Javascript – Change JS code in Inspect Element Editor

domhtmljavascriptjquery

When I make some changes in html content using Chrome's Inspect Element editor the changes are immediately reflected. But when I make a change in Javascript code then the changes are not reflected.

Suppose on click of a button I say, alert "John is a Good boy" and When I change it to "John is a bad boy" using Inspect element(JS code) then the changes are not reflected on button click and the old text "John is a Good boy" gets displayed.

So when a page gets loaded, its not possible to edit the JS code and see the changes ? Why is it so ?

In my experience, the edits I've made to Javascript files have been reflected immediately. However, an easy fix you might try is as follows:

Insert a breakpoint on the line you want to edit
Reload the page (breakpoints will persist)
Edit that line when the breakpoint is hit
Click Continue on the debugger

Html – How to horizontally center an element

You can apply this CSS to the inner <div>:

#inner {
  width: 50%;
  margin: 0 auto;
}

Of course, you don't have to set the width to 50%. Any width less than the containing <div> will work. The margin: 0 auto is what does the actual centering.

If you are targeting Internet Explorer 8 (and later), it might be better to have this instead:

#inner {
  display: table;
  margin: 0 auto;
}

It will make the inner element center horizontally and it works without setting a specific width.

Working example here:

#inner {
  display: table;
  margin: 0 auto;
  border: 1px solid black;
}

#outer {
  border: 1px solid red;
  width:100%
}

<div id="outer">
  <div id="inner">Foo foo</div>
</div>

EDIT

With flexbox it is very easy to style the div horizontally and vertically centered.

#inner {  
  border: 1px solid black;
}

#outer {
  border: 1px solid red;
  width:100%;
  display: flex;
  justify-content: center;
}

<div id="outer">
  <div id="inner">Foo foo</div>
</div>

To align the div vertically centered, use the property align-items: center.

Javascript – How to detect a click outside an element

Note: Using stopPropagation is something that should be avoided as it breaks normal event flow in the DOM. See this CSS Tricks article for more information. Consider using this method instead.

Attach a click event to the document body which closes the window. Attach a separate click event to the container which stops propagation to the document body.

$(window).click(function() {
  //Hide the menus if visible
});

$('#menucontainer').click(function(event){
  event.stopPropagation();
});
