I'm making a Google Chrome extension. I'm trying to open new tabs and group them. I have urls as an array. But chrome.tabs.group function doesn't wait until all tabs open.
var ourTabIds = []
for(const url of urls) {
chrome.tabs.create({active: false, url : url},tab => {
ourTabIds.push(tab.id)
})
}
chrome.tabs.group({tabIds : ourTabIds}, groupId => {console.log(groupId)})
The group function works when the ourTabIds is still empty. So it gives errors.
Why it doesn't wait? How can I fix that?
You could promisify chrome.tabs
and then use Promise.all
function createTab(input){
return new Promise(resolve => {
chrome.tabs.create(input,tab => resolve(tab))
});
}
and then you code becomes
(async function doIt(){
var tabs = await Promise.all(urls.map(url => createTab({active: false, url : url})));
chrome.tabs.group({tabIds : tabs.map(t => t.id)}, groupId => {console.log(groupId)})
})()
var ourTabIds = [];
var countTabs = 0;
for(const url of urls) {
chrome.tabs.create({active: false, url : url},tab => {
ourTabIds.push(tab.id)
countTabs++;
if (countTabs==urls.length){
chrome.tabs.group({tabIds : ourTabIds}, groupId => {console.log(groupId)})
}
})
}
The function chrome.tabs.create()
uses a callback as parameter. You should either convert that to Promises and finish it all with.then() or check if it is the last url (changing from of to in )
var ourTabIds = []
for(const index in urls) {
chrome.tabs.create({active: false, url : urls[index]}, tab => {
ourTabIds.push(tab.id)
if (index === urls.length - 1 ) { // last url
//call when EVERYTHING has been pushed by the callback
chrome.tabs.group({tabIds : ourTabIds}, groupId => {console.log(groupId)})
}
})
}
