SerializeObject originObj ; Debug.Oracle Database supports JavaScript Object Notation JSON data natively with relational database features, including transactions, indexing, declarative querying, and views.

Overview of JSON. In this it has much in common with XML. It is a text-based way of representing JavaScript object literals, arrays, and scalar data. A variety of programming languages can parse and generate JSON data.

JSON is relatively easy for humans to read and write, and easy for software to parse and generate. It is often used for serializing structured data and exchanging it over a network, typically between a server and web applications. A JSON value is one of the following: object, array, number, string, or null. All values except objects and arrays are scalar. A JavaScript object is an associative array, or dictionary, of zero or more pairs of property names and associated JSON values.

In JSON each property name and each string value must be enclosed in double quotation marks ". In JavaScript notation, a property name used in an object literal can be, but need not be, enclosed in double quotation marks. It can also be enclosed in single quotation marks '. As a result of this difference, in practice, data that is represented using unquoted or single-quoted property names is sometimes referred to loosely as being represented in JSON, and some implementations of JSON, including the Oracle Database implementation, support the lax syntax that allows the use of unquoted and single-quoted property names.

A JSON number numeral is represented in decimal notation, possibly signed and possibly including a decimal exponent. An object property is often called a field. An object property name-value pair is often called an object member. Order is not significant among object members.

A JSON field name can be empty "". Each field name in a given JSON object is not necessarily unique; the same field name may be repeated.

The JSON path evaluation that Oracle Database employs always uses only one of the object members that have a given field name; any other members with the same name are ignored. It is unspecified which of multiple such members is used. A JavaScript array has zero or more elements. In JSON an array is represented by brackets [] surrounding the representations of the array elementswhich are separated by commas, and each of which is an object, an array, or a scalar value.

Array element order is significant.

Most of the fields have string values. Fields PONumber and zipCode have numeric values: and Field Shipping Instructions has an object as value. This object has three members, with fields nameAddressand Phone. Field name has a string value "Alexis Bull". Fields Address and Phone each have an object value. The value of field Address is an object with fields streetcitystatezipCodeand country. Field zipCode has a numeric value; the others have string values. Field Phone has an array as value.

This array has two elements, each of which represents an object literal. Each of these objects has two members: fields type and number and their values. Field LineItems has an array as value. This array has two elements, each of which is an object. Each of these objects has three members, with fields ItemNumberPartand Quantity. Fields ItemNumber and Quantity have numeric values.The square brackets indicate that it's an array, so your example there is an array containing 2 strings.

As you can see, I'm using 2 functions. When I apply the code you provided it doesn't work. Any ideas? You need to parse the JSON stored in the local storage before outputting each item from the array to the history element. I resolved this problem by moving the History Information Array outside of the clearWatch function. I will ask one more question. Is there anyway to append a localStorage. And if so, how could I incorporate it within my existing code?

You could do it by making a button for each record, making a note of which index that record appears at in the history array maybe as a data attribute on the buttonthen when the button is clicked splice that record from the history array then save and update the record list.

I was investigating various problems with JSON parsing in fluent-bit. There's a lot of other Issues about this, but I felt it'd be useful to get a minimal reproduction, against latest master, and with all the issues I found in one place. Issues I believe are related, at least based on a quick scan:,, As far as I can tell, there's no way currently to configure fluent-bit to correctly parse a JSON string value.

This will work for everything except strings that contain literal backslashes. See below for detail. Alternately, if you want to parse nested JSON, you should apply the json decoder only. All the following is based on commit 00ddwhich is master at time of writing. Here is my config file. I am using the tail input and file output for testing purposes and to keep the tests free of other distractions.

The crux of the whole problem is with how fluent-bit parses JSON values that contain strings. The string tokens returned by jsmn point to the section of the buffer that is between the opening and closing quotes of the string. Note how this substring still contains the escaped newline as a backslash then an n, not as an unescaped actual newline character.

However, the documentation somewhat obliquely indicates that you are meant to use a decoder to rectify this siutation.

If you know in advance exactly what fields you need to apply this to, then we can attempt to use decoders to improve this. However, I'd like to point out that at this point we already are no longer able to process arbitrary JSON objects, since there's no way to apply a decoder to "all string fields" without hard-coding that set of fields in your config file. Any other escaped characters eg.

In addition, this decoder has a somewhat subtle bug. The code loops through each character, checking if it is a backslash and the next char is not in the list of chars that would make it a JSON escape. The next character, of course, is another backslash.

This also gets interpreted as an escape. Turning this minor buffer overflow into a segfault or further business is left as an exercise for the reader. Since fluent-bit keeps string lengths alongside all its strings, the fact that we have an extra NUL terminator doesn't seem to affect things too much.

It shows up in the output, eg. For fields which contain strings intended to be parsed as JSON, eg. One important aspect of this decoder and not documented anywhere as far as I can tell is that it first does a escaped decode on the string before attempting to parse it. However, note that as discussed above, the escaped decoder does not correctly parse unicode escapes. But there are valid albeit pathological JSON documents which will therefore fail to parse, as any character may be replaced with a unicode-escaped version even if it's otherwise valid.

The code is also not capable of outputting non-BMP unicode characters. This could arguably be considered a parsing bug, not an encoding bug. Surrogate pairs are not valid in utf-8 strings, and when these characters are attempted to be encoded, the implementation arguably correctly reports [pack] invalid UTF-8 bytes, skipping and drops those characters. After that, things get trickier. As part of this change, the json decoder should also use this decoding step instead of escapedso it can correctly interpret unicode-escaped characters.

However, none of this deals with the case where the user cannot hard-code in their config file the full list of fields that need to be decoded.US: 1 Remember Me? Forum Ext JS 2.

I am using flot to do some graphing and I am having some trouble passing the tickSize with my json. I am using MVC and pass the json in a model. Here is some code to grab the json within my javascript function:.

json parse special characters

The part that I am having trouble with is "TickSize. I think there is some parsing problem because [] usually means an array. Flot wants the tick size in this format. The issue is the single-quotes in the string value, since you're trying to wrap the JSON string in them as well. The resulting JavaScript will be truncated :. Because of the now 4-count of single-quotes, day isn't actually part of the string and creates a syntax error. It is because you have surrounded the string with ' instead of ".
