How Do I Retrieve The Whole Word Ending At Specific Index In JS?
I know the end offset of a word , how can I get this word length (or find the index of the last space character before this word)
In the example below, I know the offset is 11 which is "k" but I want to get whole word "Back" or till the space.
var offset = 11;
var myString = 'Welcome Back Here';
console.log(myString.charAt(offset));Ad
Answer
You can use something like this
var offset = 11;
var myString = 'Welcome Back Here';
var idx = 0;
// Iterate backword and check for space
for (var i = offset; i >= 0; i--) {
if (myString.charCodeAt(i) == 32) {
idx = i + 1;
break;
}
}
var result = myString.slice(idx, offset+1);
console.log(result)Ad
