Advanced java script

JavaScript has enhanced the simple html pages into more dynamic and interactive web pages. It is very easy to learn as it was designed keeping less experienced programmers in consideration. You can now decorate and design pages, adding real-time functionalities, and visual effects to attract the users with the help of advanced JavaScript.

The internet has a huge number of websites, so for a website to excel these days it has to stand out by using multiple functionalities to boost the speed and smoothen the web experience hence creating a dynamic web page with the help of JavaScript. It is a very small programming language but it is very malleable and flexible as it can be guided very easily for the end result.

The most common form of JavaScript usage is on the client side. For it to work successfully, it should be added or referenced inside the html code for the browser to present the end result. Writing your script directly into the html is the easiest way to implement the JavaScript.

Also, JavaScript uses it own object model which is inspired by the HTML content of the web page, Which is known as Document Object model (DOM). JavaScript enables the user to see the object and properties inside the web page such as frames, browser window, and status bar etc.

JavaScript can provide many enhanced features such as

Visual effects: This helps in decoration and nowadays Advertising.

Games: Interactive games are so much in demand online nowadays.

Banners: customized banners can help in delivering messages and warning.

Form Validation: Checking on the user details and reverting back with a response.

The major Areas of applications of JavaScript include:

1) Checking the user form entries: it saves time by validating the data types at the client end, rater than sending the data to the server and then validating it.

2) The use of banners and other visual effects requires user input and is displayed instantly with the help of a live script.

Ajax

Ajax (asynchronous JavaScript and XML) comprises of much programming abilities than the name suggests. The simultaneous searching and browsing without the disadvantage of refreshing or reloading the page, it refreshes the data instantly!

It helps in creating highly responsive web application rather than the old sluggish applications which required code submission for every function used.

The functionality of Ajax is much faster than the traditional web application as it tends to rely only on the patch of data with the help of JavaScript, which is needed to generate a response on the following page, rather than waiting for the data and recreating the entire page with refreshed data in the traditional web applications.

Some very good examples which made this partial page updating web application (Ajax) expand its usage are web-based email applications. Google maps too helped in presenting one of the usagesĀ of Ajax.

Ajax uses by default uses XMLHttpRequest (XHR) object instead of the older objects like image requests, inline frames, and the script tag. This also plays as a disadvantage as not all devices and browser supports this functionality.

Limited powers to parents in Delhi’s Edu Bills: Critics

NEW DELHI: On Friday,amid much drama, education minister Manish Sisodia tabled two bills that he evidently believes will alter the education scene in Delhi. Incidentally, the critics of the bills believe that too but for entirely different reasons. While intended to bring relief to parents and children, some who have reviewed the bills say they have “no role for parents” in them.

Lawyer and education activists Khagesh Jha “welcomes” the provisions on capitation fee and screening in nursery admissions but feels the The Delhi School Education (Amendment) Bill, 2015 is shoddily drafted and lifts safeguards on admissions into other classes. While the bill prohibits “screening” and “capitation fee” at entry-level, it says the “head of school may subject the child to any screening procedure for admission in class beyond elementary level.” This being placed in the act, argues Jha, effectively nullifies Rule 145 of the Delhi School Education Act and Rules 1973 that addressed admissions till Class 12 and contained provisions for admission tests. “Now schools can admit on the basis of your shirt-colour. There are schools that add entire sections after elementary,” says Jha. He also adds the definition of “entry-level” as “pre-primary” or “pre-school” may lead to schools adding classes at age two. “That is permissible by law.”

In Jha’s interpretation, the bills “don’t have any role for parents or children.” The proposed insertion, Section 27A (2), says offences shall be “non-cognizable and bailable and no court shall take cognizance of any offence under this act except on the complaint of an officer not below the rank of such officer as the government may authorise in this behalf.” Then, section 16(A)(3), says “Director (education) shall be the competent authority to impose the fine mentioned in section 16(A) (on screening and capitation fees).” “What this amounts to,” explains Jha, “is the directorate will complain, inquire and judge all cases related to capitation fee and screening.” The authority to impose fines was, till now, with the High Court by default. Jha further adds that no violation on the screening and donation front will lead to imprisonment as section 16(A) which addresses these has been excluded from the purview of section 27(A) on “offence and penalties.”

The complaints mechanism proposed in the Delhi School (Verification of Accounts and Refund of Excess Fee) Bill, 2015, is problematic too. Lawyer Ashok Agarwal had earlier described the proposed mechanism as “a trade-union negotiating and industrial dispute.” Section 7(1) of the bill says, “Any complaint relating to utilization of school fund or non refund of excess fee in terms of the order issued under sub-section (2) of section 6, may be made by parents of at least twenty students or one fifth of the total strength of students in such school, whichever is less, before the committee in such manner as may be prescribed.” “It is hard to fine one parent willing to challenge a school’s authority,” said Agarwal.

CISCE board revamps syllabus, pattern of question papers

BENGALURU: ICSE schools will go the CBSE way. The Council for the Indian School Certificate Examination (CISCE) board on Friday revamped its syllabus, infrastructure and training methods. The board took this decision in its 58th annual meeting with the objective to centralize education to frame class XII (ISC) question papers on the lines of CBSE pattern from 2018.

TOI was the first to report this last month . Accordingly, the specimen question papers for ISC exams 2018 in the following subjects physics, chemistry, biology, and maths have been prepared as per the pattern followed by CBSE, the specimen question papers deal with questions on recall, understanding, application, analysis and evaluation.

In class X (ICSE) level, syllabi for history, civics, geography, maths and physics have been reviewed for 2018 exams. This is to ensure that in addition to conforming to present day educational trends, the syllabus is also relevant, flexible, and meaningful in content.

Gerry Arathoon, chief executive and secretary of CISCE said specimen question papers have already been prepared on the CBSE pattern and the pattern is framed possibly with an eye on competitive exams conducted by the CBSE.

In keeping with the requirements of many Universities for higher education after Class XII, the break-up of marks of the theory and practical components at the ISC level, for the subjects – computer science, fashion designing, physical education, Indian music (Hindustani), carnatic and Western Music has been revised.

According to CISCE, the existing mark breakup of 50% theory and 50% practical has now been changed to70% theory and 30% practical, in order that these subjects be considered as elective subjects. This change will be effective from the ISC Year 2016 Examination onwards.

The specimen question papers for these subjects have already been sent to schools and are also available on the council website www.cisce.org
