我正在尝试将 Javascript 隐藏字段中的数据插入 XML,但是只有“null”出现。我已经声明了变量,但它似乎无法捕获隐藏字段。我束手无策,希望我的问题能得到解决。
**<<-----I use session to pass the value to the XML page----->>**
<%
String X = (String)session.getAttribute("X");
String Y = (String)session.getAttribute("Y");
String W = (String)session.getAttribute("W");
String H = (String)session.getAttribute("H");
session.setAttribute("X",X);
session.setAttribute("Y",Y);
session.setAttribute("W",W);
session.setAttribute("H",H);
%>
**<<------Snippet of Javascript codes------->>**
function moveIt(){
if (!moveEnabled||!MovableItem) return;
// display info during testing
X = MovableItem.offsetLeft;
Y = MovableItem.offsetTop;
W = MovableItem.offsetWidth;
H = MovableItem.offsetHeight;
==Some codes here==
document.getElementById('X').value = X;
document.getElementById('Y').value = Y;
document.getElementById('W').value = W;
document.getElementById('H').value = H;
}
**<<-----JSP codes that I need to pass the values onto an XML----->>**
<form name='form1' action='UpdateXML.jsp' method='post'>
<input type='hidden' name=source value="<%=src%>" />
<input type='hidden' id="X" name="X" value="<%=X%>"/>
<input type='hidden' id="Y" name="Y" value="<%=Y%>"/>
<input type='hidden' id="W" name="W" value="<%=W%>"/>
<input type='hidden' id="H" name="H" value="<%=H%>"/>
<button type="button" onclick="window.location.href='editcompany.jsp'">Back!</button>
<button type="submit">Insert Into XML!</button>
</form>
我需要将隐藏字段(数据)插入 XML。我试过了,但它显示为“空”。有没有人可以帮我解决这个问题?非常感谢!
