Best phone camera 2016/2017: Galaxy S7 vs iPhone 7 vs Google Pixel vs HTC 10 Evo vs OnePlus 3T vs…
At my website I have a page that has three frames. One frame allows users to select a picture to be displayed in the third frame. They can select a picture without problem. But if I were to upload a new picture to replace it, the old picture (which does not even exist anymore) will still be shown. The "Refresh" button in IE just refreshes the main page, not the loading of the individual frame pages. Please help. click here
This (Ctrl F5) does solve the refresh problem for me. But I also want a webpage that refreshes the picture automatically. Unless I put a note on the webpage asking people to type Ctrl F5, their pictures will not change.
I need a global solution.
So, you are worried that your viewers may have your page cached in their browser history and any new page elements may not be displayed correctly ?
If that is the case can you confirm ?
You can also set some information in the page header to disallow page caching to begin with, meaning no matter how often someone visits your page they will display what is there, not what their browser history would have them believe is there.
If I'm barking up the right tree get back and I'll point you in the right direction.
This can be a little buggy for Netscape users though and is not ideal.
Their browsers may have cached the old images.
Since there are many different pictures being displayed in the third frame, it would be best if I could put code in that affects the whole page, rather than adding code to each <a href.
That's not how it works with frames.
You can tell a hyperlink to open a target frame (and refresh it in the process) or you can target a specific file name (pagename.htm or similar) which will be refreshed on point of load.
You are talking about something a bit more global though.
Which web authoring software application are you using ?
The reason I ask is in most good authoring programs, if you change the name of a file the links leading to it from other pages will be automatically updated.
Let's say your visitors have a cache of mainpage1.htm and its image. If you rename it to mainpage2, it is a new document with no relation to the old one as far as a browser is concerned and so should be loaded as a new file along with the replacement image you put on it when you renamed it.
Dreamweaver, FrontPage and similar all have that feature where if you right click and select Rename, you get a prompt whether or not to update the links to that file.
It could be a quick and easy answer but depends on your software.
Frames are always a headache for this (and other) tasks which is one of many reasons why I avoid them like the plague.
Get back to me with your software type and we'll go from there.
I used "Notepad", saved the page as extension txt and renamed to html. Isn't that what all programmers do?
the website is click here
Every week I upload new results as a jpeg, overwriting a default picture. Up until now I have had trouble confirming the new picture (results sheet) has been uploaded successfully. Now I can CTRL F5, to check it myself (thanks), but visitors may wait indefinately for the results.
"Isn't that what all programmers do"
No, it isn't, and since you did not supply the information I had to ask to try and offer a suitable fix.
If you used a web authoring program (most designers do to speed up development) you could have used the methods outlined above to rejig your files quickly easily and effectively.
I'll have a think or perhaps someone else has a simple solution off the peg that may be used. Without amending filenames, target of hyperlinks or similar I can't think of anything offhand that would work the way you want it to.
I thought I had supplied the information. I have not used a specific program. If necessary I will put this Onclick line in all hrefs (onClick="frame.name.window.location.reload(true);". ) Presumably part of this line I have to replace with my specific info?
