Array not updating
I am doing some browser automation and starting getting into javascript very recently. At the moment I am very puzzled with the following:
module.exports = {
main_page(browser) {
var pos;
var tmp = ; //A
browser
.url(myUrl)
.waitForElementVisible('body', 1000)
.assert.elementPresent('#id > ul > li:nth-child(1)')
for (var i = 1 ; i <= 6; i+=1){
browser.getText(`#id > ul > li:nth-child(${i})`, function(result){
pos = result.value.substr(-1) //B
tmp.push(pos)
})
}
tmp.forEach(function(element) { //C
console.log(element);
});
...
browser.end();
},
}
I am trying to push pos into my array tmp so that I can use that to do something later.
What I can't understand is why isn't my array at A being updated by my code at B. My forEach at C doesn't log anything. Can someone help me understand what is happening or explain how to properly do it?
Any input is welcome, thank you.

browseris an async process. Put theforEachinside the callback after thepush.

The answer to this StackOverflow post might actually be what you are looking for.
browser.getText returns a promise, so you should do something like this
browser.getText(`#id > ul > li:nth-child(${i})`).then(function(result){
pos = result.value.substr(-1) //B
tmp.push(pos)
})
Promises are basically used with asynchronous data. Check out this https://developers.google.com/web/fundamentals/primers/promises to know more about promises.
