从IFRAME到父母的价值。 [英] PASSING VALUE FROM IFRAME TO PARENT.
问题描述
Sorrryy提出这样的基本问题，但我确实需要你的帮助！这是'/ b $ b我正在尝试做什么：
在我的父表单中，我正在调用我的iframe表单以获得一定的价值，
然后取决于该值启用或禁用我的
父表单中的提交按钮，而不使用我的
表单中的任何刷新/重新加载或提交按钮。
看起来很简单，但我不知道如何让它工作。实际上，我已经能够在我的父母中使用来自
我的iframe的值填充列表框，文本框。但我无法启用或禁用此按钮。任何人都可以
告诉我该怎么做请

请参阅下面的示例;但是，我怀疑你的努力不是值得他们引起的问题，对于用户而言，确实是微不足道的，只需
停用javascript或修改脚本在run-rime让它按照他/她想要的方式工作;-)
< script type =" text / javascript">
var someHTML ="< script type = \" text \ / javascript \">" +
" function foo（）{" +
" var bReturn = Math.random（）< 0.5;" +
" document.body.innerHTML =''禁用？ - > ''+ bReturn;" +
"返回bReturn; };" +
"< \ / script>" +
" Hello，World！" ;;
var bar = function（）{
var oldHandler，falseHandler = new Function（" return false"）;
var oldAction，falseAction ="＃" ;;
返回函数（frm）{
var fr = frames [" myIframe"];
if（！oldHandler）oldHandler = frm.onsubmit ;
if（！oldAction）oldAction = frm.action;
if（fr&& fr.foo）{
if（ fr.foo（））{
frm.onsubmit = falseHandler;
frm.action = falseAction;
frm.elements [" mySubmitButton" ;] .disable = true;
} else {
frm.onsubmit = oldHandler;
frm.action = oldAction;
frm.elements [" mySubmitButton"]。disabled = false;
}
}
}
}（）;
< / script>
< form action =" foo.html" onsubmit =" return confirm（''真的？''）">

< input type =" submit" name =" mySubmitButton">

< / form>
< iframe name =" myIframe" src =" javascript ：parent.someHTML">< / iframe>
See below for an example; however, I suspect that your efforts are not
worth the issues they''ll cause, it''s indeed trivial for a user to just
deactivate javascript or modify script at run-rime to have it work the

var bar=function(){

<iframe name="myIframe" src="javascript:parent.someHTML"></iframe>
hummm ...首先感谢Yann-Erwan ！谢谢你的快速回答
，但正如你说的那么简单的努力......加上我会
必须提交表格....好吧，我真的希望以我父母的形式做这样的事情是一种
方式：
函数EnableDisableButton（）
{
var fr = frames [''myIframe'']。document.forms [0];
if（fr [" MyIframeValue"。。value）
{
document.forms [0] .elements [" EnableDisable"]。disabled = false;
}
}
并在我的父表单中引用这样的myiframe：
< IFRAME id =" ; myIframe" onload =" EnableDisableButton（）"
SRC =" MyIFrame.asp">
< / IFRAME>
然后：
< form name =" ParentForm">
< br>
< INPUT TYPE =提交已停用VALUE =" ;启用/禁用id = EnableDisable
name = EnableDisable>
但这不起作用....任何想法??
再次感谢！

hummm...first of all thanks Yann-Erwan!! thanks for your quick answer
but as you said too much effort for something that simple...Plus i''ll
have to submit the form....Well, i was realy hoping that it could be a
way to do something like this in my parent form:
function EnableDisableButton()
{
var fr=frames[''myIframe''].document.forms[0];
if(fr["MyIframeValue"].value)
{
document.forms[0].elements["EnableDisable"].disabled=false;
}
}
and refer to myiframe like this in my parent form:
<IFRAME id="myIframe" onload="EnableDisableButton()"
SRC="MyIFrame.asp">
</IFRAME>
and then :
<form name="ParentForm">
<br>
<INPUT TYPE=submit disabled VALUE="Enable/Disable"id=EnableDisable
name=EnableDisable>
But this doesn''t work....any idea??
Thanks once again!

您的方法似乎很好，我已经让它在我的IE6 /离线上运行，请参阅
以下。你能告诉我更多关于你得到什么错误的信息，以及
平台/浏览器吗？
我还会添加一些物体检测以获得更好的效果后退，并给你的
iframe一个名称，以便能够从''frames''集合中引用它
正确。
- - fr1.html ---
< script type =" text / javascript">
function EnableDisableButton（）{
var fr = frames [''myIframe''];
if（fr&& fr.document）{
fr = fr.document.forms [0];
if（fr.elements [" MyIframeValue"]。value）{
document.forms [0] .elements [" EnableDisable"]。disabled = false;
}
}
}
< / script>
< form action =" foo">
< input type =" submit"
disabled =" disabled"
name =" EnableDisable">
< / form>
< ifra me name =" myIframe"
onload =" EnableDisableButton（）"
src =" fr2.html">< / iframe>
--- fr2.html ---
< form action =" foo">
< input type =" text"
name =" MyIframeValue"
value =" Hello，World！">
< / form>
问候，
是的。
Your approach seems fine and I''ve got it working on my IE6/offline, see
below. Could you tell me more about what error you get, and on which
platform/browser?
I''d also add some object detection for a better fallback and give your
iframe a name to be able to refer to it from the ''frames'' collection
correctly.
--- fr1.html ---
<script type="text/javascript">
function EnableDisableButton() {
var fr=frames[''myIframe''];
if(fr && fr.document){
fr=fr.document.forms[0];
if(fr.elements["MyIframeValue"].value) {
document.forms[0].elements["EnableDisable"].disabled=false;
}
}
}
</script>
<form action="foo">
<input type="submit"
disabled="disabled"
name="EnableDisable">
</form>
<iframe name="myIframe"
onload="EnableDisableButton()"
src="fr2.html"></iframe>
--- fr2.html ---
<form action="foo">
<input type="text"
name="MyIframeValue"
value="Hello, World!">
</form>
