Seeking assistance on how to filter a table based on certain conditions. Refer to the sample image provided in the link below: https://i.sstatic.net/Egvj6.png
Here is the code I have attempted:
this.reportData.filter(it => {
if (
it.startTimeFilter.includes(this.startdatefilter) &&
it.endTimeFilter.includes(this.enddatefilter) &&
it.status.toLowerCase().includes(this.status)
) {
this.filteredData.push(it);
}
});
Sure, I can provide you with some tips on how to achieve this without sharing the entire code. Just remember to never modify this.reportData as all data must be retained for filtering purposes.
applyFiltering(){
this.dataToShowOnUI = getFilteredData();
}
getFilteredData(): any[]{
let filteredData = JSON.parse(JSON.stringify(this.reportData));
if(this.startdatefilter && this.enddatefilter){
filteredData = filteredData.filter(it =>
it.startTimeFilter.includes(this.startdatefilter) &&
it.endTimeFilter.includes(this.enddatefilter)
);
}
if(this.status){
filteredData = filteredData.filter(data => data.status.toLowerCase().includes(this.status))
}
if(this.operatingSystem){
filteredData = filteredData.filter(data => data.operatingSystem.toLowerCase().includes(this.operatingSystem))
}
// and so on ...
return filteredData;
}
If we assume that the variables this.reportData and this.filteredData are arrays, then using the filter method correctly would look like this:
this.filteredData = this.reportData.filter(item =>
item.startTimeFilter.includes(this.startdatefilter) &&
item.endTimeFilter.includes(this.enddatefilter) &&
item.status.toLowerCase().includes(this.status)
);
In essence, the filter parameter should be a function that returns a boolean value (indicating whether the element should be retained), resulting in a new filtered array without altering the original one.
