Is it possible to "properly" delete a single element from an array /object?This seems strange:
javascript Code:
Original
- javascript Code
alert(searchlist.length); // 4
[code]....
Do I have to overwrite the old object with a manually created new object?
I am trying to develop a small web based inventory programme. In the programme, after orders are placed for supply of an item, the materials are to be recieved by the stores. For this a "goods received page" is used. On start the page loads items as per the purchase order in the database. Javascript is used to calculate the cost of each item and total cost of all items. since the number of items vary from order to order I use the following code to load the page. ( PHP is used in the server side).
<input type='text' size='10' name ='rqty[]' value='1.000' align='right' onchange="recalculate()">
<input type='text' size='10' name ='rqty[]' value='2.000' align='right' onchange="recalculate()">
[Code]....
My problem is that the above will work whenever there are two or more items and the variable qty is actually an array. But it does not work when there is only one item. In other words, it does not recognises a single element array. value of rsize is returned as undefined. Splitting the loading process with seperate naming for single items as rqty and multiple items as rqty[] is not possible as option to be given to delete items from a multiple item page. This may end up in a single item page eve n when there are multiple items at load time.

What I am curious about is I am trying to create another array set that is pulling new information from a different source. Is it possible to use the json_encode(); method to encode two separate variables?If not, is there a way I can create the event variable and store both the information you see in the while loop with information that I would store into a new while loop? I'm a little stumped

Im trying to delete an element if the checkbox inside it is checked.
if($j(this).find('input[id^="checkbox"]:checked').length == 1)
{
var parts = $j('input[id^="checkbox"]:checked').attr('id').split('-');
$j('input[id^="checkbox"]:checked').each(function(){
$j('dl#row-'+parts[1]).remove();

});
however it only removes the last element.
In a form, I delete an Input, then submit the form, but the deleted Input still there, don't know why ?
$("#form").remove("#name"); // doesn't work
$("#name").remove(); // doesn't work either
I have a single form on a single page with some js that is supposed to take the first and last name entered and add them to the select list. There seems to be some kind of communication stop between the js and html, because nothing happening.
Here is the code:
<script language="javascript" type="text/javascript">
/* <[CDATA[ */
function Member (){
this.lastName = "";
this.firstName = "";
this.position = "";
this.phone = "";
this.email = ""; .....
I have a choice when creating a new API that I would like other peoples opinions on. Do I use a single Array or Multiple arrays such as: array[1][1] = "ID[56]NAME[Hello World]START[10]"; OR
ID[1][1] = 56;
Name[1][1] = "Hello World";
Start[1][1] = 20;
The API is used for animations so is very heavy work, but would using around 15 multidimensional arrays be too much and a single one be preferable???
I'm new to jquery as you will soon find out. I have a number of divs with the same class applied to them and I want to be able to animate them separately as each one is clicked - right now clicking on one, affects the entire family of like-tagged. I think I might be going about this the wrong way or missing something.

I know that we can split() a string into an array, if we have a string in an input field like this, "javascript rocks"
what if there is only one keyword in the input field?
for instance, it is only a word - "javascript"?
This is my code to add and delete dynamic rows and auto calculate the amount field by multiplying qty and rate.

I have an array of HTML tables created in PHP which I send as a XMLHttpResponse encoded with JSON. Is there was a way I could access the table elements which are now in the JSON Object?

i have this user interface for a client that i have to mod (The UI is a link crawling monitoring for his website), the present one uses php database connection for every single action that is done on the UI (select link to be monitored, show link stats etc...) what we want to do is to have the links retrived from the database stored in a json object while the client is playing with the links on the UI (making all kind of editing actions) and then when he want to store all the modifications/actions he has made then the data stored in the object are sent back to the database...
One of my coworker's (he's a java and O.O. programming specialist) objection to that is that there are too many links (data) to put in a simple Json object... and it will be then difficult to store all the actions made on the json object because there will be too many info/data for it to handle etc...
I have such problem when I post my object from client to server (php).
The object should be like so:
Code:
I converti it:

And send it though jquery and ajax:
property val is the object...
Then on side of server I gota string $_POST["val"]:
