In Protractor how can I wait until pop appears without depending on timeout?

Question

Is there a wait for protractor to wait for the download popup to appear when the report is ready to download without relying on the timeout because some reports might take longer than others?

browser.driver.wait(
        this.isVisible(locator)
        , 35000, locator_css + ' took too long to be on the DOM.')
        .then(function() {
            return locator.click();
        });
}

Answer 1

我希望等待“下载对话框”可见：

var EC = protractor.ExpectedConditions; browser.wait(EC.visibilityOf(DownloadDialog), 7000, "Download Dialog Not displayed - Timing Out");
