Folloing working for me in javascript for notification alert("message onclick"); this way i want to pass json string message in push notification , i dont know how to pass this please help me. i want something like this,
alert("\{"action":"com.example.dictionarylib.notification.UPDATE_STATUS", "alert":"hello""\}");
but i dont know actual sysntax of passing json, please give me right way to pass this.
As I understand you need a function which will convert your JSON object to String.
There is function called stringify you can use for that.
Here is the documentation on stringify function.
And here is the usage example:
var json = {
"action": "com.example.dictionarylib.notification.UPDATE_STATUS",
"alert": "hello"
};
alert(JSON.stringify(json));

How can I access and process nested objects, arrays, or JSON?

So i want to get a value from a json file, but for the life of it, i cant get to understand what to write.
So if someone could help me write this line of code in javascript node, i would be grateful.
I am trying to get the value of "totalCount"
This is from a library called GeoDb just for context.
main.js(NODEjs)
const timezone = require("./TimezonePortugal.json"); //referencing the json
console.log(timezone.metadata); // i dont know what to say afther this
TimezonePortugal.json
{"data":[{"code":"EUR","countryCodes":["PT","YT","IE","AD","IT","AT","RE","AX","BE","BL","SI","SK","SM","CY","DE","LT","LU","LV","MC","ME","MF","EE","MQ","MT","VA","ES","NL","FI","FR","GF","GP","GR","PM"],"symbol":"€"}],"metadata":{"currentOffset":0,"totalCount":1}}
"." means inside.
If you want to get value of totalCount you have to think like this:
timezone.metadata.totalCount = totalCount inside the metada, metadata inside the timezone
For example:
var timezone=
{
"data":[
{
"code":"EUR",
"countryCodes": ["PT","YT",],
"symbol":"€"
}
],
"metadata": {
"currentOffset":0,
"totalCount":1
}
}

read an external local JSON file into Javascript
(4 answers)
Closed 3 years ago.
I have an external JSON file on my server that I want to display the objects from into an HTML document without using JQuery. I specifically just want to call the username object and display it on an "All Users" page for a simple homework project. I've had a difficult time finding ways to do this without JQuery. How could I go about doing this?
JSON Example:
{"name":"asfd","username":"awsf","email":"kean","age":"21","gender":"Male","submit":"Submit"},
{"name":"asdf","username":"asfd","email":"asdf#asdf","age":"21","gender":"Male","submit":"Submit"},
{"name":"null","username":"null","email":"null#gmail.com","age":"21","gender":"Male","submit":"Submit"},
{"name":"null","username":"null","email":"null#gmail.com","age":"21","gender":"Male","submit":"Submit"},
If you have an array of json objects you can loop over it and call JSON.parse() on each. That will give you simple user object that you can access and place in your page his username.
for(var i=0; i<users.length; i++) {
var user = JSON.parse(users[i]);
// you can now access username for each user with user[i].username
// place a username into new element in your page
}

Serialize javascript object to json and back
(4 answers)
Closed 7 years ago.
I need to serialize an object to JSON, in javascript.
How I can do it? I google it, but im not found the solution.
All the response are "You mustn't serialize Json in javascript, you must serialize in other language as Java, C#, so on"
Without use JQuery.
Checkout JSON.stringify() and JSON.parse() in JSON2 documentation
Example:
myData = JSON.parse(text); // from json string to js object
var myJSONText = JSON.stringify(myObject, replacer); // js object to json string

How can I access and process nested objects, arrays, or JSON?

Hi friends I have a I have a json string as shown below. How to parse the string to get day,min_amount,max_amount values .
[{"day":"1970-01-01","min_amount":"0.00","max_amount":"0.00"},{"day":"1970-01-02","min_amount":"1.00","max_amount":"2.00"}]
Just use JSON.parse. The syntax for accessing a value is simple:
obj = JSON.parse(json)
day = obj[0].day
min_amount = obj[0].day
max_amount = obj[0].day
The great thing about Javascript is how simple it is to use JSON, because JSON is just a serialized version of plain-old javascript hashes, arrays, and scalars.
It's already in object form. SO use this :
var x = [{"day":"1970-01-01","min_amount":"0.00","max_amount":"0.00"},{"day":"1970-01-02","min_amount":"1.00","max_amount":"2.00"}]
jQuery.each(x,function(e){
console.log(x[e])
console.log(x[e].day)
});
Here is the working example : http://jsfiddle.net/u6J8A/
As you may not have noticed, JSON is JavaScript synthax.
<script type="text/javascript">
var data = [
{"day":"1970-01-01","min_amount":"0.00","max_amount":"0.00"},
{"day":"1970-01-02","min_amount":"1.00","max_amount":"2.00"}
];
</script>
Dumping it directly in the JavaScript code is perfectly valid.
But if you are fetching this data at run time and have the information as a string, you can convert it using JSON.parse(string).
The information can be then read from this structure by the variables data[0].day, data[0].min_amount, data[0].max_amount, data[1].day, data[1].min_amount, data[1].max_amount.

How can I access object properties containing special characters?
(2 answers)
Closed 9 years ago.
I want to read data in the javascript which are received from the server in JSON format.
I've been using this a lot but now it seems that I hit the wall with this example:
JSON
{
"results": [
{
"MIN(jtable.HIT_VALUE)": "70.200000",
"AVG(jtable.HIT_VALUE)": "124.4077234969",
"MAX(jtable.HIT_VALUE)": "1854.620000"
}
]
}
JAVASCRIPT
How to read this values?
I have tried this
response.results[i].MIN(jtable.HIT_VALUE)
and I'm getting this error:
TypeError: Object #<Object> has no method 'MIN'
Any ideas?
MIN(jtable.HIT_VALUE) is the key and has to be used as such using the square bracket notation like
response.results[i]['MIN(jtable.HIT_VALUE)']
Use it as string:
response.results[i]['MIN(jtable.HIT_VALUE)']
JavaScript interprets the call response.results[i].MIN(jtable.HIT_VALUE) as an attempt to call a nonexistent function MIN.
Consider using this:
response.results[i]["MIN(jtable.HIT_VALUE)"]
