how to solve this error

Jun.10,2021

if you want to take out every item in the array where the attribute pkPropertyOwnerId is not equal to w, you should return a new array with filter instead of repeatedly manipulating the current array.

var pt = this.propertylistIn;
// newPt
var newPt = pt.filter(function (item) {
    return item.pkPropertyOwnerId !== w;
})

this error means that pt [I] does not have pkPropertyOwnerId attribute


should be p = pkPropertyOwnerId==w 1, but if you do this, you will not be able to delete the adjacent pkPropertyOwnerId==w. You can use pt [I] .pkPropertyOwnerId! = w push new Array


.

splice will change the length of the original array, so it will appear that PT [I] is undefined, you can use filter, or this:

for (var i =0 ; i<this.propertylistIn.length;iPP){
    if(pt[i].pkPropertyOwnerId==w){
        pt.splice(i,1)
        i=i-1
    }
