How to call a column in JS DDX bricks

ColinHaze

Hi,

I wrote this script to switch the sentence on a landing page to switch every 5 seconds. It currently does that. However, as soon as I insert the column data it no longer reads the first sentence and doesn't switch sentences. What might I be doing wrong? Still learning JS so I appreciate the help. The script works but as soon as I try to input the display name it breaks.

var columnData = input['Display Name'];
var header = document.getElementById('header');
var sentences = [
'Hello ' + columnData[0], //This is no longer displayed (if i remove columndata[0] it works.
'What KPI group would you like to view?'
];
var sentenceIndex = 0;

function changeHeader() {
header.innerHTML = sentences[sentenceIndex];
sentenceIndex = (sentenceIndex + 1) % sentences.length;
}

// Initial call to display the first sentence
changeHeader();

// Set interval to change header text every 5 seconds
setInterval(changeHeader, 5000);

How are you setting the value of inputData? Are you querying your dataset? Is your column data an array or is it set to nothing?

Those questions allowed me to answer my own question. Thank you
