Clicking on an element sets focus but not cursor? - javascript

I have an html page where I set the focus on the first input element on load. I can see that the focus is set because I ask the background of the element to go orange and I can see the orange background. However, the cursor is not shown in the element.
Then when I click on the other input elements, I can see the focus move to them but still no cursor is shown. The cursor only appears when I use the tab key.
Please could someone explain to me why this happens and how I can make this cursor appear without having to use the tab key?
This is for IE8 only. (It's an intranet site)
Code as requested for how I'm setting focus:
$(document).ready(function(){
$('#rachel').focus();
});
EDIT
I didn't think to mention that the problem is happening on a popup window that looks to be implemented like a layer. Is it possible for layers to block the cursor?

hover does not active when trying to see hidden qr code bar?

I am trying to clone a website and here is this website's link
https://shopee.vn/
as you can see in this picture, when I hover the mouse to the line name "tải ứng dụng"
it will show the QR code
picture about problem 1
my problem is, I want to use some extensions like page ruler redux to measure the QR code's size, but it disappear when I move the mouse to another position (I click to the hover at the force element state, but it still disappear).
I think that when I click to the hover at the force element state, it must show the QR code and it will not disappear ?
Could you please give me some way to make it display to measure it?
Thank you very much for your time.
The Chrome/Edge Dev tools have a built-in measurement function, hopefully this gets what you want.
Right-click => Inspect element on the link, expand the div and click on the :after selector
Making sure the inspect element page is in focus (the last thing you clicked on), hover over the link
With only the arrow keys on your keyboard, navigate the element tree (up/down to move up and down, left/right to expand, enter if you want to copy a property, like the image url). As long as you don't click, the element stays up.
find the QR code element node by chrome devtools, as you can see in this picture, the div html which one has a classname be named shopee-drawer__contents
picture about how to find element node name
In chrome devtools console, you can print it out or use document method to measure it.
For instanse document.getElementByClass('shopee-drawer__contents').getBoundingClientRect()
print out width & height

Jquery animation mouse cursor not and style not changed after click

I am using JQuery animation ,I am facing issue on chrome.
As per requirement I need to animate the div on click of a link.
when cursor moved hover link, link should be underlined and cursor should show as pointer but even after clicking on link even after animation if user not moved mouse mouse pointer not get changed and link also shows underlined. if users moves mouse it works fine.

Where on other browsers it works fine.
You can add .hide().show(0) for animate element for compensate Chrome bug.
Please, take a look at feedle.

Focusing input with selected text causes scroll to top

I'm running into this problem on Chrome. When I use jQuery to focus on an HTML input with part of its text selected, my page jumps to the top instead of the element itself. I've created the following jsfiddle as an example:
http://jsfiddle.net/wzs821jg/3/
I've put margins above and below each input, enough to create a scrollbar. If your resolution is taller than mine (I'm on a laptop) and you have no scrollbar, just add more margin until you do.
Add enough text to the second input to cause it to scroll (overflow on the x). You can just add jibberish, such as "asdfkasdkjfhakjsdhfaksdjhfkajshdkfajshdkfajshdkfjah", which should work fine. Once you've gotten enough text, highlight a portion of it. Now there are two methods you can use to cause the page to scroll to top:
Click the button, which has a short jQuery listener that will focus on the second input.
Focus the first input and then press tab to focus the second input
On Chrome Version 41.0.2272.101 (64-bit) on OSX Yosemite, both of those actions should cause the window to jump to top instead of focusing on the second input. I've tried on Safari, and I can't recreate the issue. I've experienced different behaviors depending on where you select the text (outside, inside, or across the overflow) and the method used to focus. Play around with it a bit.
My question is: is this a problem with Chrome or am I doing something wrong?
Edit: I've filed a bug report with Chrome pointing to this question. Unless someone has an answer, I'm just going to assume it's simply a bug within the browser.

Limiting an editable div area by height, simulating onkeyup event in Javascript

I know there are many similar topics but none of them has the solution to my problem so please read my question carefully before sending similar topic links and marking as duplicate question.
I have a content editable DIV object, something similar to TextArea control. My goal is to cancel key press events if content starts scrolling and there must be no flickering.
When i use keyUp event, it's too late to cancel and there is also no methods available to cancel changes. What's done is done at this stage.
When i use keyDown or keyPress events, they are cancelable. But new changes are not yet applied. So, i know which character is pressed etc. but i still don't know how it's going to affect the scrolling size.
Plus, i allow style changes like making the text bold or changing the font size. Since there is;
document.execCommand("undo");
command, i'm able to test these changes and undo if scrolling starts. To test things, i use a cloned div with same content. It works fine. Changes are applied to cloned div (which is visible at the moment for debugging purposes but will be invisible if the method works) and if cloned div has an overflow, changes are canceled.
My problem is at doing the same thing for key presses. It's harder to simulate what happens to editable div content than using document.execCommand for other styling options. What i need is to get the innerHTML result at keyUp stage before keyUp occurs and event is still cancelable like keyDown or keyPress.
To simulate things, i tried getting cursor position and adding pressed characters manually using substring function but content isn't plain text and i had many problems with it. For instance when i press enter, an HTML block <div><br></div> is added for newline character which messed up cursor position. I tried many ways to handle things but it's very open to bugs. So, i decided not to follow this path.
In short my question is;
How can i possibly limit an editable div area by height, not allowing
to overflow or scroll without any flickering, just canceling key press
events? Do i have to simulate something like willKeyUp or is there any
other cross browser way?
Here is jsfiddle link for my sample which works for document.execCommand case (changing font size, weight etc.) but fails at typing letters;
http://jsfiddle.net/7zQD2/
Edit: To clarify my goal at jsfiddle example, after writing 5 lines of text, either when you press enter or type to end of the line, cursor should never reach to the sixth line. Key presses should be canceled and cursor should stay at fifth line with no content changes or flickers.
One solution is to use the cloning setup you already have, but to set the opacity of the first copy to 0 and position it on top of the clone with position: absolute in the css. The first copy won't be visible, but will catch a click directed towards the visible one underneath it. You can change your event to fire on keyup.
Since the transparent div still exists, and still has height, it can measure text height for you without being visible to the user. The visible text then updates to match what is learned with the transparent text, and never reaches the 6th line or flickers.

Webkit Tap Highlight Color Larger than Links

Within a UIWebView in an iOS app I have events firing in javascript when a link is pressed. There is also a grey box that typically appears over links when they are tapped. The -webkit-tap-highlight-color css property.
However, the hit area that activates this grey box is different from the element frame according to javascript. The result is that if I tap a certain distance from links the tap highlight color is activated but the event is not fired as you expect it to when you get this feedback.
Is there any way to correct the frame that activates the highlight color? or perhaps there is an easier way to just disable that and provide similar feedback another way?
