I want to programatically re-center the map and add markers elsewhere in my code, but don't know how to access this JSON object to modify it.
The way I'm currently doing this is to call gMap again with some new configuration, but I don't think this is right as I think it's re-creating the map all over again.
I was looking for something that would allow me to scatter elements (divs w/ background-images) behind text. Splatter is almost what I want, but I would need:
- no overlap in the positioning of elements
- keep the elements inside the container
- remove the default asterisk completely
As I have varying article dimensions, this keeps the splatter area the right size:

I am using a json from a Google spreadsheet and a jquery plugin which is called throught this HTML line <ul id="example">.The thing is that when I dynamically append elements to the <ul id="example"> from within the JSON callback function, these are not recognized by the jquery plugin
Code:
<form> <ul id="example">BLA BLA BLA</ul> </form>
[code]....
If I insert an <ul id="example"> plus some <li> in the HTML code the plugin works perfect If I insert dynamically some <li> to the <ul id="example"> throught a javascrypt function before executing the callback (...json-in-script&callback=...) also work perfect.But when I insert dynamically the <li> elements within the callback function (in my case: cm_loadMapJSON) does not work well.
php page is echoing out:{"species":"Please select a species!"} I double checked the response from the php and firebug shows the same. On success alert is not alerting the JSON data instead, I'm receiving [object Object]. Why is that and how do what should I do to fix this?
I'm trying to get points form xml file with for loop, put them inside path that represent my line on gmap. It fails. I tried a lot. XML is GPX file and its not a problem to pull data out with XMLHttpRequest. Then i have for loop:
Server-side code returns a JSON representation of a query like this:
{"recordcount":3,"columnlist":"messageid,messagetext,dateposted,firstname,lastname","data":{"messageid":[3,2,1],"messagetext":["hello? is this thing on???","what? why?","Hello, and welcome!"],"dateposted":["{ts '2010-12-05 11:32:51'}","{ts '2010-12-05 11:32:17'}","{ts '2010-12-05 09:44:30'}"],"firstname":["Mortimer","Tom","Waldo"],"lastname":["Who","Dickenharry","Emerson"]}}
Makes sense, and jQuery converts it to the equivalent javascript object when it comes back in an AJAX response, but I'm having trouble using that with the template plugin. It apparently expects an array of individual objects, each with a field for each query column.The server response is an object containing recordcount, columnlist, and data members, where 'data' is an object keyed by column name, whose values are arrays with the data for each record. It's equivalent, in a familiar format, and a much more concise representation than the javascript for an array of individual objects, since it doesn't repeat the column names for each row, but it's not the same.
In addition to fetching JSON you might want to POST it back to the server, but there is no postJSON method. You cannot use the generic ajax method, either. What is missing is the complement of "eval" to turn a JavaScript object in to JSON. The JSON.stringify function from www.json.org (see json2.js in JavaScript section) does the trick, but it would be nice if jQuery incorporated that out of the box, to save some hunting time.
Using the jquery ajax method to set the "type" to "json" and the "content-type" to "application/json" send and recieve JSON, but you must use JSON.stringify to convert your outgoing object to JSON. P.S.. a lot of forgiving parsers have resulted in a lot of articles on JSON being wrong. would I like to mention that here. Property names are JSON strings. JSON strings have double quotes. Therefore, property names have to be surrounded with double quotes. Single quotes are not JSON strings and not legal (JSON is not JavaScript).
Supposed that I have a json object but I don't know anything about its keys and values. Is there anyway to print out all the key and value pairs in that object?
Do any of you know if you can convert a JSON object into a Jquery object ? The reason i wish to do that is to be able to use the jquery selector to filter my Json data. (for example filter them based on their properties)
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.
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?
jsonObj={ key1: 'value for key1', nextKey: 'nextKey value', lastKey: 'value for the last Key' };
without knowing the structure of this object... is there a way to return the name of the keys?if it was a nested aray.. each key:value pair being a 2 element array I could do something like this:
var key = jsonObj[1][0]; // this would return 'nextKey'
Is there some way to determine the names of the keys ina json object, as if it was an associative array?
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?
How might I go about getting the parsed JSON object in the complete function? The json param shown below seems to just receive the http status text message.
My 2nd question would be how should I knwo if the first place what params I can receive to a callback function like this?
Is there a Jquery method I could use to quickly parse a JSONP object, looking for an embedded object called "error" ?? If I were to do the following: jQuery.each(query.data.error, function(i,error){ //....} And there wasNO .error in the returned JSON, what should I expect to happen? Basically, I want to know if "error" is in the JSON and process accordingly.
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
