CypressError：重试超时：cy.click() 失败，因为此元素已与 DOM 分离

Question

一旦收到后端响应，下拉菜单基本上需要很长时间才能自行加载。如果我等待大约 8 秒，那么它可以工作。但是，不想在这里对等待进行硬编码。知道可能出了什么问题吗？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

我确实遇到了同样的问题 让柏树等待一段时间直到页面加载 解决了分离元素的问题

例子

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

Answer 2

为了等待网络响应，您可以为网络请求设置别名并等待它们。

在此处查看赛普拉斯的文档：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')

点击上面的链接可以在文档中找到更多示例。

Answer 3

我遇到了同样的问题，但你可以解决它

cy.get('.mySelector').should('be.visible').click({force:true});

Answer 4

也许是一个迟到的答案，但对其他有同样问题的人有用，有时使用 Cypress jQuery 包装器可能是个好主意。

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

Answer 5

你可以这样试试

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();
        });
