我有这个例程,使用selenium-webdriver进行NPM - require('selenium-webdriver')
:
function run(){
driver.get(cdthost + '/#!/home');
driver.navigate().refresh(); // same problem, with or without this line
let acqId = acq._id;
assert(acqId, 'acqId is not defined.');
// on the next line we wait to ensure that the page is loaded
driver.wait(until.elementLocated(By.id(`open-editing-acqId-${acqId}`)), 3000);
driver.findElement(By.id(`open-editing-acqId-${acqId}`)).click();
let file = path.resolve($root + '/csv-data/IT-DE-Jasper.csv');
let el = driver.findElement(By.id(`import-file-acqId-${acqId}`));
driver.wait(until.elementIsVisible(el), 2000);
el.sendKeys(file);
return driver.findElement(By.id(`submit-file-acqId-${acqId}`)).click().then(function () {
return Promise.delay(2000)
})
.catch(function (err) {
console.error('\n\n', ' => Suman caught promise rejection => ', err.stack || err);
return Promise.reject(err);
});
}
我称之为一次,它完美无缺。我再次调用它,它在页面上找不到任何元素,即使我调用refresh()。
任何想法为什么这会在第一次起作用,但不是在那之后呢?
答案 0 :(得分:0)
好吧,这解决了它:
// Callback to run when data is ready
function reqListener() {
// Parse the JSON text to an object so we can get just one property
var data = JSON.parse(this.responseText);
// Append that value to the DOM.
document.querySelector("#demo").innerHTML = data.body;
}
// Create a new ajax requst
var oReq = new XMLHttpRequest();
// Fire callback on load event
oReq.addEventListener("load", reqListener);
// Create the connection to our API
oReq.open("GET", "https://jsonplaceholder.typicode.com/posts/1");
// Fire the request
oReq.send();
有点令人失望......我会向selenium-webdriver人提出问题。
另一种可行的方式(未经测试)就是这样:
let passCount = 0;
// ...
function run(){
if(passCount < 1){
driver.get(cdthost + '/#!/home');
}
else{
driver.navigate().refresh();
}
passCount++;
}
但我不确定这是否更理想,或更不理想。
