JavaScript: Splitting strings with multiple delimiters

Question

JavaScript: Splitting strings with multiple delimiters

Can I use a Java Script function to divide a string into multiple parts?

var string = "This is a test text, again, this is a testing text";

For instance, I can split the string using , like this: string.split(','); resulting in:

var string = ["This is a test text", "again", "this is a testing text"];

Now, I am interested in splitting the string based on specific parameters, so the string array would be:

var string = ["test text", "testing text"]

I am seeking a function that can extract all the sections of the string that start with test and end with text.

It seems you're asking for a solution, so here is a function I quickly put together in 2 minutes to address the scenario:

var string = "This is a test text, again, this is a testing text";

function customSplit(str_to_split, start_string, end_string) {
    var res = [];
    var start_index, end_index;

    for (i = 0; i <= str_to_split.length; i++) {
        start_index = str_to_split.toLowerCase().indexOf(start_string.toLowerCase(), i);
        if (i == start_index) {
            end_index = str_to_split.toLowerCase().indexOf(end_string.toLowerCase(), i);
            if (end_index >= 0) {
                res.push(str_to_split.substring(start_index, end_index + end_string.length));
            }
        }
    }

    return res;
}

console.log(customSplit(string, "test", "text"));

When used with the given sentence, it will return ["test text", "testing text"].
