Javascript - How To Pass A Value From The Serverside Page To A Function In .JS File
Jul 30, 2010
I have to pass a string value from the server side page (.aspx.cs) to a function in .JS page. I need to call the function in JS page from server side page along with string as a parameter.
the question says it all : i have a linkbutton to which i pass through CommandArgument a value and i need that value to be a javascript value.Edit : here is my linkbutton tag :
The first commented line below is working with a hardcoded ApplicantId, and all I need is to make it work by passing the current ApplicantId column on the same gridrow.
I've tried for many days now, and something like the second commented line does not work for me.
pass name of the textbox Control to javascript function
[Code]....
<script type="text/javascript" language="javascript"> var sum = 3; var textboxObj,ObjName; function validate(textboxObj,ObjName) { alert('Hello'); var arrayOfObjects = document.getElementsByName(ObjName); alert(arrayOfObjects.length); for (var i = 0; I < arrayOfObjects.length;i++) { alert('Inside for loop');............................
Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function function RefreshParent(inputDate) { window.opener.location = window.opener.location + "?Date=" + inputDate; } .NET Code-Behind Protected Sub RadGridOnlineRequests_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridOnlineRequests.ItemCommand If e.CommandName = "ViewOnlineRequest" Then ' populates LabelScheduleDate among other controls values ScriptManager.RegisterStartupScript( _ Me, Me.GetType(), "clientScript", "RefreshParent(" & LabelScheduleDate.Text & ");", True) End If End Sub
I have a function that gets the position of a control.
[Code]....
All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:
function (getPosition) { var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>'); getPos(txtBox1); }
I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.
In a repeater control there is TextBox and corresponding to each TextBox there is Button control.On click of Button how can i pass TextBox's text that user has just entered ?
Below is the code:
[Code]....
Means on click of each Button how to pass there respective TextBox's data to a javascript function ?
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:
I am writing an ASP.Net application. I am making use of master page in it. I have several child pages with me, which consist of some java script functions; Let's say;
function ChildPageFunction() { //Do something; }
And master page java script function as;
function MasterPagefunction() { //Need to call ChildPagefunction(); here }
Now is it possible to call ChildPageFunction() from MasterPageFunction()?
<%-- script to load the default image--%> <script type="text/javascript"><!-- window.addEventListener('load', function () { // Get the canvas element.
[Code]....
If you look at the img.src at the very bottom, it loads the defaultImage.ClientId from the server which is suppose to get the image on the page. If I use a normal url it works, but if I use document.getElementById(imgid).src it just doesnt load an image. I am assuming its because the javascript loads before the serverside code is ran. How can I get around this?
FOr this i Used __doPostBack but page flickering is occured eventhought if we keep update panels,
I have a gridview control from gridview I am calling RowCommand event and then a Popup Page from Popup i will return some values and again i need to bind the values back to the DataTable and then to GridView.
In JS if i User doPostBack('xyz','') page flickering is ocurred and if i user doPostBack('updatepanel1','') ID also flickering is not occuring bt values gets binded to GRidview after 5 sec delay....
is ther any alternate sol for this to do...
any Jquery or any JS???
or if i use ScriptManager Page Method is there any issues with that bcz we need to have a static method in server side.....:(
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.
[code]....
I want JavaScript functionClickMenu(this) at input button [id="ButtonMaster1" @ MyMasterPage.aspx] pass its value ["Menu-1"] into text box [id="TextBoxDefault1" @ MyDefault.aspx], and then performing update / doing post-back to server ONLY FOR UpdatePanelDefault1.
I am looking forward an example code for JavaScript functionClickMenu(this).
