Replacing text

In this recipe, you will learn how to replace portions of text based on a search and match schema. We will use the replace command to accomplish this task.

How to do it...

Replacing sections of text can be a powerful part of a mobile app. Follow this recipe's steps to perform a global find-and-replace operation:

  1. Create a new main stack in LiveCode.

  2. Drag a new button to the card.

  3. Name the new button replaceText.

  4. Add the following code to the button:

    on mouseUp
  local tempText
  put "EMP001, EMP002, EMP003, EMP004, EMP005" into tempText
  replace "EMP" with "EMP#:" in tempText
  answer tempText
end mouseUp

How it works...

We created a local variable (tempText) to hold our original text. Next, we used the replace command to change all occurrences of EMP to EMP#:. We then used the answer command to display the results.
