View 4 RepliesI need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
How I can convert a string to a json array.
start code:
The problem is that .css treats snip[1] as a string but I need it to handle it as a json array.
Bad: .css
Good: .css
I am using ajax to get the followign json string from php
i show the string in javascript code...
now i want to get ID value in javascript.
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)...

{"Super" : [{"Name" : "UOBRSVTG","Location" : "WADTXVBAAL"},{"Name" : "WMWYIOLD","Location" : "DVVRGSEQBS"},{"Name" : "QZLOPGCW","Location" : "TISSQSJQRA"},{"Name" : "ZVGNGPRX","Location" : "LETLPHUJKA"},{"Name" :

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?
I'm a complete newbie to JSON and I'm trying to make some sense out of itI think that what I want to achieve is fairly basic, but I have no clue where to begin. Here's my problem:I want to get the information from this JSON-string, fetch the value for realm_rank and display it within a header-tag in my html-code.
View 9 Replies View RelatedI'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?
I have a string that is like [{"carePacks":

How to convert it to a json structure and how to get data from the data structure, like get "HP 1".
In the following post function, alert(data) returns my formatted JSON string:
{"Locations":[
{"__type":"VEMaps.PinData","Title":"1","Description":"Push Pin 1.","Latitude":49.25295,"Longitude":-124.13042},{"__type":"VEMaps.PinData","Title":"2","Description":"Push Pin

Example:

I want to convert this array to JSON string and to get the JSON string back as an Array.
Tool for converting between JSON and string back and forth? I don't want to use a framework like Prototype just for this so ideally umm, no frameworks please lol
Also on a side note, the eval function doesn't seem to be able to convert all possible JSON strings into an object for some reason. It only works for simple JSON literals.
I have a very simple PHP script that returns JSON like this:
{"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this:
var url = "/test.php";
$.get(url,
function(data){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?
My plan was to insert an HTML string from a JSON file into the DOM. As an example for the format, see [url]. I was wondering how I could get the parse.text['*'] inserted into the DOM.

I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:

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?
I used the code from the following article...[URL]

why does the rolled over image's src return to the original value when the user rolls back off it?
To say I'm new to JavaScript is a bit of an understatement so bear with me. I have a site set up with a variety of layers of toggles. When you enter the site all of the items are collapsed and you click the headings to expand. Each of the toggle-able items have ids. It works great for users who start at the homepage.
However, when I send people to any of the inner topics, all they see is the initial collapsed state of the site. I want to be able to provide a URL that will set the toggle to open, and show all of the content for that section on entry.
Here is my code and js, can anyone point me in the right direction?
