I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?

I am using the ajax control toolkit tabcontainer with 5 tab panels inside of it. Each tab contains areas where one must input information. The page also contains add, edit, and delete buttons with gridviews above them. What I am trying to do is to make the user save or cancel changes when they change the activetab. I am using a javascript confirm box but I need to try to retrieve the value of what is pressed from the javascript box to decide whether to discard the changes or stay on the page and make the user finish the input. Is there any way to save the value from the javascript box into a variable so or must i try something else?
PS I wasnt sure whether to post this in the javascript section or the asp.net section since im using asp.net with c#.This is kinda what im using but would like to turn it into a confirm box and pull the true or false value.

View 2 RepliesI am using ASP.NET MVC 3 and the YUI library.I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such:
window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))';
Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like:
var formatActionLinks = function (oCell, oRecord, oColumn, oData) {
var newsId = oRecord.getData('NewsId');
oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>';
};
I have a hyperlink column in a datagrid that uses DataNavigateUrlFormatString to open a popup window via javascript. I am trying to get two variables from a sql to show in the query string for the popup window. I am able to pass the sessionstart date which is ={0} but the other those two variables in the javascript I am not sure how to pass. The two are school_id and program_id in the select statement below:
strsql = "select count(z.iIndividualid) as enrolled,session_id,school_id as SchoolId,program_id as ProgramId,convert(nvarchar(10),session_start_date,101) as SessionStartDate, session_class_size as SessionClassSize from dbo.cnSchoolProgramSessions cn with
(nolock) left join customerproductdetail cpd on cn.session_start_date = cpd.dtdate1 left join customerproduct cp on cpd.iproductid=cp.iproductid and cp.iSiteId = cpd.iSiteId and cpd.tiRecordStatus = cp.tiRecordStatus left join individual z on z.iIndividualId
= cp.iOwnerId And z.tiRecordStatus = cp.tiRecordStatus where record_status = 1 and school_id = '" & iSchool & "' and program_id = '" & iProgram & "' group by session_id, school_id, program_id,session_start_date,session_class_size"
[Code]....
What do I need to pass in the hyperlink column to get the proper? Hopefully this makes sense to someone
How can I call a .net method in inline code using a javascript variable?My code looks like this:
for ( var i = 0; i < numberIterations; i++ )
{
var result = <%# GetFilterTagURL( myArray[i].Value, false) %>;
//do stuff with result
}
This block is inside a javascript block; the GetFilterTagURL method is a a .net method and I want to pass the variable myArray[i].Value as the first parameter.
UPDATE:I guess that, as you say, I'll have to create a web service to achieve what I want.
I have a javascript variable in the script tag. I am assigning a value to that variable and I want the same value to be assigned to the label control e.g. consider the sample code below :
<body><script type="text/javascript">
var a=window.opener.parent.document.getElementById('description').DataValue;
</script>
<
asp:Label
ID="lblSubject"
runat="server"
Width="142px"
Font-Bold="True"
Font-Size="10pt"
Font-Names="Arial"
>SUBJECT</asp:Label>
</body>
How do I assign the value of variable a to the label?
How can I pass two variable values to a web service web method using JavaScript and a DynamicPopulateExtender?
Some background of my issue:
I have a fully working cascading drop down list accessing a database.
My parent Cascading Drop Down List is a list of countries and the child displays the relative regions i.e.: USA returns Iowa, Maryland, Oregon etc.
I also have a 3rd Drop Down List control that allows the user to select the language to display the region details i.e.: Selecting the language of Chinese will return a list of regions of the USA in Chinese (held in the database).
I now want to display the translated country name from the 3rd Drop Down List in a label on the page.
I cannot just use the text from the country drop down list as this text value remains in English. The translated value must be returned from the database.
So far, I have installed a DynamicPopulateExtender:
[Code]....
I then wrote a web method (in the Cascading Drop Down local Web Service) to return the translated country name. To do this I have had to hard code the countryID (10663) and the translationLanguageID (1331) asshown below:
[Code]....
This does return the translated country name, but the variables are hard coded!
My question is how do I pass the countryID and the translationLanguageID to the Web Method GetTranslatedCountryName() from the DynamicPopulateExtender? Or even if there is a better way to achieve my task?
