使用操纵符更改属性的值 [英] changing the value of attributes using puppeteer

问题描述

我有一个元素"input [name = startdate]"，属性为"value ="2018-06-20""

I have an element 'input[name=startdate]' with an attribute 'value="2018-06-20"' instead of using puppeteer to interact with the calendar that is used to change the date, is there anyway I can use puppeteer to set the value instead?

类似...

让newDate ='2018-01-01'

let newDate = '2018-01-01'

value.innerHTML = newDate

value.innerHTML = newDate

推荐答案

我能够弄清楚它，如果有其他人遇到同样的问题，我会在这里发布.

I was able to figure it out and I'm posting it here in case anyone else has the same problem.

await page.$eval('input[name=startdate]', e => e.setAttribute("value", "2018-01-01"))

如果要将日期设置为变量...

If you want to set the date as a variable...

const randomDate = '2018-01-01'
await page.$eval('input[name=startdate]', (e, randomDate) => { 
    e.setAttribute("value", randomDate),
    randomDate
    )}
