我做时，都是返回字符窜，或者是xml，传入参数也是。 showModalDialog Method--------------------------------------------------------------------------------Creates a modal dialog box that displays the specified HTML document.SyntaxvReturnValue = window.showModalDialog(sURL [, vArguments][, sFeatures])ParameterssURL Required. String that specifies the URL of the document to load and display. vArguments Optional. Variant that specifies the arguments to use when displaying the document. Use this parameter to pass a value of any type, including an array of values. The dialog box can extract the values passed by the caller from the dialogArguments property of the window object. sFeatures Optional. String that specifies the window ornaments for the dialog box, using one or more of the following semicolon-delimited values: dialogHeight:iHeight Sets the height of the dialog window (see Res for default unit of measure). dialogLeft:iXPos Sets the left position of the dialog window relative to the upper-left corner of the desktop. dialogTop:iYPos Sets the top position of the dialog window relative to the upper-left corner of the desktop. dialogWidth:iWidth Sets the width of the dialog window (see Res for default unit of measure). center:{ yes | no | 1 | 0 } Specifies whether to center the dialog window within the desktop. The default is yes. help:{ yes | no | 1 | 0 } Specifies whether the dialog window displays the context-sensitive Help icon. The default is yes. resizable:{ yes | no | 1 | 0 } Specifies whether the dialog window has set dimensions. The default for both trusted and untrusted dialog windows is no. status:{ yes | no | 1 | 0 } Specifies whether the dialog window displays a status bar. The default is yes for untrusted dialog windows and no for trusted dialog windows. Return ValueVariant. Returns the value of the returnValue property as set by the window of the document specified in sURL.

但是你可以把main中的obj传入child.htm
在child.htm中进行判断传回

试了一下 ttyp(愿赌服输)的方法，child.htm返回的rtnTB.document.all("childTB").rows.length显示为'0',而主窗口传给子窗口的表格却能正确取出长度，大侠们帮研究一下该怎么改。

那我刚才的例子来说吧，我在child.htm所收到的主窗口的mainTB行数显示为1，这个是正常的。
而子窗口传给主窗口的childTB在主窗口中就变成了0，应该是3。
