I want to calculate the pressure of a hydrostatic fluid column with p(psi)=0.052*density(lb/gal)*depth(ft) I have created a form with fields to enter the input, but I need somehow to pass the information entered to the JS calculation to display the result. How can you pass an entered field value to JS caluclation and show the result into another field.

OK, I started off with a simpler example, just an addition of 2 numbers. I know this should be pretty close to the correct setup by looking at other Javascript examples, but it just does not work jet. Any suggestions Thanks Jeroen \startJSpreamble {Calculate} used now function Calculate () { v = getField("textC") ; v.value = 0 ; v.value += AFMakeNumber(getField("textA").value) ; v.value += AFMakeNumber(getField("textB").value) } \stopJSpreamble \starttext \setupfield [lineABC] [label,frame,horizontal] [frame=off] [height=18pt,width=15em,align=middle,frame=off] [height=18pt,width=20em,align=right,style=\tfx,,frame=on] \definefield[textA] [line] [lineABC] [] [] \definefield[textB] [line] [lineABC] [] [] \definefield[textC] [line] [lineABC] [] [] \startJScode{Calculate} AFSimple_Calculate("SUM", new Array ("textA", "textB")); \stopJScode Calculate the addition: A + B = C \\ \field[textA][Please enter A] \\ \field[textB][Please enter B] \\ \goto{Calculate the Result}[JS(Calculate)] \\ \field[textC][The Calculation Result C = ] \stoptext From: jeroen.muskee@hotmail.com To: ntg-context@ntg.nl Date: Sat, 21 Nov 2009 14:19:03 +0100 Subject: [NTG-context] Fields and JS Calculations I want to calculate the pressure of a hydrostatic fluid column with p(psi)=0.052*density(lb/gal)*depth(ft) I have created a form with fields to enter the input, but I need somehow to pass the information entered to the JS calculation to display the result.
