I am quite new to this all, so i am pretty sure this is a simple oversight on my part, but i cant get it to run.
When i deploy the code below and click on the button, it does not do anything. When i inspect the html in my browser, it says "userCodeAppPanel:1 Uncaught ReferenceError: csvHTML is not defined at HTMLInputElement.onclick"
When i run the function csvHTML from Code.gs, I can see the expected results in my Logger.log, so it seems the problem does not lie in my code.gs
What i am trying to achieve is showing the csv results in html. When all works fine, i will want to work with the data in some other way.
Attached below is my code.
Index.html:
<!DOCTYPE html>
<!-- styles -->
<?!= HtmlService.createHtmlOutputFromFile("styles.css").getContent(); ?>
<div class="content">
<h1>csv representation</h1>
<input class="button" type="submit" onclick="html();" value="Refresh" id="refresh"><br>
<div id="tabel"></div>
<svg class="chart"></svg>
</div>
<!-- javascript -->
<script src="//d3js.org/d3.v3.min.js"></script>
<?!= HtmlService.createHtmlOutputFromFile("chart.js").getContent() ?>
<?!= HtmlService.createHtmlOutputFromFile("main.js").getContent() ?>
<script>
function html()
{
var aContainer = document.createElement('div');
aContainer.classList.add('loader_div');
aContainer.setAttribute('id', 'second');
aContainer.innerHTML = "<div class='loader_mesage'><center>Fetching csv list. Please be patient!<br /> <br /><img src='https://i.ibb.co/yy23DT3/Dual-Ring-1s-200px.gif' height='50px' align='center'></img></center></div>";
document.body.appendChild(aContainer);
google.script.run
.withSuccessHandler(showTable)
.csvHTML();
}
function showTable(tabel)
{
document.getElementById("tabel").innerHTML = tabel;
var element = document.getElementById("second");
element.parentNode.removeChild(element);
}
</script>
and Code.gs:
function doGet(e) {
return HtmlService.createTemplateFromFile("index.html")
.evaluate()
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
// Fecth Data and make a csv output.
function csvHTML()
{
var query = "{ 'query': 'SELECT * FROM `<some table>` limit 1000;', 'useLegacySql': false }";
var job = BigQuery.Jobs.query(query, <projectName>);
var json = JSON.parse(job);
var tabel = json2csv(json);
Logger.log(tabel)
return tabel;
}
function json2csv(json, classes) {
var headerRow = '';
var bodyRows = '';
classes = classes || '';
json.schema.fields.forEach(function(col){
headerRow +=col.name+",";
})
json.rows.forEach(function(row){
row.f.forEach(function(cell){
bodyRows +=cell.v+",";
})
})
return headerRow + bodyRows }
