Question

Link becomes unclickable while image are loading on page

Asked by: mish_p

I am implementing pre-caching images before next pages loads to display images.

But iif someone does want to precach images and he wants to skip, then there is a link
"skip pre-caching".

I am calling images one by one as soon as page opens. But then this "skip pre-caching" links become unclickable until some images are loaded.Please see the attached screenshot.

why this happens?

Its really urgent. please tell me the solution.

document.write('<a href="#" target="_parent" name="newwin" onClick=self.close();window.setTimeout(window.open("player.cfm?'+path+'","newwin","width=1005,height=900"),0)>');document.write("Skip Pre-caching");
document.write('</a>');

We need to see the other code

Why are you using document.write and why are you closing the page with the script in the middle of executing another script?
That is not a safe way

 

by: mish_pPosted on 2009-10-30 at 03:52:00ID: 25701665

Here I have attached the screenshot and its code.

Actually it is .cfm file with some cold fusion code. but I am sending you code required.

please let me know whatevere is wrong.

Thanks

what is mean by "losing the page with the script in the middle of executing another script?" .

Do you mean I should not keep <a> and </a> in different document.write ??

sorry i misspelled above question.

what is mean by "closing the page with the script in the middle of executing another script?" .

Do you mean I should not keep <a> and </a> in different document.write ??

 

by: mplungjanPosted on 2009-10-30 at 08:33:44ID: 25703974

No I meant
 onClick=self.close();window.set.....

And what is the rationale for all the document.write????

 

by: mish_pPosted on 2009-10-30 at 13:21:11ID: 25706480

why I am writing everything in document.write because I  do not know how to pass java script variable in HTML code.

I am storing parameters from URL to "path" variable and I want to pass this para,aters with player.cfm.

seel the line:

 onClick=self.close();window.setTimeout(window.open("player.cfm?'+path+'","newwin","width=1005,height=900"),0)>');


please let me know if you know the way to pass java script variable in HTML code with out document.write.


secondthing,
how should I write onClick=self.close();window.set...?
can I call one function on onclick and then I can define settimeout and window.close in that function.

mplungjan:

Thanks. That works fine. But still when I click on "skip pre-caching", it opens the "player.cfm" but still downloading is going on. it does not stop.

Is it because we are opening player.cfm on parent window( which has preload.cfm).

please tell me the solution.  As soon as I clicked on skip. it should stop downloading.

Thanks

 

by: mplungjanPosted on 2009-11-03 at 00:41:01ID: 25726990

Really?

It should not be possible
_parent is the window or the parent window of the page with the script.
It should stop immediately

Can you paste the view-source of the page into the code snippet here?

 

by: mish_pPosted on 2009-11-03 at 09:30:25ID: 25731327

thisis the  total code

i am waiting for your reply

1. what is the name of the cfm that is currently executing the preload?
2. is it in an iframe?

If the name of the cfm is player.cfm, then the preload does not CONTINUE but is instead RESUMED

It is not possible that the preloading continues if the page that does the preload is removed from the browser - if you replace a page's parent window, then that page is unloaded and the preload stops.
If you open  a NEW window or tab then of course the preload will continue and you will need to replace the preload page with a blank page or another page


 

by: mish_pPosted on 2009-11-04 at 01:35:04ID: 25737663

yes correct..preloading is RESUMED.

well the flow is something like this..

when i click on button "launch"(which is in launch.cfm), it calls preload.cfm( which pre-caches images) and once pre-caching completes, opens up an new page "player.cfm" ( pre-cached images are displayed on this page - purpose of pre-caching)   [ that works fine]

second scenario is launch.cfm calls preload.cfm .now when we click on"skip preloading", it should stop pre-caching in between and it should open up player.cfm.


player.cfm opens on parent window( where preload.cfm was executing) but it Resumes pre-caching remaining images (also it shows blank until all the images are pre-cached on player.cfm (even if some images are already  downloaded before skip was clicked).


I have one idea --as I wrote settimeout function to close parent window and player.cfm was opned in another window. can I do something like that.(see the very first code submitted here)


second thing do you how to use flag. everything image starts downloading we can check value of flag  andwe can set false when the "skip" is clicked. i have idea but can you please write a function???

 

by: mplungjanPosted on 2009-11-04 at 02:57:10ID: 25738063

I worry when you say parent window. does launch.cfm have an iframe in which preload.cfm is loaded?
If so, then the window you are talking about is the main browser window (_parent) and preloadin cannot continue
Can you please change this

<a href="#" target="_parent" name="newwin" class="aa" onClick="this.href='player.cfm?'+path">Skip Pre-caching</a>

to this


<a href="#" class="aa" onClick="window.location.replace('player.cfm?'+path)">Skip Pre-caching</a>



 

by: mish_pPosted on 2009-11-04 at 09:30:48ID: 25741720

no ther is no ifram in launch.cfm...

The only iframe is use in preload.cfm . I have called page "link.html" in that iframe. thats all..no where iframe is used.

I used iframe to keep link clickable even if images are loading in preload.cfm however it does not work really..
I mean still link remains unclickable while image starts dowloading. can please give me solution.

 

by: mish_pPosted on 2009-11-04 at 09:41:15ID: 25741815


<a href="#" class="aa" onClick="window.location.replace('player.cfm?'+path)">Skip Pre-caching</a>
 still does not stop preloading..it resumes..

 

by: mplungjanPosted on 2009-11-04 at 09:51:33ID: 25741916

Please do me a favour
Take a view-source in the browser of all relevant pages and zip and post them here
I cannot see what happens and am tired of guessing
