Passing Data In Strings

Jul 27, 2007

1) To populate a dropdown control that's on a page with data coming
from the database, the developers concatenate all the values separated
by a pipe character and pass the string to the JS function, which
splits the string and adds the values to the dropdown control.

I think this is not a best practice b/c:

A) If the data returned from the database results in a string that's
too long, it could exceed the limit of the JS string type and some
items would be missing from the dropdown.

B) If by any chance, the data from the database contain pipe
character, it would result in extra elements inserted in the dropdown

Is there a better way to pass data to JS w/o relying in strings? How
can these practices be improved?

AJax :: Data Strings Sent Techniques / How PHP Interprets Them

Jan 24, 2011

I created an HTML table list that uses jQuery sortable and droppable features. When I reorder the list by dragging a row to another location in the list, all works perfectly well. The PHP code called on by the jQuery ajax technique ".load()" works correctly too, and the server side table column gets updated with new "position" values, just like I want.When I drag a row to the little trash bin div I created, the browser side responds correctly but the server side does not. I'm having trouble passing the correct values to the PHP code to trigger the isset($_POST['row']) condition. I've tried with both .load() and .ajax() so far. I'm attempting the long form XMLHttpRequest code now.I've given all the HTML table rows, and therefore the draggable row, an 'id' that makes sense according to a lot of the literature and forums I've read, for example: <tr id="row_16">. I've seen that the 'name' should be setup when constructing the params string to be sent as the data for the POST type request too: <tr name="row_16">.

What I'm trying to accomplish, and where my knowledge is lacking, is in getting this 'id' or 'name' related value of 16 to feed to the PHP code in order to create the SQL command that will delete the row in the database table of the server that corresponds with database table's column id value of 16.If I can fully understand what goes into creating the format for the data sent thru the XMLHttpRequest such as "data:...", params or a serialized string and how PHP interprets them, I should be able to implement POSTs with any of the ajax techniques I've been exposed to so far.Any insight on how these strings are created and packaged for PHP.

Passing Data Between Javascript And PHP

May 1, 2006

I am working on an application in which monthly calendars of events are to be generated. When the page is initially loaded, the current month's calendar is generated using Javascript; the user can also move forward to the next month or backward. For each month, I need to be able to retrieve server-side data (using PHP/MySQL) to fill each day-cell ("td"+i, below) of the calendar with events for that day which reside in the server-side database, keyed by date. Here is a snippet of the code that generates the days of a given month:

var d = 1;
for (i = 0; i < 42; i++) {
var elem;
var elem = eval(document.getElementById("td"+i)); //the day cell
elem.innerHTML = "";
if (i >= startingPos && i < lastpos){
elem.innerHTML = d
d += 1;

In short, I need to get data from the database as the days are created (elem.innerHTML = d, above) or get all the data for the chosen month (probably more efficient), and send it back to the Javascript where it can be parsed and loaded to the appropriate cell(s) in the calendar.

Passing Data Into A Form?

Aug 28, 2010

I am using a variation of this script so that on the homepage of my site, a person can enter their phone number and the data from that form is tranfered onto a form on a second page for the rest of their other data as well as autofilling in their phone number data they entered on the first page.

The output for the code is:

areacode = unescape(params["areacode"]);
document.write("areacode = " + areacode + "<br>");

Strings Not Replacing Strings

Sep 25, 2007

I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.

What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....

Passing Data Back And Forth With A ASP.NET IFrame

Jul 23, 2005

I'm trying to communicate between a parent document that is controlled
through pure Javascript with an embedded IFrame containing an ASP.NET
form. I can quite easily pass data into hidden fields in the IFrame and
submit the form to pass data to the ASP.NET application.

Now the tricky part! (at least for me, probably not for everyone
else!), how can I set a field in the ASP.NET page (using ASP.NET during
a postback), which I can get the value of within the parent Javascript
controlled page?

JQuery :: Passing Information Using Data()?

Sep 30, 2011

I am using jqueryUI dialog, and want to pass some data to it. data() seems the best method, right? The following works. $(".delete").click(function(){$("#dialog-delete").data('row','Hello').dialog("open");}); Now instead of just passing a single value, I want to pass an element. I tried the following, but am obviously doing something wrong. $(".delete").click(function(){$("#dialog- elete").data('row',$(this).parent()).dialog("open");});

Passing Data Between Two Windows On Different Servers

Jun 9, 2006

I'm trying to install a file manager script (part of InnovaStudio's WYSIWYG editor). The file manager opens in a popup window, allows you to select a file from a directory, and then when you click an OK button, closes the window and passes the filename to a field in the parent window.

This works fine. The problem is that I need to host the two windows on different servers (the parent window is on the content management server; the file manager on the client's own server where the files are uploaded).

I can launch the file manager OK, and upload a file and select it, but when I click 'OK' I get either (a) nothing in Firefox or (b) in IE, the window closes but instead of passing the filename to the relevant field, it displays "undefined". Code:

Passing Data From Prompt To Function Assistance?

Feb 7, 2009

I'm trying to pass data I gathered from a prompt into a later function.

1. Should prompts for information be in their own JS file separate from the HTML page? Or is it better form to have the prompts (for info) in the HTML page itself?

2. I have tried placing the prompts to gather info in several places, each time my script seems to stop after the data is gathered and does not perform the calculations which are contained within a function. The input data is gathered from a prompt, do I still need to "return valuea" and "return valueb" in order to use the input data in the calculation function? Initially I did not feel I did, as I am not performing a calculation initially, just receiving input.

I'm making a page for my daughter's school - or trying to. they are having a silent auction and i'm trying to make a very simple bidding page. where i'm running into problems is passing the bid to a text box (read only) where it can be updated when a new bid is entered.

I would like this to be in the upper part of the page with the listings of the auction items, i just can't wrap my head around how to do this. I've gotten as far as the form for entering the bod and contact info. I have the php code to submit. i still have to get the validation js to make it more secure.

Passing Extra Data Along With Form Submission

Jul 15, 2011

Mootools 1.3 user here. I am just wondering if I can pass extra data along with form values when I use the $('myform').submit(); method.

I am wondering if there's anyway to attach data the same way you do with a Request object (ie: Request.send(data) or do I have to create hidden inputs in my form to pass the values?

The reason is some parts of my form are dynamic. The user can add as many entries as he wants. Those entries are stored in an object that's a module's property ( = {obj, obj, obj}).

I am wondering if I'll have to iterate through the entries and create hidden inputs for each before submitting the form or can I just create a string that I can pass with my Form.submit() statement?
