Question

I have strings like Name:, Call:, Phone:….and so on in my table. I am learning jQuery and was able to access the text. My tutorial has used trim() to remove any whitespaces. But I want o remove “:” from the end of each string (and yes, it always lies in the end after calling trim() method). So how to achieve it.

Its my code:

<script type="text/javascript">
    $(function ()
    {
        $(':input[type=text], textarea').each
    (
    function ()
    {
        var newText = 'Please enter your ' +
    $(this).parent().prev().text().toLowerCase().trim();
        $(this).attr('value', newText);
    }).one('focus', function ()
    {
        this.value = '', this.className = ''
    }).addClass('Watermark').css('width', '300px');
    });
</script>

trim(“:”) did not help…

Answer 1

You can replace all : characters:

var str = '::a:sd:';
str = str.replace(/:/g,''); // str = 'asd';

Or use a handy rtrim() function:

String.prototype.rtrim = function(character) {
    var re = new RegExp(character + '*$', 'g');
    return this.replace(re, '');
};

var str = '::a:sd:';
str = str.rtrim(':'); // str = '::a:sd';
