Jquery - Allow User To POST Html String To A HttpHandler?
Feb 11, 2011
I am writing a content management system using JQuery.ajax & C#. The JQuery calls an httpHandler and POSTS the html from an html editor JQuery plugin.
I get an error in the handler about unsafe content (html basically) but I dont want turn off validation for the whole page, just the handler (the handler is part of a web control not the page).
So, is it possible to turn the validation off just for one handler? Or do I need to encode the html on the client?
In the end I went for the encoding on the client at Javascript/JQuery HTML Encoding
I am formatting html in my admin page and wants to send this html as part of Response object. I am redirecting to HttpHandler (Preview.ashx) using Response.Redirect, but how am I supposed to send that html within response and read it from httphandler using HttpContext object in my Handler?
After hours of searching in google, the best examples I could find it creating handlers and writing to its response object. I created an httphandler and invokes using jQuery on my html page. I write the result to variable "deliveryText"and send it viaresponse object but when on my html page when I click submit, it executes jQuery code and my httphandler returns html which is written to the page. What I want is to get that reponse in function(data) and assign it to a div name divData rather then displaying raw html on page.
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
I have created the validation using jquery in my asp.netform with post mehtod.but i have replicate the same in usercontrol.But in useroncontrol i dont have any form and i cant give any action and any post mehtod. how to do validation using jquery in usercontrol.
I am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.

I have to break a HTML content string in to multiple lines. And each line should have some fixed characters, 50 or 60 Also I don't want to break the word..or html tags...

We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.
i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.
I don't want to show Create word in query string . What i have to do. And how to implement the Post/Redirect/Get pattern .Please send me code for this if possible.
I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.
I created my form with <% Html.BeginForm(): %>
and the Controller "Edit" method should be called.
I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:
string val = Request.Form["myDropDownList"].ToString(); and also: string val = Request.Form["myDropDownList"];
Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?
I am trying to go to a view with a speicifed batchId parameter wrapped in a ViewModel, pick a file to upload, get the uploaded file back and store the file data w/ the associated BatchId value in a database.When the form is submitted I don't know how to get back the viewmodel and the PostedFileBase so that I can get the BatchId value.I need the batchId value to associate it with the data I am storing in the database.I have the following Action Method in my Controller to allow adding new customers to the specified batch by means of a file upload and import:
public ActionResult AddCustomers(int batchId) { var viewModel = new AddCustomersViewModel() { BatchId = batchId, //other view
After rendering a view on a Post, a call to RenderAction inside the view will call for the Post method. Is there any way to specify I want to call the Get method instead of the Post?
I created a page that receives an html report from post data. This html is split up into pages and displayed in divs (as well as used to create a .pdf file but I don't think that is a security risk if the displaying it isnt a risk).
My concern is that I had to set ValidateRequest="false" in order to be able to do this. If the page somehow received malicious input with a serverside script or something, would the script run / could this be dangerous?
This is how I'm handling the request: I have a div with runat="server." Then, in the page_load event (i'm using vb.net codebehind) i set the div.innerHTML property to a modified version of the html received via post.
I have a some data which is displayed in div body now i want to import that div content in excel format so how can i do this using javascript/jquery or even c#
which returns <div>here</div><script language=javascript>alert('');</script> The content gets loaded property, but no alert. How would I get a javascript routine to work from an ajax call along with posting the HTML code?
Is it safe to send a POST to a web method with a JSON string containing a clear text version of a password for authentication?Who could sniff that password on the way from client to web method? I saw some posts a while ago on "salting" a password - is that something you do in JS on the client side and then "unsalt" on the server?
