This function below doesn’t work like I want it to; being a JS novice I can’t figure out why. I need it to wait 5 seconds before checking whether the newState is -1. Currently, it doesn’t wait, i...
var linkElement = document.getElementById("BackButton"); var loc_array = document.location.href.split('/'); var newT = document.createTextNode(unescape(capWords(loc_array[loc_array.length-2]))); linkElement.appendChild(newT); Currently it takes the second to last item in the array from the URL. However, I want to do a check for the last item in the array to be "index.html" and if so, grab the ...
I'm using JSLint to go through JavaScript, and it's returning many suggestions to replace == (two equals signs) with === (three equals signs) when doing things like comparing idSele_UNVEHtype.value.
Novice JavaScript developers need to know that the "not not" operator is using implicitly the original loose comparison method instead of the exact === or !== operators and also the hidden cast operation that is happening behind the scenes and I show it in the example I provide.
In all other cases, you're safe to use ==. Not only is it safe, but in many cases it simplifies your code in a way that improves readability. I still recommend Crockford's talk for developers who don't want to invest the time to really understand Javascript—it's good advice for a developer who only occasionally works in Javascript.
Javascript does have types; and in any case, how is the dollar sign even related to that? It's just a character that happens to be a legal identifier in Javascript.
How do I display the content of a JavaScript object in a string format like when we alert a variable? The same formatted way I want to display an object.
