How to display the image of instead of empty array-CodePudding

const customImage = tmpl.customImage ? tmpl.customImage.map(c => c.url) : "https://yourl img here";

here tmpl.customImage is getting empty array[] so i want to display a default image instead of empty. But it is not fetching to default image it is showing empty...

How about checking it length?

const customImage = tmpl.customImage.length ? tmpl.customImage.map(c => c.url) : "https://yourl img here";

CodePudding user response：

use instead of that: const customImage = tmpl.customImage.length ? tmpl.customImage.map(c => c.url) : "https://yourl img here";

CodePudding user response：

give your image url link in that array make that variable and use res.render to render your file

Is tmpl.customImage already an array, then why assign an array to customImage ?

You can handle the empty array here:

tmpl.customImage.push({"url":"https://yourimghere"}); // add to the end
const customImage = tmpl.customImage.shift(); // take from the top
