dwr增加行DWRUtil.addRows

我现在用dwr做增加行的例子。现在得到一个list然后遍历根据list的length来添加。现在的问题是当list.length的值是1的时候是增加了一行。当值是2的时候问题就出现了。是加了4行同样的加了2行。3的时候是6行了同样的加了3行。不知道是不是DWRUtil.addRows的问题啊。 :cry:
[b]问题补充：[/b]
代码
[code="java"]
<br> function addrow(sysid)<br> {<br><br> DWRUtil.removeAllRows(&quot;imgtable&quot;);<br> DwrUtils.queryFileName(sysid,backFunction);<br> }</p> <pre><code> function backFunction(data) { for(var i=0;i&lt;data.length;i++) { var name=data[i].fileName; DWRUtil.addRows(&quot;imgtable&quot;,data,[function(data){return name}]); } } &lt;/script&gt; </code></pre> <p>[/code]</p>

官方不是有遍历的例子吗?为什么不参考呢?我看你的写法和官方的差别很大

问题出在你代码,你那个var只赋值了一次.

/**

  dwr.util.addRows = function(ele, data, cellFuncs, options) {
  ele = dwr.util._getElementById(ele, "addRows()");
  if (ele == null) return;
  if (!dwr.util._isHTMLElement(ele, ["table", "tbody", "thead", "tfoot"])) {
  dwr.util._debug("addRows() can only be used with table, tbody, thead and tfoot elements. Attempt to use: " + dwr.util._detailedTypeOf(ele));
  return;
  }
  if (!options) options = {};
  if (!options.rowCreator) options.rowCreator = dwr.util._defaultRowCreator;

  if (dwr.util._isArray(data)) {
  for (rowNum = 0; rowNum < data.length; rowNum++) {
  options.rowData = data[rowNum];
  options.rowIndex = rowNum;
  options.rowNum = rowNum;
  options.data = null;
  options.cellNum = -1;
  tr = dwr.util._addRowInner(cellFuncs, options);
  if (tr != null) ele.appendChild(tr);
  }
  }
  else if (typeof data == "object") {
  rowNum = 0;
  for (var rowIndex in data) {
  options.rowData = data[rowIndex];
  options.rowIndex = rowIndex;
  options.rowNum = rowNum;
  options.data = null;
  options.cellNum = -1;
  tr = dwr.util._addRowInner(cellFuncs, options);
  if (tr != null) ele.appendChild(tr);
  rowNum++;
  }
  }

  dwr.util.highlight(ele, options);
  };
