Safely turning a JSON string into an object
(28 answers)
Closed 1 year ago.
I have a string that is in a format of a Array, but I need it to be a Array and it has to be a string.
Example Of Data (string):
[{"itemName": "LimitedName", "itemName": "ID", "itemClassName": "ClassName", "MaxAllowed": 1000}]
I need it to become an actual array and be able to add more columns to it as well.
Can someone help me?
You can use JSON.parse(someString)

I have an API returning some JSON and one of the fields is a big integer:
{
"id": 828845277259899344,
"name": "Joe",
"email": "joe#example.com",
...
}
When getting the data with await response.json(), the id is being converted to 828845277259899400. I understand JS can't handle integers that big but I was hoping I could get it as a string instead. Tried to find my way using BigInt but still not there. I couldn't find the answer in similar question here either.

const str: string = `["str1", "str2"]`
how to do it in proper way?
The format you want is a JSON array string. So use the JSON object's stringify function.
JSON.stringify(["some", "array", 123]);

Convert string with commas to array

var array = ["Charizard,Pikachu,Glalie,Delfox"];
I tried to use the split() method except that only affects string variables and not arrays.
My ultimate goal is to make array = ["Charizard","Pikachu","Glalie","Delfox"];
You can retrieve the value of the array an split it using as delimiter the comma ','
var array = ["Charizard,Pikachu,Glalie,Delfox"];
console.log(array[0].split(','))

Having a string like:
"*this* not that"
I can select *this*
\*(.*?)\*
but I'm not able to get only this.
what I am trying to achieve is to replace -this- by a new string. What's the easiest way to do that ?
you can try:
"*this* not that".replace(/\*.*\*/,'*new_string*');
//"*new_string* not that"

How can I get query string values in JavaScript?
(73 answers)
Closed 9 years ago.
Given the following string/query string:
ajax/hovercard/hovercard.php?id=100000472545907&extragetparams=%7B%22hc_location%22%3A%22stream%22%7D
What is the best way to extract the id?
Try this:
yoururl.match(/id=(.*)&/)[1]
Fiddle
params = location.search.substring(location.search.indexOf('id')).split('&')[0]
id = params.substr(3)
If it is always shipped in this exact order - then
url.match(/\d+/)
otherwise
url.match(/id=(\d+)/)
