How can I prevent the WhatsApp Web URL from opening in a new tab if there is already a WhatsApp Web tab open?
const msg = "*Greetings From "+this.previewData.unit_name+" "+this.previewData.unit_location+"* ";
const full = `${msg}\nPlease click the link below to get your receipt. \n ${url}`;
const whatsappUrl = "https://web.whatsapp.com:/send?text=" + encodeURIComponent(full);
window.open(whatsappUrl, '_blank');One way to prevent a window from opening again on the second trigger is by using a local variable to store the reference. This ensures that the window is not opened repeatedly.
const message = "Greetings From "+this.previewData.unit_name+" "+this.previewData.unit_location+" ";
const fullMessage = `${message}\nPlease click the link below to get your receipt. \n ${url}`;
const whatsappLink = "https://web.whatsapp.com:/send?text=" + encodeURIComponent(fullMessage);
let windowReference = null;
if(!windowReference) {
windowReference = window.open(whatsappLink, '_blank');
}
