Call function if variable does not exist in a filter

seems to work fine Check if any items are left in the array after the filter is complete:
if (this.productService.list.length) {
  // The user's query was found in the array
} else {
  // The user's query was not found in the array

How do I properly call a C# variable in Jquery. The 'variable name' does not exist in the current context

Hope that helps I am storing a couple of values in my codebehind as a via Request.QueryString like so: , I ran into this issue earlier this year. Try this out Skullomana

Swift: cannot convert value of type to @noescape while call indexOf, after filter using filter function

Tag : arrays , By : user134570

To fix this issue The indexOf method on Swift arrays does not take an object of a type matching the array's type. Instead, it takes a closure. That closure takes an element of the array's type and returns a bool.
So, in fact, we don't (and shouldn't) even bother with the filter call unless we actually need the resultant array. If we're just looking for the first object that passes whatever test you are filtering for... well we just pass that exact same test to indexOf.
let letters: [String] = ["x", "y", "z", "a", "b", "c"]

let index = letters.indexOf {
    $0 == "a"

Why does the filter function exist?

With these it helps Way, way back in the day, way before we had list comprehensions, some guy who liked functional programming wrote up map and filter and submitted the change, and it got put in. That's about it.

Call script only if a GET variable doesn't exist in URL

Tag : javascript , By : Liviu Aileni

I hope this helps . I've been investigating that issue ever since I posted that message, and I just can't get PHP to read my $_GET variables properly despite testing a ton of things. I couldn't identify the reason, and since no one's been able to help, here's how I ended up working around the issue in jQuery:
var $_GET = {};

document.location.search.replace(/\??(?:([^=]+)=([^&]*)&?)/g, function () {
    function decode(s) {
        return decodeURIComponent(s.split("+").join(" "));

    $_GET[decode(arguments[1])] = decode(arguments[2]);

//If variable "dnt" is defined, bypass Google Analytics
if(typeof $_GET["dnt"] == 'undefined')
    var gA = "<script src='https://www.google.com/recaptcha/api.js'><\/script><script async src='https://www.googletagmanager.com/gtag/js?id=my_id'><\/script><script>window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);}gtag('js', new Date());gtag('config', 'my_id');<\/script>";
