html - Create new form fields on click using javascript -


i have form asks general information (i called gen-info) , fieldset inside form in ask other information.

what i'm trying create new fieldset asking same other info , rename it, know how create copy of whole form (which asks general info too).

by i'm creating button this:

<button type="button" id="btnaddform" onclick="cloneform('gen-info');">add other info</button>

and i'm using javascript function:

function cloneform(formname) {     var formcount = document.forms.length;     var oform = document.forms[formname];     var clone = oform.clonenode(true);     clone.name += "new form " + formcount;     document.body.appendchild(clone); }

click here see whole code

as can see, duplicate whole form, want duplicate part says "other information 1" , rename "other information 2" when click , add 1 name every time create new one. difference i'm duplicating whole form every time, , want duplicate fieldset.

thank much!

here how can these kind of operations jquery, ive commented each line can follow logic. html altered (you had no closing </fieldset>)

//on startup $(function() {     //add click event-handler button     $("#btnaddform").click(function() {         $clone = $("fieldset").last().clone() //clone last fieldset         $number = $clone.find("span") //get element number         $number.html(parseint($number.html()) + 1) //add 1 number         $("fieldset").last().after($clone) //insert new clone     }) })

and here entire thing, note jquery included script in dropdown left. https://jsfiddle.net/tx839gf3/4/

edit, heres 1 gives new names, theres new row in start, , 3 rows iterating on input-elements, , naming them:

$(function() {     var n = 4 //start naming elements number     $("#btnaddform").click(function() {         $clone = $("fieldset").last().clone() //clone last fieldset         $number = $clone.find("span") //get element number         $number.html(parseint($number.html()) + 1) //calc , set new number         //loop input fields in copied group         $clone.find("input").each(function() {             $(this).attr("name", "other-info-" + n++) //set new name-number (and iterate it)         })         $("fieldset").last().after($clone) //insert new clone     }) })
