Retrieve data from JSON file and display images in a gallery

由 扶醉桌前 提交于 2019-11-29 16:25:25
问题 I'm new to JQuery and any help would be much appreciated. "Using $.getJSON function, retrieve the data in the items.json file provided and display the images in a gallery below. The gallery should display each image at roughly thumbnail size with its caption below it in a 3-column grid at desktop resolution." I was able to get the the .json to output on the HTML page, now I was wondering how to get the actual images to show on the HTML page instead of the URL path of the images? This is what

I'm having a problem with method using $.getJSON. It's very simple and it looks like that: function lastID(query) { $.getJSON(url+query ,function(json){ var type_id = json.data; }); return type_id // doesn't work } Could you please tell me how to return type_id to some other value for instance like this: var returnedID = lastID(query); // this schould me equal to returned type_id from lastID method.

I am trying to retrieve the exchange rate from Google with jQuery's $.getJSON() . Using the request: "http://www.google.com/ig/calculator?hl=en&q=1USD=?CAD" returns a simple JSON file: { lhs: "1 U.S. dollar", rhs: "1.03800015 Canadian dollars", error: "", icc: true } I am using the following jQuery function to get the Canadian dollar amount: $(document).ready(function(){ $.getJSON("http://www.google.com/ig/calculator?hl=en&q=1USD=?CAD?&label=rhs&format=json&jsoncallback=?", function(data){ alert(data); }); }); </script> Fire bug displays the correct JSON file but indicates that an invalid

JQuery's getJSON() not setting Accept header correctly?

由 ε祈祈猫儿з 提交于 2019-11-29 06:34:13
It looks like people have had issues with Accept headers in the past, but I'm not sure my issue is related. Using jQuery 1.4.2, I'm having trouble getting JSON with getJSON() . I can watch the request / response in Firebug and it looks like the source of the problem is that the resource in question returns different results depending on the Accept header. Even though the docs say it should be set, in Firebug it shows up as " / " -- obviously, I want "application/json". Is this a known bug? Am I supposed to be setting some flag I'm not aware of? ETA: The request is cross-site, if that matters,

Max recommended size of external JSON object in JavaScript

由 好久不见. 提交于 2019-11-29 03:51:21
I have a tremendous amount of data to sort and query, and I can't rely on an internet connection. Ideally, I'd like to store my entire data-set as a JSON object (currently around 17MB, but could get much larger) and use something like jLinq or SQLike to query it, as opposed to having to output numerous smaller files. I'm interested in finding what the largest recommended filesize is for an external getJSON call using JavaScript (jQuery, specifically). 1MB, 20MB, 100MB? Information on the subject is scarce. Information on querying large data-sets client-side is scarce all around. Any

How to read json response as name value pairs in JQuery

由 大憨熊 提交于 2019-11-29 02:21:23
I want to read json response as name and value pairs in my JQuery code. Here is my sample JSON response that I return from my java code: String jsonResponse = "{"name1":"value1", "name2:value2"}; in my JQuery, if I write jsonResponse.name1 , I will get value as "value1" . Here is my JQuery code $.ajax({ type: 'POST', dataType:'json', url: 'http://localhost:8080/calculate', data: request, success: function(responseData) { alert(responseData.name1); }, error: function(XMLHttpRequest, textStatus, errorThrown) { //TODO } }); Here I want to read "name1" from jsonResponse instead of hardcoding in

Assign data from jQuery getJSON to array

由 风流意气都作罢 提交于 2019-11-29 00:31:27
How do you assign the data fetched via getJSON() to an array, for later use? The getJSON url below retrieves properly formatted JSON with 10 main elements, each having subelements of id, username, haiku (and other). If you're running it, try saving the JSON elements to a local file, so you won't get the same domain error (i.e., JSON will not load if you're fetching from a different domain). What happens is that the alert will fetch a value within the getJSON callback, but outside, the value is undefined. $(document).ready(function(){ var haikus=[]; alert("begin loop"); $.getJSON('http:/
