JSP passes multiple parameters using a URL __jsp

Using Java statements in C # to pass multiple parameters using URLs,

Original statement: String str = ' <script language= ' JavaScript ' >window.showmodaldialog (' xmjl_editor.aspx?id= ' + Txt_nodeid. Text + "& xmjl_id=" + GRID_XMJL. Datakeys[e.rowindex]. Value.tostring () + "', ' string t ', ' scroll=yes;status=0;help=0;resizable=1;height=400px;width=800px ') </script > ";

But how also pass the parameter, later from the Internet search, also did not find a practical method, later an unintentional operation resolved the problem, modify the following:

String str = "<script language= ' JavaScript ' >window.showmodaldialog (' xmjl_editor.aspx?id= ' + Txt_nodeid.) Text + "&xmjl_id=" + GRID_XMJL. Datakeys[e.rowindex]. Value.tostring () + "', ' string t ', ' scroll=yes;status=0;help=0;resizable=1;height=400px;width=800px ') </script > ";

Other places have not changed, the main is "& xmjl_id" changed to "&xmjl_id", remove the connection symbol after the space is correct.

A small problem, toss me for a long time, programming no small things.
