View 4 RepliesI need to send som parameters to the callback function of my AJAX call, how can i do that: ex.
[Code]....
I'm using AJAX Page Methods, but I can't seem to be able to pass the needed parameters:
function getFavStatus() {
//favs is a list of DOM <imgs> that I want to modify their img.src attribute
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt,setFavImg(favs[i]));
}
}
function setFavImg(fav, response) {
fav.src = response;
}
The problem that I can't figure out is how to use the "response" from PageMethods, AND pass the DOM object to the callback function.
I've also tried doing something like this:
function getFavStatus() {
for (i = 0; i < favs.length; i++) {
PageMethods.isFavorite(favs[i].alt, function (response) {
favs[i].src = response;});
);
}
}
In this case, the response works properly, but i is always > favs.length, because it has already iterated through the loop... Edit: My PageMethods.isFavorite signature is: [System.Web.Services.WebMethod] public static string isFavorite ( string p_id )
What is wrong with this code? I am trying to pass parameters to a WCF function. I couldn't get this to work. I am getting Ajax error.
$.ajax({
url: applicationPath + "/Test.svc/GetData",
type: "POST",
dataType: "json",
data: '{GId":' + sender.get_value() + '"GName":' + sender.get_text() + '"mId":' + testId + '}',
contentType: "application/json; charset=utf-8",
success: function(result)
{
//trying to fill combobox here
},
});
<input type="text" id="txtFirstName" runat="server" class="textReg"
onblur="javascript:validate_input(<%=txtFirstName%>,'imgFirstNameS','imgFirstNameE');" />`
I want to send control id to my javascript function
like ctl00_ContentPlaceHolder1_txtFirstName
or
function validate_input(control, success, error) {
control = document.getElementById('<%='+control+'.ClientID %>');
}
is it possible ?

I have a javascript function named as sss() . I want to call it from the code behind.
function sss() {
$("#div-TableContent").show("slow");
alert("its Works");
};
I used this code
Private Sub dataGridView_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles dataGridView.RowEditing
If (Not ClientScript.IsStartupScriptRegistered("sss")) Then
Page.ClientScript.RegisterStartupScript(Me.GetType(), "alert", "sss();", True)
End If
End Sub
but it is not firing when the grid is in the ajax update panel. Why?
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

I am trying to call a javascript function from code-behind using the imagemap onclick event handler:
[Code]....
I'm not getting any errors, but the above is not calling the function. How do I call the javascript function?
how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.
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

How do I call this function from my codebehind? I need to register it through the client script manager right? Can someone provide me the call as I'm not sure how to add the function through an external file using type="text/javascript"
