PhantomJS

Question

我无法使用 PhantomJS 单击按钮。填充文本框效果很好。我想使用纯 js（没有 jquery）。想法？

var page = require('webpage').create();

page.open('https://www.somepage.com/login', function(status) {
console.log(">page loaded");

page.render('page.png');

page.evaluate(function () {
    var username = "";
    var password = "";
    document.getElementById('login-input').value = username; //works
    document.getElementById('passwd').value = password; //works
    document.getElementsByName('login_button').click(); //this doesn't click the button
});

console.log(">form submitted");

page.render('page1.png');

phantom.exit();
});

您必须在以下代码中触发功能 x.click(); 在点击功能之后，如下所示。

var x = document.getElementById("btn");
document.getElementById("btn").addEventListener('click', function() {

  console.log("Clicked !!");

})

x.click();

<button id="btn">Click</button>

PhantomJS - 无法单击表单按钮

PhantomJS - Can't click the form button

javascript
