Hello I've been creating a form on my computer and the jquery code doesen't seem to respond as it should i'll post the index.html and tmscript for you guys to see the problem ... HTML : <div id="form1" > <div id="name1" > <input type="text" id="namebox" placeholder="First name" name="user_name"> <div class="span1">!</div> </div> ....
JQuery:
$(".span1").hide(); $("#namebox").focus(function(){ if($("#namebox").length < 6) {$(".span1").show;} else {$(".span1").hide;} });
the problem is that is always remain hidden "the span1"(the span1 is a red circle with a ! in it ) and if i type in the console of the browser namebox.length it shows me "undefined" , it should show 0 right ?

Focus event will not be ideal to track the number of characters in the input field. For that purpose you should bind your function to keypress or keyup event. Please check this Codepen
