I would like my webpage to display what resembles JASON Parser
does (right panel). I first installed JSONView on my Chrome.
Then I composed a string {"isbn":"asdf","name":"qwer","price":1} which I fed to JSON Parser and made sure it indeed obeyed JSON format.
Eventually, I attempted to display it on my webpage by doing:
out.println("{\"isbn\":\"asdf\",\"name\":\"qwer\",\"price\":1}\");
but it was simply displayed like any other normal String instead of being formatted like this.
How do I manage to make my webpage automatically display JSON formatted?
Thanks!
Edit: I didn't realise this was JSP. The answer I'm giving relates to using the JavaScript method JSON.stringify() which you'd somehow achieve within client-side JavaScript within your JSP project.
Use JSON.stringify() to 'pretty-print' the original JavaScript object.
For example, to have two spaces of indentation:
var str = JSON.stringify(obj, null, 2);
If this has to be achieved within Java code then you could use the GSON library. Example: Pretty-Print JSON in Java

My query is that I want to convert html to json with C#. Is there any way to do it. I searched a lot and found articles related to using Javascript Serializer and Newtonsoft to serialize the html string to json. But these serializers do nothing except adding a opening and closing curly braces around the html string. I don't want that. I want to convert whole html to json so that I can get relevant information from the html using C# objects instead of parsing html with regular exressions. Html can be any valid html from any website available on the internet. I am getting the html using http request & response objects using C#.
Please don't suggest using html agility pack because that will also do the same thing that Serialization does.
If anybody have any idea how to do this with C# then please share your ideas.
I will tell why your question can cause confusion.
Consider example of html:
<html>
<body>
<p> example of paragraph </p>
</body>
</html>
Example of json:
{"employees":[
{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}
]}
json is something, on which html is generated or initial fundament. So when you say you want to convert html to json it's really confusing, because it is impossible to figure out according to which rules you want to make this conversion. Or which tags from html should be ignored/added while creating json.
There is a javascript example of the solution here: Map HTML to JSON
DOM Parsers are pretty similar so you can try implementing it in C#. (I'd be interested in such implementation as well :D )
So I am fairly new to working with iOS applications and I am currently working on an application which pulls data from a website using NSURLSessionDataTask, parses the JSON response (HTML), and then populates a view with data from the response.
Currently, I am stuck trying to find a solution to correctly parsing my current HTML string (of type __NSCFString/NSString) from the JSON response, and putting the text into one or more UITextViews and images into one or more UIImageViews within the main ViewController.
It has previously been suggested to simply use a UIWebView to display everything or to use an outside library to do some of the converting, however I am curious if there are any methods by which I could parse the HTML and extract all relevant text or images and throw them into an array for later use. I would very much prefer to keep all of this native and not use outside libraries unless absolutely necessary.
I have also seen some use of the NSAttributedString class for parsing HTML from a JSON response, but am unsure if this is even relevant to what I am trying to do here. Any help/suggestions/thoughts are appreciated!
You can use the native NSXMLParser class. Checkout the documentation here.
Within your custom parsing class. You can generate NSAttributedString and store into array based on custom logic. This should help.
I have a background in data and have just been getting into scraping so forgive me if my web standards and languages is not up to scratch.
I am trying to scrape some data from a javascript component of a website I use. Viewing the page source I can actually see the data I need already there within javascript function calls in JSON format. For example it looks a little like this.
<script type="text/javascript">
$(document).ready(function () {
gameState = 4;
atView.init("/Data/FieldView/20152220150142207",{"a":[{"co":true,"col:"Red"}],"b":false,...)
meLine.init([{"c":100,"b":true,...)
</script>
Now, I only need the JSON data in meLine.init. If I physically copy/paste only the JSON data into a file I can then convert that with jsonlite in R and have exactly what I need.
However I don't want to have to copy/paste multiple pages so I need a way of extracting only this data and leaving everything else behind. I originally thought to save the html source code to R, convert to text and try and regex match "meLine.init(", but I'm not really getting anywhere with that. Could anyone offer some help?
Normally I'd use XML and xpath to parse an html page but in this case (since you know the exact structure you're looking for) you might be able to do it directly with a bit of regular expressions (this is generally not a good idea as emphasized here). Not sure if this gets you exactly to your goal but
sub("[ ]+meLine.init\\((.+)\\)" , "\\1",
grep("meLine.init", readLines("file://test.html"), value=TRUE),
perl=TRUE)
will return the line you're looking for and then you can work your magic with jsonlite. The idea is to read the page line by line. grep the (hopefully) single line that contains the string meLine.init and then extract the JSON string from that. Replace file://test.html with the URL you want to use
Classic problem. Want to see html rendered but I'm seeing text in the browser. Whether I tell handlebars js to decode it or not in template ( three curly braces vs two - {{{myHtmlData}}} vs {{myHtmlData}} ) doesn't get me there. Something about the JSON being returned via the model.fetch() has this html data wrapped up in such a way that it is resistant to the notion of displaying as HTML. It's always considered a string whether encoded or decoded so it always displays as text.
Is this just something backbone isn't meant to do?
The technologies involved here are:
backbone.marionette
handlebars.js
.NET Web API
Your data is being escaped automatically. It's a good thing, but since you're sure the data is a safe HTML. Use {{{}}} as in this other question Insert html in a handlebar template without escaping .
I have an app that builds XML, the text nodes values are coming from the users.
How would I HTML encode that input to avoid bad characters?
Preferably looking for a built in solution in Action Script.
I've used escape() and unescape() for POST variables in the past, not sure if it's the best solution for XML though.
This method seems promising: http://www.markledford.com/blog/2009/02/25/as3-htmldecode-htmlencode-xml-hack/
You can also try converting the string to a textnode as mentioned in How do you encode XML safely with ActionScript 3?
