[英]How do you get the number of elements as an number in cypress?
Let's say I have three spans in a div.假设我在一个 div 中有三个跨度。
<div>
<span></span>
<span></span>
<span></span>
</div>
And let's say I have some janky code that counts the number of those spans and outputs the value somewhere else假设我有一些 janky 代码来计算这些跨度的数量并在其他地方输出值
<p>3</p>
In cypress I want to get the length of those spans and get the value that I've produced in my janky code and compare the two.在柏树中,我想获得这些跨度的长度并获得我在我的 janky 代码中产生的值并比较两者。
I've tried cy.get('div span').its('length')
, but that yields the spans as an object...我试过
cy.get('div span').its('length')
,但这会产生跨度作为一个对象......
You can do something like this.你可以做这样的事情。
its('length')
will return a number. its('length')
将返回一个数字。 <p>3</p>
on invoking text gives a string, adding a + in front will convert it into a number +count
. <p>3</p>
在调用文本时给出一个字符串,在前面添加一个 + 会将其转换为一个数字+count
。
cy.get('div span')
.its('length')
.then((len) => {
cy.get('p')
.invoke('text')
.then((count) => {
expect(len).to.equal(+count)
})
})
