Eliminating all zero elements from an array

Question

Eliminating all zero elements from an array

Currently, I am working on a project involving Javascript and I need to eliminate zero values from an array that looks like this:

0 : Object  
     color : "#24a7e1",
     data  : Array[119],
     name  : "Active
     status : 2
1 : Object
     color : "#26a727",
     data  : Array[119],
     name  : Completed,
     status: 4

The number of objects in this array can vary, but my goal is to iterate through each one, access the 'data' attribute, and remove any zero values from it.

I tried handling a specific array with the following code:

for(var i=0; i<filteredValueData[0].data.length;i++ )
{ 
     if(filteredValueData[0].data[i] == 0)
         filteredValueData[0].data[i].splice(i,1); 
}

However, I encountered the error:

filteredValueData[0].data[i].splice is not a function

At this point, I'm uncertain about what I may be doing incorrectly. The object could contain anywhere between 0 and 5 arrays inside of it.

Answer №1

  filteredValueData[0].data[i].splice(i,1);

If you are looking to manipulate an element in an array based on the value of 'i', here is a suggested approach:

for(var i=0; i<filteredValueData.length;i++ )
{ 
    filteredValueData[i].data = filteredValueData[i].data.filter(function(item){return item !== 0})
}

  filteredValueData[0].data[i].splice(i,1);

There are a few issues with the current code snippet, I recommend trying out this updated version:

for (var i = 0; i < filteredValueData[0].data.length; i++) {
    if (filteredValueData[0].data[i] === 0) {
        filteredValueData[0].data.splice(i, 1); // Replace data[i] with just data
        i--; // Decrease the counter i
    }
}

Here is a simple example to illustrate the solution:

var array = [1, 2, 3, 0, 2, 1, 0, 2, 3];
for (var i = 0; i < array.length; i++) {
    if (array[i] === 0) {
        array.splice(i, 1); // Replace data[i] with just data
        i--; // Decrease the counter i
    }
}
console.log(array); //[1, 2, 3, 2, 1, 2, 3]
