View 3 RepliesI've got a database written in MySQL with a bunch of PHP interfacing with it. What I want to do is populate drop down menus on a form from this database.
The way I went around solving my problem is as follows.
Code:
Which calls the function from the search.js file, which performs the following operation:
Code:
With element2 being the appropriate preemtied dropdown box, and addOption defined as follows:
Code:
So far so good. This works and produces the correct list of elements in the first dropdown box if the first dropdown box is the target. Here is where things begin to go wrong: On this form I have an add more elements button which is defined as follows:
Code:
And addElement being defined as such:
Code:
While this does successfully create all the cells I want it to create, when I attempt to select Country from the resulting dropdown, I get an empty drop down wit only the "Search For" present in it.
Firebug then proceeds to flag array in selectorfunc above:
Code:
What i believe is going on is that for SOME reason the newly created drop downs aren't being passed js_countries correctly. Unfortunately I don't know how to fix it.
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?
Wonder if anyone can help. I have a page on my website where users can select their country and state/province from a drop down menu. The country and state/province drop down menus get populated from the mysql database using javascript: ie: the user select his country, and the states/provinces of that selected country is then populated into the drop down menu. The code looks like this:<select name="countryList" id="countryList" onChange="return CountryListOnChange()">So the js part onChange will only populate the states drop down menu when a new country is selected.Now the problem is: when the use goes back to his profile, he can see the country he selected, but not any state, since the states list is only populated onChange.

What is the best way to create and populate tables, which will exist in
floating DIVs (with drag and drop capability)? It only has to work
with IE6.
I know of two ways:
1. Dynamically making the tables using "createElement('<table>')",
"insertRow()", etc.
2. Using innerHTML in the holding DIV, to generate table code inside.
3. Is there another way?
What are the pros and cons of #1 and #2? In terms of speed (some of
these tables are huge)? #2 seems easier to wrap my head around, but
maybe less efficient?
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!

View 1 Replies View RelatedI am populating a select box from ajax .. it is loading fine ..But when i submit the form then the value of select box is never passed .. As if there is no select filed on the form ..
Code:
<SCRIPT>
function content() {
var retval="abc";[code].....
So when I submit the form .. The county field is never passed on to next page .
If member clicked 'remember me' on confirm alert after entering the loginid and password, browser will save this information. But if some other clicks on register/join on the same browser, the login and password fields are populating by default. If member didn't say 'remember me', like saying 'not now' or 'never for this site', it is not populating. Note: Both the form names have the same name. Is there anyway to fix it without changing the form name.
View 2 Replies View RelatedI have 2 drop down list that are populated through mysql. They both contain data upon initial page load. However when you select an option from drop down #1 it populates drop down 2 with data associated to it. Sometimes the 2nd drop down list has selected data already and I need it to be cleared back to the first option when the first drop down is selected.
the following code is what I use to populate the second drop down
$.ajax
({
type: "POST",
data: "company=" + $(this).val(),

I'm just now trying to get my head around AJAX in general and jQuery's AJAX specifically.I have a table that is generated from php/mysql. A sample of the rendered page can be seen here. I've also attached a text document with the php code that generates the page.What I'm trying to do is, when a user clicks on one of the edit buttons, I want to open a jQuery UI Dialog popup and populate a form with the current information for the class the user clicked on. Then, after the user clicks on a Submit button (and some basic validation), jQuery's ajax() sends the data for processing to a php script. Upon successfully processing the changes to the class I want to close the Dialog popup and show the changes in the table on the main page.[code]
View 4 Replies View RelatedI have a dropdown (picklist) on the page, and when the user selects one of the company names in the list the onChange event fires and kicks in some AJAX to get the company's details from the database. The details are just the various locations of each company.
The way I am doing it now I have a simple div on the page below the picklist and I am using PHP to draw out the entire HTML, including the values sought from the database, and then just using innerHTML on the div to dump the info in there.
So I have PHP which concats text like:
"<input type="text" name="city" value="$city">"
"<input type="text" name="state" value="$state">"
and then the JS innerHTML's it into the div.
But it strikes me this is not really an efficient way to do this. Should I just have the PHP form an XML doc and then use that to populate the form fields?
If so how do I use the DOM to create text fields on the page, and then populate them with the info returned from the DB?

View 1 Replies View RelatedI'd like to be able to select which drop targets are "live" according to the object being dragged. I tried changing the connectWith in the drag start bit it didn't work. It doesn't much matter how the live/not live is achieved -- making it 'not a drop target', greying it out, etc. I'd prefer not to have to hide the non-live targets, although that does work of course.

this working: I am creating a drop down box using the script below. The
result is two text fields; now I want to pass those values, which come

simply look like this:
