如何使用node.js在Selenium Webdriver中选择下拉值

Question

我有以下HTML结构：

<button class="dropdown-toggle selectpicker btn btn-primary" data-toggle="dropdown" type="button" data-id="strategic_reseller_country" title="United States">
<div class="dropdown-menu open" style="max-height: 245.6px; overflow: hidden; min-height: 40px;">
<ul class="dropdown-menu inner selectpicker" role="menu" style="max-height: 243.6px; overflow-y: auto; min-height: 38px;">
<li class="" rel="0">
<a class="" style="" tabindex="0">
<span class="text"/>
<i class="glyphicon glyphicon-ok icon-ok check-mark"/>
</a>
</li>
<li rel="1">
<a class="" style="" tabindex="0">
<span class="text">Andorra</span>
<i class="glyphicon glyphicon-ok icon-ok check-mark"/>
</a>
</li>
<li rel="2">
<a class="" style="" tabindex="0">
<span class="text">United Arab Emirates</span>
<i class="glyphicon glyphicon-ok icon-ok check-mark"/>
</a>
</li>
<li rel="3">
<a class="" style="" tabindex="0">
<span class="text">Afghanistan</span>
<i class="glyphicon glyphicon-ok icon-ok check-mark"/>
</a>
</li>
<li rel="4">
<li rel="5">
<li rel="6">
<li rel="7">
<li rel="8">
<li rel="9">
<a class="" style="" tabindex="0">
<span class="text">Netherlands Antilles</span>
<i class="glyphicon glyphicon-ok icon-ok check-mark"/>
</a>
</li> 
</ul>
</div>

那么我如何从清单中获得该物品？

我是Node.Js（JavaScript）的新手，所以我不知道如何实现它，node.Js但是可以在Java中实现，如下所示：

Select dropdown = new Select(driver.findElement(By.class("dropdown-menu inner selectpicker"))); 
dropdown.selectByVisibleText("Andorra");

Answer 1

我会为此使用Cheerio。

module.exports = {
    "login": function (browser) {
        var cheerio = require("cheerio")

        browser
            .url("http://www.wikipedia.org")
            .waitForElementVisible('body', 1000)
            .waitForElementVisible('select#searchLanguage', 1000)
            .source(function(result) { // .source() dump the page source in the variable
                $ = cheerio.load(result.value)
                var num_languages = $('select#searchLanguage option').length
                console.log('Wikipedia.org Languages: ' + num_languages);
            })
            .end();
    }
};

或者只是使用.execute()命令
