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 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.
View 1 Replies View RelatedCould anyone please explain why my validation doesn't work? When I use only predefined validation methods everything seems to be fine, but when I use a custom method it doesn't do anything until I click submit and then cancels the submit with "$.validator.methods[method] is undefined". The debugger does never jump into the "noBefore" method, I got a breakpoint at the first line. I've tried to write the "notBefore" in quotes in the rules but that doesn't seem to help either.Everything seems to be right, though.

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.

sSql = "SELECT DISTINCT " + "'Action' = '<center><a

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");
}

On the server side I have a php generated session parameter.
I need to pass it to javascript on the client side page.

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.
PHP CODE:
session_start();
require_once("../Modules/Connection_Functions.php");[code].....
I'm attempting to write a piece of code that acts as a client side
validator for all drop down lists on a webform, giving an error if the
SelectedIndex = 0.
Here is what i have:
function clientValidateDDL(source, args)
{
var dropdown = document.getElementById(source*.controltovalidate) ;
if (dropdown.selectedindex == 0)
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
}
However, it does not give an error for any selected index, including
index 0, so i'm presuming the var dropdown = ... line is not correctly
selecting the dropdownlist that launched the function.
ClientValidationFunction="clie*ntValidateDDL" is inserted in the
custom validator tags. and ControlToValidate is also present and correct.
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)
any solution for me?

How to invoke this server side button click event from the jquery dialog ok button
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.
//In WebForm1.aspx, I have:
$.post("WebForm2.aspx", { para1: "value1", para2: "value2" },
function(data) { $("#mydiv").html($("div#div1", data).html()) });
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...
I'm using the AutoComplete Plugin with ASP.NET MVC For some reasonthe client side input value is NULL when it reaches the Server method.
View 2 Replies View RelatedIs 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("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]
PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives
Array(

I am new to jQuery, and learning more about Js by doing. I can hand-code HTML and CSS very well and understand OOP effectively. However, troubleshooting complex Javascript code combined with jQuery is a challenge to me, but I really want to learn. I am using Windows XP Professional and IE 8, FF 3.6.
