Locating numerous words within a given string

Locating numerous words within a given string

In my quest to identify specific words within a comma-separated log, I have encountered an issue. The current code snippet effectively locates individual words, but struggles to find all three words together in the log.

$log = "Left Side Turn, Left Side Road, No Turn, Left, Right Turn";
var currLog = $("#log").text();

var theName = "Left Side Road";      //target phrase...

var currLogWords = currLog.split(/\b/);
        var hits = [];
        for (var i = 0; i < currlogWords.length; i++) {
            if (theName == currlogWords[i]) {
                hits.push(currlogWords[i]);
            }
        if (hits == 0) { do something } else { do other }

Answer №1

Your current code has a typo with currLogWords written as currlogWords, so it will likely result in an error like currlogWords is not defined.

To search for the complete string, you can try the following:

var log = "Left Side Turn, Left Side Road, No Turn, Left, Right Turn";
    var currLog = $("#log").text();

    var theName = "Left Side Road";      //this is the target string to search for...

    var currLogWords = log.split(',');
            var hits = [];
            for (var i = 0; i < currLogWords.length; i++) {
                if (theName.trim() == currLogWords[i].trim()) {
                    hits.push(currLogWords[i]);
                }
            }
            if (hits == 0) { 
                console.log(hits.length); 
                } else { 
                    console.log(hits);
                    console.log(hits.length); 
                }

When utilizing the split() function, the parameter specified determines how the string's content will be divided. Instead of currently using \b to split at any word break (such as a space), consider changing it to a comma to exclusively divide the string at commas. It is also important to eliminate leading and trailing whitespaces after splitting to remove any additional whitespace around each item separated by a comma.
