ultrasound0000 Posted February 19, 2009 Share Posted February 19, 2009 have a radio button with three options, let's say, A, B, C. And several drop-down fields (selects), lets say, 1, 2, 3, 4 . . . I want to change the values in select fields based on the radio button choices. So if user selects A on the radio button, then drop-down 1 has one set of values, if user selects option B on the radio button, then drop-down 1 has another set of values, and so on ... I can use JS or PHP to accomplish this. Also, all select values are hard-coded (no db or file). An important thing to note is that on-change the selects call a JS function that does some computations and displays the results on screen right away. So, each time a radio button value changes, it should change the selects' values and also update the computations. Any help is greatly appreciated!

JonnoTheDev Posted February 19, 2009 Share Posted February 19, 2009 Write a Javascript function that populates the select list using DOM via an onChange event handler on each radio button.
