How to remove extra space in an iframe generated DOM?

I am displaying an iframe on my web page. However there is extra space like in the generated DOM. How can I remove it? I used jQuery like this. Didn't work. Thanks.
jQuery
jQuery(document).ready(function () {
let $iframe = $("iframe[name=previewIframe]");
$iframe.on('load',function() {
$iframe.contents().find("body #gwd-ad").text().replace(/\s+/g, " ").trim();
});
});
HTML

Try this:
$iframe.on('load',function() {
var $ad = $iframe.contents().find("#gwd-ad");
$ad.html($ad.find("a").html())
});

How to automatically click a href link when the page loads?

I'm trying to automatically click a href link when the page loads.
<div class="loadmore" kind="rb">
تحميل المزيد...
</div>
The link is supposed to load more comments when you click it.
I tried this:
window.onload = function() {
autoloadmore()
};
function autoloadmore() {
var loadmoreClass = document.getElementsByClassName("loadmore")[0];
var loadmoreChild = loadmoreClass.getElementsByTagName("a");
if(loadmoreClass){
loadmoreChild[0].click();
}
}
but it doesn't seem to work. The problem seems to be with click(), because when I use other codes such as .style.color, they work.
I'm using Blogger by the way.
This's a sample blog:
http://blog-sample-001.blogspot.com/2018/09/title.html
(go to تحميل المزيد...)
ps: I can't change the div.

Assign some ID to تحميل المزيد... . For example, clickAfterPageLoad or whatever you want, and then try this...
$(document).ready(function() {
$("#clickAfterPageLoad").trigger('click');
});
or if you cant't change div, you can do like this:
$(document).ready(function() {
$(".loadmore a").trigger('click');
});

Unable to find click event

Here is my JQuery Code:
$(function () {
$('[id*=clickbtn]').click(function () {
var url = "WindowPages/EditorControl.aspx?controlName=" + this.name;
oWnd.setUrl(url);
oWnd.show();
});
});
Now the problem is, i have 4 to 5 buttons whose id contains 'clickbtn' when i click the any one of them for first time it works well. But it does not works for second click, any help why is this happening?
[EDIT]:
I tried putting the JQuery on page and it worked.. But wnt to know why it does not work on when i put the same on .JS file?

Yes, the result of your event handlers depends very much on the content of your event handlers. If you'd like to share with us the rest of the code we might be able to help. For now the answer is: working as intended
jsFiddle
If your clicks only work on the first try, then I can assure you that it is only the missing code which is to blame. Provide the contents of oWnd.setUrl and oWnd.show and we might be able to help.

Your wildcard selector is wrong. It should be
$("[id$=clickbtn]")

Try this:
$('input[ID*="Button"]')
OR
First set class="btn" to all buttons you want to do this action then
$(function() {
$('.btn').click(function() {
var url = "WindowPages/EditorControl.aspx?controlName=" + this.name;
oWnd.setUrl(url);
oWnd.show();
});
});

Writing javascript with jquery and using a variable

As a javascript newbie, I am struggling to use a script with a variable that runs a bit of JQuery (and also struggling to use the right language here, I'm sure!)
The action I want to happen is to change the CSS class of a specific div, e.g. #det90, for which I have the following code (I have used the same on a $(window).load(function() and it works on a different set of divs):
$("#MYDIVIDHERE").switchClass("sdeth","sdet",50);
So I wrote the following:
<script type="text/javascript">
$(function revealCode(divID) {
$("#divID").switchClass("sdeth","sdet",50);
})
</script>
and called it from an anchor with:
onClick="revealCode('det90');"
I think the problem is that I don't know how to write the script and pass the variable in the brackets (divID) to the next line (where I've got "#divID"). Any help or pointers to tutorials gratefully received!
Solution
Thanks to all, but particularly to Caleb. I've scrapped the general function and the onClick, added an ID to the anchor and inserted the following for that anchor (and then repeated that for each anchor/div combination I want to use it on ... and it works :D
$("#linkID").click(function() {
$("#divID").switchClass("sdeth","sdet",50);
});

Change your code to: onClick="revealCode('#det90');"
$(function revealCode(selector) {
$(selector).switchClass("sdeth","sdet",50);
})
jQuery is powered by "selectors" -- similar to CSS syntax.

Don't quote your variable name. Just quote the "#" prefix.
<script type="text/javascript">
$(function revealCode(divID) {
$("#" + divID).switchClass("sdeth","sdet",50);
})
</script>

Change to:
<script type="text/javascript">
function revealCode(divID) {
$("#" + divID).switchClass("sdeth","sdet",50);
}
</script>
You don't need $() around the function
$("#divID") will look for an element with the ID divID, and not what was specified in your function parameter

This won't work. revealCode is local to that scope and not known outside. Also, you're not using the argument you've passed into your handler.
If you're using jQuery, use it to bind to the handler as well like this:
jQuery(document).ready(function() {
function revealCode(divID) {
$("#" + divID).switchClass("sdeth","sdet",50);
}
jQuery("#divID").click(function() {
revealCode('det90');
});
});

Move your onclick event handler attachment into javascript code. You should try not to mix your functional code with your html.
Anonymous version:
$('#myDiv').click(function () {
$(this).switchClass("sdeth","sdet",50);
});
Normal version:
var myFunction = function (element) {
$(element).switchClass("sdeth","sdet",50);
};
$('#myDiv').click(myFunction, {element: this});

Any ideas as to why this jQuery does not work?

I have an HTML page where a click event is captured and hides #testContent. I put the HTML and Javascript in a jsFiddle here: http://jsfiddle.net/chromedude/VSXY7/1/ . For some reason in the actual page the .click() does not work, but in the jsFiddle works. Does anybody have a clue why this would be?
I have ensured that the jQuery and Javascript file were both correctly attached and show up in the Webkit Inspect and Firebug. I am not getting console errors either. It's quite confusing.
UPDATE:
You can check out the actual page here: http://blankit.co.cc/test/77/

It looks like your javascript is not loaded correctly.
<script type="text/javascript" src="../../includes/jquery.js"></script><script type="text/javascript" src="../../includes/navbar.js"></script><script type="text/javasript" src="../../includes/study.js"></script>
You can put some alert() function inside your javascript file to make sure it is loaded correctly.

Your script tag has a typo in the type change it to text/javascript you are missing a letter.
Change study.js from
$(function(){
console.log('hello');
alert('hello');
/*var testContent = $('#testContent').val();
var contentArray = testContent.split(" ");
$('#studyTestLink').click(function() {
$('#testContent').hide();
alert('hello');
});*/
});
to
$(function(){
$('#studyTestLink').click(function() {
var testContent = $('#testContent').val();
var contentArray = testContent.split(" ");
$('#testContent').hide();
alert('hello');
});
});

I added your code to a page (using jquery 1.5.2) and it works fine. Don't you have any other code that could be breaking it?
