我想使用从 Google 电子表格读取 URL 的 createImage() 创建图像数组。我想忽略 Range 中的空单元格值，并且还能够读取 URL 相邻列上的值。示例：URL、名称、属性。这是我到目前为止所拥有的，但无法在 URL 范围内获取多个值以加载到不同的图像空间中。

function doGet(e) {
var app= UiApp.createApplication().setTitle('Not Here')  
var abspanel= app.createAbsolutePanel();//.setHeight('100%').setWidth('100%');
var stackpanel=app.createStackPanel();
var grid = app.createGrid(8,8);

var titleLabel= app.createLabel('Not Here');
titleLabel.setStyleAttribute("text-align", "center");
titleLabel.setStyleAttribute("font-size", "135%");
titleLabel.setStyleAttribute("font-weight", "bold");
var insertlabel= app.createLabel('Which Schedule? (Insert Document Key)');
var inserttxtbox=app.createTextBox().setId('txtbox').setName('ttbox').setMaxLength(44);
var loadbtn= app.createButton('Load Pictures').setId('loadbtn');
var resetbtn= app.createButton('Refresh').setId('rbtn').setVisible(false);
var daylabel= app.createLabel('Select Day');
var mon= "P - Mon"
var tues= "P - Tues"
var wed= "P - Wed"
var thurs= "P - Thurs"
var fri= "P - Fri"
var dayListBox= app.createListBox().setWidth('140px').setId('day').setName ('sday')
dayListBox.addItem(mon);
dayListBox.addItem(tues);
dayListBox.addItem(wed);
dayListBox.addItem(thurs);
dayListBox.addItem(fri); 

var image1= app.createImage().setPixelSize(250,250).setId('image1').setVisible(false);
var image2=app.createImage().setPixelSize(250,250).setId('image2').setVisible(false);
var image3=app.createImage().setPixelSize(250,250).setId('image3').setVisible(false);
var image4=app.createImage().setPixelSize(250,250).setId('image4').setVisible(false);
var image5=app.createImage().setPixelSize(250,250).setId('image5').setVisible(false);
var image6=app.createImage().setPixelSize(250,250).setId('image6').setVisible(false);

var loadhandler=app.createServerHandler('loadPics');
loadhandler.addCallbackElement(stackpanel);
loadbtn.addClickHandler(loadhandler);

grid
.setWidget(1,0,insertlabel)
.setWidget(1,1,inserttxtbox)
.setWidget(2,0, daylabel)
.setWidget(2,1, dayListBox)
.setWidget(3,1, loadbtn)
.setWidget(3,2,resetbtn)
.setWidget(4,2,spinner)
.setWidget(5,1, image1)
.setWidget(5,2, image2)
.setWidget(5,3, image3)
.setWidget(6,1, image4)
.setWidget(6,2, image5)
.setWidget(6,3, image6);
abspanel.add(titleLabel);
stackpanel.add(grid);
app.add(abspanel);
app.add(stackpanel);

return app;
}


function loadPics(e){
var app= UiApp.getActiveApplication();
var ss= SpreadsheetApp.openById(e.parameter.ttbox);
var list=ss.getSheetByName(e.parameter.sday);
var row= list.getLastRow()-1;
var values2= list.getRange(2,47,1,1);
var values3= list.getRange(2,48,1,1);
var values4=list.getRange(row,49,1,1).getValues();
var image1=app.getElementById('image1').setVisible(true);
var image2=app.getElementById('image2').setVisible(true);
values4 = values4.split(',');

for(var i=0;i<values4.length;i++){
if (values4[i][0] != '')
image1.setUrl(values4[i]);

}

values4=values4.split(',');
for(var i=0;i<values4.length;i++){
if (values4[i][0] != '')
image2.setUrl(values4[i]);

}

return app;  
}

此版本根据需要加载所有图像。您需要调整电子表格访问权限以适合您 - 查看嵌入的评论。

图像被创建为一个数组，以便它们可以在循环中填充并添加到网格中。图像 ID 同样是动态创建的，因此loadPics()可以遵循类似的模式。包括将“名称”列中的值添加为图像标题的示例。

编辑/添加奖励：工作微调器，并支持带有图片的名称和属性。

maxImgs = 6;      // Number of images in grid
colUrl = 0;       // Column containing URL
colName = 1;      // Column containing Name
colAttr = 2;      // Column containing Attributes

function doGet(e) {
  var app = UiApp.createApplication().setTitle('Not Here');
  var abspanel = app.createAbsolutePanel(); //.setHeight('100%').setWidth('100%');
  var stackpanel = app.createStackPanel();
  var grid = app.createGrid(8, 8);

  var titleLabel = app.createLabel('Not Here');
  titleLabel.setStyleAttribute("text-align", "center");
  titleLabel.setStyleAttribute("font-size", "135%");
  titleLabel.setStyleAttribute("font-weight", "bold");
  var insertlabel = app.createLabel('Which Schedule? (Insert Document Key)');
  var inserttxtbox = app.createTextBox().setId('txtbox').setName('ttbox').setMaxLength(44);
  var loadbtn = app.createButton('Load Pictures').setId('loadbtn');
