Convert a multidimensional javascript array to JSON?
(9 answers)
Closed 2 years ago.
I have an array of arrays which I have planted in the DOM, so that I can reuse it at a later stage to transfer to the server:
[["1","aaaaaa","1"],["2","bbbbbbb","2"],["3","ccccccc","3"]]
If I would like to convert it back into a Javascript array, how would I go about doing this?
var obj = $.parseJSON('[["1","aaaaaa","1"],["2","bbbbbbb","2"],["3","ccccccc","3"]]')
Assuming jquery is ok to use because of tag.
If the browzer has the JSON object then
JSON.parse(string);
or if you have jQuery
$.parseJSON(string);
var array = JSON.parse(my_JSON)
jQuery.parseJSON()
var myArr = $.parseJSON(myJsonString);

How do I loop through or enumerate a JavaScript object?

Im seeing a lot of answers to this in simple arrays but I need the keys and value. I have a json object but need an array. The object looks like this:
{"Food":"Starbucks", "Job":"Electrician"}
I just need a simple array like this:
["Food" => "Starbucks", "Job" => "Electrician"]
Edit: Im not sure how to type it out. Just need to be able to do an array.map and get the keys and values in javascript.
Here is the final code that I am trying:
const details = jsonObject;
{details.map(function(item,idx){
return<DetailCell>
<Label>{idx}</Label>
<Text style={TextStyle}>{item}</Text>
</DetailCell>
})}
Label should be the key and the Text should be the value.
I think you need this :
[{"Food" : "Starbucks"}, {"Job" : "Electrician"}]
To declare a literal array value is something like this in JSON in node.
{JSONVarWithArrayValue : [0,0,0,0]}

I am new to stack overflow learning javascript and programming.
I have a problem that i am stuck while learning and thinking any help on this question will be
useful for me thanks and the question is:
Example i have a variable a in the code below and i want to convert it to an array in javascript
var a = ["baby,cat,dog"]
i wanted it to be
a = ["baby","cat","dog"].
Use String.prototype.split() as below
var a = ["baby,cat,dog"];
a = a[0].split(',');
console.log(a);
You could take the array and map the splitted values and get a flat array back.
var array = ["baby,cat,dog"];
result = array.flatMap(s => s.split(','));
console.log(result);

I want to turn this into an array
"["65747add-afd2-45b5-92e0-150bbe40e6d9", "9c247ea5-6b81-4f47-a50c-42367dedd50b", "c1555363-aca9-4e04-8844-e0180397c72e"]"
I am getting it from the page like this:
$('#layout-uuids').text()
Is there away to just get it as an array or do I need to turn the string into an array somehow?
Thanks!
That string looks like JSON. If it is indeed JSON, all you need is JSON.parse():
var someArray = JSON.parse($('#layout-uuids').text());

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.

I have this type of JSON:
{"value":[{"idProductCategoryAttributeValue":43,"value":"7","sortOrder":0}]}
I want the individual parameters values like. How do I parse this JSON string in Ext JS 4 or in simple JavaScript?
Have a look at http://docs.sencha.com/ext-js/4-1/#!/api/Ext.JSON. There you find how you can parse JSON with Ext JS 4.
var strJson = '{"value": [{"idProductCategoryAttributeValue":43,"value":"7","sortOrder":0}]}';
var obj = Ext.JSON.decode(strJson);
var obj = Ext.decode(jsonstr);
