Javascript 为什么我的动态表单未提交？

我正在创建一个动态表单来提交，输入元素很少，但它不发送请求。我过去经常检查

这是我的密码

var form_ref = document.createElement("form");
form_ref.id = "viewform";
form_ref.name = "viewform";
form_ref.action = "/csm/showResult.action";
form_ref.method = "post";
form_ref.target = "_self";

var cfgidField = document.createElement("input");
cfgidField.name = "cfgid";
cfgidField.type = "text";
cfgidField.value = configid;
form_ref.appendChild(cfgidField);

var cfgnameField = document.createElement("input");
cfgnameField.name = "cfgname";
cfgnameField.type = "text";
cfgnameField.value = configname;
form_ref.appendChild(cfgnameField);

var cfgdescField = document.createElement("input");
cfgdescField.name = "cfgdesc";
cfgdescField.type = "text";
cfgdescField.value = configdesc;
form_ref.appendChild(cfgdescField);

var cfgenvField = document.createElement("input");
cfgenvField.name = "cfgenv";
cfgenvField.type = "text";
cfgenvField.value = configenv;
form_ref.appendChild(cfgenvField);

var cfgfileField = document.createElement("input");
cfgenvField.name = "cfgfile";
cfgenvField.type = "text";
cfgenvField.value = absolutepath;
form_ref.appendChild(cfgfileField);

var cfgdateField = document.createElement("input");
cfgenvField.name = "updatedDate";
cfgenvField.type = "text";
cfgenvField.value = absolutepath;
form_ref.appendChild(cfgdateField);

form_ref.submit();

也许你也有同样的问题：

它基本上是说在提交之前将其附加到document.body中
