Python常见问题
我有一个表单，让用户有机会输入一个项目名称，然后单击一个按钮“设置”它。然后运行一个JavaScript来禁用输入框和按钮，并启用一些需要为项目设置的其他字段。当单击提交时，我运行另一个JavaScript来重新启用禁用的项目名称HTML文本输入框。你知道吗
当项目被提交时，由于某种原因，项目名称不会被提交，而表单中的所有内容都会被提交。我尝试在表单头标签中使用onSubmit=，在提交按钮上也使用onClick。你知道吗
我正在使用Python处理服务器端。你知道为什么我没有在表单提交中得到projectName变量吗？你知道吗
我从python脚本中得到的错误是：
/var/www/ARCHlang/cgi-bin/pythonTest.cgi in ()
32 myN = 0
33 myC = 0
34 projectPath = "../prPages/userFiles/" + projectName + "/"
35 mainTclPath = projectPath + "pr.tcl"
36 systemCheckpointToOpen = "" projectPath undefined, projectName = None
