Web Forms :: Passing Data To Javascript?

Nov 9, 2010

Is there any way to pass a List<T> that's generated during the page load process to a Javascript function that's called when the user presses a button without having to manually serialize/deserialize the data every time (such as is the case with XML/JSON cookies)?

Forms Data Controls :: Passing Repeater Container.dataitem To JavaScript Function?

Sep 16, 2010

I am collecting user roles into a single dimension string array.

I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'

All is good till this point.

But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):

DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function

Can I do that with a single dimension array?

Javascript - Passing Data Between A Parent Window And A Child Popup Window With JQuery

Dec 3, 2010

I have the following HTML

<tr>
<td class="label" valign="top">
Affiliate Party
</td>
<td class="field">
<input type="hidden" name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyId" id="AffiliatePartyId" />
<input name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyName" type="text" id="AffiliatePartyName" class="PartyLookup" />
</td>
</tr>

and the following Javascript/jQuery

$(".PartyLookup").after("<img src='Images/book_open.png' class='PartyLookupToggle' style='padding-left:4px;' />");
$(".PartyLookupToggle").click(function () {
window.open("PartySearch.aspx", "PartySearch", "width=400,height=50");
return false;
});

I need to be able to flag ANY PartyId input field with class="PartyLookup" so that it will modify the DOM and include the image next to the input field. The popup window returns data to populate both the hidden and text fields, but since the click() is generic I need to pass it the ID of the input field.

Passing Complex Objects To Javascript Via IScriptControl?

Mar 24, 2010

I'm playing around with a asp.net page that's using the IScriptControl interface to pass data from the code-behind to the custom javascript object running on the browser.I'm passing a number of properties via IScriptControl.GetScriptDescriptors(), and they're all working fine, except for one.That one is a class derived from System.Collections.Generic.Dictionary<>. And even that one has been working for me, so long as the elements in the collection were scalars - ints, doubles, and strings. But when I tried to pass a member of a class, it showed up as a null object in the javascript. The class in question is marked [Serializable]. I changed it to a struct, and got the same behavior.It looks as if the serializer used in IScriptControl does a shallow copy.

Passing A JavaScript Variable To A Helper Method?

Feb 24, 2011

I 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>';

Javascript - Passing JSON To Controller Action

Mar 7, 2011

I have the following javascript. Problem is if I enter one row in the table "ingredients" but I am getting 2 rows in the resulting pass to controller action after seralising into my C# object. But the second object is null? I checked the javascript and the variable "cnt" is 1 not 2. Why would that be?

[code]

$("#Save").click(function () {
var title = $("#recipetitle").val();
var category = $("#category").val();
var preptime = $("#prepTime").val();
var preptimeperiod = $("#lstPrepTime").val();
var cooktime = $("#cookTime").val();
var cooktimeperiod = $("#lstCookTime").val();
var rating = $("#rating").val();
var method = $("#method").val();
var jsontext = '{ "RecipeTitle": "' + title + '",';
jsontext += '"CategoryID":' + category + ',';
jsontext += '"PrepTime":' + preptime + ',';
jsontext += '"PrepTimePeriod":"' + preptimeperiod + '",';
jsontext += '"CookTime":' + cooktime + ',';
jsontext += '"CookTimePeriod":"' + cooktimeperiod + '",';
