Question

In the jquery below should there be a closing paretheses “)” before the “dot” in:

“.test($ …”?

(/^\s*$/.test($(this).val()))

$(document).ready(function () {
    $('#userlogin').css('color', '#cccccc').val('LOGINNAME');   

    $('#userlogin').blur(function () {
        if (/^\s*$/.test($(this).val())) {
            $(this).val('LOGINNAME');
            $(this).css('color', '#cccccc');
            $(this).valid();
        }
    }).focus(function () {
        if ($(this).val() === 'LOGINNAME') {
            $(this).val('');
            $(this).css('color', '#000000');
        }
    });

If not, why not? That code looks a little weird to me.

Answer 1

The code is correct:

/^\s*$/  // create a regex
  .test( // call the test method on it
    $(this) // create a jquery object
      .val() // call the val method on it
  )

However, the value could be cached: var val = $(this).val();.
Then the line might be less confusing to you: /yourregex/.test(val)
