im试图选择一个带有div的图像元素,然后使用nightmare.js单击它。下面是我要点击的元素,下面是我正在使用的代码。

我是nightmare.js的新手,并且在网络抓取中非常感谢。
答案 0 :(得分:0)
您的代码应该可以正常工作,如果您想查看浏览器GUI,则可能要添加的唯一内容是评估后的.then()或将评估放在.then()中。 下面是有效的代码,运行时它会检查页面上的所有复选框。
var Nightmare = require('nightmare')
var nightmare = Nightmare({ show: true })
nightmare
.goto('https://materializecss.com/checkboxes.html')
.wait('label input[type="checkbox"]')
.evaluate(function() {
let checkboxes = document.querySelectorAll('label input[type="checkbox"]')
for (let checkbox of checkboxes) checkbox.click()
})
.then(function() {
console.log('Im here just to show the GUI')
})
或
var Nightmare = require('nightmare')
var nightmare = Nightmare({ show: true })
nightmare
.goto('https://materializecss.com/checkboxes.html')
.wait('label input[type="checkbox"]')
.then(function() {
return nightmare.evaluate(function() {
let checkboxes = document.querySelectorAll('label input[type="checkbox"]')
for (let checkbox of checkboxes) checkbox.click()
})
})
