We have a Suitelet page with a sublist, which has a check box field.

And I would like to put the button to do all-check and all-uncheck it.

I wrote the following logic but it didn't work.

function onRequest(context) {
:
(making sublist...)
var sublist = form.addSublist({
        id: "custpage_sublist",
        label: "検索結果",
        type: serverWidget.SublistType.LIST,
});

// The button to uncheck all
form.addButton({
   id: "custpage_chk_box_false",
   label: "全解除",
   functionName: autoCheck(sublist, "F"),
   });
}

(While loop...)
sublist.addField({
            id: "target_check_box",
            type: serverWidget.FieldType.CHECKBOX,
            label: "更新対象",
});



function autoCheck(sublist, flg) {
  const lineCnt = sublist.lineCount;
  for (var l = 0; l < lineCnt; l++) {
   sublist.setSublistValue({
    id: "target_check_box",
    line: l,
    value: flg,
   });
 }
 }
