问题
I have a google sheet, I want to prompt a user to select ranges to get information from, store that into an array, and then create a chart in an html popup. I have read a bit about the google.script.run functionality, and understand that without the withSuccessHandler(HTMLFunction).FunctionToCall() syntax at the end, the HTML script moves onto the next line. I have a .gs file below, and an .html file, and I was able to get the graph to work when I just entered a static array in my .gs function. However, I seem to be struggling with how to return focus to the editor to get a range, and then to bring the HTML dialog box with the chart back up and get the right data to the function that plots the chart. I saw here that I could use the google.script.host to call the editor.focus() function so the user can now select cells, but I can't seem to get the focus back to the HTML popup without calling the HTML file all over again. Here is my .gs function:
function RetrieveData(){
var ss = SpreadsheetApp.getActive();
var sheets = ss.getSheets();
var s = sheets[1];
var UI = SpreadsheetApp.getUi();
var response = UI.prompt("Please enter the first cell in the category").getResponseText();
var ir = s.getRange(response);
var n= 0;
var stored = [];
stored.push(["Income Category", "Frequency"]);
while (ir.getValue()!= "") {
n = n +1;
ir = ir.offset(1, 0);
}
ir = ir.offset(-n,0)
for(i =0; i<n;i++) {
stored.push([ir.getValue(),ir.offset(n+2,0).getValue()]);
ir = ir.offset(1, 0);
}
return stored;
}
Here is my html that is within the body (Stack Overflow is a little strict, so I am not going to go through the trouble of showing all the HTML; this is just within the body and it is what is communicating with the .gs file):
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(getdata);
function getdata() {
google.script.run.withSuccessHandler(drawChart).RetrieveData();
google.script.host.editor.focus();
}
function drawChart(stored) {
//This apparently shows a log of the object
//console.log(stored);
var data = new google.visualization.arrayToDataTable(stored);
console.log(data);
var options = {'title':'Income',
'width':400,
'height':300,
'is3d':true};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
google.script.run.withSuccessHandler(drawChart).RetrieveData();
}
One last thing I tried was to call the SpreadsheetApp.getUi().showModalDialog(html, "Title") function one more time, but without calling the html file all over again, and creating an endless loop, I don't seem to have a way to do that. Any idea how to accomplish this?

Here's a simple example of picking a range with a modeless dialog. With just a few extra features thrown in for good measure.
Code.gs:
function selRange()//run this to get everything started. A dialog will be displayed that instructs you to select a range.
{
var output=HtmlService.createHtmlOutputFromFile('pickRange').setWidth(300).setHeight(200).setTitle('Select A Range');
SpreadsheetApp.getUi().showModelessDialog(output, 'Range Selector');
}
function selCurRng()
{
var sso=SpreadsheetApp.getActive();
var sh0=sso.getActiveSheet();
var rg0=sh0.getActiveRange();
var rng0A1=rg0.getA1Notation();
rg0.setBackground('#777700');
return rng0A1;
}
function clrRange(range)
{
var sso=SpreadsheetApp.getActive();
var sh0=sso.getActiveSheet();
var rg0=sh0.getRange(range);
rg0.setBackground('#ffffff');
}
pickRange.html
<!DOCTYPE html>
<html>
<head>
<base target="_top">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
var grange='';
function selectRange()
{
$('#btn1').prop('disabled',true);
$('#btn2').prop('disabled',false);
google.script.run
.withSuccessHandler(setResponse)
.selCurRng();
}
function setResponse(r)
{
grange=r;
var msg='You have select the range ' + r;
$('#instr').css('display','none');
$('#rsp').text(msg);
}
function clearAndClose()
{
google.script.run.clrRange(grange);
google.script.host.close();
}
console.log('My Code');
</script>
</head>
<body>
<div id="rsp"></div>
<div id="instr">Please select your desired range.</div>
<input type="button" id="btn1" value="Range Selected" onClick="selectRange();" />
<br /><input type="button" id="btn2" value="close" onClick="clearAndClose();"; disabled="true" />
</body>
</html>
