img form with overlay function

I have a picture, which should open an overlay on click.
The overlay should be closed by a click as well.
I had an almost working version with a button, but the picture was shifted.
I tried a form function and it looks much better, but I only see the overlay flickering before it's disappearing. So the onclick function doesn't work anymore.
function on() {
document.getElementById("overGeld").style.display = "block";
}
function off() {
document.getElementById("overGeld").style.display = "none";
}
css: #overGeld {
display: none;
width: 380px;
height: 350px;
background-color: aliceblue;
position: absolute;
border: none;
margin-left: -50px;
padding: 10px;
line-height: 130%;
}
<div id="spendMö">
<form class="bildbt" onclick="on()">
<input type="image" class="bilder" id="geld" src="hund-geld.jpg">
</form>
<div id="overGeld" onclick="off()">
<a>.....</a>
</div>

input type="image" is a submit button -
you need to use <imgor <button type="button" or a link with a preventDefault
document.getElementById("spendMö").addEventListener("click", function(e) {
let imgStyle = document.getElementById("overGeld").style;
imgStyle.display = imgStyle.display === "block" ? "none" : "block";
})
#overGeld {
display: none;
width: 380px;
height: 350px;
top: 100px;
background-color: aliceblue;
position: absolute;
border: none;
margin-left: -50px;
padding: 10px;
line-height: 130%;
}
<div id="spendMö">
<img class="bilder" id="geld" src="https://previews.123rf.com/images/helga1981/helga19811605/helga1981160500142/56492101-hund-in-den-gl%C3%A4sern-h%C3%A4lt-in-seine-pfoten-eine-menge-geld-isoliert-auf-wei%C3%9Fem-hintergrund.jpg">

Display div after placeholder is removed during form input

I have a div I would like to show when a customer enters into a form. I originally though a z-index solution would fix this but a display/show option seems better.
However, it doesn't seem to work. Can this be shortened or done in a better way?
$(document).ready(function(){
if ($("input#poundprice").text().length > 0) {
$('.pence-sign').show();
//$('.pence-sign').addClass('display:block;');
}
});
Here is the JSFiddle

You need to be checking for when something is actually typed into the box. What you are currently doing only runs once when the page loads.
$(document).ready(function(){
$("#poundprice").on("change keydown paste",function(e) {
$('.pence-sign').show();
});
$("button").click(function(e){
e.preventDefault();
});
});
.pence-sign {
position: absolute;
top: 23%;
left: 30%;
text-transform: lowercase;
font-family: arial;
display: none;
}
input, button {
appearance: none;
border: none;
font-size: inherit;
background: #eee;
border-radius: 3px;
padding: 1rem;
width: 100%;
max-width: 280px;
margin-bottom:1rem;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form style="position:relative">
<div class="poundinput" style="position:relative;">
<p class="pence-sign">pence</p>
<input id="poundprice" name="price" type="currency" placeholder="Enter p value" required="">
</div>
<button type="submit">Submit</button>
</form>

hiding a "No file chosen" tooltip in Javascript

I know there are many question about it, but they don't answer properly.
After readings and looking for, I tried this:
<input id="ext-element-47" class="x-input-file x-input-el" type="file" accept="" style="display:none">
hiding the file-input and then
this.element.down(".x-input-file").dom.click();
this works on Chrome's console but in my JS code it doesn't. It doesn't click.
Anyone knows why? and what can I do for make click?
Notes:
I need to make click because the file element is not visible and so when it clicks it does not show unless I do element.click ().
Here is an example what I'm doing:
document.getElementsByClassName('o-file-field-input')[0].click()
.o-file-field-input {
display: none;
}
.o-big-btn {
background-color: red;
height: 3em;
width: 3em;
}
<div class="x-container x-unsized o-cont-option" data-componentid="ext-container-5" id="ext-container-5">
<div class="x-inner x-align-center x-pack-center x-horizontal x-layout-box" id="ext-element-50">
<div class="x-button x-button-plain open-field-icon o-big-btn x-layout-box-item x-flexed x-stretched" id="ext-OUI_BaseButton-1" data-componentid="ext-OUI_BaseButton-1" tabindex="0" style="-webkit-box-flex: 1;">
<span class="x-button-icon x-shown smf smf-upload-file" id="ext-element-45"></span>
<div class="o-button-bg"></div>
<div class="x-unsized x-field-input x-has-height" id="ext-fileinput-1" data-componentid="ext-fileinput-1" style="height: 38px;">
<input id="ext-element-47" class="x-input-file x-input-el o-file-field-input" type="file" accept="">
<div class="x-field-mask x-hidden-display" id="ext-element-48"></div>
<div class="x-clear-icon" id="ext-element-49">
</div>
</div>
</div>
</div>
</div>
See ya!

Here's what I usually do: Wrap the input inside a <label> element, and then style the element as a button, for example:
.pretty-file {
border: 1px solid #000;
cursor: pointer;
display: inline-block;
padding: 5px 15px;
}
.pretty-file input[type="file"] {
display: none;
}
<label class="pretty-file">
Choose File
<input type="file" />
</label>

This finally works well:
var obElement = document.getElementsByClassName('input-file')[0];
//the title property overrides tooltip's description
obElement.setAttribute('title', ' ');
.flex-style{
display: flex;
}
.input-file{
opacity: 0;
margin-left: -40px;
width: 40px;
height: 45px;
}
.icon{
width: 40px;
height: 45px;
background-color: blueviolet;
}
<div class='flex-style'>
<div class='icon'></div>
<input class='input-file' type='file'>
</div>

How can I Validate forms with jquery?

Thanks to some awesome people on stack overflow i was able to get my classes toggled and got my form slide up and down correctly. I'm having issues validating the form before it becomes submitted. Could someone help me with a step in the right direction? I just want the validation to check that the fields have some text in them before allowing the submit.

<h2>About this page layout:</h2>
<p> The main container (parent) has 'relative' positioning so that the 'login' container can be absolutley positioned with respect to
that main container. Otherwise, it would default to being absolutley positioned with respect to the window. </p>
<p> In order for the login panel to be placed on top of the page we need to use absolute positioning, otherwise,
it would move the rest of the content down as done in the FAQ assignment. Technically, absolute positioning takes that element out of
the normal flow of the document, so that it is on top of the page. The 'ad' is also absolutely positioned to the same main container. </p>

Take a look into jQuery Validate.
This jQuery plugin makes simple clientside form validation easy, whilst still offering plenty of customization options.

I hope you can learn from this. I'll just give you an example with one of your fields and a submit button. Initially the submit button is disabled, then you can use the keypress event to check if 1 or more characters are entered and enable the submit button.
Fiddle: https://jsfiddle.net/stevenng/8w89v3tp/1/
HTML:
<label for="username">Username:</label>
<input type="text" name="username" id="username">
<button class="js-submit">submit</button>
JS:
var $submit = $('.js-submit');
var $username = $('#username');
$submit.attr('disabled', true);
$username.keypress(function() {
if ( $username.val().length > 0 ) {
$submit.attr('disabled', false);
}
});
$submit.on('click', function(){
// do something
});

disable jQuery removing javascript tags

Best all,
I'm trying to debug our CMS (what is mostly AJAX) but jQuery removes all the script tags, what makes me unable to debug the JavaScript, how do I disable this behaviour?
I thought I would find it after a simple Google search but no success :(
Thank you,

console.log("Laten we is kijken: " + inter);
clearInterval(inter);
});
inter = setInterval(function(){
jQuery.getJSON("/googlemonster/backend/status-test",function(json){
setProgressBar(json);
});
},200);
return false;
});
});
function
function setProgressBar(obj){

You are right – it is a feature of jQuery to strip out script tags. You need to use the basic JavaScript methods instead.
See: Can't append <script> element
Scripts will be evaluated first, and then discarded.
http://api.jquery.com/append/

after some research I finnaly could fix the problem thanks to the guys here,
I made a little plugin for jQuery for it, now the script tags are not getting, removed but executed.
(function($){
$.fn.loadDebuggable = function(url){
data = typeof(arguments[1]) == "object"?arguments[1]:{};
success = arguments[2]||typeof(arguments[1]) == "function"?arguments[1]:function(){};
return $.ajax(url,{
"context":this,
"success":[function(data){
var div = document.createElement('DIV');
div.innerHTML = data;
this[0].innerHTML = "";
while (div.firstChild)
{
this[0].appendChild(div.firstChild);
div.removeChild(div.firstChild);
};
},success],
"type":"GET",
"data":data
});
}
})(jQuery);
Thanks,
