I'll try that but meanwhile i moved the function to global scope and i pass the object to it. It works just fine but
it's not -in- the object so it ruins my OO way of thinking... (i'm mainly C++ programmer and JScript is new to me).
I made it like this:
function timedAnimate(elementId)
{
if(elementId.Stop == true)
{
return;
}
elementId.setPosition(elementId.Position + elementId.IncDec);
if((elementId.IncDec < 0) && (elementId.Position <= elementId.ValTo))
{
clearTimeout(elementId.t);
elementId.Stop = true;
}
else if((elementId.IncDec > 0) && (elementId.Position >= elementId.ValTo))
{
clearTimeout(elementId.t);
elementId.Stop = true;
}
else
{
elementId.t = setTimeout(function() { timedAnimate(elementId) }, elementId.Interval);
}
};

Hi all,
I've kind of design where once an item is selected from a dropdownlist (HTML select) a new dropdown list is displayed with relevant items. It can be upto another level too. For example, say I've a dropdown to select the country. Once I choose the country relevant cities are displayed in another dropdown list below the original one. Once a city is selected from new list, hotels is displayed in that list.
Now say I submit the form and do the process. That part is fine. But once user click back button (to come back to that dorpdown lists page) I want to preserve user selections.
Any idea that how to do it.
All the lists generated with AJAX calls. Since dynamically generated list from the second level I cannot do with JS, using getElementByID() i cannot find them.
Comments really appreciate.
Thanks in advance
I appreciate your help all the time...

Hi
May be this would be helpful.
1. before navigating from Dropdown page to another page you should save all the Three selected values (Country, City and Hotel in hidden field).
2. When you will get back then check is hidden field contain value.
3. Execute process one by one like
first get the Countries using AJAX call and set selected values according to Hidden field value.
and so on for the hotel...
The above is algorithm and i am not sure it is work or not but you may try something like that.
Thanks,

Thanks for the comment.
Actually what I've done was pass URL parameters with pre-define conding mechanism in my application. Your suggestion is worth to try, but I've already done it in that way. I'll give a try later on your suggestion.
Thanks again.
I appreciate your help all the time...

How status bar can be refreshed inside a loop? Is it even possible?
for(i = 0; i < items.length; i++ )
{
if(items[i]._category == category)
{
window.status = ('fillItemContent()' + ": " + i);
.
.
.
}
}
That doesn't work.

status will probably not update as the message pump will not release until the loop stops and functions exit.
This is the same for windows forms etc.
I don't think you can force a refresh as you can with forms apps either.
One option might be to update a shared variable and then set up a timer that update the status based on the shared variable value and then the timer retriggers its next update timer tick. Use a flag to determine if the timer should continue to update or not.

I'm new with JScript, i'm C, C++ coder. Would u be kind enough to show me an little example. So, i make global variable or pass variable to setTimeOut method and update the status bar in there - or...what? The goal i want is to show load progression in status bar...and just practicing for fun...

Id doesn't update the status bar in the loop...
var autoUpdate = true;
var autoUpdateString = "";
function updateStatusBar()
{
window.status = autoUpdateString;
autoUpdateString += ".";
}
function fillItemContent(category)
{
.
.
.
for(i = 0; i < items.length; i++ )
{
if(items[i]._category == category)
{
if(autoUpdate)
{
setTimeout(function() { updateStatusBar(); }, 10);
}
...
}
}
}

That is not how it should be. You need to drop the loop, just have a function that executes one iteration of it, and if it isn't the last iteration, use setTimeout to call itself again. That way the main (and only) thread gets relinquished for a short while, so the GUI can be updated and more calculations will happen later on.
Here[^] is an example.

You are still trying to use a loop.
You should perform an incremental increase on one item in each update then re-initiate the timer to call the update process for the next update, repeat until all items are updated.

here is what you should do:
1. remove the for loop
2. look closely at the example given by Dave
3. stop removing your messages

Hi all,
is there any issue that you comes with chrome and IE when setting script with innerHtml in div element?
I'll explain it in this way.
I've define my own div element as popup message (just by floating on top of the page) and works fine. I can set html text on it as well properly. But when I set some script on it, FF works fine but chrome and IE not works fine. Anyone of you have an idea about that?
Hope you are clear with my issue, if not please let me know.
Thanks
I appreciate your help all the time...

Can you provide an example that doesn't work in IE? Until then, here are some general guidelines:
Use "innerHTML", not "innerHtml".
Use createElement, set its innerHTML, then add it to the DOM, rather than adding the element to the DOM then setting the innerHTML. So, do this:
var newDiv = document.createElement("div");
newDiv.innerHTML = "Hello, <b>World</b>.";
var oldDiv = document.getElementById("myDiv");
oldDiv.parentNode.insertBefore(newDiv, oldDiv);
oldDiv.parentNode.removeChild(oldDiv);
newDiv.id = "myDiv";
Alternatively, avoid the use of innerHTML completely:
var mainDiv = document.getElementById("myDiv");
mainDiv.appendChild(document.createTextNode("Hello, "));
var boldWorld = document.createElement("b");
boldWorld.appendChild(document.createTextNode("World"));
mainDiv.appendChild(boldWorld);
mainDiv.appendChild(document.createTextNode("."));
Here is a hack that may or may not work:
var mainDiv = document.getElementById("myDiv");
mainDiv.innerHTML = "Hello <b>World</b>.";
mainDiv.innerHTML = mainDiv.innerHTML;
Depending on your specific issue, I've also seen hacks that modify the z-index so the browser knows to refresh the content.
