On the window. showModalDialog window page, use window. returnValue to set the return value;
For example, window. returnValue = 'refresh ';

B. When writing window. showModalDialog window function, define a variable and operate the parent window according to the variable value;
Example: varwinPar = window. showModalDialog (urls, 'erpwindows', 'dialogwidth = '+ widths + 'px; dialogHeight =' + heigths + 'px; status = no; center = yes; scroll = no ');
If (winPar = "refresh ")
Window. location. reload (); // executed when the window. showModalDialog window is closed
