Get back a variety of substitutions

I have a variety of different text strings that I need to swap out on the client side.

For example, let's say I need to replace "Red Apple" with "Orange Orange" and "Sad Cat" with "Happy Dog".

I've been working on enhancing this particular question to handle multiple replacements.

$("#container h3 a").text(function () {
  return $(this).text().replace("Red Apple", "Orange Orange"); 
  return $(this).text().replace("Sad Cat", "Happy Dog");
});

However, I'm running into an issue where only the first replacement is being returned.

I am struggling to figure out how to return more than one replacement. The code snippet above is not achieving the desired outcome.

return {
  ...
}

The reason why this is not considered a duplicate: I am not just trying to replace instances of Apples, but also Cats.

Answer №1

The initial return statement terminates the function, preventing the execution of the second return statement.

However, it is possible to link together multiple replacement operations.

$("#container h3 a").text(function () {
    return $(this).text().replace("Red Apple", "Orange Orange").replace("Sad Cat", "Happy Dog");
});

When your code encounters a return statement, any code following it will not be executed. The purpose of the return statement is to return control to the calling code.

According to MDN:

The return statement stops the function execution and specifies a value to be passed back to the function caller.

To address such situations, there are a few approaches you can take:

You have the option to build up a value and then return that value:

$("#container h3 a").text(function () {

  // Manipulate the return value as needed
  var retVal = $(this).text();
  retVal = retVal.replace("Red Apple", "Orange Orange");
  retVal = retVal.replace("Sad Cat", "Happy Dog");

  return retVal;  // Return the final value
});

It is worth noting that this method is perfectly fine as it is easy to understand and follow.

Alternatively, you can chain the .replace() calls in this scenario. Each call to .replace() generates a new string on which you can call another .replace(). The end result will be returned as the value sent back by the initial return:
```
$("#container h3 a").text(function () {
  return $(this).text().replace("Red Apple", "Orange Orange")
           .replace("Sad Cat", "Happy Dog");
});
```
This approach achieves the same outcome but in a more concise and efficient manner, eliminating the need for a temporary variable.

It is possible to achieve this by using two replace functions within a single return statement.

return $(this).text().replace("Red Apple", "Orange Orange").replace("Sad Cat", "Happy Dog");
