[置顶] HTML子窗体传值父窗体的几种方式

第一种：Open

   1. 通过Opener方法调用父窗体方法传值
       

 1 < html >
 2 < head >
 3 < meta  http-equiv ="Content-Type"  content ="text/html; charset=gb2312" >
 4 < title > 父窗体 </ title >
 5 </ head >
 6 < body >
 7 < form  name ="form1"    method ='get' >
 8 < input  type =text  name ='txtvalue'  value ='' >
 9 < input  type ='button'  onclick ='openWindow()'   value ="弹出" >
10 </ form >
11 < script  type ="text/javascript" >  
12       function  openWindow()  {
13         window.open(子窗体.html ' , ' newWindow ' , ' height = 300 ,width = 300 ,scrollbars = auto ' );       
14      } 
15      function setValue(returnValue) {
16           document.getElementById( ' txtvalue ' ).value=  returnValue;
17      }
18 </script> 
19
20 </body>
21 </html> 

   

 1 < html >
 2 < head >
 3 < meta  http-equiv ="Content-Type"  content ="text/html; charset=gb2312" >
 4 < title > 子窗口 </ title >
 5    < script  type ="text/javascript" >
 6
 7         function  valueExit()  {
 8             var  returnValue  =   docment.getElementById( ' txtValue ' ).value;
 9            opener.setValue(returnValue);                  
10            window.close();
11        }
12    </ script >
13 </ head >
14 < body >
15 < h1  align ='center' > 子窗口! </ h1 >< hr >
16 < div  align ='center' >
17 < form  name ="fz"  action ='#'  method ='get' >
18 < input  type =text  name ='txtValue'  id ='txtValue' >
19 < input  type ='button'  value ='关闭'  onclick ='valueExit()' />  
20 </ form >
21 </ div >
22 </ body >
23 </ html >

   2.在子窗体里面用window.opener.document.from方法传值

     

 1 < html >
 2 < head >
 3 < meta  http-equiv ="Content-Type"  content ="text/html; charset=gb2312" >
 4 < title > 父窗体 </ title >
 5 </ head >
 6 < body >
 7 < form  name ="f1"  action ='#'  method ='get' >
 8 < input  type =text  name ='ft'  value ='' >
 9 < input  type ='button'  onclick ='openWindow()'   value ="弹出" />
10 </ form >
11 < script  type ="text/javascript" >  
12 <!--  
13 function  openWindow()  {
14      newWindow  =  window.open( ' z1.html ' , ' newWindow ' , ' height=300,width=300,scrollbars=auto ' );       
15       if  (newWindow  !=   null )      {
16              newWindow.focus();     
17       }  
18 }
19 // --> 
20 </ script >  
21 </ select >
22 </ body >
23 </ html >  

  

 1 < html >
 2 < head >
 3 < meta  http-equiv ="Content-Type"  content ="text/html; charset=gb2312" >
 4 < title > 子窗口 </ title >
 5 </ head >
 6 < body >
 7 < h1  align ='center' >  子窗口! </ h1 >< hr >
 8 < div  align ='center' >
 9 < form  name ="fz"  action ='#'  method ='get' >
10 < input  type =text  name ='tt' >
11 < input  type ='button'  value ='关闭'  onclick ='window.opener.document.f1.ft.value=document.fz.tt.value; self.close();'  />
12 </ form >
13 </ div >
14 </ body >
15 </ html >

      
    扩展：子窗体关闭要刷新父窗体，在子窗体赋值的第一句加上opener.location= opener.location.href;

第二种：ShowModalDialog

    1.window.returnValue方法传值

      

 1 < html >
 2 < head >
 3 < script  type ="text/javascript" >  
        function fnOpen() {
 4      var  returnTarget  =  window.showModalDialog( "zichuangti. aspx " ,  ' newWindow ' ,  ' dialogHeight=500px;dialogWidth=700px;center=yes;resizable=yes;help=no; ' );
 5               if  (returnTarget  !=  undefined  &&  returnTarget.length  >   0 )          }
 8   </ script >
 9 </ head >
10 < body >
11      < form  id ="form1"  runat ="server" >
12          < div >
13             传过来的值:  < input  type ="text"  id ="oArgs"  runat  ="server" />
14              < input  id ="button"  name ="button"  type ="button"  value ="打开窗口"  runat  ="server"  onclick ="fnOpen()"/ >
15          </ div >
16      </ form >
17
18 </ body >
19 </ html >
20
21
22

< html >
< head >
< script  type ="text/javascript" >      
     function  exit() 
    {
        window.returnValue  =  form1.txtreturn.value;  // 返回值
         window.close();
    }
     </ script >
</ head >
< body >
     < form  id ="form1"  runat ="server" >
         < div >
            传递过来的值:  < input  type ="text"  id ="txtreturn"  runat  ="server" />
             < input  id ="button"  name ="button"  type ="button"  value ="关闭窗口"  runat  ="server"  onclick ="exit()" />
         </ div >
     </ form >
</ body >
</ html >
