value undefined for jquery

Question

here is my jquery

 var obj=$("#Connect");
  alert($("#Connect").value);

The value appeared to be undefined, but I have a html tag there

<input type="button" id="Connect" value="Connect"/>

what is the problem?

you are mixing jquery and javascript here...correct way to get value in jquery is val()

try this

jquery

alert($("#Connect").val());

javascript

 alert(document.getElementById("Connect").value);

@william007 http://api.jquery.com As a rule you don't access any attributes directly. The jQuery object is not the same thing as the DOM element it refers to. – JJJ Mar 25 '13 at 12:31
@Juhana, wow, the list is long to memorize – william007 Mar 25 '13 at 12:32

That's why the list is there so you don't have to :) – JJJ Mar 25 '13 at 12:33
