JQuery :: Way To Update SelectedIndex Variables?
Mar 18, 2011
[url]
This is my sample code so far. Currently it only works for "Akali" under the "Select a champion..." dropdown list.
The way it works is, you select a level from 1-10 from the "Select a level..." dropdown list, and then you select Akali from the other dropdown list and her "Health" is calculated by "lvl * 80 + 510" which works perfectly. But the problem is if you change the level that value does not update automaticly. Instead the person using it has change the level to the new level they desire, change the champion and change it back again for it to update. Which normally would be ok, but I will be adding much, much more data to the page and I can't ask people to have to update stuff 10 times just to get accurate figures.
I took this from the w3schools jQuery tutorial and built a button, so ignore the way it currently works. I guessed that with a button it would when pressed it would take the latest, aka current selectedIndex values and all would work fine, and it does actually. But I just wanted to ask if there was any way to keep all the information updated at all times without a button, or maybe a button that will update everything on the website with just one click?

Now what i need is an onclick event which tells the script to update the variable 'start' to '500' and then re-run the script without a complete page reloading....

Is it possible to trigger a change event on a select field when the selectedIndex or val is set with jQuery? I've tried it and it doesn't seem to work. I'm attempting to replace a select field with one of my own design. The issue is if i attached a change event to a select field, when the index is changed it needs to fire that event. Basically if a select field is replaced with my list and a seperate script is set on the select list, I need that seperate script to fire without knowing what it is.

I'm trying to get the value associated with a selected index in a drop down list.
Here's an example:
HTML Code:
<select name='elem'>
<option id=颼' value='Hello' name='hello' />
<option id=餠' value='Hello' name='hello' />
</select>
My Javascript is as follows - THIS CODE DISPLAYS CONTINUOUS VALUES: 1,2,3...
Code:
alert(elem.options.selectedIndex);
If I were to use the following, I'd get 'undefined' alerts
Code:
alert(elem.options.selectedIndex.value);
The thing is I need the value, not the index.
Any ideas/references?

I am trying to figure out if there is a way to get the selectedIndex of a select by its value, without going through a loop to check for it.
I know the value of a select, and I want to make the option be selected. But I don't know the selectedIndex. Was hoping to do it without going through a loop to determine the selectedIndex

I have one select, I can say wich element is selected:
<select name="myselect">
<option value="100">A</option>
<option value="101">B</option>
<option value="102">C</option>
</select>
this line will select the option B
myselect.options.selectedIndex = 1;
but, how can I do if I want to select the option B without knowing it´s position?
I mean, I want to select the option B and the value 101, but I don´t know it´s position
any idea?

I have the following snippet I'm trying to make work in Firefox:
Code:
for(var j=0; j<sBox.options.length; j++){
if(sBox.options[j].value == 68)
sBox.selectedIndex = j;
}
No errors are thrown and the correct index is not selected.
However, when I add the following line to the snippet, it magically works fine:
Code:
alert(sBox.options.length);
for(var j=0; j<sBox.options.length; j++){
if(sBox.options[j].value == 68)
sBox.selectedIndex = j;
}
Instead of using alert, I've tried simply assigning sBox.options.length to throwaway variable, but I end up with the same results as the first snippet.

I'm using selectedIndex to change an option in a listbox, but I'm finding that the onChange event doesn't fire unless I manually make a selection. Is there any way to effect the change by JS so that the event works?

JavaScript DOM:
The followin code works fine with IE and Mozilla but does not preselect

for (var i = 0; i < optionArray.length; i++)
{
myNewGrandChildElement =

optionArray[i]["value"]);
if (optionArray[i]["selected"]!=null)
{
//myNewGrandChildElement.setAttribute(''selected'', ''selected'');

If the user types "a" then the select box is populated with "Choose An Animal...", then the three three animals beginning with A. So far so good. But if the user selects say Albatross and then types the letter b then the option "Bear" is selected rather than "Choose An Animal". Although the code is sel.selectedIndex = 0; (not 1). How can I force the selected index to 0 when a choice has been made previously? Is this a bug - if so it is the same in IE and FF.

After I update JQuery autocomplete plugin (jQuery UI Autocomplete @VERSION), I found one issue. The issue is as follows. When I type "jua" in the autocomplete field. Four matches are returned for users with the first name juan. Then add an "n".Only the first match remains in the list. I have come out from this issue by changing the parameter cacheLength:
0 in place of 1.
$field.autocomplete({
url:ac_url,
cacheLength:1,
For the autocompletion data, it reads from the configuration files.Say in the files the data are in this way.
[code]...
It works for previous issue, But creates another problem, If i change cacheLength to 0 then if i add some new name in the configuration file then it is not taking that updataed data. If i change to 1 then after i type "juan" it displays the last one. That is "juanw" and it not displays the other 4name.
