如何等待硒页面重新加载？

Question

考虑以下代码：

$this->visit('/');
$text = $this->byCssSelector('.some-element')->text();
$this->byCssSelector('.some-link')->click();
# how do I wait for a new page to be loaded here?
$this->assertEquals($text, $this->byCssSelector('.some-element')->text());

Answer 1

您可以设置（通过 js 调用）window.is_old_page = true，并检查直到 undefined

Answer 2

从我在网上看到的，尽可能避免执行javascript，所以我想出了非javascript的解决方案：

$this->visit('/');
$text = $this->byCssSelector('.some-element')->text();
$this->waitForPageReload(function () {
    $this->byCssSelector('.some-link')->click();
}, 5000);
$this->assertEquals($text, $this->byCssSelector('.some-element')->text());

function waitForPageReload($navigate_f, $timeout) {
    $id = $this->byCssSelector('html')->getId();
    call_user_func($navigate_f);
    $this->waitUntil(function () use ($id) {
        $html = $this->byCssSelector('html');
        if ($html->getId() != $id)
            return TRUE;
    }, $timeout);
}
