javascript - PDF Acro javascript 对话框问题

Question

我正在创建自定义 PDF 对话框，但在获取输入的值时遇到问题。我检查了代码，找不到问题所在。当我按接受并显示输入到 field1 中的值时，它显示“未定义”。任何有关错误所在的指示都会有所帮助，提前致谢。

 [// Dialog Definition]
var oDlg = {
 field1: "",
 field2: "",
 field3: "",
 field4: "",
// [* initialize: Method that runs when the dialog is created*]
 initialize: function(dialog) {
 var dlgInit = {
 "firstLine":this.field1,
 "secondLine":this.field2,
 "thirdLine":this.field3,
 "forthLine":this.field4,};
 dialog.load(dlgInit);
 },
// [* commit: Method called when OK button is selected*]
 commit: function(dialog) {
  var data = dialog.store();
  this.field1 = data["firstLine"];
  this.field2 = data["secondLine"];
  this.field3 = data["thirdLine"];
  this.field4 = data["forthLine"];
 },
// [* description: Actual dialog box fields *]
 description: {
  name: "Test Dialog",
  elements: [ {
   type: "view",
   elements: [ {
    name: "Additional Information",
    type: "static_text",
   },
   {
    name: "(For Further Credit, Reference of other Information)",
    type: "static_text",
   },
   {
    item_id: "firstLine",
    type: "edit_text",
    char_width: 35
   },
   {
    item_id: "secondLine",
    type: "edit_text",
    char_width: 35
   },
   {
    item_id: "thirdLine",
    type: "edit_text",
    char_width: 35
   },
   {
    item_id: "forthLine",
    type: "edit_text",
    char_width: 35
   },

   {
    type: "ok_cancel",
   },
  ] },
 ] }
};

[// Dialog Activation]
if( "ok" == app.execDialog(oDlg)) { // [* ok_cancel button was pressed with ok *]
app.alert("The value is: "+oDlg.field1,3);
}

第 99 页 - item_id 描述:

"An ItemID for this dialog, which is a unique 4- character string."

你的问题现在有点老了，但也许我的回答可以帮助其他人。 ;)
