Protractor - Scroll down and click

问题

I'm trying to simply scroll down in table and click on the element.

This is function which I have:

    var scrollIntoView = function () {
        arguments[0].scrollIntoView();
    }

    element.all(by.css('div.ui-grid-selection-row-header-buttons')).then(function(arr) { 
    var row = arr[8]; 
    browser.executeScript(scrollIntoView, row.getWebElement()).then(function () { 
    row.click(); 
    }); 
    });

This script actually work and even scroll down, bproblem start when i use higher number (index) in arr[];

For example 8 work, but if i use 20 it don't and I'm pretty sure there are like 50 values there so problem in that.

Any hint will help guys

If you want to scroll to an element you can use

    browser.actions().mouseMove(element).perform();

After that the browser will be focusing the element.

This tested example demonstrate how to scroll to an element using javascript and click the same element .

it('scroll to element', function() {
       browser.driver.get('https://www.seleniumeasy.com/');
        var btnSubscribe= element(by.id('mc-embedded-subscribe'));
         browser.executeScript("arguments[0].scrollIntoView();", btnSubscribe);
         browser.sleep(2500);
         btnSubscribe.click();
      });

You can actually do something like this:

$$('div.ui-grid-selection-row-header-buttons').each(function (ele) {
    browser.actions().mouseMove(ele).click().perform();
});

$$ actually represents element.all(by.css('.abc'))

Also you can use filter() if you don't want to click on all the elements but pick elements based on filter criteria like this: https://www.protractortest.org/#/api?view=ElementArrayFinder.prototype.filter
