I need to generate html table dynamically and list driver_id underneath. It is something similar to pivot but the problem is zone_name can change every day. I'm using jquery and linq.js.
so far what I have tried:
var data =
[
{
"ColorCode": "green",
"StatusName": "ACTIVE",
"rankId": 0,
"zone_name": "Zone A",
"driver_id": 100,
"zone_rank": 1,
"status_id": null,
"company_id": null,
"updated_on": null,
"Driver": null,
"login_status": null
},
{
"ColorCode": "yellow",
"StatusName": "BREAK",
"rankId": 0,
"zone_name": "Zone B",
"driver_id": 101,
"zone_rank": 1,
"status_id": null,
"company_id": null,
"updated_on": null,
"Driver": null,
"login_status": null
},
{
"ColorCode": "green",
"StatusName": "ACTIVE",
"rankId": 0,
"zone_name": "Zone A",
"driver_id": 102,
"zone_rank": 4,
"status_id": null,
"company_id": null,
"updated_on": null,
"Driver": null,
"login_status": null
}
]
var zTable = document.getElementById('tblZoneRank');
var allzones = Enumerable.From(data)
.Distinct(p => p.zone_name)
.Select(p => p.zone_name).ToArray();
$.each(allzones, function (i, item) {
var tr = document.createElement('tr');
var td = document.createElement("td");
var txt = document.createTextNode(item);
td.appendChild(txt);
tr.appendChild(td);
var childItem = Enumerable.From(data)
.Where(p => p.zone_name == item)
.ToArray();
$.each(childItem, function (j, citem) {
var ctd = document.createElement("td");
var ctxt = document.createTextNode(citem.driver_id);
ctd.appendChild(ctxt);
$(ctd).css('background-color', citem.ColorCode);
tr.appendChild(ctd);
});
zTable.appendChild(tr);
});
It is giving me output in this way:
<table id="tblZoneRank">
<tr>
<td>Zone A</td>
<td style="background-color: rgb(0, 128, 0);">100</td>
<td style="background-color: rgb(0, 128, 0);">102</td>
</tr>
<tr>
<td>Zone B</td>
<td style="background-color: rgb(255, 255, 0);">101</td>
</tr>
</table>
but I need output in this format: It should display zone_name as column name and underneath driver_id and first id should be zone_rank 1 and 2 and so on..
Am not familiar with linq.js so I used native array method Array#reduce()
and Map
object to create unique zones
const $table = $('#zoneTable');
// creates Map object with zone names as keys and arrays of jQuery objects(cells) as values
const zoneMap = data.reduce((map, item) => {
const col = map.get(item.zone_name) || [createCell(item.zone_name)];
col.push(createCell(item.driver_id, item.ColorCode));
return map.set(item.zone_name, col);
}, new Map());
// convert Map values to array of arrays. Each sub array is a table column
const colCells = [...zoneMap.values()];
const totalRows = Math.max(...colCells.map(e => e.length));
for (let i = 0; i < totalRows; i++) {
const rowCells = colCells.map(col => col[i] || createCell());// fill any missing with empty cell
const $row = $('<tr>').append(rowCells);
$table.append($row)
}
// helper function to create cells
function createCell(text = '', color = null) {
const $td = $('<td>').text(text);
return color ? $td.css('background-color', color) : $td;
}
