JQuery :: Initializing Data Method Variables On Server Side?
Feb 8, 2010
You can use JQuery's data method (e.g. $('#MyID').data('MyVar', 'MyValue');) to easily store/retrieve information.
However, I was wondering if it is possible for my PHP generated page to add HTML tags that initialize the JQuery's data method variables. Regularly, I want server side variables to be accessible client side. It would be very helpful if I could initialize data method variables during PHP page generation.
If this is not possible, are there any suggestions on how to efficiently communicate server side variables to client side?
I want to send three text box values to server using jquery ajax. problem is that, i dont know the exact syntax to send three data. When i try sending one data(also change no.of parameters to one at server side method), its going good but when i try to send three text box values, its giving jquery error:"Internal server error". I think I am not sending data in correct way. Example below contains only two sending data, because i was trying to send 2 data first.
Below is the code:
function testCAll() { $.ajax({ type: "POST", url: "dbTest1.aspx/SendMessage",
I know at this point is that these is a difference in the array formatting between PHP and JS. The magic bullet is supposed to be json. However, this code does not work as advertised.
[Code]...
The variable $prt is list of associative arrays, so to get a value in a particular row manually , $prt[0]['location'] should give me the value for location in the first row of output. All of this works just fine if i hard code this in html and php. However, I want to dynamically produce the rows as needed which requires that a loop employed. The application also requires that the user may add a row which also need to be accounted for when posting.
I think the best solution is to make this a totally javascript entity. All I need to do is to be able to pass in the server side data. Calling JS from PHP does not work, although i have found many places where they show basically the same code , claiming that it works. think json needs a bit of tweaking to make this happen, but i'm not sure how to proceed.
I have a few values and variables that I want to post to a server (without using a SUBMIT button). Is there a way to post data from within javascript - do sockets or connections have to be open for this to work?
I know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client.For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead.
What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once?Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it.I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying.
I run a carousel plugin which has initializing variables on my index page, which looks like:
Now what i need is an onclick event which tells the script to update the variable 'start' to '500' and then re-run the script without a complete page reloading....
I am building a client-side and server-side solution and want to use JSON through Ajax in both directions. I have ASP or JavaScript server-side, though Microsoft's support of server side JavaScript seems nil, so I am reluctantly conceeding to use ASP. I'd appreciate suggestions on available solutions to encode/decode JSON on the server-side (ASP or JavaScript). I don't plan to load jQuery server-side so that rules out plug-ins. I'd also like to know what is the latest client-side encode/decode for JSON. Is it built in jQuery or a plug-in? In both server and client, decoding JSON securely is key, so using eval () to decode is out.
This is probably a really simple question. Is it possible to initialize x amount of variables. Like someone enters 10 into an input box and it makes 10 variables called variable1, variable2, variable3, etc.How would you name them?variable + num = 0; ?
I've always wonder if there is diference when declaring and initializing a varible inside/outside a loop.
What's a better practice? Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++) { var name = list[i]; }
or outside a loop routine, like this:
var i; var name;
for (i=0; i<list; i++) { name = list[i]; }
or are both the same....
As a programmer, i always try to practice good programming. I always thought that by declaring and initializing the variable inside the loop, i was creating a new memory space every time instead of just 1 time...
I am developing a web form using python cgi which has two list boxes. On selecting a value from the listbox1, the list box 2 should get auto populated with appropriate values (which are taken from the DB). I have written a javascript function to get the selected value from the list box1. But I am struck with passing the values from the javascript to the python function written in server side in which I have written the DB related stuffs.
I want to invoke a Client side javascript function and pass the value of the ID. How can I accomplish this such when a user clicks "Open" he goes to a new window with the same ID.
I tried this but it does not work: On Server side: sSql = "SELECT DISTINCT " + "'Action' = '<center><a href= 'javascript: NewWindow('+cast(ChangeRequest.ChangeRequest_ID as nvarchar)+ CHAR(34)+)'>Open</a></center>',"
On Client side: function NewWindow(myID) { window.open("ChangeRequest.aspx?ID="+myID,"WindowName","width=500,height=600"); } </script>
I have the following PHP code, which uses server-side validation, which works fine. It the user leaves the text field empty it stores an error in a session array which is outputted on the page where the $_GET['id'] variable came from. I also implemented a snippet of javascript code that just checks to see if the cell is empty and throws up alert box. The problem is that both the javascript code and php error validation are both running when I click submit. The PHP code should be a backup to the javascript code in case the user has javascript turned off. The client-side validation should be the default. Not sure if this change should be made in my PHP Code or Javascript Code.
I have a web form that has a checkbox on it and a textbox associated with it. I want the textbox to be displayed when the checkbox is checked and I want this to happen on the client-side instead of posting back to the server. The checkbox is a server control (asp:checkbox...). I can write some codebehind that will display an alert message upon checking the box that looks something like this...
Page_Load...
Dim s As String Dim scriptString As New System.Text.StringBuilder
chkExpDate.Attributes.Add("onclick", "alertmsg()") scriptString.Append("<script language=JavaScript> function alertmsg() {") scriptString.Append("alert('hi'); }<") scriptstring.Append("/" + "script>" s = scriptstring.ToString()
Page.RegisterStartupScript("startup", s)
End Sub
I used this as a test to make sure the server control was running the script. But, when I change the script to assess the value of the server control checkbox such as checked = true, I get errors and if I just try to display the asp:textbox, it doesn't work either.
I had a import function which allow for user import data from excel file. The number of row was dynamic, mean that user may import hundred or data or may thousand of line.
should i perform client side or server side validate?
the problem i faced was if the import thousand of line, i need display out thousand of text (multiple by 6, cause 1 got 6 fields)
the take a lot of time to loading and cause browser "hang" (response slow)
I have the following client-side Content Management System VBscript which works great, now I'm looking at getting it to work server side so that I can update using online login rather than offline and having to upload files. To be honest, I have no idea where to begin with this,
How can I make the button call the click event so that the server side method btnExecute_Click() can be called? Also, this button calls a javascript function before server side even.
I try this sample [URL], where data is procesed on server. I prepare tables in DB and data. and nothing isn't displayed in datable? Then I create same server_prcosing php and I checked syntax from php it was OK same as json, but jquery.datable did not process any data on screen. source:
From WebForm1.aspx, I have successfully retrieved a string that is dynamically generated in WebForm2.aspx and spit out to a Literal control in a div. This is what I did.
That's pretty simple and easy to understand for you jQuery gurus out there.
Now, I am trying to do the same thing within the single web form. That is, in WebForm1.aspx, I have this jQuery script to post to the same web form (i.e., WebForm1.aspx), but it is not working. Postback works OK, but I am not able to retrieve the dynamically generated string and spit it out to mydiv.
What's the jQuery way to do this? Any example? I searched, but I've only found examples which try to get static string values, which I know how to do.
My login to the site is being processed using ajax, which does a redirect to the members page upon succesfull loggin in.The login feature however can in fact take a while because we need to initialise quite some data when a user logs in (his details, but also his privileges are loaded, his personal menu based on these privileges are being loaded, we are loading shopping cart info, we are initialising personalisation settings, and a whole lot more.It sounds like a big thing, but it isn't, and once logged in, the application is going great. the only thing is that the login proceure can take 3 - 4 seconds, and I would like to be able to show the client the progress of the serverside script:
"Searching your account..." "Validating your privileges" "Initialising your personal menu" blablabla...
To do this, I might just call an ajax call that starts the login procedure, and then issue another ajax call every 1 second or so to update the status based on some session variables I set in the login procedure and that I can serve to the client when th next ajax calls come in, but I would love for this to work a little nicer as in just needing to initialise ONE ajax call which can send back statusupdates from the server...
Is there a way to do this for a while. Say I have a dynamic page that generates some td elements. The syntax here is freemarker but you can easily envision your favorite serverside text generating language instead.
<table id="records"> <thead><th>Name</th></thead> <tbody> [#list records as record] <tr> <td class="trigger" id="trigger_${record.ID}" onclick="showDetails (${record.ID})">${record.name}</td> </tr> [/#list] </tbody> </table> <script type="text/javascript"> function showDetails(recordID) { // normally an ajax post but you get the idea window.location = '/record?recordID=' + recordID } </script>
Now I want to get that onclick out of there and bind it using jquery, but I haven't been able to figure out if there is a way to get the parameter there. Apart from putting it in some attribute and looking at it. Is there a cleaner way?
<script type="text/javascript"> $(document).ready(function() { $('#records td.trigger').click(function() { window.location = '/record?recordID=' + ??? how do i get that }); }); </script>
I know I could look at the elements attributes, something like this.attr("id").substring().etc().etc() .. but sometimes there are many parameters to the javascript fn to generate the post and that approach doesn't seem to viable. and there isn't really a standard attribute to use that makes sense for that anyway.
I am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website
Here is the code. Code JavaScript: var formdata = $("#log-box").serializeArray(); formdata = JSON.stringify(formdata); var notifymsg; alert(formdata); $.ajax({ type: "POST", url: "forgot-pass.php", contentType: 'application/json', data: formdata, success: function(responsedata){ var some = responsedata.split("&"); $.each(some, function(index,value){ //alert("index="+index+"value="+value); }); }, error: function(o, s, e){ alert("Form not posted "+e); }}); formdata alerted gives: [{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]
