This form使用javascript的document.write来绘制页面上的单选按钮，我无法弄清楚如何规避它。
在这里和Google上进行一些调查后，您似乎可以使用Mechanize手动重新创建表单字段，然后照常提交。
所以，我按如下方式设置了代码：
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，它确实显示为底部的一个字段。

然而，在运行代码并提交表单时没有任何反应;它保持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onclick事件，所以......就python解决方案来说，我可能会运气不好..
<input type="button" name="Submit" value="Continue" onclick="SetDDinfo()">
我尝试手动向表单添加按钮here。
br.form.new_control('submit', 'Button', {})
但仍然没有运气。
Submit的{{1}}方法调用以下函数：
onclick我不能流利使用javascript，但是函数的前半部分似乎正在处理我不感兴趣的表单部分 - 当单选按钮位于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.

DDstuff[11] = "";

DDstuff[11] = COUNTY.options[COUNTY.selectedIndex].value; // county

DDstuff[13] = "STATION"; // data from database
DDstuff[14] = "";

DDstuff[14] = FILENAME.value;

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

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";

时。第二位对我来说很难跟进，但它正在向one发帖子我明天必须检查出来的流量。也许我可以通过/WEATHER/textupload.cgi或其他东西重新创建它需要的东西？
