无法在Chrome中访问其他框架的内容 [英] Can't access content of another frame in Chrome
问题描述
第一帧需要访问第二帧中的元素frame(xsample),当它完全加载并且任何onload JS函数完成时。
< frameset cols =*,*rows =*border =0framespacing =0>
< frame src =picker.aspname =xpickerframeborder =nomarginwidth =15marginheight =15>
< frame src =doc.aspname =xsampleframeborder =nomarginwidth =15marginheight =15>
< / frameset>
以下代码适用于IE和Firefox,但不适用于Chrome或Safari,在 parent.xsample
始终为false
function startWork(){
if isSurveyLoaded()== false){
SL = setTimeout(startWork(),1000);
return;
}
else {
setTimeout(doMoreWork(),2000);
函数isSurveyLoaded(){
if(!parent.xsample){
return false;
}
if(!parent.xsample.self.name){
return false;
if(parent.xsample.document.readyState!='complete'){
return false;
}
else {
return true;
}
}
parent.frames [xsample]
来访问框架。
隐式引用全局
对象上的命名元素不是标准化的。
在另一个笔记中,千万不要做 setTimeout(doMoreWork(),1000)
使用eval来执行代码。
使用 setTimeout(doMoreWork,1000)
这是正确的方式来做到这一点。
I have two frames. The pages in both frames come from the same domain (either localhost or a live domain - both using the same protocol).
The first frame needs to access elements of the second frame (xsample) when it's fully loaded and any onload JS functions have completed. But the second frame takes a while to load.
<frameset cols="*,*" rows="*" border="0" framespacing="0">
<frame src="picker.asp" name="xpicker" frameborder="no" marginwidth="15" marginheight="15">
<frame src="doc.asp" name="xsample" frameborder="no" marginwidth="15" marginheight="15">
</frameset>
The code below works in IE and Firefox but not in Chrome or Safari, In those parent.xsample
is always false
function startWork(){
if(isSurveyLoaded()==false){
SL=setTimeout("startWork()",1000);
return;
}
else{
setTimeout("doMoreWork()",2000);
}
}
function isSurveyLoaded(){
if(!parent.xsample){
return false;
}
if(!parent.xsample.self.name){
return false;
}
if(parent.xsample.document.readyState!='complete'){
return false;
}
else{
return true;
}
}
Use parent.frames["xsample"]
to access the frame.
Implicit references to named elements on the global
object is not standardized.
On a different note, never do setTimeout("doMoreWork(), 1000)"
as this forces the VM to use eval to execute the code.
Use setTimeout(doMoreWork, 1000)
which is the proper way to do it.
