树的点击　　最后两句显示没有这个方法　改人的不懂

// 树的点击
function zTreeOnClick(event, treeId, treeNode) {
// showCurrentFolder(treeNode);
/*
* if (treeNode.name == taskManagerNodeName) { $("#ifr").attr("src",
* taskManagerUrl); document.getElementById("ifr").src = taskManagerUrl;
* return; }
*/
if(treeNode.name == taskManagerNodeName){
var iframe = document.createElement("iframe");
iframe.src = taskManagerUrl;
if (iframe.attachEvent) {
iframe.attachEvent("onload", function() {
alert("Local iframe is now loaded.");
});
} else {
iframe.onload = function() {
alert("Local iframe is now loaded.");
}
}
$("#rightContent").html(iframe);
return;
}
/*document.getElementById("ifr").contentWindow.showCurrentFolder(zTreeObj,
treeNode);
document.getElementById("ifr").contentWindow._pageRefurbish(treeNode.id);*/

var iframe = document.createElement("iframe");
var iframe=$('<iframe id="ifr" name="ifr" width="100%" height="100%" frameborder="0" > </iframe>');
iframe.src = docUrl;
if (iframe.attachEvent) {
iframe.attachEvent("onload", function() {
alert("Local iframe is now loaded.");
});
} else {
iframe.onload = function() {
alert("Local iframe is now loaded.");
}
}
// $("#rightContent").html(iframe);
// return;

$("#rightContent").html(iframe);
  document.getElementById("ifr").contentWindow.showCurrentFolder(zTreeObj, treeNode);
  document.getElementById("ifr").contentWindow._pageRefurbish(treeNode.id);
 
}

树的点击 用得着这么多代码么，，，，，一行应该就够了吧 如果配合好css
