I'm currently facing an issue with trying to locate the index of a number within a 2d array. The console is throwing an error that says:
Uncaught TypeError: block[((a * 10) + c)].indexOf is not a function
I suspect the problem lies in how I am accessing the elements in the array, but unfortunately, I haven't been able to pinpoint the exact cause.
Below is the code snippet in question:
var block = [];
var temp;
var del;
for(var a = 0;a < 9;a++){
for(var b = 0;b < 9;b++){
temp = parseInt(prompt("enter element number " + b + " of row number " + a));
console.log(temp);
if(temp>0){
block[a*10+b] = temp;
}else{
block[a*10+b] = [1,2,3,4,5,6,7,8,9];
}
// console.log(block[a*10+b]);
}
}
for(var a = 0;a < 9;a++){
for(var b = 0;b < 9;b++){
if(typeof(block[a][b]) == "number"){
for(var c = 0;c < 9;c++){
if(c != b){
del = block[a*10+c].indexOf(b);
block[a*10+c].splice(del,1);
}
}
}
}
}
