Javascript PDF表格单选按钮显示/隐藏

Question

I searched and couldn't find any results pertaining to javascript / PDF form applications so I apologize if there are actual results out there that I may have missed.

I have 5 radio buttons, all sycronized for if one is turned on, rest are turned off. I'm trying to enable, based on which is selected, for which form (Cells) to show on a pdf.

This is currently where I stand. The radio button for this script is set to mouse-up, and when turned on Text2 shows, but when a separate radio button is selected Text2 still shows. Only when I re-selected the first radio button does the Text2 disappear.

I'm looking to show only particular cells based on what radio button is selected, and the rest are hidden.

If someone could help lead me to a small example and I could apply from there. Thank you

if (this.getField("Text2").display == display.hidden)
{
this.getField("Text2").display = display.visible;
}
else
{
    this.getField("Text2").display = display.hidden;
}

edit: grammar update: This is what i'm necessarily trying to accomplish

if (this.SELECTED("Choice4")){
this.getField("Text4").display = display.visible}
else{
this.getField("Text4").display = display.hiddenl}

update2: does not work either

if(document.getElementByI("Choice3").checked){
this.getField("Text4").display = display.visible}
else{
this.getField("Text4").display = display.hidden}

Answer 1

The trick is when toggling a button in a set of radio buttons (or checkboxes behaving as radio buttons) is to first hide all fields which could be shown, and then show the ones matching the selection.

This can be made a lot easier with hierarchical field names. All fields which can be shown or hidden have the same stem in their name, and the second element matches the option, as in

showfield.option1.myfield

with

this.getField("showfield").display = display.hidden

you make all fields being part of the showfield group hidden, and with

this.getField("showfield.option1").display = display.visible

you show all fields in the option1 group within the showfield group.
