如何使我的页面在从下拉菜单或文本字段获取数据之间进行选择？

Question

thanks to some help from yesterday from stackoverflow, I've made progress in my code. 感谢昨天从stackoverflow获得的一些帮助，我的代码取得了进步。 But I have a question, concerning my page. 但是我有一个关于我的页面的问题。 Here is my code 这是我的代码

#May 17 - Writing the analysisV2.html file and starting the code
#May 19 - Tables, and the like
#May 20 - Writing if statements for drop-down menu, building the page.
#May 21 - Working on text fields and getState

Essentially, my page works so that you have a drop-down menu to choose from (choosing one of these values: eg "High SAT Scores" and "Race Demographics" causes my python code to generate a page that with tables, or descriptions concerning the drop-down menu option), or a text field (which searches for a state in my CSV files, and returns a table-row with the data about that particular State). 本质上，我的页面工作正常，因此您可以从下拉菜单中进行选择（选择以下值之一：例如，“ SAT高得分”和“种族人口统计”会导致我的python代码生成带有表格或相关说明的页面下拉菜单选项）或文本字段（在我的CSV文件中搜索状态，并返回包含该特定状态的数据的表行）。 Using cgi.FieldStorage() Python collects the value that is submitted through the HTML form. 使用cgi.FieldStorage（）Python收集通过HTML表单提交的值。 However, how do I write the code so that I only send a value from the text-field only, through the HTML form. 但是，如何编写代码，以便仅通过HTML表单仅从文本字段发送值。

Ie if I do not want to use the drop-down menu, and instead only want to use the text-field to find a state in particular and not submit form data through the drop-down menu, how do I do that? 即，如果我不想使用下拉菜单，而是只想使用文本字段来查找特定状态，而不想通过下拉菜单提交表单数据，该怎么办？

Answer 1

I am not sure whether I am missing something here but, assuming 'on' is the name of your text field, you can check to see whether the text field is empty like so: 我不确定在这里是否丢失了某些内容，但是假设文本字段的名称为“ on”，则可以像下面这样检查文本字段是否为空：

if 'on' in form and form['on']:
    doSomethingWithOn()
else:
    doSomethingWithDrop()
