Using the OnChange event

The example below is an HTML form that is used with a javascript function to calculate the cursor position in a terminal emulator.

When the row or column value in the form is changed, the function IdentifyScrnLoc is triggered and recalculates the screen position

24 Row x 80 Column
Screen Position Calculator

_ X _

The function call from the form on the webpage delivers two values to the function. The row number and the column number.

<INPUT TYPE = "text" ID = "lblScrnRow" NAME = "row" defaultValue = " 1 " SIZE = 3 MAXLENGTH = 2 OnChange = " IdentifyScrnLoc(row,col)" >
_ X _ <INPUT TYPE = "text" ID = "lblScrnCol" NAME = "col" defaultValue = " 1 " SIZE = 3 MAXLENGTH = 2 OnChange = "IdentifyScrnLoc(row,col)" >
