Create and sort multi-dimentional array

I'm writing an classic ASP page.  I have a 1 dimentional array with the data like this: (FileName-Date-Content)


This is a test - 03 Apr 2000 - Test 1
Another test - 12 Dec 2003 - Test 2
Test again - 22 May 2012 - Test 3
Test number 4 - 09 Jun 2008 - Test 4

How can I display the latest date first so the data looks like this:

Test again - 22 May 2012 - Test 3
Test number 4 - 09 Jun 2008 - Test 4
Another test - 12 Dec 2003 - Test 2
This is a test - 03 Apr 2000 - Test 1

Thanks!

Do you have to bring in all 800 rows of data at once?  Or is it easy to  page through?   If you do have to bring them all in at once, I would really go the js/jquery route and sort in the browser.  It will be much faster.

Lets look at datatables using a javascript array as an example http://datatables.net/release-datatables/examples/data_sources/js_array.html

We just need to get the data in this form in no  particular order.
"aaData": [
            /* Reduced data set */
            [ "Trident", "Internet Explorer 4.0", "Win 95+", 4, "X" ],
            [ "Trident", "Internet Explorer 5.0", "Win 95+", 5, "C" ],
            [ "Trident", "Internet Explorer 5.5", "Win 95+", 5.5, "A" ],
            [ "Trident", "Internet Explorer 6.0", "Win 98+", 6, "A" ],
            [ "Trident", "Internet Explorer 7.0", "Win XP SP2+", 7, "A" ],
            [ "Gecko", "Firefox 1.5", "Win 98+ / OSX.2+", 1.8, "A" ],
            [ "Gecko", "Firefox 2", "Win 98+ / OSX.2+", 1.8, "A" ],
            [ "Gecko", "Firefox 3", "Win 2k+ / OSX.3+", 1.9, "A" ],
            [ "Webkit", "Safari 1.2", "OSX.3", 125.5, "A" ],
            [ "Webkit", "Safari 1.3", "OSX.3", 312.8, "A" ],
            [ "Webkit", "Safari 2.0", "OSX.4+", 419.3, "A" ],
            [ "Webkit", "Safari 3.0", "OSX.4+", 522.1, "A" ]
        ],

If you are getting this data as in array is this part
This is a test - 03 Apr 2000 - Test 1
how it comes in or is it array(0,0), array(0,1), array(0,2)?

If it is not an array, we can split the row of data.
str="This is a test - 03 Apr 2000 - Test 1"
array=split(str,"-")
text1=array(0)
date=array(1)
text2=array(2)

Once we have that we can simply create the js we need.
response.write "<script>"
' response.write each line of the sample to match your needs
response.write "["
for each line in httppost
   array=split(str,"-")
   response.write "'['"&"'"&array(0)&"',"& array(0) &"',"&array(0)&"'],"
       ' do a test for end of the line so you don't print out the very last comma
next
response.write "],"
' response.write the rest of the js needed as sample

Open in new window

800 rows is a lot, but this will make it go faster.

Get it to work with static data first.  

With dates, https://editor.datatables.net/release/DataTables/extras/Editor/examples/dates.html you just need to give it the dateformat as sampled.

Is the data hard coded out does it come from a database, where you could sort by using the order by clause?

Hi Big Monty,

I used MSXML2.ServerXMLHTTP to get the data from other web page so I cannot sort by date.

Thanks

Scott Fell, EE MVEDeveloper & EE ModeratorCommented:
If you need to sort the array, it is much faster to do this client side than using vbs.  

You can either write the data to a js/jquery array and sort using the timestamp.   If you need to get this out to a table, I like  using data tables.  http://datatables.net/release-datatables/examples/basic_init/table_sorting.html  It can be a bit much for just one small item, but if you are doing this a lot, it makes sense.

Otherwise, it is explained in 4guys how to sort arrays in asp/vbs http://www.4guysfromrolla.com/webtech/011001-1.shtml but there are better methods.  Big Monty is on the easiest track by using sql.    I would use vbs arrays sorting as a last resort.

If you still want to go into that in detail, let us know.

Hi Padas,

About 800 rows.  would you please help!

ttta83Author Commented:
Padas,

would you please run this code?  I have the data displayed on the screen but I want to sort by the year... It takes about 90 seconds for the page to load 'cause I have to go through each individual file to get the distinct first 3 characters of each file.   WHat should I do to make it run faster and with the list sorted by the dates.  

Without using jQuery, can we make it sort by date?

Please let me know if you have any questions.  

Again, thank you very much for your help on this.
