JQuery :: Remove Trailing Comments From JSON String With Ajax?

Jul 12, 2011

I am using a framework, which returns invalid JSON Strings like:

/* { "myobject" : "test"} */

The error is the comments before and after the json string. This has been invented for security reasons. As the www says returning JSON directly is somehow discouraged because it can be exploited. I am not a security expert at all but would like to go conform with this recommendation. However, now I get this string above with header type "application/json" Can I somehow hook into jQuery and tell it to remove /* */ from the json string by default before parsing the json and breaking it into objects?

Keyword - Modify The Src Attribute ?

Feb 12, 2011

I'm trying to get the following function to work:

When called like so:

I could just give each image an ID and not use the 'this' keyword, but I haven't used it much so I'm curious about it. It's sending the image element to the function, so why can't I modify the src attribute with that information?

Modify String - Lowercase Letters And Uppercase Letters In A String And Then Swap Them

Jan 19, 2010

I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.

Meaning all lowercase letter becomes uppercase letter and vice versa.

So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.

Remove Attribute - Loading An <img> Tag With One Thing Or Another

May 24, 2011

Under PHP control, I am loading an <img> tag with one thing or another. I'm trying to work my way towards not changing the actual tag beyond what is already there (don't mess with the HTML).

The HTML is:

Code:

I am switching the image src path to something totally different. A such, I need to have the browser remove the alt and title attributes. I do this by loading the following in the {SRC} placeholder:

Code:

Using FF2.0.0.20, View Generated Output, I see that these attributes are indeed gone. Yet, the browser still shows (definitely) the alt attribute and (probably) the other attributes as well. I have also confirmed this happens with FF4.0.1-Portable.

JQuery :: Treat A String As JSON?

Sep 7, 2009

I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...

Js Variable Not Accepting Json String?

Dec 15, 2009

I am slowly working through learning/writing a JS project.here is the core issue.:

var pt =<? echo json_encode($prt);?>
alert(pt) // for diagnostic purposes

json is flattening the PHP array to be used in the script.However, the alert shows me that I only get {[ ,which is just before the first set of double quotes.JS quits at the double quotes, leaving me with an undefined array.How do I fix this?

JQuery :: How To Pass Object In JSON That Is Not String

Feb 3, 2011

I'm a beginner in Jquery and I have a big doubt, follow at bellow the code to be better viewed: The method below is static and Static methods do not work with instance, For this reason I passed the 'nameLabel' that the typeis Label by parameter, however I need to catch the exception and show it to the user.

[WebMethod]
public static string RetornaNomeCliente(string idCliente,Label nomeLabel){
string nomeCliente = String.Empty;
try {
nomeCliente = Cliente.RetornaNomeCliente(idCliente);
} catch (Exception e) {
nomeLabel.Text = e.Message.ToString();
} return nomeCliente;
}

But I'm using Jquery and this method is used in a Ajax Request and I use the Json to pass the datas, how showed below:
var idCliente= $("#<%= txtIDCliente.ClientID %>").val();
var nomeLabel = $("#<%= lblMensagem.ClientID %>");
var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }";
But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
