In fact, there are two examples of ArcGIS API for JavaScript, but there are some parameters that are not clearly explained. An example of ArcGIS is a service published by GeoServer as an example, and here is an independent Geowebcache service WMTS service, the address is HTTP://LOCALHOST:8080/GEOWEBCACHE/SERVICE/WMTS, The example given by ArcGIS has not been tuned for two days, as in the following example (

One, what is DOM? What do you mean Dom,dom is the Document Object model, a set of API interfaces that are based on browser programming (in this tutorial, DHTML programming), the recommended standards for the Web, and each browser has some subtle differences, One of Mozilla's browsers is closest to the standard. Simple JavaScript can be used to make DHTML programming with DOM in order to make a beautiful eff

has not been able to adhere to the habit of blogging, after n months once again write a blog, is also the first technical blog, the example project is two or three months ago in the school wrote, writing is also relatively simple, the first contact API development, mostly just divert, their programming ability needs to improve. A brief introduction to this example, the main function of the example is to display the location of Guangzhou tourist attrac

Esri/configThe object used to modify some configuration. Only one Property object Defaults,defaults object has four properties: Geometryservice string,kemlservice string,map Object,io objects. We can set the following:　　Require (["Esri/config"],function(esriconfig) { EsriConfig.defaults.geometryService= ""; // ......});According to this object, we can set the Geometryservice,kmlservice, can set the map movement, the rate of scaling, the time (move, zoom map speed), Slider,sliderlabel,zoom

Setcustomvalidity () Method:Sets the Validationmessage property of the input element, which is used to customize the method of the error message.Note: When a custom prompt is set with setcustomvalidity, the validity.customerror becomes true, and checkvalidity () always returns false, resulting in the correct format of the re-entry, or Will prompt you to set the error message.Workaround: Use Obj.validity.patternMismatch to judge, if the input format is correct, will setcustomvalidity empty, so th

Fetch () Does the same thing as XHR, but fetch return a promise.Fetch'Password.txt', { 'Method':'PUT', 'Headers': { 'x-something-nothing':'Fetch rocks!'}}). Then (response= { if(Response.Status = = = $){ returnresponse.text ()}Else{ Throw "cannot fetch data"}}). Then (data={console.log (data);}).Catch(Err ={console.error (Err)})Check the reponse API here:linkBesides text (), you can use JSON () or BLOB ().' No-cors ' and opaque responsesIf

the formatting you've just set up has a corresponding display on the pop-up window.There is a layer of vectors in the Mapview, which is featurelayer. (I can see that ESRI's stroke algorithm for vector graphics is not very good, the sharp place is not as good as the desktop version, it should be the problem of buffer algorithm)Sum up.To customize a specific feature layer or graphic set the following steps:1. Instantiating the map and view objects2. Create a Popuptemplate object that can be creat

The ArcGIS Server for JavaScript API must know Infowindow. When you use Infowindow, you will find various problems, such as problems that cannot be fully displayed, problems covering objects, and so on. So I was in the realization of this function when the brain, I want to use DIV+CSS to get one, Daoteng for a long time, made up a for example, see the following:Do more ugly, the style has to work hard.

modularization. The previous specification as a module is too large and complex. Therefore, it is divided into small modules and more new modules are also added. These modules include: Box Model, list module, hyperlink mode, language module, background and border, text effects, and multi-column layout. 3) jquery is another excellent protocol Cr protocol PT framework after prototype. It is a lightweight JS Library (only 21 K after compression). It is compatible with css3 and various browsers (I

1. Call () and apply (), examples are as follows:function Add (A, B){alert (A+B);}function Sub (A, b){Alert (A-B);}Add.call (sub,3,1);Note: This example means that the sub inherits Add,add.call (sub,3,1) = = Add (3,1), so the result is: alert (4); Note: The function in JS is actually an object, and the function name is a reference to a function object.Note : Replace with sub, which adds an Add method to sub now;i.e. Add.call (sub, 3, 1);EquivalentSub.add = function Add (A, B){alert (A+B);}A diff

Javascript uses call to call API, callapi The code is very simple. I just want to give you a thought. There is not much nonsense here. Here is the source code: Copy codeThe Code is as follows: Here is just an introduction to the idea. Let's take full advantage of the specific friends.

If you are not familiar with event events, it is recommended to read my previous text javascript: Understanding DOM events. Or look directly below the worker API.First, we need to instantiate a worker object, and the browser will open a new interface based on the newly created Worker object, which will handle the communication between the client and the INDEXEDDB database. The database here refers to the browser database. If you need to determine whet
