Object Annotations (JSON) is a text format that is similar to XML and can be used to exchange data. JSON design to ensure that two aspects, on the one hand easy to read, on the other hand easy machine parsing, it uses the C-series language similar to the Convention. Also associated with JSON is JSON-RPC, a remote procedure call (RPC) protocol that resembles XML-RPC, but is oriented to the JSON language. As a statute, JSON-RPC is implemented in many languages, including Java, Ruby, Python, and P

with the server Exchange data, so if directly embedded in the JSP code to judge, then back to the page to the JSP variable value is actually the last exchange data with the server after the cache value, will not execute JSP code. Then must require the use of HTML code with the server data exchange, that is, with JS to communicate with the server, this must use Ajax. If you use the DWR framework, you will need to obtain the SESSION,

easily Use menus and tab pages) tree Structure, calendar, text editor, and other effects. Of course, non-synchronous Ajax functions are also supported. In addition, because Ajax uses dynamic operations on file objects, users cannot use previous pages or next pages, or use functions like "My favorites, correct bookmarks are left on the pages required by the user, but these requirements have been addressed by Dojo. Compared with other lightweight Ajax frameworks, it is obvious that it takes a lot

think it's difficult to get started with javascript, but it's just a little difficult to debug. I had to output alert without stopping. Later I learned about firebug, and sometimes I used breakpoints. However, most of them are easy to use alert. HTML: it is not difficult to get started. After all, most of them use open-source examples for the interface. CSS: simple. IDE: Uses myeclipse, which is more comprehensive than eclipse integration. For novice web Development recommend that everyone's we

AJAX development, debugging is more complicated because it needs to identify whether the error is generated by the client or the server. In the past, the JavaScript debugging method was to delete all the code and add a row until the error occurs. Now, more developers return to Microsoft Script Debugger for IE and Venkman for Mozilla Browser. Browser compatibilityThe biggest problem with JavaScript programming comes from the support of various technologies and standards by different browsers. Bu

Invoke Java methods remotely in the browser's JS code. 1. Remote, asynchronous invocation of Java methods requires an extra pass in a parameter. A parameter is a callback function that is shaped like function (data) {}. Where data represents the return value being invoked. 2. When Java

Let's talk about something that seems irrelevant to the title. With the popularity of ajax frameworks such as prototype DWR,The server generates js Code and returns it to the client. Calling (direct call or eval) by the client seems to have become a normal practice (I don't know if it is popular ). This method (actually a design) is understandable, but often misunderstood and applied.(Here the so-called "error" is based on my position. Maybe more peop
