isExisting

如果元素存在於 DOM 中，則返回 true。

資訊

與其他元素命令相反，WebdriverIO 不會等待元素存在才執行此命令。

用法

$(selector).isExisting()

範例

index.html

<div id="notDisplayed" style="display: none"></div>
<div id="notVisible" style="visibility: hidden"></div>
<div id="notInViewport" style="position:absolute; left: 9999999"></div>
<div id="zeroOpacity" style="opacity: 0"></div>

isExisting.js

it('should detect if elements are existing', async () => {
    let elem = await $('#someRandomNonExistingElement')
    let isExisting = await elem.isExisting()
    console.log(isExisting); // outputs: false

    elem = await $('#notDisplayed')
    isExisting = await elem.isExisting()
    console.log(isExisting); // outputs: true

    elem = await $('#notVisible')
    isExisting = await elem.isExisting()
    console.log(isExisting); // outputs: true

    elem = await $('#notInViewport')
    isExisting = await elem.isExisting()
    console.log(isExisting); // outputs: true

    elem = await $('#zeroOpacity')
    isExisting = await elem.isExisting()
    console.log(isExisting); // outputs: true
});
