Question

I’m new in jquery and javascript coding and I tried to write a function that restores an initial value on a textarea if the length of its value is less than “n” characters. It doesn’t work. Can you explain me how to do that?

Here’s the code:

$("textarea").focus(function() {
    var text = $(this).val();
    $(this).val('');
    $(this).blur(function() {
        if($(this).val().lenght<20)
        {
            $(this).val(text);
        }
    });
});

Though not very efficient, this would do the work:

var text='';

$("textarea").focus(function() {
    text = $(this).val();
});

$("textarea").blur(function() {
    if($(this).val().length<20)
    {
        $(this).val(text);
    }
});
