input selected when submitting the form is uploaded, interacting with the database, but this is something. 3. Submission of the form, The type attribute's submit is the most commonly used method of submitting a form, giving the type a value value that can be displayed directly on the Submit button. In addition, the submit submission of the form needs to be opened to the form Label actin property to specify the action of the form when it is uploaded, and if omitting the action attribute does no

mysql| Basics Tutorial SQL in MySQL For MySQL, the first thing you have to keep in mind is that each line of its command is separated by a semicolon (;) As the end, but ... There is no complete absolute thing, and here is the same. As I mentioned earlier, when a row of MySQL is inserted into the PHP code, it is best to omit the semicolon, for example: mysql_query ("INSERT into TableName" (First_Name, Las

, you can resize the picture, dynamically edit the CSS style rules, change the form method from Get to post (or vice versa), and there are many more. We have also introduced some advanced JavaScript technologies, such as object-oriented programming. First, you learned how JavaScript uses a prototype based mechanism to simulate inheritance. It then learned how JavaScript uses private properties that can only be accessed through public methods to support the concept of information hiding. Finally

this tool is called extrusion (crunching), and simply deletes all comments and line breaks. The documentation for this tool is said to save 20%~50% bandwidth. Using the crunch mode, you can see that the size of the JavaScript file is reduced by 30%. The highest level of compression in this tool is called compression (compressing), is a real compression mechanism for the actual compression of JavaScript source code, and to the file to increase the automatic decompression function. The documenta

XMLHttpRequest object, you need to check the type of browser. A real business-like protocol can reduce this code-writing effort. Basically, loading and saving the specification provides a common API for Web developers to access and modify the DOM in a platform-and language-independent way. In other words, whether your platform is Windows or Linux, it doesn't matter whether you're developing it in VBScript or using JavaScript. You can also save a DOM tree as an XML document, or load an XML docum

You might want to know what the difference between get and post is and want to know when to use them. Theoretically, if the request is idempotent, get can be used, and the so-called idempotent means that multiple requests return the same result. In fact, the corresponding server method may modify the state in some way, so this is generally not true. This is just a standard. The more practical difference is in the size of the net charge, and in many cases the browser and the server restrict the U

the browser supports ActiveX controls. It is appropriate to know if the browser is Internet Explorer. If it does, create a XMLHttpRequest object by instantiating a new instance of ActiveXObject, and pass in a string indicating what type of ActiveX object to create. In this example, the string provided for the constructor is microsoft.xmlhttp, which means you want to create an instance of the XMLHttpRequest. If window. ActiveXObject call fails (returns NULL), JavaScript will go to the Else stat

of tricks to circumvent the Internet's trouble limits. With a variety of remote scripting methods and HTML elements, developers can communicate asynchronously with the server, but the real cross-browser approach is possible until a mainstream browser provides support for the XMLHttpRequest object. Companies such as Google, Yahoo and Amazon are already ahead of us, and we can see that browser-based applications are also comparable to those of fat customers. With Ajax, you can take advantage of b

developers jump out of the Ajax details. However, you still have to know something about JavaScript. We know that JavaScript can be difficult to use. But unfortunately, there is no way to do that. Most of us have learned this trick, "alert" as a type of system output to help debug, unfortunately, this technology is widely used. But now we have a new weapon. In addition to JavaScript, you need to familiarize yourself with other techniques associated with presentation, such as HTML, DOM, and CSS

study magnetic fusion energy, In addition, a csnet was created to carry out computer science research, funded by the National Science Foundation (Foundation). Tim Berners-lee of the European Centre for Particle Physics (CERN) in 1989 presented a very interesting concept. Instead of simply quoting other people's writings, he thought, would it be better to have practical links? When reading an article, the reader can open other articles that are referenced. Hypertext (hypertext) was quite popula
