Question

I’m rendering some HTML in which I inject the value of a textbox with javascript.
See: {$T.blob.title}

<input type="text" maxlength="40" size="16" id='imgtitle_{$T.blob.Id}' value='{$T.blob.title}' class="imagetitleinput" /><br />

However, this string may be null so the textbox shows the value "null" to the visitor.
How can I check (preferably inline) if the value of {$T.blob.title} is null and if so set the value of this textbox to ""?

I’m using this template engine: http://jtemplates.tpython.com/

This should work [Using Jquery]

$(document).ready(function () {
    $(".imagetitleinput").each(function () {
        if($.trim($(this).val()) == '') {
            $(this).val('NULL');
        }
    });
}) 

Though not sure if you want to use Jquery here or not.
