If you have an object list ex:
var olist = {"daniel":4, "Tom":5};
Is there any way to reference the objects fields w/o knowing their
names? Say for example I pass the list to another function and want to
verify the field names are actually Daniel and Tom or I would like to
count the number of fields(also sorry if fields are not the correct
term). I've tried looking on google but perhaps I'm not using the
correct search terms.
I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.

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 have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});
I am looking for a good reference for JSON (javascript object notation) i

I have following Json string (returned from server) :
[{"rurl":"Asia.com","status":1,"recordType":0}, {"rurl":"Africa.com","status":1,"recordType":0}]
Iam using following code to get JSON values but Iam getting "UNDEFINED" value. I want to access "rurl" => "Africa.com"
success: function(data) {
var encoded = jQuery.toJSON(data);
alert(jQuery.evalJSON(encoded).rurl);
}
What i want is to have a div block display initially so when a user goes to the page they see the registration form, but if they already have an account they can just click a link that says log in and the registration form hides and the login form shows. [code]...
View 5 Replies View RelatedThere's an object:
foo = new Object();
and a property called 'bar' with a value of 1 is to be added to it using
JSON. If I try the following it only demonstrates my ignorance:
var str = "{foo:{bar:1}}";
eval(str);
alert(foo.bar) // gives undefined
Could someone please explain what I'm doing wrong here?
Let's say I have the following JSON string returned from a server-side
process:
{ values: [{"name": "value1", "value": "1"},{"name": "value2",
"value": "0"},{"name": "operand", "value": "/"},{"name": "result",
"value": "NaN"},{"name": "error", "value": "Divide by 0"}] }
I then create a JSON object from it using eval() (tell me if this is
not what should be done).
My question is this...how do I determine (without going through every
single record) if there is a name=error in the values array?
Here's what I do now, it can't be optimum:
var object = eval('{ values: [{"name": "value1", "value": "1"},
{"name": "value2", "value": "0"},{"name": "operand", "value": "/"},
{"name": "result", "value": "NaN"},{"name": "error", "value": "Divide
by 0"}] }');
for (var i = 0; i < object.values.length; i++) {
if (object.values[i].name == 'error') {
//do stuff...
}
}
I thought I'd try object.values.name['error'] of course that didn't
work...

$searchResponse['verificationLists'] = $verificationListsResponse;

i have this user interface for a client that i have to mod (The UI is a link crawling monitoring for his website), the present one uses php database connection for every single action that is done on the UI (select link to be monitored, show link stats etc...) what we want to do is to have the links retrived from the database stored in a json object while the client is playing with the links on the UI (making all kind of editing actions) and then when he want to store all the modifications/actions he has made then the data stored in the object are sent back to the database...
One of my coworker's (he's a java and O.O. programming specialist) objection to that is that there are too many links (data) to put in a simple Json object... and it will be then difficult to store all the actions made on the json object because there will be too many info/data for it to handle etc...
