Question

接收到后端响应后，下拉菜单基本上需要很长时间才能获得负载。如果我等待大约8秒钟，那么它可以工作。但是，不想在这里硬编码等待。任何想法可能出了什么问题？我也无法识别CSS。

cy.get('input').last().type(`{selectall}${value}`);
        cy.get('mat-option > span').then(option => {
            if (option.get(0).textContent === 'Loading...') {
                cy.wait(5000);
            }
        });   

cy.containsCaseInsensitive(value, 'mat-option').first().scrollIntoView().debug().click();

错误日志-

CypressError: Timed out retrying: cy.click() failed because this element is detached from the DOM.

<mat-option _ngcontent-gcj-c21="" class="mat-option ng-star-inserted" role="option" ng-reflect-value="[object Object]" tabindex="0" id="mat-option-104" aria-disabled="false" style="">...</mat-option>

Cypress requires elements be attached in the DOM to interact with them.

The previous command that ran was:

  > cy.debug()

This DOM element likely became detached somewhere between the previous and current command.

Common situations why this happens:
  - Your JS framework re-rendered asynchronously
  - Your app code reacted to an event firing and removed the element

You typically need to re-query for the element or add 'guards' which delay Cypress from running new commands.

Answer 1

您可以通过这种方式尝试

cy.get('input').last().type(`{selectall}${value}`);
        cy.get('mat-option > span').then(option => {
            //if (option.get(0).textContent === 'Loading...') {
                //cy.wait(5000);
            //}

            cy.containsCaseInsensitive(value, 'mat-option').first().scrollIntoView().debug().click();
        });

为了等待网络响应，您可以为网络请求添加别名并等待它们。

在此处查看有关赛普拉斯的文档：https://docs.cypress.io/guides/guides/network-requests.html#Flake

cy.route('/search*', [{ item: 'Book 1' }, { item: 'Book 2' }]).as('getSearch')

// our autocomplete field is throttled
// meaning it only makes a request after
// 500ms from the last keyPress
cy.get('#autocomplete').type('Book')

// wait for the request + response
// thus insulating us from the
// throttled request
cy.wait('@getSearch')

通过上面的链接，文档中提供了更多示例。

Answer 3

也许是一个较晚的答案，但对遇到同样问题的其他人可能很有用，有时使用赛普拉斯jQuery包装器是个好主意。

Cypress.$('.mySelector').trigger('click');

Answer 4

我确实遇到了同样的问题保持柏树等待一段时间直到页面加载解决了分离元素的问题

示例

cy.wait(3000)
cy.get(growth.tpsl_input_sessionName).clear().type(sessionName);

CypressError：超时重试：cy.click（）失败，因为此元素与DOM分离
