Jquery Else If Code Will Execute

If the expression in small brackets is true, it will execute the block inside the if statement, otherwise, the else block of code will execute.

If the given number is 3, it will be evaluated as true in the if statement, so the statement inside the if statement will execute.

If it is some other number the PHP else statement part will execute.

As you open the demo page, an HTML dropdown will be displayed.

If some other color is chosen from the dropdown, it will keep on checking the elseif statements.

After entering the email and pressing the submit button, the PHP script will check the format of email address and displays the message accordingly.

For that, a simple numeric array is created with five elements.

After that, a foreach loop is used to display those array elements.

In that case, you should perform some action if the first condition is true and then check the second condition by using another if.else inside the first if statement.

This will start nested if where you can check another condition.

There you can use elseif or else that will relate to the first if statement.

You have to give an expression in the if statement which is evaluated.

If it returns as true, it will perform the given actions otherwise, it will move to the next elseif statement (if provided).

If all conditions are false, the else part will execute and after that control will move to the next line of code outside of the if statement.
