Question

i have a input field that is accepting url from user and i need to check for trailing slash like so:

• http://www.example.com (add slash)
• http://www.exaple.com/ (ignore)
• http://www.example.com/index.php (ignore)

Try this –

function URLFormat() {
    var url = document.getElementById('inputURL').value;
    var urlParts = url.split("/")
    var result = '';
    for (i = 0; i < urlParts.length; i++) {
        if (i == urlParts.length - 1) {
            if (urlParts[i].indexOf('.') > -1) {
                // trailing slash not required
                result = url;
            }
            else {
                if (urlParts[i].indexOf('#') > -1) {
                    // trailing slash not required
                    result = url;
                }
                else {
                    //Assume this is a folder and add a slash
                    result = url + '/';
                }
            }
        }
    }
    alert(result);
}
