量角器等待元素进入 DOM [英] Protractor waiting for element to be in DOM

问题描述

我在使用 Protractor 时遇到了一些问题.我有一个非常奇怪的 ui-router 状态，它很难脱离其他元素来开始处理页面.有没有办法告诉量角器等到元素最终出现在 DOM 中?不可见/显示，但实际创建?我一直在尝试使用等待元素，但它显然无法被选中.

I have been having some trouble using Protractor. I have a really weird ui-router state where its hard to go off of other elements to start working with the page. Is there any way to tell protractor to wait until an element finally appears in the DOM? Not visible/displayed, but actually created? I keep trying to use wait for the element but it is clearly not available to be selected.

browser.driver.wait(function () {
    return elem.isDisplayed();
});

推荐答案

你应该可以使用 browser.wait 和 presenceOf ExpectedCondition:

You should be able to use browser.wait together with the presenceOf ExpectedCondition:

var until = protractor.ExpectedConditions;
browser.wait(until.presenceOf(elem), 5000, 'Element taking too long to appear in the DOM');
