使用 Splinter 在网站的 textarea 中填充表格或值列表

Question

我正在尝试编写一个脚本来自动搜索多个条目。这是输入：

<mirna-1>
<mirna-2>
<mirna-3>
    :    
    :   

网址是https://www.mirnet.ca/miRNet/faces/upload/MirUploadView.xhtml

如何将 mirna-1,.... 填充到 miRNA 列表框中。我做了以下尝试，但都失败了：

gecko = os.path.normpath('~/geckodriver')
nirnet_Results = []`
browser = Browser(executable_path=gecko)
browser.visit('https://www.mirnet.ca/miRNet/faces/home.xhtml')

# click miRNA_list
xpath = '//*[@id="j_idt39:j_idt55"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)

#Select Human
xpath = '//*[@id="form:j_idt34"]/div[3]/span'
browser.find_by_xpath(xpath).click()
time.sleep(1)
xpath = '//*[@id="form:j_idt34_1"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)

# select miRBase ID type
xpath = '//*[@id="form:j_idt38"]/div[3]/span'
browser.find_by_xpath(xpath).click()
time.sleep(1)
xpath = '//*[@id="form:j_idt38_1"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)

# select Tissue type
xpath = '//*[@id="form:sourceOpt"]/div[3]/span'
browser.find_by_xpath(xpath).click()
time.sleep(1)
xpath = '//*[@id="form:sourceOpt_1"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)

# select target type
xpath = '//*[@id="form:targetOpts"]/div[3]/span'
browser.find_by_xpath(xpath).click()
time.sleep(1)
xpath = '//*[@id="form:targetOpts_1"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)

# Fill miRNA list
xpath = '//*[@id="form:listData"]'
browser.find_by_xpath(xpath).click()
time.sleep(1)
for mir in known_mir:
    browser.fill('form:listData',mir)
    browser.fill('form:listData','\n')

我在开始下拉列表中选择选项方面取得了成功，当我尝试将名称列表粘贴到 miRNA 列表中时，我得到的所有名称都是这样的：

<mirna-1><mirna-2><mirna-3>....

而正确的格式是每个名字都应该在下一行。这该怎么做。请建议。谢谢。

您可以使用Selenium Chrome Driver 和python 填写此表格。如果您以前没有使用过硒并且想使用硒。但是这里是硒的official website。

到install selenium 使用命令行

pip install -U selenium

---

您需要在compatibility的基础上从以下网站website Chromedriver下载chrome驱动程序，如chrome browser支持的chrome driver。总是喜欢最新版本的chrome驱动程序和chrome浏览器。

这是填写表格的硒代码

Answer 2

虽然我会推荐 selenium 用于这样的事情，但您似乎想坚持使用 splinter。使用 splinter 进行以下修复。重现此问题时，每次运行 browser.fill() 时，它都会替换已写入的文本。由于您的代码中没有包含 known_mir 的内容，因此我假设它是一个列表（如果我错了，请纠正我）。我尝试将您想要放入表单的内容结合起来，并且效果很好。

替换：

for mir in known_mir:

    browser.fill('form:listData',mir)

    browser.fill('form:listData','\n')

与：

browser.fill('form:listData', '\n'.join(mir for mir in known_mir))

我的代码所做的只是组合known_mir 中的每个字符串。
