jQuery loop through characters in an array of strings and find its index

Question

var tags = ["abcd", "aaacd", "ade"];

I'm trying to loop through each string in the array and find its index. Again loop through characters in each string and find its index (eg.)

$.each(arr, function( index, value ) {
    $.each(value.split(""), function( i, v ) {
        alert( i + ": " + v );
    });
});

@Mohammad -- I tried split. It didin't work$.each(arr, function( index, value ) { $.each(value.split(""), function( i, v ) { alert( i + ": " + v ); }); }); — dragonfly

You have to split() the value with empty string so that it becomes an array and you can implement .each():

value.split('')

var tags = ["abcd", "aaacd", "ade"];
$.each(tags, function( index, value ) {
  $.each(value.split(''), function( i, v ) {
    alert( i + ": " + v );
  });
});

First you have to convert string to array inside first each

var tags = ["abcd", "aaacd", "ade"];
$.each(tags, function( index, value ) {
     var va=value.split('');
    $.each(va, function( i, v ) {
        alert( i + ": " + v );
    });
});

You could use a nested Array.from and map at the end the index and value.

var tags = ["abcd", "aaacd", "ade"],
    result = Array.from(tags, (s, i) => Array.from(s, (c, i) => [i, c]));
    
console.log(result);

There are numerous way of handling this problem. You could also use the .entries() in a for of loop:

var tags = ["abcd", "aaacd", "ade"];
for (var val of tags) {
  for (var [idx, char] of val.split('').entries()) {
    console.log(idx + " : " + char);
  }
};
