例如....我的页面是...
I have a html page... I want to
1. get XML of all controls of that page
2. fill data from generated xml to all controls of that page.
I want to perform this operation using HTML and scripting language... also I want a generalize function which create XML for any form or inject any XML to controls of form..
For Example.... my page is...
<html xmlns="http://www.w3.org/1999/xhtml">

<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>Name</td>
<td>
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>Gender</td>
<td>
<asp:RadioButtonList ID="rblGender" runat="server">
<asp:ListItem>Male</asp:ListItem>
<asp:ListItem>Female</asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
<tr>
<td>Hobbies</td>
<td>
<asp:CheckBoxList ID="chkHobbies" runat="server">
<asp:ListItem>Facebook</asp:ListItem>
<asp:ListItem>Whats app</asp:ListItem>
<asp:ListItem>Skype</asp:ListItem>
<asp:ListItem>Chat Messanger</asp:ListItem>

</asp:CheckBoxList>
</td>
</tr>
<tr>
<td>Exp.</td>

<asp:DropDownList ID="ddlExp" runat="server">
<asp:ListItem><1 year</asp:ListItem>
<asp:ListItem>1-2 year</asp:ListItem>
<asp:ListItem>2-5 year</asp:ListItem>
<asp:ListItem>5-10 year</asp:ListItem>
<asp:ListItem></asp:ListItem>
</asp:DropDownList>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnBlankXML" runat="server" Text="Get Blank XML"
onclick="btnBlankXML_Click" />
</td>
<td><asp:Button ID="btnXMLWithData" runat="server" Text="XML with data"
onclick="btnXMLWithData_Click" /></td>
</tr>
</table>
label stRT
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
LABEL END
</div>
</form>
</body>
</html>
预期的XML应该是....
Expected XML should be....

<txtName>Test Data</txtName>
<rblGender>0</rblGender>
<chkHobbies>1,3,5</chkHobbies>
<ddlExp>2</ddlExp>
<btnBlankXML />

推荐答案
嘿，您可以使用以下函数生成xml for控制。在下面的代码中，我在新窗口中显示了xml。您可以根据需要修改代码以使用该xml。我没有在xml标签中添加值，因为你没有提到有关值的详细信息。
Hey you can use below function to Generate xml for controls. In the below code I have displayed xml in new window . You can modify the code to make use of that xml however you want. I haven't added values in the xml tags as in question you haven't mentioned about values in details.
function displayFormData() {
NewWindow = open("", "window2")
NewWindow.document.open("text/plain")
var i = 0;
var j = 0;
var x = "";
for (i = 0; i < document.forms.length; ++i) {
x = "<" + document.forms[i].id + ">";
for (j = 0; j < document.forms[i].elements.length; ++j) {
x = x + "<" + document.forms[i].elements[j].id + ">";
x = x + "</" + document.forms[i].elements[j].id + ">";
}
x = x + "</" + document.forms[i].id + ">";
NewWindow.document.write(x);
}
NewWindow.document.close()
return false
}
