Seeking assistance with customizing the sorting function for a Date column in a primeng table. Currently, the column is displaying data formatted as 'hh:mm a' and not sorting correctly (e.g. sorting as 1am, 1pm, 10am, 10pm instead of in chronological order). I have implemented a customSort function, but it is still producing the same incorrect sorting results specifically for the date column. Everything else in the table sorts properly except for this date column. Any suggestions or help would be greatly appreciated?
customSort(event: SortEvent) {
event.data.sort((data1, data2) => {
let value1 = data1[event.field];
let value2 = data2[event.field];
let result = null;
if (value1 == null && value2 != null) {
result = -1;
} else if (value1 != null && value2 == null) {
result = 1;
} else if (value1 == null && value2 == null) {
result = 0;
} else if (typeof value1 === 'string' && typeof value2 === 'string') {
const time1 = Date.parse('1970-01-01 ' + value1);
const time2 = Date.parse('1970-01-01 ' + value2);
console.log(value1);
if (time1 < time2) {
result = -1;
} else if (time1 > time2) {
result = 1;
} else {
result = 0;
}
} else {
result = value1 < value2 ? -1 : value1 > value2 ? 1 : 0;
}
return event.order * result;
});
}
I have also made some adjustments to the code but the sorting outcome remains the same.
customSort(event: SortEvent) {
event.data.sort((data1, data2) => {
let value1 = data1[event.field];
let value2 = data2[event.field];
let result = null;
if (value1 == null && value2 != null) {
result = -1;
} else if (value1 != null && value2 == null) {
result = 1;
} else if (value1 == null && value2 == null) {
result = 0;
} else {
const time1 = new Date(`1970-01-01 ${value1.padStart(5, '0')}`);
const time2 = new Date(`1970-01-01 ${value2.padStart(5, '0')}`);
const timestamp1 = time1.getTime();
const timestamp2 = time2.getTime();
if (timestamp1 < timestamp2) {
result = -1;
} else if (timestamp1 > timestamp2) {
result = 1;
} else {
result = 0;
}
}
return event.order * result;
});
}
