Same Behavior As ActionLink From Javascript Function?
Dec 21, 2010
I would like to update the content of a div using the result from an action method which returns a PartialView. The below code would do just this.
<%= Ajax.ActionLink("Update", "Comments", new { id = 1 }, new AjaxOptions { UpdateTargetId = "divComments" })%>
<div id="divComments" />
public ActionResult Comments(string id)
{
...
return View(photo.Comments);
}
Is it possible to have this update occur from inside a javascript method rather than from a link on the page?

I know that I do not want to actually use an Ajax.ActionLink from within a JavaScript function, but for the life of me I cannot figure out how to replicate the behavior. Here is what I have in my MVC 3 RC2 _Layout.cshtml:
[Code]....
I do NOT want to use:
[Code]....
Unless that can be made to populate at runtime, on demand from a script. manually clicking the ""Load Menu" ActionLink works exactly like I want except it requires the user to click the link; I want to do that for them... in this case from the Body onload event.

I am using the following code to create calendar controls on textboxes that have been dynamically created using cloneNode. The problem is that in IE it seems to add the behavior twice to the textbox causing it not to work. Is there a way that I can remove this behavior before it is added in ie only to prevent it from being added again? This works perfectly in firefox
var rawDateControlID = ctrlPrefix + 'txtStartDate' + tblPatientMedicationsRowCount;
var $tstCalendar = $("#" + rawDateControlID);
$create(AjaxControlToolkit.CalendarBehavior, { "id": $tstCalendar.attr("id") + "cld" }, null, null, $get($tstCalendar.attr("id")));

Is there a way to add a Html.ActionLink through javascript? For instance, I have this Edit function in my controller:
public ViewResult Edit(int companyID)
{
....
}
And I'd like to do something like this in javascript:
var id = $("#hdnID").val();
$("#editLink").html(<%: Html.ActionLink("Edit", "Edit", new { id }) %>);
A bit of a crude example, but it's basically what I'd like to do. Is it at all possible?

I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.

I have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

I've some function javascript to check loaded file with FileUpload Control
<script language="javascript" type="text/javascript">
function CheckFileBeforeUpdate()
{
var filePath = document.getElementById('<%= this.upFile.ClientID %>').value;
var validExtension = 'xml';
var ext = filePath.substring(filePath.lastIndexOf('.') + 1).toLowerCase();
if (ext == validExtension) return true;
alert('The file extension ' + ext.toUpperCase() + ' is not allowed!');
return false;
}
</script>
and it's called with Button: OnClientClick="return CheckFileBeforeUpdate();
<asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In"
onclick="LoginButton_Click" OnClientClick="return CheckFileBeforeUpdate();" />
So there's unusual situation: I choose appropiate file, click Login...and it goes on to next functions despite inadequate extension.
Otherwise if I e.g. click FileUpload, but select no file.
Next time I choose some file (even with bad extension) and then function run (shows alert).
Why there's sth like blockade? What can I do to change CheckFileBeforeUpdate() runs everytime?
EDIT
if I select no file there's show alert("Select file to log in"); of course. And then is lock release

I'm working on an MVC application and I ran into a little snag.
I've got a form with the usual textboxes and dropdowns. I decided to use jquery ajax (GET) to load the dropdowns on load (State Names & Salutations).
No matter what I try, for example:
Code:
<AcceptVerbs(HttpVerbs.Get)> _
Public Function ReturnSalutationDropdown() As ActionResult
Dim dropdown As New DropDownList With {.TabIndex = 1, .DataTextField = "Value", _
.DataValueField = "Key", .ID = "ddl_coSalutation"}
dropdown.DataTextField = "Value"
dropdown.DataValueField = "key"
dropdown.DataSource = AppEnumerations.BindToEnum(GetType(AppEnumerations.Salutation))
dropdown.DataBind()
Dim sb As New StringBuilder
Dim tw As New IO.StringWriter(sb)
Dim hw As New HtmlTextWriter(tw)
dropdown.RenderControl(hw)
Return Content(sb.ToString)
End Function
The ID of the dropdown ends up like: ctl00$MainContent$ddl_coSalutation
It doesn't matter if I use a stringbuilder and a loop to create a <select> with <option>'s, the ID always ends up like above.
Do I have to create a javascript function to create it instead?

I am new to programming and trying to write a javascript function to set a cookie value when a popup button is clicked.
In home.aspx
<input id="btnCanOK2" type="button" value="Close" class="popupButton" runat="server" onclick="return btnClose_Click" />
for this button, i have written a javascript function:
function btnClose_Click()
{
document.cookie = 'cookieName=closed; value=dontshowagain';
}
In merchant.login page
In the code behind of the other page, it has to check if the value of the cookie is set to "dontshowagain". If it is set to the value, the function should not show the popup again. My task is not to show the popup in different pages. If it is closed once, it has to stop showing again until the browser is closed.
if (Request.Cookies["closed"] == null)
{
ModalPopupextender2.Show();
}
else if(Request.Cookies["closed"].Tostring() == "dontshowagain")
{
ModalPopupextender2.Hide();
}
Where am i doing wrong?? Now Cookie value is always null :(
