Load HTML content via AJAX in React ListView component

14 Apr 2021 / 2 minutes to read

We can set external HTML page content as template for our ListView component by making use of AJAX call.

        this.ajax = new Ajax('./template.html', 'GET', false);
        this.ajax.onSuccess = (e: string) => {
            this.template = e;
        };
        this.ajax.send();

In the below sample, we have rendered smartphone settings template from external HTML file.
