iframe 父窗口和子窗口相互的调用方法集锦,需要的朋友可以参考下。
一、父窗口调用iframe子窗口方法 1、HTML语法:&iframe name="myFrame" src="child.html"&&/iframe& 2、父窗口调用子窗口:myFrame.window.functionName(); 3、子窗品调用父窗口:parent.functionName(); 简单地说,也就是在子窗口中调用的变量或函数前加个parent.就行 4、父窗口页面源码:
代码如下: &html& &head& &script type="text/javascript"& function say() { alert("parent.html------&I'm at parent.html"); } function callChild() { //document.frames("myFrame").f1(); myFrame.window.say(); } &/script& &/head& &body& &input type=button value="调用child.html中的函数say()" onclick="callChild()"& &iframe name="myFrame" src="child.html"&&/iframe& &/body& &/html&
5、子窗口页面:
代码如下: &html& &head& &script type="text/javascript"& function say() { alert("child.html---&I'm at child.html"); } function callParent() { parent.say(); } &/script& &/head& &body& &input type=button value="调用parent.html中的say()函数" onclick="callParent()"& &/body& &/html&
二、iframe 父窗口和子窗口相互的调用方法 1、IE中使用方法: 父窗口调用子窗口:iframe_ID.iframe_document_object.object_attribute = attribute_value 例子:onClick="iframe_text.myH1.innerText='';" 子窗口调用父窗口:parent.parent_document_object.object_attribute = attribute_value 例子:onclick="parent.myH1.innerText='';" 2、Firefox中使用方法: 上面在IE下没有问题,但在firefox下不正常。在firefox下,应该是如下调用方法: 父窗口调用子窗口:window.frames["iframe_ID"].document.getElementById("iframe_document_object"&).object_attribute = attribute_value 例: window.frames["iframe_text"].document.getElementById("myH1").innerHTML= "http://hi.jb51.net"; 子窗口调用父窗口:parent.document.getElementById("parent_document_object").object_attribute = attribute_value 例: parent.document.getElementById("myH1").innerHTML = "http://jb51.net"; 3、完整的例子 test.htm
代码如下: &HTML& &HEAD& &TITLE& Test Page &/TITLE& &script src="prototype-1.4.0.js"&&/script& &script language="javascript"& function show() { window.frames["iframe_text"].document.getElementById("myH1").innerHTML = "http://hi.jb51.net"; } &/script& &/HEAD& &BODY& &iframe height="350" width="600" src="iframe_test.htm" name="iframe_text"&&/iframe& &form action="" method="post"& &input name="haha" id="haha" type="text" maxlength="30" value="haha" /& &br /& &textarea cols="50" rows="5" id="getAttributeMethod"&&/textarea& &input type="button" onClick="show();" value="提交"/& &/form& &h1 id="myH1"&d&/h1& &/BODY& &/HTML&
frame_test.htm
代码如下: &!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"& &html xmlns="http://www.w3.org/1999/xhtml"& &head& &meta http-equiv="Content-Type" content="text/ charset=gb2312" /& &title&无标题文档&/title& &/head& &script language="javascript"& function show() { parent.document.getElementById("myH1").innerHTML = http://jb51. } &/script& &body& &h1 id="myH1"&ha&/h1& &form action="" method="post"& &input name="abc" id="abc" type="text" maxlength="30" value="abc" /& &br /& &textarea cols="50" rows="10" id="text"&&/textarea& &br /& &input type="button" value="提交" onclick="show();"/& &/form& &/body& &/html&
test.htm里面firefox下访问iframe 必须用name,不能用id,所以要改为name="iframe_test" 。(http://chenling1018./blog/static//) 三、在c#中如何动态改变iframe的src值,动态指向一个网页 1)如果是javascript脚本 给iframe加一个ID如&iframe id=frmList…… 在脚本写 frmList.document.location=strNewUrl 2)如果是后台程序 给iframe加一个ID,再加上runat=server 如&iframe id=frmList runat=server …… 在程序里写 frmList.Attributes.Add("src",strNewUrl);

Resolved ordinal import.
Resolved dynamic C import (similar images also exist for C++ and ordinal functions).
The parent module of this module called the GetProcAddress function to dynamically get the address of this function.
This does not necessarily mean the parent module actually used the function address to call the function.
Unresolved C function (similar images also exist for C++ and ordinal functions).
This function is called by the parent module, but it is not exported from the current module.
This is often referred to as an "unresolved external function".
If this module is an implicit or forwarded dependency, then the parent module will fail to load.
If this module is a delay-load dependency, then the parent module will most likely recover from the missing dependency, as that is a feature of using delay-load dependencies.
Unresolved dynamic C function (similar images also exist for C++ and ordinal functions).
The parent module of this module called the GetProcAddress function to dynamically get the address of this function, but the current module does not export the function.
This is not necessarily an error since one of the reasons modules call GetProcAddress is to see if a function exists in a module.
The Parent Import Function View is comprised of five columns:
See the above list for descriptions.
The header for this column has the letters "PI" in it, which just stands for "Parent Imports"
The ordinal value of the imported function, if the function is imported by ordinal.
This value can be "N/A" if the function is imported by name.
The hint value for the imported function.
The hint value is used internally by the operating system's loader to quickly match imports with exports.
It is used as an index into the array of exported functions in the selected module.
The name of the imported function, if the function is imported by name.
This can be "N/A" if the function is imported by ordinal.
C++ functions can be viewed in their native decorated form or in a human readable undecorated form.
for more information.
You may also see "&invalid string&" as a function name, which means a call to GetProcAddress was made with an invalid string, or "&empty-string&", which means GetProcAddress was called with an empty string.
Entry Point
The entry point memory address for the function.
For implicit and forward dependencies, this field often reads "Not Bound", which means that the entry point address will not be known until load time.
If an address is given, then the parent module has been pre-bound by a program like BIND.
Binding is the process of walking the import list of a module and the export list of all its dependent modules, in order to fill in the import list with the absolute addresses to the functions it references.
This job is usually done by the loader as each module is loaded, but can be skipped if the modules have been pre-bound.
Pre-binding is an optimization that calculates the absolute addresses based off of the modules' preferred base addresses and stores them in the module's import table.
Assuming a dependency of a given module actually loads at its preferred base address and has not changed, then the loader can save time by skipping the bind phase to that dependency module.
For dynamic dependencies, this Entry Point field displays the address returned by the GetProcAddress function call.
The function list can be sorted on the data in any column in the list.
Simply click on the column header button for the column you wish to sort by.
An arrow (^) is displayed in the column header for the column that the list is currently sorted by.
You can also size a column to its "best fit" width by double-clicking the divider line between two columns in the column header.
You can search for text in the currently sorted column by simply typing in the first few characters of the item you wish to find.
For ordinal and hint values, you may enter decimal or hex (prefaced by 0x) values to search for.虚函数有什么作用_百度知道

I am trying to call a javascript function defined in a parent from a child window.
I have two files like this:
&title&Test&/title&
&script type="text/javascript"&
function foo () {
alert ("Hello from parent!");
function doStuff () {
var w = window.open("testa.html");
&input type="button" value="open" onClick="doStuff();" /&
And child:
&title&Test A&/title&
&script type="text/javascript"&
function get() {
window.opener.foo();
&input type="button" value="Call Parent" onClick="get();" /&
I can not, for the life of me, call the function foo from the child process.
I thought this should be possible with the window.opener object, but I can not seem to make this work.
Any suggestions?
Ensure you are accessing this via http:// so the Same origin policy passes and you can access opener from the child. It won't work if you're just using file://.
