Parsing XML data with JavaScript is a common programming task that JavaScript can do, and jquery can certainly do. Let's summarize some examples of using jquery to parse XML.The first scenario: Yanshi The second scenario: The general steps are as follows:1. Read the XML file$.get ("XMLFile.xml", function (XML) {//xml is the content that can be read, read see 2nd});2. Reading XML contentIf the read XML is coming from an XML file, this is combined
(deprecate). Java recommends providing information in Javadoc to inform the user why this method has been deprecated and what the workaround is.3. @SuppressWarnings – This note simply informs the compiler that ignoring them produces a special warning, such as the use of primitive types in Java generics. Its persistence strategy (retention policy) is source and will be discarded in the compiler.Let's look at an example that shows how to use built-in annotations, as well as the custom annotations
number (with decimal point symbol) %g floating-point numbers (%e or%f depending on the size of the value) %g floating-point number (similar to%g) %p pointer (memory address with hexadecimal print value) %n the number of stored output characters into the next variable in the parameter list Examples of string-related operations # string Alignment Word = "version3.0" # 20 characters Middle aligned Print Word.center (20) # 20 characters on each s
