Edit Question
Title
Body
I have this HTML: <input type="text" name="textField" /> <input type="submit" value="send" /> How can I do something like this: When the text field is empty the submit should be disabled (disabled="disabled"). When something is typed in the text field to remove the disabled attribute. If the text field becomes empty again(the text is deleted) the submit button should be disabled again. I tried something like this: $(document).ready(function(){ $('input[type="submit"]').attr('disabled','disabled'); $('input[type="text"]').change(function(){ if($(this).val != ''){ $('input[type="submit"]').removeAttr('disabled'); } }); }); …but it doesn't work. Any ideas?
