Since the variable x is declared outside of the function, its value never gets updated and it only contains a copy of what the page content was when the page first loaded.
If you declare the variable inside of the function, it will make a copy of the page's content at the time that the function was called.

This line of code is outside of the loop:
console.log("Target = " + Target[i]);For that reason, The variable
idoes not yet have a value and the result is undefined.if (i.hasAttribute("target")) {The above line is incorrect. The variable
iis just a number between 0 and the number of links, so it doesn't have ahasAttributemethod.You should be calling
hasAttributeon the elementTarget[i]I anticipate further questions about these explanations, so I'll just write functioning code below:
<script> function ATargetHtml() { // Declare Target inside the function to guarantee that the list of links is up to date let Target = document.getElementsByTagName('A'); console.log(" let Target = document.getElementsByTagName('A');") for (var i = 0; i < Target.length; i++) { // Show the current target element in the console console.log("Target = ", Target[i]); // Replaced "i" with "Target[i]" if (Target[i].hasAttribute("target")) { Target[i].setAttribute("target", "_self"); } } } </script>

<?=is equivalent to an echo statement. You should remove the = sign.-

It means that the path is wrong.
I don't know how your filesystem is structured, so I can only guess what the path really should look like.
Maybe this will work:
<img src="images/1.jpg">
Starting a path with a "/" makes the path be relative to the root of the website, not the current folder.

No, aside from the extra ">" mistake, there's no difference between those two.
-
I think the difference will become apparent once multiple instances are created. Try it out and see what happens.
public class PrivateStatic { private static int x =2; private int y=6; public PrivateStatic (int newX, int newY){ x = newX; y = newY; } public PrivateStatic (){} public void print(){ System.out.println(x); System.out.println(y); System.out.println("---"); } public static void main(String[] args){ PrivateStatic obj1 = new PrivateStatic(10,40); PrivateStatic obj2 = new PrivateStatic(11,41); PrivateStatic obj3 = new PrivateStatic(12,42); obj1.print(); obj2.print(); obj3.print(); } }

Java does not permit extending multiple classes. If you want the functionality of multiple classes, it's best to make instances of those classes as properties of your object and then use properties and methods of those instances.
class C { public A a; public B b; } -
Because it's an array, you have to access it's elements using square brackets and an index:
$own_pools = $_GET['own_pools'][0];$own_pools = (int)$_GET['own_pools'][0];Each of your fields will need a different index in the brackets [1], [2], [3] and so on.

Pitch control is not one of the default controls of the <audio> element, so any code which can do it will be complicated.
The Web Audio API is a powerful tool for generating and manipulating audio signals, but it is complicated. I can't just give you code to use because it would take a few hours of my time. The BiquadFilterNode should be able to alter the pitch of a signal passing through it.

You can use element.offsetWidth to get the width of an element in plain Javascript.

There doesn't seem to be a way to avoid it.
I found a discussion about it on StackExchange: https://superuser.com/questions/456700/how-do-i-print-with-the-screen-stylesheet

There is no element with
class="active"in the HTML, so no element will have that style.If you want the the link which corresponds to the page in the iframe to be highlighted, then you will need to have a Javascript program update the links when they're clicked.
-
Something like $("img.sample").parent().parent() should work.

CSS only selects downwards and forwards so that the rendering engine only needs to do a single pass through the HTML document.
What you have to do is find the closest ancestor with a class or ID and reach the div through a series of child and element selectors. The resulting selector might look something like this:
.something > section:nth-child(2) > div:nth-child(4) -
Because of collapsing margins, the default margins on the <h1> tag are extending out of its container. If you set the margin of the <h1> to zero it will fix that.
For testing CSS, you should be using the developer tools in your browser, usually available by pressing the F12 key on the keyboard. It will show you all the elements and which styles are affecting them. It will visually display the padding margins and borders.
In CSS, decimal numbers use the point "." instead of a comma ",". It should be
flex-grow: 2.5;-

Not the navbar. The links. This width property has to be removed:
@media screen and (max-width:400px) {
.topnav a {
float: none;
width:100%;
text-align: center;}}-

That's because the links are wider than the container. You have set the width to 100%, then added 16px if padding to the left and another 16px of padding to the right. The result is that the link is exceeding the width of the container by 32 pixels.
This can be fixed by removing width:100%; from the stylesheet. It's not needed because block elements automatically grow to fit their container.
The last link in the list is going to have a problem because you have set its value to float:right in the HTML in a style attribute, so the media query can't override it. You have to move that CSS rule out of the HTML and into the stylesheet.

The media query needs to be fixed. You have "screen" and "and" mixed up.
Here is how it should be written:
@media screen and (max-width:400px) { -
You'll have to make your layout with flexboxes.
The CSS tutorial has four pages dedicated to flexbox, here is the first one: https://www.w3schools.com/css/css3_flexbox.asp

Remove the height and max-height rules from the columns. The height rules limit how tall the background color will be.
-
max-width would be the proper replacement. If you set min-width you will still have the problem that the element is not allowed to be smaller than 300px and then doesn't fit in the screen.
-
The problem in that screenshot is that you've set the width of those options to 300px, so it is not permitted to get any smaller.
Delete this from your stylesheet:
.charitable-donation-form .donation-amounts .donation-amount {
height: 150px;
width: 300px;
color: #000000;;
border: 0;
background-color: #ababab;
border-radius: 99px;
padding: 2px;
text-align: center;
margin: 6px;
}And also this:
ul.donation-amounts {
width: 300px;

It casts the value of the CustomerName to a boolean 0 or 1 and then inverts that value using NOT. Strings are all equivalent to 0, so the opposite of that is 1.

Set the left and right margins of the element to "auto"
Your element doesn't have any classes or identifiable attributes, so a selector for it is difficult to find.
This might work:
.entry-content > h1 + div { margin-left: auto; margin-right: auto; }

You're copying the entire document into the div, which includes a copy of the div itself. Two divs means two green borders stacked on top of each other.
