Problem Populating SELECT Element Using The DOM (innerHTML)
Nov 19, 2007
I have a function which, using AJAX (No problem here, definitely returns data), returns a list of <OPTION> elements to the client. Using Javascript I am trying to re-populate a <SELECT> element with its children.
This process works perfectly for Firefox but with IE6 the <SELECT> list stays blank!!
Can anyone shed any light on what the problem is/might be using IE6? I have posted some sample code below..
Javascript snippet
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
document.getElementById("cboArea").innerHTML=xmlHttp.responseText;
}
HTML snippet
<label for="cboArea">Area:</label>
<select id="cboArea" name="cboArea" style="WIDTH: 65%">
<option value="0">Choose an area...</option>
...
!! Originally filled from database source !!
...
</select>
As I said previously the return from AJAX call works fine as I have displayed the results using an alert(); method call and also this it works in Firefox.

With IE 8 when a select element is created and populated the select element appears as if it doesn't contain any options until it is clicked. Once clicked the select element then resizes and the data is displayed. I ran across an article mentioning this issue could be resolved by adding an extra line of code that applies a "blank" style to the element but unfortunately the issue still persists. I'm currently using jquery 1.4.2 and the code I use to populate a select element is:

Take the following:
I want fill a select list with the first list on page load, then depending on which option is chosen, fill another select list with the appropriate list. I'd prefer using only javascript!

I have a site that can consist of one or several (up to 20) select boxes that all list the same data (TeamID, Team). There are about 8000 list items to be loaded in the select box.This data is fetched in a seperate file using php+sql and with javascript and ajax, I populate the boxes. Note that these are populated on page load and not based on a specific action/change. The script looks for select boxes that have the class="ajax-team-list". Well, the above works. My drop-downs are being populated. However, it takes an insanely amount of time (30 seconds in IE). Skipping the javascript and only using php to get the same output takes 2-4 seconds, so something must really be messed up in the code, or?Any ideas, suggestions or thoughts about an alternative solution? For whatever reason, Firefox loads the above code in 2-4 seconds, Chrome takes 12 seconds.. and like I mentioned, IE takes 30 seconds.

I am trying to populate inputs on a form from a select drop down list (with date being pulled from a mysql database). This is to allow for any changes that need to be possibly made.
Is this even possible? I've tried doing some internet research, and the books I picked up from the library don't seem to go into this at all, so I'm not even sure that what I want to do is possible. The only thing I can really seem to think is that i need to use onChange. But outside of that, i'm lost.

I originally posted this question in the PHP forum and received advice to try here, they said it might be possible using JS and AJAX.I have limited experience with JS and none at all with AJAX.I have an HTML form in which I have a Select field, currently with about 100 options. The form creates an HTML email using formmail.Dependent on the option taken I get other details, eg address, email, telephone, etc.This is begging to be done via a database and PHP.I do not know if this is possible, but could I open the database, MYSQL, and take all the records into an array, open the HTML form and use one of the fields of the array to create the options list, when an option is selected use the other fields in the array to fill in the address, email, etc fields on the form and then use those values as variables to pass to formmail, which is a PHP program.
I thought that if this was possible I would use PHP to populate the array and then get it to call the HTML form where I could hopefully use the array to help complete some of the fields using SELECT.I would like to know if my thoughts are going in the right direction or if I need to go down another track.

I am having an issue getting my select boxes working in IE. My current situation is that I have 2 select boxes, 1 for Styles and another for Substyles. Not all Styles have a Substyle, but each Style has a different Substyle, so when should happen is when you select a Style AJAX go and gets all of the matching Substyes for that Style.This actually works in Firefox, Google Chrome, Opera and so on, but does not work in IE.Just to clarify, all of my PHP is working 100% and as far as I am aware my HTML is also fine, I have done some checks with the JavaScript and im 80% sure that the problem lies on line 47.

I have a problem with IE7 (Works fine in FireFox!).
I'm sending a Jquery AJAX POST request to get option values from a PHP script.
The php script returns a bunch of the following:
<option value='x'>xxx</option>
Ajax also sends a value to the PHP script, so if that value matches the option value, the option comes back pre-selected.
On success, the Ajax is to populate the SELECT BOX called 'one', with the data returned from the PHP script.
This works fine in FireFox, but in IE7 I get the following error:
Error: Unexpected call to method or property access.
The full ajax function is as follows:
function getbills(){
var transchk = "";
var tranrelation = $("select#catted_relatesto").val();
var tranrelation = escape(tranrelation);

When the page loads there will already be a drop-down on the page, here's an example of the drop down.
<select id="dropdown">
<option value="2121S">Option text</option>
<option value="2122S">Option text</option>
<option value="2123S">Option text</option>
<option value="2121A">Option text</option>
<option value="2122A">Option text</option>
<option value="2121K">Option text</option>
</select>
On page load it will evaluate this drop-down and repopulate it determined on their values. If there is an S in any of the values the drop-down will generate an option for 'S' like so.. <option value="s">S Option Text</option> And for the first code example in this post - the Javascript would be able to repopulate the drop-down with the following:

I just know basic HTML & CSS. However, was working on a project that would require a little javascript. It's for a travel agency and the idea behind it is there is a "booking page" that is basically an html form with a bunch of hidden values (like the destination airport code, the origin airport code, etc). The only thing a potential customer has to do is use a selection list and pick the dates available for that travel sale and hti submit. However, there's a new promotion coming out next week where if you book to travel for certain dates, you can use a promo code to save $100 on your vacation. What I would like to know is if there is anyway I can use javascript so that if a person selects the promotional dates, it auto-populates the promotional code text field.

How would I go about simply populating an HTML select statement from a JavaScript function. You see I have several HTML select statements on one page which are identical (sometimes repeated multiple times) so I wanted to try and cut down on these multiple instances and just have the values hard coded once (in a JavaScript function perhaps) and then called whenever they are needed. Could anyone advice me please, would this be easy to do?
I have the following HTML select statement hard coded:
<select name="bodyFontType">
<option value="">Select Font</option>
<option value="Verdana">Verdana</option>
<option value="Arial">Arial</option>
<option value="Tahoma">Tahoma</option>
<option value="Trebuchet MS">Trebuchet MS</option>
</select>
Would I use an onLoad property on the select statement to call a function which creates an array and then pushes through the values?

I have a multiple select box that is dynamically populated based on a selection from another select box. There are 3 possible results:
1. Every click on the parent select box replaces the html of the child <select> with a "Loading..." message. Then it runs an ajax request to a server side page that returns JSON data back to the post-processing function.
In that post-processing function I check to see if any data was returned for that selection.
2. If data was returned, replace the child multi-select with the data.
3. If no data was returned then replace the child multi-select with a default message.
Now the problem I'm seeing. When I select an item from the parent select that I know returns data, the child multi-select seemingly doesn't update, but when I mouse over the select I see the changes.
BUT! On a whim, I created another <div> just to see if it was in fact a problem with the select, so everytime I updated the <select> I also updated this new <div>. Magically it all worked. So what I ended up doing is keeping the <div> there, just set it to display:none and now it works like it "should".
I'm using jQuery.ajax and jQuery.html to handle the processing.

This is for a test, am not sure what they mean by "do not hard-code the resulting quarter years in the javascript":
instructions: When a user selects a date from the investment cycle drop-down box, the subsequent investment values must display the next three fiscal quarters.
E.g:
Do not hard-code the resulting quarter years in the javascript. (empahsis mine...;-)
The subsequent quarters should be presented with checkboxes which are all unchecked.
Checkboxes in markup:
The values to populate the checkboxes (value and label) have to be hardcoded somewhere, no? what am I missing?

I am populating a ‘Select’ object with data from an Array, and I succeed in load the page with the required data on the ‘Select’ dropdown list. But when I see the source code generated (view-source code) from the browser there is no option on the ‘Select’, you can see this form the browser source code:
...
<body>
<form name="localization">
States: <select name="countries"></select><br><br>
Cities: <select name="cities"></select>
</form>
...
And I want that appears the options generated in order to be able to talk with server, because server is waiting for some value (1, 2, 3 or 4). Now when I submit the form the server don’t recognize the option (value) received. So maybe the source code generated should be: Code:

(and, since markup doesn't change when u set value for chkbx dynamically, how do you check that you have set correct value for the checkbox? (don't know if it shows in Firebug, since don't know if code have there now is correct (have this funky code in there for now.. not sure how to approach this...$('#checkbox1').attr('value', 'Q2 2010');
And how do I populate label? (<label for=""....></label> -- do I need to give label an id? or can you grab "for" attr for a label with jQuery?)

I'm trying to populate select boxes depending on choices in other select boxes. In my case, the person has to choose a type of fixture type, then a select box with all the models would populate, and then a third select box with the watts have to populate.
In my code, the second select box is populating, but the third one is not. I'm sure that the problem is not in the php, but has to be in the jquery side. I'm a newbie in jquery and javascript.

I have a table with a date field in each row:
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?

I'm trying to get a value from a database, assign it to an innerHTML value of a certain element and display this on a web page. Here is how I do this. First I have a js function. Very simple one, here it is:
function get_page_contents(page_name)
{$.post("includes/ajax.php?mode=get_page", {pagename: page_name}, function(data)
{
$('#hed1').html(data.h1);
$('#content').html(data.content);
[Code]...
This javascript function is being invoked upon clicking on a link. The point is that the content's innerHTML is displayed beautiful while I cannot see H1 innerHTML. Its value is NULL instead of expected database value.

I have a situation where I'm trying to assign a value to an elements innerHTML. When I do this, the value is assigned, but it causes havoc on subsequent javascript calls.I realize this is kind of vague but I'm at my wits end on what to do. I've tried assigning the innerHTML value "NA", just plain text, and it has the same effect.Without being too confusing, I have a table of data inside a <div> where the user can navigate up/down by pressing the <enter> key, pg up/pg dn and arrow up/arrow down. When they move from record to record, I'm highlighting the new row and "de-highlighting" the old row. The row has many fields but only one fill in field which is where the user enters the quantity of the item to be ordered. This is on a local network using the Firefox browser.
Without the above line, all is well. When I use the above line, it messes up the highlighting of the row but also makes the fill-in field "appear" disabled. What I mean by that is when you type a number, you don't see the value change (even though the field has focus and the value is selected) but once you leave that line, the value you typed then appears in the fill in. Normally the value will change as you type a new value.

Is there a way I can make this code work:
<script type="text/javascript">
function changeText(){
document.getElementById('boldStuff').innerHTML = 'Fred Flinstone';
}
</script>
<p>Welcome to the site <b id='boldStuff'>dude</b> </p>
<input type='button' onclick='changeText()' value='Change Text'/>
with this:
document.write('<param name=avatarID value=4>');
So when I click the form button it changes the value 4 to Fred Flinstone
