![]() Event Handling: jQuery also simplifies JavaScript event handling.On the other hand, selecting and manipulating DOM elements using raw JavaScript is messy and cumbersome. jQuery provides a powerful and supercharged selector function to select elements based on HTML tag-names (e.g.,, ), HTML ID attribute (e.g., #debug), and CSS class name (e.g. DOM Elements Selection and Manipulation: The "query" refers to querying and selecting DOM elements within a web document for subsequent manipulation.On the other hand, to provide cross-browser support in raw JavaScript, you need to check the browser and issue the appropriate codes, as different browsers (particularly IE) implement certain features differently. That is, the same jQuery code runs on the big-5 browsers (Chrome, Firefox, IE, Safari and Opera). Cross-Browser Support: jQuery provides cross-browser support.In other words, most of the developers nowadays program in jQuery, rather than raw JavaScript. Among the JavaScript libraries/frameworks, jQuery's market share is 95.2% (Ref: ). In May 2015, JQuery is used by 64.2% of all the websites. It is a small script (about 96kB minified) written in JavaScript called " jquery.js", which greatly simplifies JavaScript programming by providing cross-browser supports for DOM element selection and manipulation, event handling, Ajax request/response processing and animation. The above list is not exhaustive.JQuery ) is a JavaScript Library. Writes a line terminator to the text string or stream. Public Overrides Sub Write (value As String) Writes the text representation of a 4-byte signed integer to the text string or stream. Public Overridable Sub Write (value As Integer) Writes the text representation of an 8-byte floating-point value to the text string or stream. Public Overridable Sub Write (value As Double) Writes the text representation of a decimal value to the text string or stream. Public Overridable Sub Write (value As Decimal) Public Overrides Sub Write (value As Char) Writes the text representation of a Boolean value to the text string or stream. Public Overridable Sub Write (value As Boolean) The following table shows some of the most commonly used methods of this class − Sr.No.Ĭloses the current StreamWriter object and the underlying stream.Ĭlears all buffers for the current writer and causes any buffered data to be written to the underlying stream. The StreamWriter class inherits from the abstract class TextWriter that represents a writer, which can write a series of character. Guess what it displays when you compile and run the program! The StreamWriter Class ' Read and display lines from the file until the end ofĬonsole.WriteLine("The file could not be read:") Using sr As StreamReader = New StreamReader("e:/jamaica.txt") ' The using statement also closes the StreamReader. ' Create an instance of StreamReader to read from a file. The file reads −Īnd the sun shines daily on the mountain top The following example demonstrates reading a text file named Jamaica.txt. Reads the next character from the input stream and advances the character position by one character. ![]() Public Overrides Function Read As Integer Returns the next available character but does not consume it. Public Overrides Function Peek As Integer It closes the StreamReader object and the underlying stream and releases any system resources associated with the reader. The following table describes some of the commonly used methods of the StreamReader class − Sr.No. The StreamReader class also inherits from the abstract base class TextReader that represents a reader for reading series of characters. These classes inherit from the abstract base class Stream, which supports reading and writing bytes into a file stream. The StreamReader and StreamWriter classes are used for reading from and writing data to text files.
