Wondering why my js code isnt referencing the linked .js files I added? I used this on CodePen by linking them through their site, but when I try to add the refrences manually it doesnt seem to work. I tried the suggestions on this page Why does jQuery or a DOM method such as getElementById not find the element? as well but nothing worked. Any thoughts?

So I'm trying to make a game where people can change their display name and then store it in a JSON file so that other files and pages can access it. So I added an XMLHttpRequest but I then read this article and wondered whether I actually need the XMLHttpRequest. I will attach the JavaScript and JSON files to give a bit more context.

Based off a simlar question asked here - How to convert a currency string to a double with jQuery or Javascript?, I need to take a currency that can be in the format of

-143,000.00 and convert it for 2 scenarios:

1. Where the output would be -143000.00
2. Where the output would be -1430000

I want to dynamically print values and strings on my Twig template using JavaScript code. But it doesn't work.

Also when I load the Twig template, it should show the contents of the "test" on page, which is just "asdasd".

But it doesn't work. What I get is nothing, as if no script code exists.

I have a form with Javascript, which works as expected:

I created a snippet based on .parents() without jquery - or querySelectorAll for parents

I need to change value of textarea(commnet box of instagram.com) through a chrome extension's script(content script) so that its react prop "value"(this.props.value) changes and on triggering submit event on the parent form element the comment get posted.

If I trigger the event after changing the textarea's value with $commentBox.value = "comment" and then trigger submit event on the form element the comment doesnt get posted and I checked through react devtools that prop value is "". I think prop value changes only on keydown/keypress but faking keydown/keypress after changing the value also doesnt work

how can I insert the comment through javascript and then post it? also see this SO post

I'm following this standard pattern for using Ajax to reload a partial view. However, when the partial view is reloaded, the controls in the view have different IDs. They lose the name of the parent model. This means that when the form is posted back, model binding won't work.

So in the example below, when the page is first loaded, the checkbox id is "PenguinEnclosure_IsEnoughPenguins" but after the partial is reloaded, the checkbox id is "IsEnoughPenguins" The ID must be "PenguinEnclosure_IsEnoughPenguins" for model binding to correctly bind this to the PenguinEnclosure property of the VM.

I am currently working on a booking application project. I want to sort the itineraries created based on their time range, does anyone know how to sort multiple ranges of time in javascript/jquery?

For example, I have the ff. range of time (Each range should be considered as one object, I think?);
