open textfield after click on span does not work

I am not able to create an edit in place feature with JavaScript/ jQuery. I could not use the plugin editinplace, because I need to put a datepicker on it. My code below does not work for some strange reason:
function editImpfDatumImpfung1Clicked(sender)
{
var sText = $(this).text();
var sId = $(this).attr("id");
$(this).attr("id", "tobechanged");
$(this).after('<input type="text" id="' + sId + '" value="' + sText + '" />');
$(this).remove();
bImpfung1Clicked = true;
$("#" + sId).focus();
$("#" + sId).datepicker(datepickerOptions);
if (bFirstRegisterImpfung1 === true)
{
firstRegisterImpfung1();
bFirstRegisterImpfung1 = false;
}
}
$(document).ready(function()
{
$elem = $("span[id^='impfung_1['");
if ($elem.length > 0)
{
bFirstRegisterImpfung1 = true;
$elem.click(editImpfDatumImpfung1Clicked);
}
});
Edit:
No Errors in console.
console.log($("#" + sId).val()); causes undefined
Edit 2:
Just needed to escape the id like this:
sId = sId.replace(/[[]/g,'\\[');
sId = "#" + sId.replace(/]/g,'\\]');
Thanks for your advice.

I imagine you have a typo in the following line:
$elem = $("span[id^='impfung_1['");
try this instead:
$elem = $("span[id^='impfung_1']");

Append increasing number on click

I'm trying to append an increasing number to elements on click. I can't seem to make it work.
My code:
$('#on').click(function() {
$("b").click(function(e) {
var numCount = ($("[span class='num'>").length + 1);
var element = $("<span class='num'>" + numCount + "'>" + numCount + "</span>");
$(this).append(element);
});
});
I think It's a simple syntax error in my code, but I'm learning here so I could be completely wrong. It's important for the class to be added too.
Here's a Fiddle

Change
var numCount = ($("[span class='num'>").length + 1);
to
var numCount = ($(".num").length + 1);
You need to find .num elements, not create new ones.
In addition, your element line doesn't create valid HTML either. Try the following:
var element = $("<span class='num'>" + numCount + "</span>");

Clone DIV and its contents with new ids [duplicate]

This question already has answers here:
Clone <div> and change id
(4 answers)
Closed 9 years ago.
I'm trying to clone a div and the input elements inside it. When I clone it, I would like all the ids to increment by one. I've made a fiddle to show you what I'm doing.
$("#add").click(function (e) {
var amount = $('div.classes').length;
var new_amount = amount + 1;
var cloned_div = $('#class-' + amount);
$(cloned_div).clone().attr('id', 'class-' + new_amount).insertAfter('#class-' + amount);
});
jsFiddle
So far I've cloned the whole div itself and the ids increment but the elements inside remain the same. How would I get all elements inside the div to increment by one?

You have cloned the entire div without modifying it's contents. Try something like:
$("#add").click(function (e) {
var amount = $('div.classes').length;
var new_amount = amount + 1;
var cloned_div = $('#class-' + amount);
$(cloned_div).clone().attr('id', 'class-' + new_amount).insertAfter('#class-' + amount).find('input').each(function (i, e) {
$(e).attr('id', $(e).attr('id').replace(amount, new_amount));
});
});
DEMO

You can recursively replace all id's using find / replace:
$("#add").click(function (e) {
var amount = $('div.classes').length;
var new_amount = amount + 1;
var cloned_div = $('#class-' + amount).clone();
cloned_div.insertAfter('#class-' + amount);
cloned_div.find('[id$="-' + amount + '"]').andSelf().each(function(index, child) {
child.id = child.id.replace("-" + amount, "-" + new_amount);
});
});
See jsFiddle
cloned_div.find('[id$="-' + amount + '"]') will search for all child elements having an id attribute ending on "-" + amount, .andSelf() will include the cloned div as you want to change the id there also. Then simply replace the number part in the id of each child (and self).

Try adding this:
$('#class-' + new_amount + ' input:nth-child(1)').attr('id', 'name-class-' + new_amount);
$('#class-' + new_amount + ' input:nth-child(2)').attr('id', 'number-class-' + new_amount);
$('#class-' + new_amount + ' input:nth-child(3)').attr('id', 'book-class-' + new_amount);
just below your $(cloned_div).clone() statement.
See it in action:

These other answers are close, but the problem with their solutions is the original ID prefixes are being lost: number-class-1 is becoming class-1 which is not ideal.
Here is a better option:
$("#add").click(function (e) {
var amount = $('div.classes').length;
var new_amount = amount + 1;
var cloned_div = $('#class-' + amount);
var $cloned = $(cloned_div).clone().attr('id', 'class-' + new_amount).insertAfter('#class-' + amount);
$cloned.children().each(function(){
var $child = $(this);
var oldID = $child.attr('id');
var newID = oldID.replace(/[0-9]+$/, new_amount); // replace just the number, leave the rest of the ID name in tact
$child.attr('id', newID);
})
});
And a working example

Is it possible to use cloneNode to clone multiple divs?

I'm trying to clone to divs in and append them to to other divs (their parents). I'm using clonenode for this but it doesn't seem to work. It clones the div in the first function and appends it to the parent of the div in the second function! Not sure what I'm doing wrong.
Here's the code (*EDIT:*var added):
function cloneQ() {
//Cloning questions and shit
cloneQ.id = (cloneQ.id || 0) + 1;
var question = document.getElementById("question");
var clone = question.cloneNode(true);
var numberOfQuestions = $('.question').length;
var id = "questioncon" + cloneQ.id;
clone.id = id;
question.parentNode.appendChild(clone);
var inid = "question" + cloneQ.id;
var optionid = "optionsdiv" + cloneQ.id;
$('#' + id + ' ' + '.' + 'questionin').attr('id', inid);
$('#' + id + ' ' + '.' + 'options').attr('id', optionid);
$('#' + id + ' h2').html('Question ' + cloneQ.id);
//Question Cloned
}
function cloneforPrint() {
cloneforPrint.id = (cloneforPrint.id || 0) + 1;
var questionprint = document.getElementById("questionprint");
var cloneprint = questionprint.cloneNode(true);
var printid = "questionprint" + cloneforPrint.id;
cloneprint.id = printid;
questionprint.parentNode.appendChild(clone);
var printinid = "thequestionprint" + cloneforPrint.id;
$('#' + printid + ' ' + '.' + 'thequestionprint').attr('id', printinid);
}

Edit : Global vars are the problem.
You aren't putting var in front of your variables, making them global. The cloneForPrint function is picking up vars defined in cloneQ.
Init all the variables properly and you'll get some errors indicating where the problems are.
CloneQ is indeed appending to questions parent, but cloneForPrint then moves it somewhere else.
-- Old answer --
There's not enough here to work out what the problem is. My 1st guess is that the question element has the same parent as the questionprint element.
Based on the code given, cloneQ should definitely append to questions parent. So to give the appearance you've specified the DOM probably doesn't look like what you expect.

jquery using multiple setTimeouts

I am currently creating a site with some dynamic content, so that whenever a user hovers over a label, the label expands to show more information, then after a specific time the label will collapse again, unless the user hovers over the label again in which case the Timeout will reset. I have developed the code to do this for 1 label, but I would to develop it now to do it for multiple labels.
The problem I'm having though is that I am defining the variable for the timer globally so it can be used for both events, this won't work when I have multiple labels though.
I can't think how I can achieve this for multiple labels, does anyone have any idea how I can do this?
Here is my code so far...
var timer;
$('.label').mouseenter(function(){
clearTimeout(timer);
$('#' + this.id + ' div').slideDown('slow');
});
$('.label').mouseleave(function(){
var temp = $('#' + this.id + ' div');
timer = setTimeout(function() {
temp.stop().slideUp('slow');
}, 2000);
});
Thanks in advance for any help.

You can maintain an array of timers like
var timer = [];
$('.label').mouseenter(function(){
clearTimeout(timer[$(this).index()]);
$('#' + this.id + ' div').slideDown('slow');
});
$('.label').mouseleave(function(){
var temp = $('#' + this.id + ' div');
timer[$(this).index()] = setTimeout(function() {
temp.stop().slideUp('slow');
}, 2000);
});
You can also achieve this with a more clear syntax using .hover like
var timer = [];
$('.label').hover(function(){
clearTimeout(timer[$(this).index()]);
$('#' + this.id + ' div').slideDown('slow');
},function(){
var temp = $('#' + this.id + ' div');
timer[$(this).index()] = setTimeout(function() {
temp.stop().slideUp('slow');
}, 2000);
});

Why dont you use hover :
$('.label').hover(function(){
$('#' + this.id + ' div').slideDown('slow');
},
function(){
$('#' + this.id + ' div').slideUp('slow');
})
This way, when labels are hovered upon, more info will show and when mouse leaves them, they will hide back again.
The first param to hover is for mouse enter while second for mouse leave.
More Info:
http://api.jquery.com/hover/

Instead of using global variable timer you can use jQuery's .data() method like this:
$('.label').hover(function(){
clearTimeout($(this).data('hover_timeout'));
$('#' + this.id + ' div').slideDown('slow');
},function(){
var temp = $('#' + this.id + ' div');
$(this).data('hover_timeout', setTimeout(function() {
temp.stop().slideUp('slow');
}, 2000));
});
