For Servlet and Ajax interactions, the solution of status = parsererror is always reported. ajaxparsererror Cause: the data returned by the servlet is not in Json format. 1. JS code: Var jsonStr = {'clusternum': 2, 'iterationnum': 3, 'runtimes ': 4}; $. ajax ({type: "post", // http: // 172.22.12.135: 9000/Json. json url: "/LSHome", dataType: 'json', data: jsonStr, success: function (data, textStatus) {if (textStatus = "success ") {alert ("task creatio

Complex interactions) Multiple Dispatching) Processing various types of interaction may make the program quite messy. For example, consider a system that parses and executes mathematical expressions. You need to support numbers + numbers, numbers × numbers, and so on. The number here is the base class of a series of numeric objects. However, if we only give a + B and we do not know the exact type of A or B, how can we make them interact correctly? Th

Override ViewGroup and use ViewDragHelper to implement various drag-and-drop interactions, 1. If the previous SlideUpLayout control contains a list such as ListView or RecyclerView during use, the following problems may occur: The xml file is as follows: Ii.

In Android applications, the JavaScript code in WebView can be called directly, while the JavaScript code in WebView can also be called to the Android application (that is, the Java part of the code). The following examples illustrate:1 JavaScript script calls Android programTo call Addjavascriptinterface (Obj,interfacename) in WebViewwhere obj is an application that communicates with JavaScript, InterfaceName is provided for JavaScript calls.Name, set as follows:WebView WebView = new WebView (t

Android-communication with WEB interactions in the same SessionBoth Session, Cookie, and Session are used to save the status information of the client. They are all used to solve the problem of HTTP stateless. Session can be implemented using cookies or URL write-back. Cookie and Session have the following obvious differences: 1) Cookie stores the status on the client, and Session stores the status on the server; 2) cookies are small pieces of text st

When triggered, the text appears in color. An event is glue that glues all user interactions in an application. Dom and events are the Golden Partners in JavaScript

In the development process, we will inevitably use Ajax interaction, each need to write $http, but write more will find that this maintainability is not high, and duplicate code too much, not suitable for rapid development.such as this:$http ({URL: "test.php",Method: "POST",Data:JSON.stringify ({name: "Tao"}),headers:{"Content-type": "Application/json"}}). Then (function (data) {}), function (err) {}When your project is big enough, you'll find it annoying to write this often, with lots of repeti
