Development ). XMLHttpRequest object An object You Want To Know may be the most unfamiliar to you, that is, XMLHttpRequest. This is a JavaScript Object. It is easy to create this object, as shown in Listing 1. Listing 1. Creating a New XMLHttpRequest object This object will be further discussed in the next article. Now you need to know that this is the object for processing all server communications. Befo

most important part of AJAX is to use the XMLHttpRequest object to send requests. The XMLHttpRequest object targets IE7 and later, Firefox, Chrome, Safari, and Opera, for IE5 and IE6, ActiveXObject is used. The method for creating an object is as follows: var xmlHttpRequest; if (window. XMLHttpRequest) {// XMLHttpRequest exists, indicating IE7 and other mainstream browsers. XmlHttpRequest = new XMLHttpRequest ();} else {xmlHttpRequest = new ActiveXOb

supports the track number. One byte space allows ID3 V1.1 to support a maximum of 255 track numbers. Considering the possibility of more than 256 tracks for a single record, this improvement is quite reasonable. ID3 format ID3v1 ID3V1 is relatively simple. It is stored at the end of an MP3 file. Open an MP3 file in a hexadecimal editor and view the 128 bytes at the end of the MP3 file. The data structure is defined as follows: Char Header [3];/* the label Header must be "TAG"; otherwise, no l

shown above, we registered the Middleware supporting the MVC Framework (actually a routing-based middleware, we also registered the corresponding middleware by calling other extension methods to achieve access to static files (UseStaticFiles), error page rendering (UseExceptionHandler), and ASP-based..

latency, the computing efficiency relative to the CPU is relatively large overhead. WhilePartial merge can merge intermediate results to reduce the size of data to be written/transmitted, thus improving algorithm efficiency.. Good local merge operations are crucial to efficient mapreduce algorithms. Local merge is achieved through two methods: Design a suitable combiner to merge the intermediate results generated by Er er. Use context information in a single mapper Local merge can effective

Squid is an application-level proxy. After the client host and server host are connected over the network, you must set the client software before using Squid, for example, set the proxy server address and port for Internet Explorer.The WEB Cache function is necessary for a large and busy network. An article on the IBM website details the benefits of WEB Cache for Internet users:Http://www-900.ibm.com/developer... achinga/index.shtml Next we will introduce the content of squid. § Install and run

successfulxmlHttpSet the variable to false to indicate that the code is faulty. If this happens, it may be because a non-Microsoft browser is installed and different code is required.Processing Mozilla and non-Microsoft browsersIf the selected browser is not Internet Explorer, or you want to write code for a non-Microsoft browser, you need to use different codes. In fact, it is a simple line of code shown in Listing 1:var xmlHttp = new XMLHttpRequest

calculate the coordinates of the mouse click position as the origin in the upper left corner of the Div, as shown below:You can see, click on the div near the upper left corner, its offsetx and offsety is 1, 0, it should be noted that Ie,chrome,opera support the property, but Firefox does not support the property, Firefox, the concept corresponding to this property is, Event.layerx and Event.layery, so whe

1.doctype(文档类型) 的作用是什么？ Validation of the document:It tells the user agent and the validator that the document was written according to what DTD. This action is passive,Each time the page loads, the browser does not download the DTD and checks for legitimacy, which is enabled only when the page is manually validated. Determines the rendering mode of the browser: for the actual operation, tell the browser which parsing algorithm to use whe

When Netscape first developed the Mozilla browser, it was wise to decide to support W3C standards. Therefore, the legacy code of Mozilla, Netscape Navigator 4.x, and Microsoft Internet Explorer is not fully backward compatible.. Internet Explorer 4 These browsers created before the emergence of W3C standards inherit a lot of weirdness. This article will discuss Mozilla's special mode, which provides powerful HTML backward compatibility functions for Internet Explorer and other legacy browsers. I

I suddenly thought that I could use the js split method to calculate the number of 1. The split parameter is regular \ 0 * \, which separates 1 in the s
