I am having a difficult time with scope. I'm using the following code to populate an array from XML data:
var Point = function(pX, pY)
{
this.x = pX;
this.y = pY;
[Code]...
When I break at the for loop in firebug the points array is empty but if I break in the jquery each loop I see the the point object being added to the points array.
I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.

<div id="imageHolder">

<div style="width:770px;height:400px;overflow-y:auto;margin-bottom:5px;">
<img src="[URL]" alt="" width="750" id="mainImage"/>

<img src="[URL]" alt="" width="240" height="120" onmouseover="Images = this.src;alert(Images)" />

<img src="[URL]" alt="" width="240" height="120" onmouseover="Images = this.src;alert(Images)"/>
</div>
Ignore the onmouseover code I was attempting to do this but so far no luck.
I am not sure this is possible but it seems like it should be. I want to populate a javascript array with all the image files in a dorectory. I want this to be dynamic so that when I add an image to the directory it get included in the array.
Any ideas? I am sure there are many javascript wizards out there who can point me in the right direction.
I have a pre-populated array in a JavaScript. How to populate TEXTAREA field with the text from that array, each entry on different line on page load? Say, value at index 1 will come at line 1; value at index 2 will come at line 2 and so on.
View 3 Replies View RelatedI'm having some issues with my code. I'm trying to pull data from one array and use it to populate a new array. With my initial array I can get the results of certain properties using 'servos[i].application'. Any servos that share their value with that of my filter box should be put into a new array called matches and allow me to referance them in a similar way 'matches[i].application'. At the minute I've got my code to populate the new matches array, i'm pretty sure, but when I try to get data out of the second array using the 'matches[i].application' style of query it says its undefined. I already have an array called servos which is full of 49 different servo objects. I've added the function containing this code and commented it too.
PHP Code:
function dataPull(){
//create servoStore to build page for display
//var servoStore="";
// search and get servos meeting application filter settings
// create new array called matches with set properties
var matches = new Array("application", "sclass", "type", "motor", "bearings", "gears", "modelno", "name", "speed", "v3_3", "v4_8", "v6_0", "v7_2", "weight", "dimensions", "opvoltage", "image", "description"); .....
I want to use arrays to populate an HTML list. I can populate the main list items but I can't seem to get the sub list items to work.

var subPages = ["sub1","sub2"];
for(var i = 0; i < pages.length; i++){
var page = pages[i];

if (page == "page2"){
document.write('<ul>');

Below is the code I use to populate a textboxes (compaddress) when I select the compname from the dropdown. I would like to be able to populate other textboxes such as the compdescription, compmaincontact and others when I select the compname from the dropdown. I think that I need an array but I really would like some advice on how to do it as all of my attempts have failed so far
Code:
<script type="text/javascript">
function showname(what)
{
what.form.textfield.value=what.options[what.selectedIndex].title
}
window.onload=function() {
showname(document.form1.number)
}

I am trying to populate a flot chart using PHP but things do not seem to be working. If I put in the numbers manually for the chart everything is working fine but if I pass them via ajax from a php script nothing displays.
Here is my php:
And here is my javascript:
The background of the chart appears but no data. I suspect that its because the json_encode returns a string.
Here is my Script
$(function() {
$.ajax({
url: "includes/mysql2xml.php",
dataType: "xml",
[Code]....
The xml is valid and I can autocomplete on the names and it fills out the form on the screen with the names of the contact. What I need to do is add the value"" of the input so that it will go into my mysql table when I submit the form.
I have a recipients input textfield called 'recipient', which takes usernames separated by a comma. Next to this field I have a list of usernames wrapped in span tags with a title attribute holding the username. I'm using the following code to set the value of the textfield. However it only takes one username instead of adding to it. I also don't know how to add a comma automatically when a username gets clicked.
Code:
$(document).ready(function() {
$('span.contact').click(function() {
var title = $(this).attr('title');
[code]....
Found this plugin as a solution, which works:[URL]... which I can't get to work:[URL]..
View 1 Replies View RelatedI need to populate a drop down list from sql server via jquery.I'm unfortunately unable to use any server-side type coding
View 1 Replies View RelatedI'm trying to create a function which sends a ajax call and checks a database for entries. If the number sepcified is found in the data, jquery is to populate some input fields with the result.
Example: I looking for 210 and the database found a user with this number, then the ajax returns some information like name, address, postal and city. I created a database call which in a php file created a array with the result: $user[] = array('name' => $row->name,'address' => $row->address,'postal' => $row->postal,'city' => $row->city); Now I can't figure out how to return this array into the jquery function and populate the right html inputs.

As the user types the "start year", I want to fill the "end year" with the same value, keystroke by keystroke. But simply using a keypress eventhandler doesn't do quite what I want, as
$("#start_year").keypress(function(event) {
$("#end_year").val($("#start_year").val());
})
fills in "end_year" with the value before the keypress has been added to "start_year".Again, I just want "end_year" to be the same as "start_year" as it's being typed.
I have a form where a user may select a box from above which will query the database and autofill in the fields. This works properly for all of my input text fields but I have a select box where a user selects their state that I am unable to get to properly populate.
The select box is populated on page load in the following format....
<select id="state" name="state">
<option value="1">ALABAMA</option>
<option value="2">ALASKA</option>
</select>
[Code]....
Everything populates correctly except where I try to set the val on the state select field. It does not change at all. I need it to display the statename with the value of the state (number).
Does anyone happen to know how I would go about populating a text field with x value when a specific image was clicked?
Scenario:
I have a div of 3 images. Each image represents a different color.
When you click an image.. I need a text field to be populated with the color name..
So if you clicked an image that looked like ivory.. textfield would then say ivory.
I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target

I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
I'm looking for a tutorial type of help on using JQuery to create/populate a selection list. I've looked at their site (and searched on their site/google) and although there is tons of stuff there, I can't find what I need.
View 5 Replies View RelatedI have a select field. I must fill with options taken from a mysql table.Here is some little php code I have done using codeigniter framework
$idcateg = trim($this->input->post('idcategory'));
$array1 = array(
'result' => $idcateg
);
echo json_encode($array1);
Now, the jQuery call...
$.post("<?=base_url()?>index.php/rubro/list_ajax/", {
'idcategory' : idc },
function(data){
[code]....
The code works fine. When I call the post, I get the categoryid as a result.Now, I should modify the code above, so I can do:post the ajax call sending the category id. this is done get subcategories for this category, and build the array * json_encode the array and echo * get results back in jQuery ajax call, decode and build the < select > field *The array should be built with each element having a sub-array with id and name, right?
How can I use JQuery to, when clicking a row of data in a table, take that row (consisting of three columns) and populate three different input fields with it?
$('#tableRow').click(function() {
$('#input1').val() = ?;
$('#input2').val() = ?;
[code].....
Here is the code I have written but it is only taking one value out of the several checkbox checked
