无论出于何种原因，这种形式document.write都使用 javascript在页面上绘制单选按钮，我不知道如何规避它。

在这里和谷歌上进行了一些调查之后，您似乎可以使用 Mechanize 手动重新创建表单字段，然后像往常一样提交它。

因此，我将代码设置如下：

br = mechanize.Browser(factory=mechanize.RobustFactory())
response = br.open(url)
br.select_form(nr=0)
br.form.set_all_readonly(False)
br.form.new_control('radio', 'DATASOURCE', {'value':'FILE', 'checked':'true'})
br.form.add_file(open('weather_info.csv'), 'text/csv', 'weather_info.csv', name='FILENAME')
br.form.fixup()
response = br.submit()

现在，如果我打印表单，它确实会显示为底部的字段之一。

<HiddenControl(CGIREF=/calludt.cgi/DDFILE1)>
  <HiddenControl(USE=MODEL)>
  <HiddenControl(MODEL=CM)>
  <HiddenControl(CROP=apples)>

  <FileControl(FILENAME=weather_scrape.csv)>
  <IgnoreControl(Submit=<None>)>
  <RadioControl(DATASOURCE=[*FILE])>>

但是，在运行代码并提交表单时，什么也没有发生；它停留在它开始的同一页面上。

有没有办法使用 Python 解决这个问题？

编辑：

我意识到提交按钮也是javascript；它有一个与之onclick相关的事件，所以..就python解决方案而言，我可能不走运..

<input type="button" name="Submit" value="Continue" onclick="SetDDinfo()">

我尝试手动向表单添加一个按钮，如此处所示。

br.form.new_control('submit', 'Button', {})

但仍然没有运气。

Submit的onclick方法调用以下函数：

function SetDDinfo(){
     var DDstuff = new Array(21);
     var checksok = true;
     // alert("SetDDinfo DDparms: " + DDparms);
     for (var i = 0; i < 21; i++){
       DDstuff[i] = DDparms[i];
     }
     // This section for MODEL
        document.DDCOMPUTE.USE.value = "MODEL";
        DDstuff[4] = "MODEL"
        with(document.DDCOMPUTE) {
          DDstuff[5] = "E";  // english units
          DDstuff[6] = "";  // lower threshold (null)
          DDstuff[7] = "";   // upper threshold (null)
          DDstuff[8] = "SS"; // dd method: (default)
          DDstuff[9] = "H"; // cutoff: (default)
          DDstuff[10] = "CM";         // organism model code: CM, NOW, etc.
          if (COUNTY.selectedIndex < 0) {
             DDstuff[11] = "";
          } else {
             DDstuff[11] = COUNTY.options[COUNTY.selectedIndex].value;  // county
          }
          if (DATASOURCE[0].checked == "1") {
             DDstuff[13] = "STATION";  // data from database
             DDstuff[14] = "";
          } else {
             if (DATASOURCE[1].checked == "1") {
                DDstuff[13] = "FILE";  // data from user file
                DDstuff[14] = FILENAME.value;
             } else {
                DDstuff[13] = "ENTRY";  // data from user entry
                DDstuff[14] = "";
             }
          }
        }
        // MODEL error checks. Return false to abort SUBMIT.
        if (DDstuff[11] == "" && DDstuff[13] == "STATION") {
           alert ("ERROR: You must select a County.");
           checksok = false;
           return checksok
        }
        if (DDstuff[10] == "") {
           alert ("ERROR: You must select a Model.");
           checksok = false;
           return checksok
        }
        if (DDstuff[13] == "FILE" && DDstuff[14] == "") {
           alert ("ERROR: You must specify a filename.");
           checksok = false;
           return checksok
        }
        // Wx source error checks. Return false to abort SUBMIT.
        if (DDstuff[11] == "" && DDstuff[13] == "STATION") {
           alert ("ERROR: You must select a County.");
           checksok = false;
           return checksok
        }
        if (DDstuff[13] == "FILE" && DDstuff[14] == "") {
           alert ("ERROR: You must specify a filename.");
           checksok = false;
           return checksok
        }

     DDstuff[14] = "";     // Don't bother saving filename, since not displayed and must be re-specified.
     var DDitems = DDstuff.join(",");
     SetCookie ('DDinfo', DDitems, exp);
        // alert ("DDstuff[13]: "+DDstuff[13]);
        if (DDstuff[13] == "STATION") {
           document.DDCOMPUTE.action = "/calludt.cgi/DDSTATIONLIST";
           document.DDCOMPUTE.method = "GET";
           document.DDCOMPUTE.encoding = "application/x-www-form-urlencoded";
        } else {
           if (DDstuff[13] == "FILE") {
              document.DDCOMPUTE.action = "/WEATHER/textupload.cgi";
              document.DDCOMPUTE.method = "POST";
              document.DDCOMPUTE.encoding = "multipart/form-data";
           } else {
              document.DDCOMPUTE.action = "/calludt.cgi/DDENTRY1";
              document.DDCOMPUTE.method = "GET";
              document.DDCOMPUTE.encoding = "application/x-www-form-urlencoded";           }
        }
        // alert ("document.DDCOMPUTE.action = " + document.DDCOMPUTE.action);
        document.DDCOMPUTE.submit()
     return checksok
   }  // ................................................

我不精通 javascript，但该函数的前半部分似乎正在处理我不感兴趣的表单部分 - 当单选按钮在 position 时one。第二点对我来说很难理解，但它正在发布一个帖子，/WEATHER/textupload.cgi我明天必须检查流量。也许我可以通过什么来重新创建它需要的urllib2东西？
