The creator of this report set up the last column so that clicking it executes a script.

If you open the report (by double-clicking it) and page down almost to the bottom, you will see the following line of code:


This line is looking for a JavaScript function named Email_Script. In this section, you will create this JavaScript function. The function will enable end users to send email to the address they click in this column.

    This command creates a JavaScript library. You will be writing the Email_Script function in this library.

  4. Enter the following code:
    function Email_Script(address)
    location = "mailto:" + address;

    Note: Type this code exactly as shown. JavaScript is case-sensitive.

  5. Close MyScript.
  6. Open Show_Fans_Form.
  7. Tile your screen so you can see both Show_Fans_form and the Explorer. Open the Other folder to display your JavaScripts.
  8. Drag MyScript.JS onto the ShowFan form. You must drop MyScript into an empty area on the form, not on top of a control.
  9. You are prompted to either Embed or Link the Script. Select Embed.
