Get all match values from two comma separated string

I have two comma separated string as follows,
var hiddenString = '14172,10062,14172,14172,100,10,14172,15000,12000';
var strB = '14172,10062,10064,10025,100,14182';
I need to create another string based on the above two,
if hiddenString have unmatching value with strB,then without those unmatched values need to create e new string and also avoid duplicates.
simply says, I need to get all the matching values from both strings.
As the example based on my two string, I'm expecting the following:
varFinalHiddenString = 14172,10062,100;
How can I do this using JavaScript and that should work in safari and IE 11 or its earlier versions. Please help me, I'm new to the JS.

You can first split() strings to generate arrays from them. Then filter() the smaller array by checking the index of the current item with indexOf() in other array:
var hiddenString = '14172,10062,14172,14172,100,10,14172,15000,12000';
var strB = '14172,10062,10064,10025,100,14182';
var temp1 = hiddenString.split(',');
var temp2 = strB.split(',');
var varFinalHiddenString = temp2.filter(function(s){
return temp1.indexOf(s) > -1;
}).join(',');
console.log(varFinalHiddenString);

Make arrays of the strings, then use the "filter" method. Then convert back to string.
var hiddenString = '14172,10062,14172,14172,100,10,14172,15000,12000';
var strB = '14172,10062,10064,10025,100,14182';
var hiddenStringAsArray = hiddenString.split(',');
var strBArray = strB.split(',');
var resultObject = $(strBArray).filter(hiddenStringAsArray);
var resultArray = resultObject.toArray();
var resultString = resultArray.join(',');
console.log(resultString);

replace string in json

I am new to javascript and have this code which will replace the string from A to B, but if there is multiple records of As, it will only replace the first A, while the remaining will be remain as A. Note that the stringify is called twice.
"success": function(json) {
var old = JSON.stringify(json).replace('"新交易"', '"待审核"');
var newdata = JSON.parse(old);
var old = JSON.stringify(newdata).replace('"批准"', '"已充值"');
var newdata = JSON.parse(old);
fnCallback(newdata);
}

This has little to do with JSON. As documented:
To perform a global search and replace, include the g switch in the regular expression.
So change this:
replace('"新交易"', '"待审核"')
... into this:
replace(/"新交易"/g, '"待审核"')

To replace every word in your context use Regular Expressions. So check this example to see how it works:
var someText = '"新交易""新交易""新交易""新交易""新交易""新交易""新交易""新交易"';
var someText2 = '"批准""批准""批准""批准""批准""批准""批准""批准""批准""批准"';
var old = someText.replace(/"新交易"/g, '"replaced"');
var stuff = someText2.replace(/"批准"/g, '"已充值"');

making JSON from string

I have a job to refractor strings to start using json so they can just pass json objects. So I have made array of names and then I'm trying to go through and make key and values but I'm getting an error in the console that it cant find x of no value. Can someone point me in the right direction?
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification', 'WorkQueue', 'TicketState',................ to long to post];
$().each(newName, function (key, value) {
key = newName[this];
value = newValues[this] = $('#' + key).val();
newArray = [key][value];
newArray = JSON.stringify(newArray);
alert(newArray);
$('.results').html(origArray[TicketNumber]);
});

I'm assuming you have "newValues" and "origArray" defined elsewhere?
In any case you'll need to at least adjust the following:
"$().each" should be $.each
"newArray" should be defined outside and you should use newArray[key] = value
you don't have a variable "TicketNumber" defined and so you should wrap "TicketNumber" in quotes
this is a reserved word so you shouldn't use it in "newName[this]" or "newValues[this]"
I suggest using a for loop instead of $.each() based on what you're trying to do inside.
https://msdn.microsoft.com/en-us/library/bb299886.aspx

var origArray = [];
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification'
];
for (var i = 0; i < newName.length - 1; i++) {
var object = {};
object[newName[i]] = newName[i];
object = JSON.stringify(object);
origArray.push(object);
}

Javascript JSON stringify No Numeric Index to include in Data

i am trying to pass non numeric index values through JSON but am not getting the data.
var ConditionArray = new Array();
ConditionArray[0] = "1";
ConditionArray[1] = "2";
ConditionArray[2] = "3";
ConditionArray['module'] = "Test";
ConditionArray['table'] = "tab_test";
var Data = JSON.stringify(ConditionArray);
When i alert the Data Variable it has the Values 1,2 and 3 but module and table are not included. How can this be added so that the whole string is passed.
EDIT : And what if i have some multidimensional elements also included like
ConditionArray[0] = new Array();
ConditionArray[0] = "11";

JSON structure only recognizes numeric properties of an Array. Anything else is ignored.
You need an Object structure if you want to mix them.
var ConditionArray = new Object();

This would be an better approach:
var values = {
array : ["1", "2", "3"],
module : "Test",
table : "tab_test"
};
var data = JSON.stringify(values);

Since javascript array accepts numeric index only. If you want non numeric index,use Object instead.
var ConditionArray = {};
ConditionArray[0] = "1";
ConditionArray[1] = "2";
ConditionArray[2] = "3";
ConditionArray['module'] = "Test";
ConditionArray['table'] = "tab_test";
var Data = JSON.stringify(ConditionArray);
Here is the working DEMO : http://jsfiddle.net/cUhha/

According to the algorithm for JSON.stringfy (step 4b), only the (numeric) indices of arrays are stringified.

This is because Array does not contain your elements.
When you do this:
ConditionArray['module'] = "Test";
You actually add a property to the ConditionArray, not elements. While JSON.stringify converts to string only elements of the ConditionArray. For example:
var arr = new Array;
arr['str'] = 'string';
console.log(arr.length) //outputs 0
You need to use an Object instead of Array

If you change the first line to
var ConditionArray = new Object();
you will achieve the desired outcome.

If for some reason you cannot convert your array into object, for instance you are working on a big framework or legacy code that you dont want to touch and your job is only to add som feature which requires JSON API use, you should consider using JSON.stringify(json,function(k,v){}) version of the API.
In the function you can now decide what to do with value of key is of a specific type.

this is the way how I solved this problem
Where tblItemsTypeform is array and arrange is de index of the array
:
let itemsData = [];
for(var i = 0; i <= this.tblItemsTypeform.length -1;i++){
let itemsForms = {
arrange: i,
values: this.tblItemsTypeform[i]
}
itemsData.push(itemsForms)
}
And finally use this in a variable to send to api:
var data = JSON.stringify(itemsData)

Convert string to become variable

I have multiple variables containing JSON as string (received from AJAX).
data.output_data_1234
data.output_data_5678
I convert them to Array:
var outputdataarr = new Array(data.output_data_1234);
This works fine, but how do I add a number to the var name:
var outputdataarr = new Array('data.output_data_'+formid+'');
this one does not work.
formid contains a proper number.
This does not work too:
var outputvar = window['data.output_data_' + formid];
var outputdataarr = new Array(outputvar);
Please help. Thanks.

You probably mean, you need something like this:
var outputdataarr = new Array(data['output_data_'+formid]);
You can only use string in square brackets as an object field identifier. It cannot contain '.'.
UPDATE:
However, you will probably need a loop to fill the whole array, e.g.
var outputdataarr = new Array();
for (var i=1000; i<2000; i++) {
outputdataarr.push(data['output_data_'+formid]);
}

Use [] instead of new Array is better.
var outputdataarr = [];
outputdataarr.push(data['output_data_'+formid]);
//and so on
