How To Change Image Source In Javascript Through The Array
Feb 25, 2011
I have a grid with an template column and in that column I have text and icon, on icon mousehover (on mode) and mousehoverout (off mode) I am changing the icon.
Now when the user click on icon it opens a popup and the icon must be in "On" mode but if the user without closing clicks another row's icon then previous must be in off and current should be in on mode.
I have a simple web page which contains an ImageButton. I wanted to know that is there any way for me to change the ImageSource of this ImageButton while the Mouse is over the element.
I used to change it as follows:
OnMouseOver="src='image/image.gif';"
I want this image to change through a duration.
for example, if you want to change a background image, you use:
I have a web site with a navigation bar on the left side that uses image buttons to select the page you want to see. Each button has 3 possible images - the normal image when the page is not selected, the mouseover image when the the mouse is over the button, and the selected image when the button has been clicked and the page selected. Formerly each web page had its own navigation bar but I have moved the common content into a master page.
The problem I have is how to make the button image of the selected page to be the "selected" image rather than the "normal" image. Basically I need to change the imagebutton source to the "selected" image when a button is clicked and reset it to the normal image when a different button is clicked.
Currently the Javascript looks like this:
var loaded = new Array(); function F_loadRollover(image,imageName) { if (image && image.src && (null == image.out || typeof(image.out) == typeof(void(0)))) { s = image.src;
[Code]....
How can I tweak the Javascript so that the src of the clicked image is "content1_selected" instead of "content1_normal" and then reset it when another button is clicked. This seems like it would be a common need when moving a navigation bar to a master page to eliminate redundant code.
When the thumbnail is clicked it will change the source of ProductImageBig with its hyperlink target. How can i achieve this using UpdatePanel? (Or will i be able to)
I am having trouble accessing an embedded Silverlight 2 media player in an aspx page from Javascript and was hoping someone might offer some insight on what's going on.
What I want to do is fire a javascript event on the client when a button is pressed to change the Silverlight media player media source and then play the newly selected file.
I found what seemed like a pretty straightforward example on the silverlight.net site that looked like this:
[Code]....
However, when I run it, I get an error "undefinedObject doesn't support this property or method".
I've confirmed that the client-side id I am using is correct, and I have tried using document.GetElementByID in place of $find (which is what I use elsewhere on the site successfully; my javascript kung fu is weak and I'm not precisely sure what the difference might be) but it still doesn't work. It all seems like it should work as it was presented in the example, but I only get that error.
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
I am making one user control which is a simple textbox.In this i have one textbox and one image control.I m validating this
txtbox through javascipt.What i want to do is when user enters correct value, image of correct sign should get displayde and vice versa for wrong value.So how can i do this dynamically using javascript?(i.e. How to change image url through javascript).
System.Drawing.Image newImage; using (MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length)) { ms.Write(imageBytes, 0, imageBytes.Length); newImage = System.Drawing.Image.FromStream(ms, true); }
and now I need to have this image as a source for asp:Image (System.Web.UI.WebControls.Image). Is this possible as I know that conversion is impossible?
I have a listing using Array. Originally when coded, it limited the amount that could be listed. I've added to the list, but when I view it on the website, the last three items on the list don't show when I mouse over the list. How can I change the coding to allow for additions?
But simply nothing is getting pushed to the array. I can tell this as I am using the following ASP.NET to write the array to a text file:
<script runat="server"> protected void Page_Load(object sender, EventArgs e) { string path = Server.MapPath(".")+"/"+Request.Form["file_name"] + ".txt"; if (!File.Exists(path)) { using (StreamWriter sw = File.CreateText(path)) { sw.WriteLine(Request.Form["seatsArray"]); sw.WriteLine(""); } } using (StreamReader sr = File.OpenText(path)) { string s = ""; while ((s = sr.ReadLine()) != null) { Response.Write(s); } } } </script>
The name of the text file is correct according to what the user put in the form "file_name". As you can see I made seatsArray a hidden form object so thats what the ASP.NET is trying to call.
Is something in the javascript in the wrong order or something? Because I just can't get it to fill up that text file.
Is there a control that you can use? It can be done by fetching a binaryread from an aspx page but why there isn't a simple free image control that you can put in the page and feed it a byte array?
i have a array in javascript and need to send to server how i can send it in jquery and get them in controller . to send javascript array and get them in controller [c#]
I would to know how to pass variables. I have a variable in javascript but I dont know how to pass it to a textbox. I have read it is so easy using ajax, but I dont know how to use it. I believed this was just for not to have reload. Well, then how do I do it? I read I must use get and post, but I dont know how to use it.. for example I have the code:
function guardar() { var completo = "hola mundo"; }
How do I get the variable completo to pass it in a textbox?
I know that I can declare an array using the following method, but assume there is an easier way.
var elem as new Array();
elem[0] = 1; elem[1] = 2; elem[2] = 3; and so on......
Is there a short cut to simply adding the numbers 0 -20 to an array, and is there a shotcut to adding the 20 nuumbers minus a few such as 3, 9, and 17?
<script type="text/javascript"> var checksSinceLastPostBack = new Array(); function clientSelectedIndexChanged(sender, eventArgs) { var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>"); var serializedCheckData = checksSinceLastPostBack.serializeArray(); if (ajaxManager != null) ajaxManager.ajaxRequest(serializedCheckData); } </script>
The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?
