Acrobat 中的 Javascript - 无法将值传递出对话框

Question

我在使用 Adob​​e Acrobat 中的自定义对话框时遇到了困难。

我的目标是在您单击顶部工具栏中的按钮时出现一个对话框。该对话框将包含一个可编辑的文本字段和一个 list_box。输入文本后，从列表框中进行选择，然后单击确定，这些值将传递到 PDF 文档上的文本字段。现在我将它们的值返回到控制台。

每次我尝试运行代码时，两个变量（一个用于文本字段条目，一个用于列表框选择）都返回未定义。我对 Acrobat 中的 javascript 非常陌生，所以这个项目就像一个由来自互联网的不同代码 sn-ps 组成的科学怪人一样慢慢地走到了一起，哈哈。

任何见解将不胜感激！

                }
            ]
        }
    }

if( "ok" == app.execDialog(timeDialog)) { 
    var today = new Date();
    var time = today.getHours() + "." + today.getMinutes() + "." + today.getSeconds();
    var TEMP_FIELD_NAME = timeDialog.timeEntry
    var textValue = timeDialog.techEntry;
    console.println(TEMP_FIELD_NAME); 
    console.println(textValue); 
}

谢谢！

看看我为你写的新提交函数。列表项存储为列表，其中具有正索引值的项是选定项。然后您可以访问选定的值。

var timeDialog = {
    initialize: function (dialog) { this.loadDefaults(dialog); },
    commit: function (dialog) {
        this.timeEntry = dialog.store()["tetb"];
        var items = dialog.store()["tnlb"]
        for (var item in items) {
            if (items[item] > 0) {
                this.techEntry = item;
                break;
            }
        }
    },
    loadDefaults: function (dialog) {
        dialog.load({
            "tnlb":
            {
                "Jimmy John": +2,
                "Papa John": +1,
                "Great Gatsby": +0
            }
        })
    },
