I have a string filled with ones and zeros separated by "," and ";".
var x = "1,1,0;1,0,0;1,1,1;"; x.split(";");
This results in an array containing only two strings: 1,0,0 and 1,1,1.
My goal is to organize these numbers into a two-dimensional array:
1 1 0
1 0 0
1 1 1
If there is a more efficient method than just splitting the string, please share it with me.
Otherwise, please advise on how to correct the issue mentioned above.
This is a possible solution:
var str = "1,1,0;1,0,0;1,1,1";
var arr = str.split(";");
for (var i = 0, len = arr.length; i < len; i++)
{
arr[i] = arr[i].split(",");
}
To check the outcome:
for (var i = 0, len = arr.length; i < len; i++)
{
for (var j = 0, len2 = arr[i].length; j < len2; j++)
{
document.write(arr[i][j] + " | ");
}
document.write("<br>");
}
consider this string:
var x = "1,1,0;1,0,0;1,1,1";
By using the following code snippet, you can convert it into a two-dimensional array of zeros and ones:
var st = x.split(";");
var twoDimensionalArray = st.map(function(k){
return k.split(",");
});
Utilizing JS method chaining, you can achieve the same result more efficiently:
var twoDimTable = x.split(";").map(function(k){
return k.split(",");
});
The resulting array would look like this:
[
["1","1","0"],
["1","0","0"],
["1","1","1"]
]
If you want the numbers instead of strings in the array:
[
[1,1,0],
[1,0,0],
[1,1,1]
]
You could iterate through the array values and perform k = +k; to convert them from strings to numbers. However, JavaScript automatically performs type casting when mixing these values with numerical operations.
