关于如何获取ifamge中的html 控件image的onclick事件？急。在线等，马上给分

Question

小弟现在做一个网页，其中html是别人写的，现在我把html嵌入我的网页中，用iframe.但是问题来了，我无法获取 iframe中的image控件的单击事件。
代码如下：<form id= "loginform" action="home.html" onsubmit="return login_form(this);" method="get">                            
    <table width="450" border="0" cellspacing="0" cellpadding="0">
     <tr>
       <td width="164" rowspan="2" align="center" valign="middle">
        <Input name="Submit" type="image" value="Submit" src="images/login_33.jpg" width="119" height="59" border="0"> 
        </td>
      </tr>
</table>父页面的JS
document.frames("iframe1").document.getElementById("submit").onclick =  test();这样行不通的，请教各位该怎么弄呀？

Answer 1

document.frames["iframe1"].document.getElementById("submit").onclick = test;

Answer 2

getElementById("submit"),
好像没有这个id吧，你在submit里定义一个相应id
<input id=”submit" type="image" value="Submit" src="images/login_33.jpg" width="119" height="59" border="0">  
这个试一试；

Answer 3

不行哦
消息: 'document.frames.iframe2.document.getElementById(...)' 为空或不是对象

Answer 4

document.frames["iframe1"].document.getElementsByName("Submit")[0].onclick = test;
这样试试~·

Answer 5

可以了。谢谢了。马上给分。
再请教个问题。
为什么我写的ajax没有用呢。可以指点一下吗？
function test1()
        {
            
            var uname;
            var upwd;
            uname = document.frames("iframe2").document.getElementById("email").value;
            upwd = document.frames("iframe2").document.getElementById("password").value;
            alert("a");
            try 
            { 
                alert("b");
                xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); 
            } 
            catch (e) 
            { 
                alert("c");
                try 
                { 
                    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
                } 
                catch (e) 
                {  
                    try 
                    { 
                        xmlhttp=new XMLHttpRequest(); 
                    } 
                    catch (e) 
                    { 
                    } 
                } 
             }  
            var url =  "/login_lod.aspx?name="+uname+"&pwd="+upwd;
            alert(url);
            xmlHttp.open("GET",url, true);              
            xmlhttp.onreadystatechange=function() 
              { 
                alert("e");
                if(4==xmlhttp.readyState) 
                { 
                    if(200==xmlhttp.status) 
                    { 
                        if (xmlhttp.responseText=="yes") 
                        {  
                           alert("1"); 
                        } 
                        else 
                        { 
                            alert("2"); 
                            alert("你输入的用户名或密码不正确，请重新输入！");
                           
                        }  
                    } 
                    else 
                    { 
                      alert("3");
                    } 
//                    var ch=document.getElementById("check1"); 
//                  ch.innerHTML=msg;  
                } 
              } 
           
        }我测试了一下。只弹出到URL，没有进到onreadystatechange的function里。这是怎么回事呀？

Answer 6

function test1()
        {
            
            var uname;
            var upwd;
            uname = document.frames("iframe2").document.getElementById("email").value;
            upwd = document.frames("iframe2").document.getElementById("password").value;
            alert("a");
            try 
            { 
                alert("b");
                xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); 
            } 
            catch (e) 
            { 
                alert("c");
                try 
                { 
                    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
                } 
                catch (e) 
                {  
                    try 
                    { 
                        xmlhttp=new XMLHttpRequest(); 
                    } 
                    catch (e) 
                    { 
                    } 
                } 
             }  
            var url =  "http:/localhost/login_ajax.aspx?name="+uname+"&pwd="+upwd;
            alert(url);
            xmlHttp.open("GET",url, true);              
            xmlhttp.onreadystatechange=function() 
              { 
                alert("e");
                if(4==xmlhttp.readyState) 
                { 
                    if(200==xmlhttp.status) 
                    { 
                        if (xmlhttp.responseText=="yes") 
                        {  
                           alert("1"); 
                        } 
                        else 
                        { 
                            alert("2"); 
                            alert("你输入的用户名或密码不正确，请重新输入！");
                           
                        }  
                    } 
                    else 
                    { 
                      alert("3");
                    } 
//                    var ch=document.getElementById("check1"); 
//                  ch.innerHTML=msg;  
                } 
              } 
           
        }
只弹出到alert(url);这里。后面就没有继续下去了。
