I have a gridview, in which I am able to get data as per page. But I want to get all pages data.
for(i=0; i<grdview.clientid; i++)
{
var checkboxCell = grid.rows[i].cells[8];
}
For using it. Its only get cuurent page data. How can I get all pages data.
Thanks.
As par your question we are not able to get all page data by javascript. Reason behind that javascript only reads data that present or binded at current time since no postback occur that get data and bind to page.
You only access the current page data.
For this you can get data by javascript and do paging by javacript using jquery ajax.

I have a gridview on my aspx (designer) file. I have added the rows through the generated gridview table through javascript to make the web more performance friendly, and I update the whole table using a save button. But I am not able to get the added rows on my code behind. Is there anyway for the browser to communicate that(new rows) to the code behind?
not an easy way - the server (code behind) doesn't know about any rows inserted by your javascript - so when you post back to the server, the rows are gone.
one solution would be:
Put your data in a server-known input-control, like a HiddenField in a serialized form.
Post back to your server and deserialize the data
Add the desirialized data to your gridview on the server
I have an web page which displays data selected by a category.
The categories are listed in one page (categories.html) and the data is shown in another page (list.html).
Instead of reloading the whole page (list.html) to display the data whenever a new category is selected I want to write a public method which can be called from (categories.html) so that only the data is fetched alone but not the whole list.html page again.
I'm using HTML5 + JS + CSS (JS as in jQuery and Dojo). Is this scenario possible?
I cannot combine both categories.html and list.html as a single file, as I have multiple list.html files for displaying various data for the selected category.
Thanking You in advance...
You can use $.get or .load with jquery to get remote html content
$('#containerDiv').load('list.html')
or
$.get( "list.html", function( data ) {
$('#containerDiv').html( data );
});
from javascript alone I don't think you can do this but you can use any server side language you like for example php.
first you have to bind the click event or any event which is triggered when category is selected and in that event's callback you can use jquery ajax method to call the php script. You have to pass the desired data for example the category name selected to the php script through ajax. Now you can create a html snippet file if you want to simply append data to list.html.
in the js script for list.html you can put an interval that will check for the for the snippet file after say 1/2 seconds and use jquery get or load ajax methods to fetch the snippet code and add it to 'list.html'
I created a table that receives data from a SQL database to a PHP script that parse this back though my AJAX to the HTML page.
With this information I create the table.
It works and the beauty of it: every time the data changes the table changes.
BUT: it reloads the whole table with new data.
What I want is to have it only reload the part that's been updates and then "mark" it until you mouse over it.
Is there any function in JS that allows to compare 2 JSON encoded strings and then only update the part that's not similar?
I have use jQuery but haven't found anything as of yet.I apologies for not showing any code but it's protected from sharing
You have to poll AJAX request to the server after every few seconds or minutes and see if there's any update. If so, you receive that update with say the id or index number of the data which you can replace with the new one. That way you won't have to update the entire thing.
i have a code here but i don't know how to pass it to the other page... basically it is inside a function so before the code there is a function but i think there is no need to worry about that what i need is to change the "alert" so some kind of variable where i can grab the value and output it, and also i would like to ask because the data in that function is an array is it correct if i write it like this? var x=new Array($(this).attr('fill')); and if it is correct how will i grab the array data into the other page?
$('text').each(function(){
alert($(this).attr('fill'));
i have a working link here but in this one i still need to change the alert into a variable i can call
It's not entirely clear what you're asking, but to get data from one page to the next, you have the following options:
You can store the data on your server and each page can get the data from the server or have the server put the data into each page when the page is constructed.
You can write the data to HTML5 local storage in the browser and each page (on the same domain) can retrieve the data from HTML5 local storage.
You can write the data to a cookie in the browser and each page (on the same domain) can retrieve the data from the cookie.
You can pass data to the next page via the query string in the URL.
Javascript variables and properties of DOM objects live only for the duration of the current page. When you go to another page, the entire javascript state is thrown away and does not survive on the next page (it is built again from scratch on the next page). This is why you must store the data somewhere and then each page can retrieve the data.
I have a question about what backend to use. I have a html page that has various dropdown lists. On Submit I want to sent the results of that page to another page to compile the (average) results. Is there a way to do this without setting up a database? I was thinking of sending the data with Ajax and then compiling the data with Javascript on the receiving page.
I've done something like this before so any suggestions would be appreciated.
You can use jquery to check the changes in the dropdown list. Send the results to a jquery ajax page and get the return value as json. The result json can be shown on the same page with jquery.
I assume the page you are talking about is an html or jsp page. Yes you can use javascript ot process the data and then send it to a servlet and get it back to another jsp.
