How to capture the value of data attribute? - javascript

The javascript snippet that we have is :
Link
I would like to retrieve the value of data-test-socialmedia type. Based on that I would like to add the conditional statement to check if the data-test-socialmedia type is facebook. As we have many data attributes like this in the site.
I tried several ways and I get object as the value. But i need the actual value in this case it is facebook. Kindly help.


//first get element
var el = document.getElementsByClassName('n-contact')[0];
//get data and replace single quotes with double quotes to create valid JSON
var d = el.dataset.testSocialmedia.replace(/'/g, '"')
//parse JSON to javascript object
var parsed = JSON.parse(d, null)
//get country if type is facebook
if(parsed.options == 'facebook')
console.log(parsed.options.country)
Link


var str = document.querySelector('.n-contact').getAttribute('data-test-socialmedia').replace(/'/g,'"');
var obj = JSON.parse(str);
var result = obj.type;
console.log(result);
it would work.


With jQuery
var elementData = $(".n-contact").attr("data-test-socialmedia").replace(/'/g,'"'),
parsed = JSON.parse(elementData);
console.log(parsed);

Nightwatch.js - Can't figure out how to pass a local variable into a URL parameter

I have tried both options, but nothing seems to work:
var webNum = browser.getText('selector');
var urlGo = 'https://gotourl.com/' + webNum;
browser.url(urlGo);
or
var webNum = browser.getText('selector');
browser.url('https://gotourl.com/' + webNum);
Any ideas?

.getText() is returning a WebElement JSON Object rather than string (the documentation on nightwatch api is misleading...)
The text you want is the value of the WebElement JSON Object, and you can access it by using .value
if you would like to get the text you have to do the following :
var webNum = 'nothing';
browser.getText('selector',function(text){
webNum=text.value;
var urlGo = 'https://gotourl.com/' + webNum;
browser.url(urlGo);
});
This way should works.

How to get the "typeof" in JavaScript for a json message

When i try to get the type of an element using the below code it works.
var bodyContent = JSON.parse(response.content);
response.content = typeof bodyContent.CompanyList.Company.Name;
Output response for above was String
Whereas if i try it in the below approach this does not work for the same JSON message. Please help
var bodyContent = JSON.parse(response.content);
var nameHolder = "CompanyList.Company.Name";
response.content = typeof bodyContent[nameHolder];
Output was undefined

That's because it's a nested object, you can't just pass a period delimited name and have it recursively drill down the tree (you'll have to implement that yourself).
It's the difference between
bodyContent["CompanyList"]["Company"]["Name"]; // former
and
bodyContent["CompanyList.Company.Name"]; // latter

There are 2 solutions for this issue.
You have to parse the nameHolder path. Reference: Accessing nested JavaScript objects with string key
or use eval but I'll not write about this since it's not a good practise.

It looks for a property called "CompanyList.Company.Name".
This works:
var bodyContent = JSON.parse(response.content);
var list = "CompanyList";
var company = "Company";
var name = "Name";
response.content = typeof bodyContent[list][company][name];

JSON rows Extracting issue in JavaScript

I have following json data coming from server in which i want to extract LimitClass and LimitClassID and store their values in respective arrays.
{
"ErrorDesc":"",
"ErrorCode":"",
"LimitClassList":"[{\"LimitClass\":\"L16\\n\",\"LimitClassId\":\"32900\\n\"},{\"LimitClass\":\"28febL0\\n\",\"LimitClassId\":\"31901\\n\"},{\"LimitClass\":\"L14\\n\",\"LimitClassId\":\"31900\\n\"},{\"LimitClass\":\"L17\\n\",\"LimitClassId\":\"32950\\n\"},{\"LimitClass\":\"L15\\n\",\"LimitClassId\":\"31950\\n\"},{\"LimitClass\":\"L0\\n\",\"LimitClassId\":\"21901\\n\"},{\"LimitClass\":\"L4\\n\",\"LimitClassId\":\"23000\\n\"},{\"LimitClass\":\"OTC Send\\n\",\"LimitClassId\":\"30901\\n\"},{\"LimitClass\":\"L2\\n\",\"LimitClassId\":\"22900\\n\"},{\"LimitClass\":\"L12\\n\",\"LimitClassId\":\"28900\\n\"},{\"LimitClass\":\"L6\\n\",\"LimitClassId\":\"23900\\n\"},{\"LimitClass\":\"L1\\n\",\"LimitClassId\":\"25900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"29900\\n\"},{\"LimitClass\":\"L7\\n\",\"LimitClassId\":\"24900\\n\"},{\"LimitClass\":\"L8\\n\",\"LimitClassId\":\"26900\\n\"},{\"LimitClass\":\"L10\\n\",\"LimitClassId\":\"27900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"30900\\n\"},{\"LimitClass\":\"UatTesting123\\n\",\"LimitClassId\":\"32901\\n\"}]"
}
Here is the code I have tried :
var list = data.LimitClassList;
var arrayLimitClass = [];
var arrayLimitClassId = [];
for(var i in list) {
arrayLimitClass.push(list[i].LimitClass);
arrayLimitClassId.push( list[i].LimitClassId);
}
alert(list);
alert(arrayLimitClass);
alert(arrayLimitClassId);
List variable has following result when I alert it:
[{\"LimitClass\":\"L16\\n\",\"LimitClassId\":\"32900\\n\"},{\"LimitClass\":\"28febL0\\n\",\"LimitClassId\":\"31901\\n\"},{\"LimitClass\":\"L14\\n\",\"LimitClassId\":\"31900\\n\"},{\"LimitClass\":\"L17\\n\",\"LimitClassId\":\"32950\\n\"},{\"LimitClass\":\"L15\\n\",\"LimitClassId\":\"31950\\n\"},{\"LimitClass\":\"L0\\n\",\"LimitClassId\":\"21901\\n\"},{\"LimitClass\":\"L4\\n\",\"LimitClassId\":\"23000\\n\"},{\"LimitClass\":\"OTC Send\\n\",\"LimitClassId\":\"30901\\n\"},{\"LimitClass\":\"L2\\n\",\"LimitClassId\":\"22900\\n\"},{\"LimitClass\":\"L12\\n\",\"LimitClassId\":\"28900\\n\"},{\"LimitClass\":\"L6\\n\",\"LimitClassId\":\"23900\\n\"},{\"LimitClass\":\"L1\\n\",\"LimitClassId\":\"25900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"29900\\n\"},{\"LimitClass\":\"L7\\n\",\"LimitClassId\":\"24900\\n\"},{\"LimitClass\":\"L8\\n\",\"LimitClassId\":\"26900\\n\"},{\"LimitClass\":\"L10\\n\",\"LimitClassId\":\"27900\\n\"},{\"LimitClass\":\"L13\\n\",\"LimitClassId\":\"30900\\n\"},{\"LimitClass\":\"UatTesting123\\n\",\"LimitClassId\":\"32901\\n\"}]
But I am getting dots (.) when I alert arrayLimitClass and arrayLimitClassId. What am I doing wrong in extracting rows of json Object?

"LimitClassList":"[{\"LimitClass\":\"L1....]"
^ ^
LimitClassList is a string, not an array. Make it so it is an actual array, than your code should work. There should be no reason to have to parse it again.

The value below data.LimitClassList is itself a String containing JSON. You have to decode this first.
var list = JSON.parse( data.LimitClassList );
var arrayLimitClass = [];
var arrayLimitClassId = [];
// ...
This is more or less a workaround. You should have a look at your server code and fix the encoding error there!

Javascript: save way to read GET without PHP

I know about GET variables and javascript there are many questions, but I do not understand or get them to work.
I have a html formular, and I need to populate a field with the value of the get variable. The url has 2 variables, here an example:
?pid=form.html&id=9869118
This page is a html only, so I cannot use php, but I want to (firstly) alert, the value of id.
I have tried so many different versions of solutions here and from google.
(For example:
http://www.onlineaspect.com/2009/06/10/reading-get-variables-with-javascript/
Please help me to understand how its done correctly and save! Please note, I have no jquery either.
Here is what I have tried so far. This is inside the <script> tags inside my form.html
var GETDATA = new Array();
var sGet = window.location.search;
if (sGet)
{
sGet = sGet.substr(1);
var sNVPairs = sGet.split("&");
for (var i = 0; i < sNVPairs.length; i++)
{
var sNV = sNVPairs[i].split("=");
var sName = sNV[0];
var sValue = sNV[1];
GETDATA[sName] = sValue;
}
}
if (GETDATA["id"] != undefined) {
document.forms.otayhteytta.id.value = GETDATA["id"];
}

Take a look at this excellent javascript url manipulation library:
http://code.google.com/p/jsuri/
You can do stuff like this:
Getting query param values by name
Returns the first query param value for the key
new Uri('?cat=1&cat=2&cat=3').getQueryParamValue('cat') // 1
Returns all query param values the key
new Uri('?cat=1&cat=2&cat=3').getQueryParamValues('cat') // [1, 2, 3]

You can use a pure JavaScript function for that like so:
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
And then you can alert the value of 'id' like so:
alert(getParameterByName('id'));
You can check if the parameter exists using a simple 'if' condition:
var id = getParameterByName('id');
if (id != "") {
alert(id);
}
Source: How can I get query string values in JavaScript?

A simple way to get the GET parameters without using a library:
var parameters = []
var parts = location.search.substr(1).split('&')
for(var part in parts) {
var splitted = parts[part].split('=')
parameters[splitted[0]] = splitted[1]
}
Now parameters is an array with the parameter name in the key and the value as the value.
This is a simple solution and may not work for all scenario's.

Using array returned by String.split

data = 'numbersXXXtext';
or
data = 'XXXtext';
var get = data.split('XXX');
var sum = get[1];
I would like get always "text". If data equals numbersXXXtext, the code works fine, but if data is XXXtext then get[1] is undefinded.
Does anyone know how I can solve this?

If there is only one occurrence of XXX in the string, the bit you want will always be the last item in the array returned by split. You can use pop to get the last item of an array:
var a = "numbersXXXtext";
var b = "XXXtext";
console.log(a.split('XXX').pop()); // "text"
console.log(b.split('XXX').pop()); // "text"

Try this:
var sum = get.length > 1 ? get[1] : get[0]

Strange, i just tried your code, and it's working. (http://writecodeonline.com/javascript/)
Are you sure you are not missing something?
data = 'numbersXXXtext';
//data = 'XXXtext';
var get = data.split('XXX');
document.write(get[1]);
document.write("</br>");
document.write(get);
document.write("</br>");
I didn't get undefined in neither of your strings

An alternative using substring:
var data = 'numbersXXXtext';
var value = data.substring(data.indexOf('XXX') + 'XXX'.length);
