Looping elements in WebdriverIO

Question

I'm trying to loop through a list of links, and perform some actions with each one. I can iterate the elements using elements, but using click inside the forEach doesn't block the next step in forEach, and Selenium goes nuts, as it tries to continue doing actions on elements not in the DOM anymore.

var q = require("q");
var webdriverio = require('webdriverio');
var options = {
    desiredCapabilities: {
        browserName: 'chrome'
    }
};

var clicks = [];

var runner = webdriverio.remote(options);

runner
    .init()
    .url('https://www.google.dk/search?q=burrito')
    .elements(".r").then(function(res){
        res.value.forEach(function(elem){
            console.log(elem);
            clicks.push(
                runner
                    .elementIdClick(elem.ELEMENT)
                    .pause(5000)
                    .back()
                    .pause(2000)
            );
        });

        return q.all(clicks);
    });

How do I make sure the next iteration in the forEach doesn't run before all the code is executed inside the forEach?

Edit: I should have mentioned that I already tried https://github.com/webdriverio/webdriverio/issues/941 and https://github.com/webdriverio/webdriverio/issues/273. I updated my code sample with something more specific.

Answer 1

var runner = webdriverjs
.remote(options)
.init()
.url("http://www.google.com")

 // fetch elements
.elements('a', function(err, res){
    // iterate through elements
    res.value.forEach(function(elem) {
        // execute specific action
        runner.elementIdClick(elem.Element, function(err, res) {
             // callback logic here
             // ...
        })
    })
})

As per this response from the creator of WebdriverIO, the correct way to loop through some links and click them:

runner
    .init()
    .url('https://www.google.dk/search?q=burrito')
    .getText(".r").then(function(res){
        console.log(res);
        res.forEach(function(elem){
            console.log(elem);
            clicks.push(
                runner
                    .click('=' + elem)
                    .back()
            );
        });

        return q.all(clicks);
    });
