Apps Script WebApp - Update text box field from data from a google sheet

Question

I'm busy with an Apps Script Web App and would like to populate input boxes within the web app with data from a google sheet.

I'm trying to retrieve data when a button is clicked and populate fields within the webapp with the data that is retrieved from the sheet. I just can't seem to get the text box fields to be updated after retrieving the data from google sheets.

Any help would be greatly appreciated.

The code I have so far is:

Code.gs file

function doGet() {

  var htmlOutput = HtmlService.createTemplateFromFile("page");

  return htmlOutput.evaluate();



}

function include(filename) {
  return HtmlService.createHtmlOutputFromFile(filename).getContent();
}

var idx;
var nextLead;
var totalLeads;
var remainingLeads;

function assignLead() {
  var ss = SpreadsheetApp.openById("sheetId");
  var ws = ss.getSheetByName("leads");
  var range = ws.getRange(1, 1, ws.getLastRow(), ws.getLastColumn())
  var data = range.getValues();

  //console.log(data);

  var status = data.map(function (row) {
    return row[11];
  });

  //console.log(status);
  
  idx = status.indexOf("unassigned");
  //console.log(idx)
  for (var i = 0; i < data.length; i++) {
    nextLead = data[idx];
    updateStatusAssigned(idx)
  }

  // console.log(nextLead);
  // console.log(data);
}

function updateStatusAssigned(row) {
  var ss = SpreadsheetApp.openById("SheetId");
  var ws = ss.getSheetByName("leads");
  var range = ws.getRange(1, 1, ws.getLastRow(), ws.getLastColumn())
  ws.getRange(idx + 1, 12).setValue("assigned")
}

Modification points:

Unfortunately, the variables declared as the global at Google Apps Script side cannot be used for Javascript side. So nextLead of document.getElementById("name") = nextLead[0]; cannot be used.
- I thought that this is due to the reason of your issue.
In this case, withSuccessHandler can be used.
And, I think that document.getElementById("name") = nextLead[0]; occurs an error. In this case, please modify to document.getElementById("name").value = nextLead[0]; .

When above points are reflected to your script, it becomes as follows.

Modified script:

Google Apps Script side:

Please modify assignLead() as follows.

From:

 for (var i = 0; i < data.length; i++) { nextLead = data[idx]; updateStatusAssigned(idx) } // console.log(nextLead); // console.log(data); }

To:

 for (var i = 0; i < data.length; i++) { nextLead = data[idx]; updateStatusAssigned(idx) } // console.log(nextLead); // console.log(data); return nextLead; // Added }

Javascript side:

From:

 function getLeadData(){ google.script.run.assignLead() document.getElementById("name") = nextLead[0]; }

To:

 function getLeadData(){ google.script.run.withSuccessHandler(nextLead => { document.getElementById("name").value = nextLead[0]; }).assignLead(); }

Note:

In this modified script, it supposes that your function of assignLead() works fine and nextLead is the correct value you want. Please be careful this.
