一个很奇怪的问题，关于get提交的

Question

哪位遇到过这种情况，我的JAVASCRIPT是这样写的
var frm = document.getElementById("frmUser");frm.action = "../../servlet/ManagerServlet.do?id=" + id;
frm.method = "get";
frm.submit();
结果提交结束后URL里面变成了
http://localhost:8080/PatientCase/servlet/ManagerServlet.do?textfield=
这个样子.

Answer 2

localhost:8080/PatientCase 提交后台自动会加上。
id换成textfield 有点奇怪
你直接把 action写在form中试试

Answer 3

你的意思是结果的URL里少了id=xxxx对吧应该是你form里面有个<input type="text" name="textfield" />
用get方法的提交时候，你给的action里面的?后面那段id=xxx会被忽略，
然后待提交的数据里面却有一个textfield文本框，值是空的，
于是URL就变成那样了。解决方案：
要么把method改成post，要么在form里加个隐藏的表单项name="id"，
<input type="hidden" id="the_hidden_id" name="id" />在提交的时候为它填入需要的值：
var the_hidden_id = document.getElementById('hidden_id');
the_hidden_id.value = id;这样提交后URL就形如
http://localhost:8080/PatientCase/servlet/ManagerServlet.do?id=xxx&textfield=

Answer 4

总而言之，就是GET方法提交时你给的action的问号后面的查询字符串会被忽略掉。

Answer 5

但是还有一个奇怪的就是，如果我把FORM放在不包含那个TEXT的地方的时候,还是会把后面的全部忽略是为什么?

Answer 6

只要用GET方法就会的吧，
这跟form里有多少要提交的数据没关系。如果你一定要用GET方法，就用我前面添加input type="hidden"的方法来提交你本来写在action中的?id=...这部分。
不然就用POST方法提交，更简单一点。
