Javascript programming help

[5v3d3b0]

Right, if nobody wants to help me out I understand it, but I'm in serious shit. Coursework in for tomorrow, and I'm lost beyond imagination. I don't even understand what they're asking me...
Here's the spec:

[5v3d3b0]

These are the questions, then I have to write a page or 2 explaining why I've used the scripts I've chosen. How screwed am I? I can't see the light at the end of this one :/

i) function URL(page) - to return the URL part (not including the brackets) part of page (which is a string). [Note that this function will not contain an alert]
Example call: URL("[www.lboro.ac.uk]Loughborough University offers degree programmes and world class research. ")
Example result: "www.lboro.ac.uk"

ii) function content(page) - to return the content part (not including the URL) part of page (which is a string). [Note that this function will not contain an alert]
Example call: content(pages[0])
Example result: "Loughborough University offers degree programmes and world class research. "

iii) function find1C(s,p) - p is a number which is an index to the pages array and thus identifies one particular page. The function is to discover if the string s appears in the content (not the URL) part of page p. Gives an alert message containing the value of s together with either the text 'found' or 'not found'. [Note that s need not be a full word so that if p was 0 and s had any of the values "programmes", "programme", "program", "prog", "rog", "og", or "g" the result would be 'found' but if s had the value 'PROG' the result would be 'not found' because this is a case sensitive search. ]
Example call: find1C("prog",0)
Example result:
example result iii
[Note: The image above and two others below were added 9/11/2010 to replace the previous textual representation of the Example result.]

iv) function findAnyU(s) - to discover if string s appears in any of the URLs in the array pages. Gives an alert of s together with 'found' or 'not found' as for find1C. [Note that the search should be case insensitive so that 'lboro' and 'Lboro' and 'LBORO' would all be found in 'www.lboro.ac.uk' - all remaining functions should also be case insensitive in this way]
Example call: findAnyU("Lboro")
Example result:
Example result iv

v) function findIdxsC(s) - to return a string containing the indexes in the pages array where s was found in the content part, e.g. "prog found in pages 0,3,5,6,9" [Note that this function will not contain an alert]
Example call:findIdxsC("prog")
Example result:"prog found in pages 0,3,5,6,9"

vi) function findScoresC(s) - to return an array of scores for each content string in the pages array. [Score 0 for string s not found, 1 for string s found once, 2 for string s found twice, etc. Try to ensure that your program does not find s more than once in each word - e.g. if s='w' then it should be found twice in "The WWW. Hello world", not four times. ]
Example call: scores=findScoresC("prog")
Exploring the (array) result: alert(scores[2])

vii) function sortScores(scoreRecs) - to take an array of score records (each containing a score and a page index) return a sorted version where the records are arranged in descending order of score.
Example call: sortScores( [ { score:0, index:0 }, { score:2, index:1 }, { score:1, index:2 } ] )
Example result: [ { score:2, index:1 }, { score:1, index:2 }, { score:0, index:0 } ]

viii) function findScoreC2(s) - to find scores information as in findScoresC but return it in an array of records suitable as data for function sortScores. However this time the score is not just a straight count of the number of matches but a percentage score. The percentage score is obtained by the number of times the pattern occurs in the page divided by the number of words in the page, expressed as a percentage.
Example call: findScoreC2("prog")
Example result (an array): [ { score:0, index:0 }, { score:20, index:1 }, { score:10, index:2 } ]

ix) function findRanked(s) - to find scores information as in findScoresC2 and sort them as in sortScores and to finally return a string containing '(URL, %)\n' pairs where the percentage scores are in descending order.
Example call: findRanked("prog")
Example result: (www.lboro.ac.uk, 20%)
(www.other.com, 10%)
(www.zzz.tv, 1%)

x) function findMulti(wds) - to discover if any of the words in wds appear in the string pages[0]. This is a multiword search. The value for wds could be "univ deg LOUGH". Gives an alert of 'found' if any combination of 'univ' or 'deg' or 'LOUGH' is found.
Example call: findMulti("univ deg LOUGH")
Example result:

Thanks for the support

[Astridax]

Are You given a list of websites that need to be searches through. If so it's easy. Order them alphabetically, have two arrays, one ordered by url, the other content. Then have a function like this:

Function search (var term:string) : string
((while term != ArrUrl(i).value
next I) else
Return ArrUrl.value
)

Call on something like this

On button click do
Search (urlbox.text)

Have similar boxes and arrays for content. Sorry I can't help you with the language specifics, I don't know java too well? Something that will change by the end of the academic year. Sorry about the fail formatting, typing this off my phone.

This is why you should listen in skool instead of getting other peeps to do your work for you.....

If it is not to late,
i would suggest submitting whatever you have done so far...
If your uni is anything like mine,
no submission = fail (fail module),
Submit a pile of shite = shite mark but can do a referral!

So the bare arsed face of it is if your screwed, aim for a refurral...

Best of luck, it isnt the end of the world.

[Kickstart]

Hi

Do you still need to do this or did you cobble something together?

All the best

Well, I don't need it any more cause hand in has passed. I ended up getting 2 questions from my mate just to hand something in, but I'm screwed anyway. There is enough of the module left for me to pass the year, but it's gonna be tight :/

[The Shaggy D.A.]

Don't worry about it, just leave it until the night before and post a request for help on BCF.

you need to look into Python, google uses a lot of Python.
Write your user interface using PHP, and some of your back-end using Python or PERL, the core indexing routines are better written in 'C'


Adding a simple google search to your website:

<form method="get" action="https://www.google.com/search">

<input type="text" name="q" size="31"
maxlength="255" value="" />
<input type="submit" value="Google Search" />
<input type="radio" name="sitesearch" value="" />
The Web
<input type="radio" name="sitesearch"
value="askdavetaylor.com" checked /> Ask Dave Taylor<br />

</form>

alert('Java' == 'JavaScript' ? 'Yes' : 'No');

[Frost]

No.
ECMAscript as Sun, now oracle own the Javascript name, though Java can't be trademarked as it's an island.
Java + web page = Applet == epic fail.

[Astridax]

Tell me if my code worked. I'd have tested it if I was near my comp.

[paledude101]

Hehehe Monotone Stone's module?? I did this in first year, can't remember how though!
