I would like to have a help function installed. I want the user to be able to press F2 in any text box on an HTML form and have a pop up window appear with various text pertaining to that textbox.

In my test textbox, I have the following code:

where name is the name of the text box and the JavaScript function is named help_function()

In the JavaScript file, I have the following code:
Expand|Select|Wrap|Line Numbers
  1. var unicode = e.keyCode? e.keyCode : e.charCode
  2. if(unicode == 113)
  3. {
  4. //113 is the F2 key
  5.      if(name=="sku")
  6.      {
  7.         . . . code for help goes here . . . 
  8.       }
  9. }
There are two problems:
1. I would like to replace the second if statement in the JavaScript code with a select statement. I probably have a typo with this logic and this is not that important since I only have 5 textboxes.
2. When the user types in one character in this test textbox, the entire field is selected and only one character can be entered. For what it's worth, I do have the following code in my HTML document:
<body onLoad = "document.form1.sku.focus()">

The sku textbox is my test textbox.

If you need any additional information, please let me know. I am not a beginner but not an expert at JavaScript so you may have to explain some things in depth.

Thanks for your time.

1. I think you mean a switch statement.

2. Check the length of the input if you want to avoid the whole field being selected after only one letter before calling
