‘,‘Wednesday‘,‘Thursday‘,‘Friday‘,‘Saturday‘][d.getDay()];
-
- case ‘M‘: return d.getMonth() + 1;
-
- case ‘MM‘: return zeroize(d.getMonth() + 1);
-
- case ‘MMM‘: return [‘Jan‘,‘Feb‘,‘Mar‘,‘Apr‘,‘May‘,‘Jun‘,‘Jul‘,‘Aug‘,‘Sep‘,‘Oct‘,‘Nov‘,‘Dec‘][d.getMonth()];
-
- case ‘MMMM‘: return [‘January‘,‘February‘,‘March‘,‘April‘,‘May‘,‘June‘,‘July‘,‘August‘,‘September‘,‘October‘,‘November‘,‘December‘][d.getMonth()];
-
- case ‘yy‘: return String(d.getFullYear()).substr(2);
-
- case ‘yyyy‘: return d.getFullYear();
-
- case ‘h‘: return d.getHours() % 12 || 12;
-
- case ‘hh‘: return zeroize(d.getHours() % 12 || 12);
-
- case ‘H‘: return d.getHours();
-
- case ‘HH‘: return zeroize(d.getHours());
-
- case ‘m‘: return d.getMinutes();
-
- case ‘mm‘: return zeroize(d.getMinutes());
-
- case ‘s‘: return d.getSeconds();
-
- case ‘ss‘: return zeroize(d.getSeconds());
-
- case ‘l‘: return zeroize(d.getMilliseconds(), 3);
-
- case ‘L‘: var m = d.getMilliseconds();
-
- if (m > 99) m = Math.round(m / 10);
-
- return zeroize(m);
-
- case ‘tt‘: return d.getHours() < 12 ? ‘am‘ : ‘pm‘;
-
- case ‘TT‘: return d.getHours() < 12 ? ‘AM‘ : ‘PM‘;
-
- case ‘Z‘: return d.toUTCString().match(/[A-Z]+$/);
-
-
-
- default: return $0.substr(1, $0.length - 2);
-
- }
-
- });
-
- };
把四个文件准备好,就可以进行测试了
二次封装arcgis的timeslider
