JavaScript - 在变量中连接一个值

Question

I know that this is somewhat, very basic question, but.. I have to create a cypress element, for which I have to concatenate a value between variables.

Like I have this value

const value = "100 - 299"

and I have to print a value within a string, ie

cy.get('[data-value="100 - 299"]')

I am trying everything but unable to do so. Can someone help me on this?

Answer 1

我会考虑模板文字- 也称为反引号

cy.get(`[data-value="${value}"]`)

Answer 2

You could consider concatenation.

const value = "100 - 299"

cy.get('[data-value="' + value + '"]')

Or template literals

cy.get(`[data-value="${value}"]`)

Or pre-concatenation:

const value = "100 - 299"
const fullstring = '[data-value="' + value + '"]'
cy.get(fullstring)
