Why You Should Use JavaScript on Your Site

Why You Should Use JavaScript on Your Site Not everyone has JavaScript available in their web browser and a number of those who are using browsers where it is available have it turned off. It is therefore necessary that your web page be able to function properly for those people without using any JavaScript at all. Why then would you want to add JavaScript to a web page that already works without it? Reasons Why You May Want to Use JavaScript There are several reasons for why you may want to use JavaScript on your web page even though the page is usable without the JavaScript. Most of the reasons relate to providing a friendlier experience for those of your visitors who do have JavaScript enabled. Here are a few examples of proper use of JavaScript to improve your visitors experience. JavaScript Is Great for Forms Where you have forms on your web page that your visitor needs to fill out that form content will need to be validated before it can be processed. You will, of course, have server-side validation that validates the form after it is submitted and which reloads the form highlighting the errors if anything invalid has been entered or mandatory fields are missing. That requires a round trip to the server when the form is submitted to perform the validation and report the errors. We can speed up that process significantly by duplicating that validation using JavaScript and by attaching much of the JavaScript validation to the individual fields. That way the person filling out the form who has JavaScript enabled has immediate feedback if what they enter into a field is invalid instead of their filling out the whole form and submitting it and then having to wait for the next page to load to give them feedback. The form works both with and without JavaScript and provides more immediate feedba ck when it can. A Slideshow A slideshow consists of a number of images. In order for the slideshow to function without JavaScript the next and previous buttons that work the slideshow need to reload the entire web page substituting the new image. This will work but will be slow, particularly if the slideshow is only one small part of the page. We can use JavaScript to load and replace the images in the slideshow without needing to reload the rest of the web page and so make the slideshow operation much faster for those of our visitors with JavaScript enabled. A Suckerfish Menu A suckerfish menu can operate entirely without JavaScript (except in IE6). The menus will open when the mouse hovers over them and close when the mouse is removed. Such opening and closing will be instant with the menu just appearing and disappearing. By adding some JavaScript we can have the menu appear to scroll out when the mouse moves over it and scroll back in when the mouse moves off of it giving a nicer appearance to the menu without affecting the way the menu works. JavaScript Enhances Your Web page In all appropriate uses of JavaScript, the purpose of the JavaScript is to enhance the way the web page works and to provide those of your visitors who have JavaScript enabled with a friendlier site than is possible without the JavaScript. By using JavaScript in an appropriate way you encourage those who have a choice as to whether they will allow the JavaScript to run or not to actually have it turned on for your site. Remember that a number of those who do have a choice and who have chosen to turn JavaScript off have done so due to the way in which some sites completely misuse javaScript so as to make their visitors experience of their site worse rather than better. Dont you be one of those using JavaScript inappropriately and therefore encouraging people to turn off JavaScript.

Western Classical music Essay Example | Topics and Well Written Essays - 250 words

Western Classical music - Essay Example y, which is very different from â€Å"Messiah† by George Frideric Handel which is an example of a baroque music with so much emotions attached to it and less instrumentation. The need to distinguish words more clearly in the music from all that instrumentation and to put emotion into the music was what necessitated baroque music to be developed during that era. The music was developed soon after renaissance music era ended and the start of this new era marked the beginning of emotion-revoking classical music which had other different musicians from the preceding era (Hall, 265). Compare the careers of Bach and Handel. How were they similar and how were they different? Talk about where they worked their reputations during their lifetimes, and the kind of music they wrote. Did Handel write types of music Bach didnt? Handel’s music career had first been hindered by his parents but his talent led them to change their mind. Bach was from a musician’s family and his singing was nurtured from a tender age. Both of these men loved classical music and they also had a rough patch before they became famous and reputable in music. Both had to teach music though in different countries and later on stopped the teaching. Handel was a violinist who worked in London and concentrated more on oratorios than operas towards the end of his career. Bach on the other hand was a music director in Leipzig. Handel had more reputation than Bach although Bach became famous after his death. Handel wrote operas and finally oratorios while Bach wrote orchestra music (Hall,

Goals Statement Essay Example for Free

Goals Statement Essay When I first sat down to write my educational goals statement, I thought it would be easy. I am an extremely goal oriented person, with my entire life being spent focusing on â€Å"what’s next†. So, how difficult could it be to simply write down those goals? When I began writing, however, I discovered it was going to be a little more difficult than I anticipated. I realized that it may be possible to have too many goals. My list was long and confusing with some goals very specific, and others vague. I thought to myself, how can I produce a smart goals statement out of this? So I re-evaluated my list and discovered that my goals could actually be divided into three predictable categories: immediate goals, short-term goals, and long-term goals. I decided then to choose one from each category to focus on for this report. My immediate goals were fairly general, but all related to my success as a student, so my main goal as student is to get an A in all of my online subjects, and this is a goal that I will go reaching slowly, day by day over the course of this course and in my following online courses. I feel a little intimidated when taking these online courses because my native language is Spanish and having to study in English is an extra challenge for me but I know that with effort and dedication I will get the A that I’m hoping for.

Critics of The Adventures of Huckleberry Finn Essay -- Adventurous Huc

Critics of The Adventures of Huckleberry Finn   The Adventures of Huckleberry Finn is considered by many to be the greatest American novel ever written.   Despite this praise, Mark Twain’s masterpiece has never been without criticism.   Upon its inception it was blasted for being indecent literature for young readers because of its lack of morals and contempt for conformity.   Modern indignation toward Huck Finn arises from its racist undertones, most notably Twain’s treatment of the character Jim.   As is the case with many canonized yet controversial books, the biggest conflict revolves around the inclusion of Huck Finn on required reading lists of public schools throughout the country.   In general, the mostly African-American critics consider Twain himself to be racist and Huck Finn simply reflects this.   Blacks, especially Jim, are portrayed as fools and used as comedic fodder to bolster feelings of white superiority in Twain’s southern audience.   Although Jim’s positive qualities are presented in certain parts of the novel, they are overshadowed by his superstitious folly which Twain returns to in the later chapters.   The fact that Huck’s narration is intentionally skewed by the innocence and ignorance of an adolescent is little consolation to critics who feel that Twain has committed gross immorality.   Also, the incessant use of the epithet â€Å"nigger† has been deemed excessive.   Despite these condemnations though even the staunchest opponents of Twain find certain redeeming qualities that make it hard to promote all out censorship. One of the most stringent dissenters of Huck Finn is Julius Lester, Newberry Award winning author of the children’s book To Be a Slave.   Lester argues that one of the primary concerns of lit... ...hite man.   This pseudo-parenthood relieves Huck of any lifelong responsibilities to Jim and also allows Twain to eventually separate the two without any emotional repercussions.   In short, they lack a true familial bond implicating a tragedy of sadness at the core of their relationship which is possibly due to Huck’s insatiable racism. Ultimately, both Henry and Morrison approve the teaching of Huck Finn under the conditions of mature students and cautious, open-minded teachers.   The problems in Twain’s novel may never be fully explained but an honest and careful consideration of the issues in Huck Finn should contribute positively to the growing awareness of American race relations.    Work Cited Clemens, Samuel.

Old Mrs Grey

â€Å"Old Mrs. Grey† Born in 1882, Virginia Woolf was an author, feminist, critic, essayist, pacifist and one of the founders of the Modernist Movement in Literature. Like many of her contemporaries in the Movement, she employed a vivid and descriptive stream-of-consciousness writing style that was rooted in the popular Freudian psychoanalytic theories of the day; and in fact, both of her brothers became psychoanalysts. Woolf regarded herself as â€Å"mad†, having bouts of debilitating depression brought on by her bi-polar disorder. Within her body of work, especially in her essay â€Å"Old Mrs.Grey†, you can see the melancholic/suicidal ideation of her own psyche deployed in the character of Mrs. Grey. She did not hold with the traditional views that suicide was sinful or cowardice. In 1941, she put rocks in her coat pockets and committed suicide by drowning herself in a river near her home in Sussex. The letter she left reasoned that she was â€Å"going mad ag ain and shan’t recover this time†. This is the background on how and possibly why Mrs. Woolf uses the imagery of hopelessness so effectively in this story as a surrogate for her own misery.In the story â€Å"Old Mrs. Grey†, Woolf’s depressively artful use of words describes a lonely 92 year old woman whose body has painfully palsy, â€Å"jerked her body to and fro†, and is in constant arthritic pain which, â€Å"twists her legs† and keeps her confined to her home where she sits in a â€Å"hard chair† and looks with â€Å"aged eyes† that have â€Å"ceased†. She sits by a dying fire in a hard chair, looking at â€Å"The morning spread seven foot by four, green and sunny. â€Å" a reference to the only life she knows now, looking through the door of her cottage at the life outside of it.This is emblematic of her longing for a bygone youth, which Woolf further describes, â€Å"†¦ (she) saw herself at ten, at twenty, a t twenty-five. †, a youth which has fled and left her nothing but memories. The poignant aspect of the story is that while Mrs. Grey is confounded by her longevity, though she longs for the Lord to â€Å"take her†, she never actually voices a propensity to end it herself. The author clearly feels that the advances of medical science that prolong her life, which are but a, â€Å"nail†¦that pinions†¦the body against a wall†, are an insult and occur seemingly against her will.However, as the protagonist notes, the doctor is a good man. The author implies that the doctor is in wonder that Mrs. Grey hasn’t died, but clearly shows that he takes care of her, as required by his oath, regardless of his personal opinion. Clearly, Woolf’s use of imagery and diction brings the reader into Mrs. Grey’s end of life suffering and morose loneliness. The reader, by the end of the story, can empathize with Mrs. Grey’s feeling of the pointlessne ss and uselessness of her remaining days and her longing to â€Å"pass on†, because of Woolf’s competent characterization of Mrs. Grey’s somber situation.
