我正在openui5中添加/删除面板部分容器。删除选定的面板容器时，我可以执行此操作。但删除容器并再次添加新容器后，我收到“添加重复ID为txn_1的元素”的错误。如何解决这个问题？
我使用以下代码：
var Iconadd = new sap.ui.commons.Button({ //add container code
text : "ADD",
width:"65px",
icon : "sap-icon://add",
press : function() {
var len=$('#panelcontainer .sapUiPanel').length;
//alert("len"+len);
Createnewtransaction(len+1);
//alert(""+len);
//var content=$("#panelcontainer").html();
//$("#panelcontainer").append(content);
//var length=$('#panelcontainer').length;
// alert(""+length);
}
});
Createnewtransaction(1);//onload defaultly one conatiner should show
function Createnewtransaction(len){ //panel code and delete container code
//alert("in"+len);
var oPanel3 = new sap.ui.commons.Panel("txn_"+len,{width: "100%", showCollapseIcon: false});
oPanel3.setAreaDesign(sap.ui.commons.enums.AreaDesign.Fill);
oPanel3.setBorderDesign(sap.ui.commons.enums.BorderDesign.None);

很明显你会遇到错误。 SAPUI5在jQuery之上提供了一个功能强大的API控件，包括DOM操作。如果我正确理解您的源代码，那么您自己就是在操纵DOM，但是您应该通过API来实现。请检查Panel的documentation，有一种安全删除内容的方法。并且请在将来提供格式良好的编码示例，这只是一团糟，只有很少人会帮助您度过这个烂摊子。
