Pagination feature for table listing inquirys

[DanielZambSB]

Pagination Algorithms

Variables and Definitions Q

• I: Array of inquirys with size [0, N)
• P: Pagination Array of pages with size [0, tp)
• i: Current index over P, 0 <= i < tp
  • P[i]: Page at index i, P[i] in P
• >: Next page, >(P,i) results in P[i+1], and changes direction to +1
• <: Previous page, <(P,i) results in P[i-1] , and changes direction to -1
• ps: Page sizes, {5, 10, 20, 50, 100}
• tp: Total pages, calculated as tp = Math.ceil(I.length / ps)
• gps: Group of pages size, gps = 3
• tgp: Total group of pages calculated as tgp = Math.ceil(tp / gps)
• j: Current index over a page group
  • PG[j]: page group at index j, PG[j] in PG
• PG: pagination "array" of group of pages with size [0,tgp)

Functions

showPages(Q)

1. tp := Math.ceil(I.length / ps)
2. tgp := Math.ceil(tp / gps)
3. r := tp % gps
4. if direction > 0
   1. if j=tgp-1 and r > 0:
      1. offset := j*gps
      2. redraw remainder 0 <= k < r size widget P[offset+k]
      3. hide the rest of the buttons
      4. Page(Q)
   2. If i % gps == 0:
      1. j := j+1
      2. offset := j*gps
      3. Change to PG[j] and P[offset]
      4. redraw full widget 0<=i<3, P[offset+i]
      5. Page(Q)
5. if direction < 0
   1. if i % gps = gps-1:
      1. j:=j-1
      2. offset := j*gps
      3. Change to PG[j] and P[offset]
      4. redraw full widget 0<=i<3, P[offset+i]

      5. Page(Q)

Page [Q]

1. If i = 0 then
   1. Disable <
2. If i = tp - 1
   1. Disable >
3. Mark P[i] as current
4. If > (P, i)
   1. i := i+1
   2. Change to P[i]
   3. Read I from [i*ps, (i+1)*ps)
   4. Redraw full inquiry list table
   5. Go to (3)
5. If < (P, i)
   1. i := i-1
   2. Change to P[i]
   3. Read I from [i*ps, (i+1)*ps)
   4. Redraw full inquiry List table
   5. Go to (3)

Additional Notes

• gps is the number of page indices to show at once.
• tp is the total number of pages, and ps is the current page size.
• i is the index of the current page.
• [i*ps, (i+1)*ps) indicates the range of indices from the input I to be displayed on the current page.
• The functions handle enabling/disabling of navigation buttons and updating the displayed range of items based on the page selection.
