Cleaning Strings Before Passing To JQuery Ajax Data Parameter?
Aug 2, 2010
On using jQuery ajax on ASP.Net, we are required to pass the DATA through a string-ed json on the parameters needed. My only concern with this is with strings that has single & double quotes. I tried doing a replace on these and insert escape characters but unfortunately it just doesn't work.
Unfortunately, when the new webpage opens, the url contains lots of spaces and I'm struggling to remove all of the spaces. The code actually works but looks a bit messy, see below.
I tried using Ajax & Jquery for the following need, but not able to do...
I have Two Forms StringMain.aspx & Returner.aspx.... I have created 4 Divs at StringMain.aspx and a sample text "ToCheck" at First Div.. In the Returner.aspx form page load, i placed a label like this
I have set StringMain.aspx as default running page. So When i run StringMain.Aspx page,
the text i placed in the First Div "To Check" should concat with the label Text "hello" of Returner.aspx and display it together in the First Div of StringMain.aspx like this
I'm building a greasemonkey script to make posting to craigslist a lot easier for our clients.
Basically the flow is this:
User logs into our system (established authentication cookies with asp.net)User navigates to a section on our site called "CraigsList". If they have the greasemonkey script installed it automatically opens up craigslist in a new tab.
The greasemonkey script then does a request back to our site at [URL] to retrieve a list of available items to be posted to craigslist.
This is where it fails because the request to [URL] is not including any of the authentication cookies. I'm not sure if it doesn't include the cookies because the request originates from [URL] and not [URL] or what. I know it's an authentication issue because looking at it in fiddler it returns a 302 and redirects to the login page.
I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
I have a htmlarea (Jquery plugin) where I need to accept longer strings than 2048 which seams to be the limit. I don't have a clue where to look. It's an MVC app and here are the relevant code:
HTML:
<div id="PageTextDialog" title="Ändra texten på sidan" style="display: none"> <% Using Html.BeginForm %> <%: Html.TextAreaFor(Function(model) model.PageText, 30, 30, New With {.style = "width:800px;"})%> <% End Using%> <button id="SavePageText">Spara</button> </div>
JScript:
$(function () { function SaveText(pageID, htmlText) { var retvalue = false; $.ajax({ async: false,
I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file):
[code]...
Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:ProjectsSamplesmytestwebsite'".
I have a simple script making a request to the server:
var DTO = { 'path': path }; var url = 'default.aspx/Get'; var test; $('#getInstance').click(function () { $.ajax({ url: url, type: 'POST', dataType: 'json', data: JSON.stringify(DTO), contentType: 'application/json; charset=utf-8', success: function (msg) { test = msg; }, error: function (jqXHR, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); } }); });
This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:
[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public static MyObject Get(string path) { MyObject foo = new MyObject(); return foo; }
Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]
Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?
For every call I make to this index method a connection is spun up - and is not released again.
So after 20 calls to the page, I have 20 of the connections awaiting command. This eventually ends up with an exception, when I cannot make new connections, because the connection pool is full.
What do I need to avoid this happening? I cannot seem to find a method on the SMO Server object like Dispose, close or similar.
I have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.
Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?
the texts in the spans (say a and b) are concatenated together (to ab), and thats almost what i want But now i want to concatenate them by inserting a hyphen (-) in between (to a - b) I've tried this, but that doesn't work:
What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"] jquery Code so far: $("#saveBtn").click(function (e) { e.preventDefault(); $("#addPanel").slideUp(300); //Perform Save Operation var saveString = ""; $("#addTable tbody>tr").each(function () { var o = $(this).find(".hsaorder").val(); var n = $(this).find(".hsaname").val(); var l = $(this).find(".hsalink").val(); saveString += n + "|" + l + "|" + o ; }); ////// Create Array here or some other method? $.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE}); // Remove all but top table element to return to original state $("#addTable tbody>tr").not("#addTable tbody>tr:first").remove(); });
Basically, I have an HTML Form and would want to pass the data from the form to n asp.net mvc controller, then the controller would return an XML for client side manipulation.
Here is my initial code:
[Code]....
When I run and debug, I get a message that says "attr(..) is null or not an object. I am still trying to learn web development using ASP.NET MVC.
I have 2 classes that are used to mirror the data from an ajax call. One (Customer) contains a property which is name, and the other is an array of Products.
Public Class Customer Private _Name as String Private _Products as Product() Public Property Name() As String
