本文實例講述了JS簡單實現父子窗口傳值功能。分享給大家供大家參考，具體如下：
父窗口頁面father.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD><TITLE>父窗口 </TITLE><script language="javascript"><!--function openChild(){var childwin = window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");if(childwin != null)document.getElementById("f11").value = childwin;}//--></script></HEAD><BODY><FONT face="宋體"></FONT><br>傳遞到父窗口的值:<input id="f9" type="text" value="我是父窗口的值，呵呵" name="txt9"><br><br>子窗口設置的值:<input id="f10" type="text" name="txt10"><br><br>子窗口關閉后返回的值:<input id="f11" type="text" name="txt11"><br><br><input id="Button1" onclick="openChild()" type="button" value="openChild" name="Button1"></BODY></HTML>子窗口頁面 child.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD><TITLE>彈出頁面（子窗口）</TITLE></HEAD><BODY><FONT face="宋體"></FONT><br>父窗口傳遞來的值:<input id="c0" type="text" name="txt0"><br><br><br>輸入要設置父窗口的值:<input id="c1" type="text" name="txt1"><input id="Button1" onclick="setFather()" type="button" value="不關閉本頁面，設置父窗口的值" name="Button1"><br><br><br>輸入返回的值:<input id="c2" type="text" name="txt2"><input id="Button2" onclick="retrunValue()" type="button" value="關閉本頁面,并返回值給父窗口" name="Button2"><script language="javascript"><!--var fatherwin=window.dialogArguments;//獲得父窗口傳遞來的值if(fatherwin!=null){document.getElementById("c0").value = fatherwin.document.getElementById("f9").value;}//設置父窗口的值function setFather(){fatherwin.document.getElementById("f10").value = document.getElementById("c1").value}//設置返回到父窗口的值function retrunValue(){var s = document.getElementById("c2").value;window.returnValue=s;window.close();}//--></script></BODY></HTML>希望本文所述對大家JavaScript程序設計有所幫助。
