javascript - get element type from element found by class -

im trying create function "value" of type of element has specific class (textarea, span,... whatever)

to need test kind of element im dealing can enough alert($('#gdocdump').prop('tagname')); reason if grab elements of same class var varelems=$(".feedback"); , try loop through them testing each 1 var elementtype = elem.prop('tagname');, error "typeerror: elem.prop not function"

1. why happen?
2. apparently elements stored in jquery object created $(".feedback") not quite same looking @ each individually?
3. what need change var elementtype = elem.prop('tagname'); work below?

jsfiddle:testing ground

html

<textarea id="gdocdump" class="feedback area" rows="1" cols="22" ></textarea><br /> <input id="scaleslider" class="feedback" type="range"value="1" min="1"  max="9" step="1"/><br /> <span id="command1" class="feedback">this span</span><br /> <span id="command2" class="feedback">this span</span><br /><br /> <input type="button" id="sendfeedback" value="feedback"/><br /><br /><br /><br /> <input type="button" id="test" value="test specific element"/> 

javascript:

$("#sendfeedback").click(function() {         composeandcallemail(); });   $("#test").click(function() {         alert($('#gdocdump').prop('tagname')); });    function composeandcallemail() {     var varelems=$(".feedback");     var feedback=[];     $(varelems).each(function(index, element) {         feedback.push(getelemcontents(element))     }); }  function getelemcontents(elem){     var elementtype = elem.prop('tagname');     //this problem occurs     if(elementtype=='input')return elem.val();     //... add more here later } 

inside each(index, element) arguments index , native dom element

$(varelems).each(function(index, element) {      feedback.push(getelemcontents(element)) // plain dom element, not jquery }); 

that means have wrap again or use native elem.tagname property

function getelemcontents(elem){     var elementtype = $(elem).prop('tagname');     if ( elementtype.tolowercase() === 'input' )            return $(elem).val(); }
