The Inavigationprovidercontext method can get an existing menu item, add a menu, or a menu item. As a result, different modules can add their own menus. Once you have created the navigation, you also need to register to the ABP configuration file when the corresponding module is initialized: Configuration.navigation.providers.add Show Me

The examples in this article describe the common API functions for JavaScript string objects. Share to everyone for your reference, specific as follows: 1. Concat (str1,str2,) Connection string 2. IndexOf (Str,start) Returns the position of the first occurrence of STR in a string var str = "Hello world"; Str.indexof ("Hello"); 0 str.indexof ("O", 5);//7 Str.indexof ("World");//-1 3. LastI

I got a Baidu map to mark the geographical location information and obtained the address through Baidu api. This map api is a javascript version. If you are interested, you can understand it. It may be helpful to you. Sometimes some things are not recorded, but when you look at it for a while, I will forget it. You need to read it again. Baidu map

Detailed description of the file upload API in JavaScript, javascriptapi For Web programmers, processing file uploads on webpages is always a very troublesome task. In the past, we were not able to upload images by dragging images, nor did we have complicated Ajax upload techniques. We seldom processed batch uploads of multiple files. We cannot obtain the information during the upload process, unless it is

; varDeferred =Identifytask.execute (identifyparams). Addcallback (function (response) {returnArrayutils.map (response, function (result) {varFeature =result.feature; varLayerName =Result.layername; Feature.attributes.layerName=LayerName; if(LayerName = = ='sde.heat') { varHeattemplate =NewInfotemplate ("Property Information", "Mine number:${kjbh}"); Feature.setinfotemplate (heattemplate); } Else if(LayerName = = ='Sde.geo') {

Javascript API mode: it helps us provide better and cleaner interfaces for functions. These modes mainly include the following: 1) callback mode: The function is also an object, so it can be passed as a parameter. See the following example: function demo01 (callback) {callback ();} function test01 () {console. log ("AAA") ;}demo01 (test01); // "AAA" Let's take a look at the callback and its scope: var myobj

It stores local data with the behaviour attribute of DHTML, allowing each page to store up to 64 K data, and each site can store up to k Data, the disadvantage of userData is obvious. It is not part of the Web standard, unless your program only needs to support IE, it is basically useless.3. Flash cookie. Flash cookies are not the same as HTTP cookies. They may be called "Flash local storage". By default, Flash cookies allow each

Research on Web worker multi-thread API in JavaScript, workerapi HTML5 supports APIs such as Web Worker, allowing Web pages to execute multi-threaded code securely. However, Web Worker is actually subject to many restrictions because it cannot truly share memory data and can only use messages for status notifications. Therefore, it cannot even be called a real "multi-thread ". The Web Worker interface is in

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

Query is one of the common functions of webgis. map-based query has evolved in many forms. Currently, there is no fixed mode for displaying the query in what form, which is suitable for webgis, what forms can meet the needs of applications. For example, to describe the most typical scenario, click the map to display a TIP small window, showing the simple information of the query object, the small window provides a "details" link, click it to display the data card on the webpage.
