How to delete unchecked value

Preetham Thangamma

Good Evening,

i am trying to delete the notification number from "this.ary" when the respective checkbox is unchecked in the grid view in the else condition which is not happening in the following typescript....so,please do the needful!!

for (let i = 0; i < eleData.length; i++) {
var str = this.ary;
var notVal = str.includes(Notification_No);
if (eleData[i].checked && notVal==false) {
checkBoxSelectedItems1.push(Notification_No);
this.ary +=Notification_No+","
}
else if (!eleData[i].checked && notVal==true)
{
checkBoxSelectedItems1.pop();
// this.ary=str.slice();
}
}

Good Evening,

this.ary="NTF202086,NTF202085," and i want to delete only NTF202085 when pop() is used but it is deleting entire NTF202086,NTF202085

Thank you

Please share which part or items from array or string, you want to remove.

i cannot use str.splice(i,1); as str is a string and it doesn't support splice

it is showing "eleData.splice is not a function" error in console when i used eleData.splice(i,1);

Use Splice() function for removing items from array.

Syntax:
array.splice(index, number of elements);

Use splice instead of slice.
eleData.splice(i,1);

Try this

this.ary = str.splice(i,1);
