我想知道如何使用“添加产品”按钮在上一个现有面板(“productOtherPanel”)下面添加一个重复的面板。我希望将新面板插入现有“productOtherPanel”下方和“Add Product”按钮上方。我还希望这个新面板包含与原始“productOtherPanel”相同的下拉列表和文本框。我需要这个面板复制无数次。这可能吗?
function doGet(e) {
var app = UiApp.createApplication();
var productOtherPanel = app.createHorizontalPanel().setId('productOtherPanel');
var productPanel = app.createVerticalPanel().setId('productPanel');
var productList = app.createListBox().setName("productList").setId('productList');
productList.addItem("8:1 Compressed Blocks");
productList.addItem("8:1 Compressed Briquettes");
var pricePerTonPanel = app.createVerticalPanel().setId('pricePerTonPanel');
var pricePerTonTextBox = app.createTextBox().setId("pricePerTonTextBox").setName("pricePerTonTextBox")
.setText("$0.00");
var buttonPanel = app.createVerticalPanel().setId('buttonPanel');
var button = app.createButton("Add Product");
app.add(productOtherPanel);
productOtherPanel.add(productPanel);
productPanel.add(productList);
productOtherPanel.add(pricePerTonPanel);
pricePerTonPanel.add(pricePerTonTextBox);
app.add(buttonPanel);
buttonPanel.add(button);
return app;
}

尝试查看此代码是否符合您的要求:
function doGet(e) {
var app = UiApp.createApplication();
var productOtherPanel = app.createVerticalPanel().setId('productOtherPanel');
var productPanel = app.createHorizontalPanel().setId('productPanel');
// Product list dropdown
var productList = app.createListBox().setName("productList").setId('productList');
productList.addItem("8:1 Compressed Blocks");
productList.addItem("8:1 Compressed Briquettes");
// Product Price Textbox
var pricePerTonTextBox = app.createTextBox().setId("pricePerTonTextBox").setName("pricePerTonTextBox").setText("$0.00");
productPanel.add(productList);
productPanel.add(pricePerTonTextBox);
var buttonPanel = app.createVerticalPanel().setId('buttonPanel');
var button = app.createButton("Add Product");
button.addClickHandler(app.createServerHandler("addProductHandler").addCallbackElement(productOtherPanel));
app.add(productOtherPanel);
productOtherPanel.add(productPanel);
app.add(buttonPanel);
buttonPanel.add(button);
return app;
}
function addProductHandler(e) {
var app = UiApp.getActiveApplication();
var productPanel = app.createHorizontalPanel().setId('productPanel');
// Product list dropdown
var productList = app.createListBox().setName("productList").setId('productList');
productList.addItem("8:1 Compressed Blocks");
productList.addItem("8:1 Compressed Briquettes");
// Product Price Textbox
var pricePerTonTextBox = app.createTextBox().setId("pricePerTonTextBox").setName("pricePerTonTextBox").setText("$0.00");
productPanel.add(productList);
productPanel.add(pricePerTonTextBox);
var panel = app.getElementById("productOtherPanel");
panel.add(productPanel);
return app;
}
