树-----------------------------------------------------------------

Question

两种方法:一种是: t.php 
<?php
  echo 'document.writeln(\'tree.nodes["'.$id.'"] = "'.$values.';'.$values.'"\');';
?>二是:
t.php
<script >
window.tree = new MzTreeView("tree");    tree.icons["property"] = "property.gif";
    tree.icons["css"] = "collection.gif";
    tree.icons["book"]  = "book.gif";
    tree.iconsExpand["book"] = "bookopen.gif"; //展开时对应的图片
    tree.setIconPath("images/"); //可用相对路径，留空为当前路径
    //[color=#FF0000]tree.nodes["320_324"] = "text:事件; icon:css; data:id=324"; 
  tree.nodes[<?php echo $id;?>] = "<?php echo $value1.";".$value2; ?>";</script>

Answer 1

while($rs=mysql_fetch_object($re2)){
?>

tree.nodes[<? echo $rs->id?>]="text:<? echo $rs->text?>;url:<? echo $rs->url?>;";
<?
}
?>运行，查看页面源代码后，报这个错 missing ] in index expression
tree.nodes[-1_1]="text:Online Help;url:gamebd_edit.php?id=1;"这一行报错
 tree.nodes[3_4]="text:系统概述;url:gamebd_edit.php?id=7;"
跟下面能显示正确的树是一样的啊 tree.nodes["-1_1"] = "text:Online Help;url:tree_edit.asp?id=1;"
 tree.nodes["3_4"] = "text:系统概述;url:tree_edit.asp?id=4;"
