Introduction
Calling a function in Javascript is a fundamental part of the language and is essential for writing code. This tutorial will explain how to call a function in Javascript, including how to pass arguments to the function and how to return a value from the function. It will also discuss some of the common errors that can occur when calling a function. Finally, it will provide some examples of how to call a function in Javascript.
Solution
To call a function in JavaScript, you can use the following syntax:
functionName(parameters);
For example, if you have a function called “myFunction” that takes two parameters, you can call it like this:
myFunction(param1, param2);
The problem here is not how you call yea
, it is everything around it.
This would be fine:
append( some_string + yea() + some_string );
… but where you should have strings (which could be string literals or variables or any other JavaScript expression), you have raw HTML, which isn’t allowed.
You seem to have missed the '
off from the start of the first string, and the other '
from the end of the second string, and inserted a raw new line in the middle of both (which is forbidden).
$(wrapper).append(
'<div class="form-group"><select name="from_year[]" class ="form-control"> ' + yea() + ' </select></div>'
);

Calling a function in JavaScript is a relatively straightforward process. The basic syntax for calling a function is to simply write the function’s name followed by parentheses, like this:
myFunction();
If the function takes arguments, you can pass them to the function by placing them inside the parentheses, separated by commas. For example:
myFunction(arg1, arg2);
If the function returns a value, you can capture the return value by assigning it to a variable. For example:
var result = myFunction(arg1, arg2);
It’s important to note that the parentheses are required even if the function takes no arguments. If you forget to include the parentheses, the function will not be called.
Finally, it’s worth mentioning that you can also call a function using the Function.prototype.call()
or Function.prototype.apply()
methods. These methods allow you to pass arguments to the function and also set the this
keyword inside the function. For more information, see the MDN documentation on Function.prototype.call() and MDN documentation on Function.prototype.apply().
