Multiple choice javascript

You are a junior web designer. Your company assigns you to work on a JavaScript project. Which of the following are the advantages of using JavaScript for form validation?

  1. Conservation of client CPU resources

  2. Increased validity of form submission

E Correct answer
Explanation

JavaScript form validation provides multiple benefits: it increases validity by catching errors before submission (B), conserves bandwidth by reducing server round-trips for invalid data (C), and increases user satisfaction by providing immediate feedback (D). Option E correctly identifies all these advantages. Option A is incorrect because client-side validation uses client CPU resources, it doesn't conserve them.

  1. It is a new hybrid technology that is different from both XML and HTML.

  2. You can't use it to create Web pages.

  3. It is a reformulation of HTML in XML.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To solve this question, the user needs to have a basic understanding of web development and markup languages.

Now, let's go through each option and explain why it is right or wrong:

A. It is a new hybrid technology that is different from both XML and HTML. - This option is incorrect. XHTML stands for "Extensible Hypertext Markup Language", and it is a markup language that is based on XML. XHTML combines the syntax of HTML with the strictness of XML.

B. You can't use it to create Web pages. - This option is incorrect. XHTML is used to create web pages just like HTML.

C. It is a reformulation of HTML in XML. - This option is correct. XHTML is a reformulation of HTML in XML, which makes it easier for web developers to create valid and well-formed web pages.

D. It has totally replaced HTML as the tool for building Web pages. - This option is incorrect. Although XHTML has some advantages over HTML, it has not completely replaced it. HTML is still widely used for building web pages.

Therefore, the correct answer is:

The answer is: C

  1. It designs XML forms.

  2. It supports forms generated by Access Database.

  3. It has no server side form processing features.

  4. It has no client side form processing features.
Reveal answer Fill a bubble to check yourself

Which technique is referred to as inline scripting?

  1. The use of SCRIPT tags in line with the HEAD and BODY tags.

  2. The addition of the INLINE tag within the controlling HTML.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Inline scripting refers to placing script code directly within HTML event attributes (like onclick or onmouseover) inside the tags themselves. This differs from internal scripting (using SCRIPT tags in the head/body) or external scripting (linking to a .js file).

Which of the following is a more efficient alternative to CGI?

  1. ISAPI

  2. VB Script

  3. SGML

  4. HTML

  5. XML
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

ISAPI (Internet Server Application Programming Interface) is a more efficient alternative to CGI for Windows/IIS servers. Unlike CGI which creates a new process for each request, ISAPI runs in-process with the server, reducing overhead and improving performance. VB Script, SGML, HTML, and XML are not CGI alternatives.

CSS (Cascading Style Sheets) is the technology for handling multiple overlapping styles through specificity, inheritance, and cascade rules. Inline styles are part of CSS.

The ISINDEX tag (a deprecated HTML element for simple search queries) used the PROMPT attribute to override the default prompt text that appeared before the input field. There is no ASK or MESSAGE attribute in the HTML specification for ISINDEX, and it was possible to customize the prompt.

Multiple choice web-design

When you are hyperlinking to a page WITHIN your website, it is better to use which linking style?

  1. Absolute URL (http://www.site.com/directory/page.htm)

  2. Relative URL (../directory/page.htm)

Relative URLs are preferred for internal linking because they make the website portable. If the domain name changes or the site is moved to a different directory level, the links remain functional. Absolute URLs are rigid and harder to maintain for internal site structures.
