Maybe (or maybe not). All this means that in the end (when you output the array to the page) you must output the correct Javascript array. It doesn't matter if you clean the data at the data entry or escape/cleanse it when building output.
Hope it helps,
Dmitriy.

Hi,
I have 3 autosuggest textboxs:
text1,text2,text3.
I need that if text1 or text2 was populated then text3 is enabled
and if both of them was erased text3 will be disable again.
I have tried the following code:
Event.observe('locationText', 'onkeydown', onKeyDownPress);
Event.observe('britText', 'onkeydown', onKeyDownPress);
function onKeyDownPress(event) {
var element = event.element();
var textLength = element.value.length;
if (textLength == 0) {
byLocationFlag = 0;
$('KMText').disabled = "disabled";
}
if (textLength > 0) {
byLocationFlag = 1;
$('KMText').disabled = '';
}
}
but when I select by going down on the list (with keyboard arrows) the event is not happenning.
what I did wrong?

I get my suggestion list ok but I don't have the arrows up and down.
If you have an idea why it is happening.

Hi,
if you don't have the arrows - then you should have the scrollbar, I guess.
The mode (scrollbar or arrows) is controlled by use_scroll member variable of autosuggest object.

Dmitriy.

Hi Dmitry
I also have this problem.
With use_scroll = false;
The up/down arrows are nolonger displayed ?
was okay when using prev. version with CSS built in and not external.

I've been e-mailed about this issue recently; this is somehow related to inner sorting.
I'm just back from the vacation - will try to sort out the issues by weekend.

This will be fixed in the next release. The fix is:
1. Find the code:
suggest: function(ot, t)
{
if(ot.length < this.start_check) return;
var al = this.keywords.length;
this.total = 0, this.rebuild = false;
if(!this.field.value.length)
{
this.total = al;
for(var i = 0; i < al; i++)
{
this.keywords[i] = this.keywords_init[i];
this.values[i] = this.values_init[i];
this.bool[i] = true;
}
}
...
Change it to:
suggest: function(ot, t)
{
if(ot.length < this.start_check) return;
var al = this.keywords.length;
this.total = 0, this.rebuild = false;
for(var i = 0; i < al; i++)
{
this.keywords[i] = this.keywords_init[i];
this.values[i] = this.values_init[i];
this.bool[i] = true;
}
if(!this.field.value.length)
{
this.total = al;
}
...

Dmitriy.

1. use_scroll=true, When selecting an element from the list with mouse, it doesn't work: the list closes and the selected value does not appear (FF3).
2. use_scroll=true, When selecting an element from the list with mouse, the first time it does not work (the list closes and the selected value does not appear), second, third and next times it works OK (IE7).
3. use_scroll=true, when clicking in any part of the scroll bar (up/down arrow, grabbable area or empty area), the listbox closes (IE7).
Regards

Not the best "solution", but these issues seem to disappear with use_scroll=false
I would like to use scroll, since it resembles better a real select (combobox).

Hi,
have you been able to reproduce these issues with vanilla script (i.e. the original package)? If not, then the problems are not in the autosuggest script but the onSelect callback.
Regards,
Dmitriy.

I have an input with autosuggest. I added onblur attribute to the input to trigger some function, and it works ok the first time, but after that first call, it does not work anymore (maybe because autosuggest is also capturing the onBlur event?).
This happens only in IE7 and not in FF3.
If I move the function call from onblur to a button+onclick, it works fine.
How can I correctly trigger my onblur function?
Snippet of code:
<select name="codigo_comuna" id="codigo_comuna" class="combos" onblur="seleccionComuna();" > (this method calls autosuggest)
<input type="text" name="calle" id="calle" class="campos" maxlength="100" onblur="seleccionCalle();" /> (this method also calls other autosuggest)
|
|
|
|
|
Solved using html onchange (for values NOT IN the list) + js function call on autosuggest value select (for values IN the list), instead of onblur:
var myautosuggest = new autosuggest('item',myArray,null, function(index,control)
{
//alert('OK');
myAction();
}
);
< input onchange="myAction();" />
Regards
|
|

|

Yes, this happens because for IE script sets the "on[Event]" attribute instead of attaching a handler for the event. This will be addressed in the next release.

Let's say I have "apple" in my array and I type "application" into the form. Then the suggestion list stays there with apple, but naturally I want it to disappear. Have I missed editing some config setting, or is it supposed to work this way?

Hi,
Does this control work on Firefox 3.0.11?
Because for me it is not working on Firefox 3.0.11
With what version of firefox is it compatible?
Thanks and Regards,
Aasheesh

Hi,
control does work with all version of Firefox; just checked in 3.0.11 - works.
Did you test the sample from the original archive or your own adoption?

Hi,
I have a need to edit the display in the textbox, when a value from the autosuggest is selected.
For ex., if the string selected is "6202-PP: Product Piping System", then I want only the string "6202" to be displayed.
Can I do this using the onSelect parameter? If so, can you give a code example of how to do this?
Thanks,
Aasheesh

Hello,
the use of onSelect callback is simple:
new autosuggest("field", customarray, null, function(index, control)
{
alert("You've selected the key: " + control.keywords[index]);
});
function in bold is the onSelect . In your case:
new autosuggest("field", customarray, null, function(index, control)
{
document.getElementById("textbox").value = control.values[index];
});
Hope it helps,
Dmitriy.

Hi,
I am facing one problem here. Please see if you could reproduce it and solve.
When I press down arrow, list is getting populated and I can select with mouse. Now if I enter some alphabet, list of words starting with that alphabet populates, but when I try to select it with mouse, it doesn't.
e.g.:
Here, if I press down arrow and scroll and select 'SRC', it get selected. Now if I type 'S' in textbox, 'SRC' and 'STD' gets populated in the list. Now if I click on any of those with mouse, it doesn't get selected.
Below is the library version I am using in case you want to try it.
autoselect.js :
var autosuggest_url = ""; // Global link to the server-side script, that gives you the suggestion list.
// Used for controls that do not define their own server script urls.
function autosuggest(id, array, url, onSelect)
{
// "Public" variables:
this.time_out = 0; // autocomplete timeout, in milliseconds (0: autocomplete never times out)
this.response_time = 500; // time, in milliseconds, between the last char typed and the actual query
this.entry_limit = 4; // number of entries autocomplete will show at a time (only if not in scroll mode)
this.limit_start = true; // should the auto complete be limited to the beginning of keyword?
this.match_first = true; // if previous is false, should the exact matches be displayed first?
this.restrict_typing = false; // restrict to existing members of array
this.full_refresh = false; // should the script re-send the AJAX request after each typed character?
this.use_iframe = true; // should the control use an IFrame element to fix suggestion list positioning (MS IE only)?
this.use_scroll = false; // should the control use a scroll bar (true) or a up/down arrow-buttons (false)?
this.use_mouse = true; // enable mouse support
this.no_default = false; // should the control omit selecting the 1st item in a suggestion list?
this.start_check = 0; // show widget only after this number of characters is typed in (effective if >1)
this.text_delimiter = [";", ","]; // delimiter for multiple autocomplete entries. Set it to empty array ( [] ) for single autocomplete.
this.ajax_delimiter = "|"; // character that delimits entries in the string returned by AJAX call
this.item_delimiter = ","; // character that delimits key and value for the suggestion item in the string returned by AJAX call
this.selectedIndex = -1; // index (zero-based) of the entry last selected
// Styles:
this.bg_color = "#FFFFFF"; // background color for the suggestion list
this.ar_color = "#D7D6BC"; // background color for the "arrow" rows (used if use_scroll is false)
this.text_color = "#000000"; // text color for the non-selected suggestions
this.htext_color = "#FFFFFF"; // text color for the selected suggestion
this.hcolor = "#93A070"; // background color for the selected suggestion
this.font = "verdana,arial,helvetica"; // font(s) of suggestion items
