Submitting form data

I'm trying to create a bookmarklet in chrome that will modify a form's input data.

One of the fields looks like this:

<input type="text" id="shipping:firstname" name="shipping[firstname]" value="John" title="First Name" maxlength="255" class="input-text required-entry" placeholder="First Name*" onchange="shipping.setSameAsBilling(false)" autocapitalize="off" autocorrect="off" oldautocomplete="remove" autocomplete="off">

Open in new window

Yet when I click my bookmark, it just pops up the new user's name in a blank page...
code is simply:

javascript:  let first = document.getElementById('shipping:firstname');  first.value='John';

Open in new window

What am I doing wrong?

Is there a way to monitor and then kill a server request for an image (preferably in JavaScript) if it is taking too long? The image comes from a 3rd party server so I'd have to kill it on the request side. I'm asking due to us firing 3rd party marketing pixels on our web app. Sometimes they take extreme amounts of time to respond.

Hi,
I have 3 apps that are operating within ms/access (split beck end) and need to (i) integrate them in a single unique app and (ii) migrate to a web-based environment (i.e. accessible through a browser) or client/server with the database on the back-end. I recognise that I really must quit ms/access as its restrictions on the GUI are starting to really show and its cracking all over (e..g. it launches explorer to accede to a dynamic net page to show GIS stuff, but the inverse path (from explorer back to ms/access is, simply, impossible).

The back-end database is open but I am able to use any common databases, ODBC databases as I will limit both the field types and the functions, but I need to process images (I have been doing it with bought controls).

My first idea is to go with NetBeans or IntelliJ or Azure but I am terribly hesitating. If its desktop based, the final app needs to run on many platforms or then be web-based. Running on IOS/Android would also be a requirement.

can anyone help?

(in total I gave roughly 300 forms and 150 reports and about 450 columns... (not counting roughly 200 queries over 150 tables).

Can anyone help to coach me on a convenient path?

all hints will be cheerfully accepted

PS I am able to pay for a licensed platform. My current MS/Access "bloat" came from the extraordinary EE sopport...

I need help writing a Javascript function which will take a string as an arugment and then filter out an array of strings starting with the string I pass as an argument.
So if I have the following array:
let words = ['simple', 'single', 'side', 'sacked', 'apple', 'orange']
I need a javascript funtion that will look at every string in this array, and give me a second array called myFilteredWords which start with the letters 'si" - assumuming that I pass 'si" as an argument to the funtion.

Hello Experts,

This issue is concerning an ASP.NET webpage that's currently used in our contact center.
It's a personalized launch page for users, with links they need to do their jobs.
But recently some of the tools used by our colleagues have changed.

The problem is, some links now work faster in IE and some faster in chrome.
And the difference in speed is rather dramatic in some cases.

I need a way to force the individual links to open in the fastest browser.

Many Thanks!
Maurice

Hello Experts,
I have a Onclick event attached to button which should open a window (on Javascript), which is working just fine. But, when I click on another URL same window opens up, which is not related to the URL at all. Any idea what could be going on? Please try to help. Thank you in advance.

Help building and searching an Array

I am trying to send a text message (SMS) using email by using the telephone number, and the carrier specific suffix. For example, to send to a Boost Mobile customer, you would simply send an email to: 8135551212@myboostmobile.com - and it will send a text message to that number. Each carrier has its own suffix.

I have a list of carrier information:

Carrier            SMS gateway domain
Alltel            [insert 10-digit number]@message.alltel.com
AT&T            [insert 10-digit number]@txt.att.net
Boost Mobile      [insert 10-digit number]@myboostmobile.com
Cricket       [insert 10-digit number]@mms.cricketwireless.net
Project Fi      [insert 10-digit number]@msg.fi.google.com
Sprint            [insert 10-digit number]@messaging.sprintpcs.com
T-Mobile      [insert 10-digit number]@tmomail.net
U.S. Cellular      [insert 10-digit number]@email.uscc.net
Verizon            [insert 10-digit number]@vtext.com
Virgin Mobile      [insert 10-digit number]@vmobl.com
Republic Wireless[insert 10-digital number]@text.republicwireless.com

Our C# driven site already has code set up to send an email. We call the c# controller from Javascript like this:

var objToSend = {
     Email: "john@gmail.com",
     Body: "This is the body of the email",
     Subject: "Hello from our site."
}

// Call controller to send the email
$.post('/Contact/NotifyAdmin', objToSend);

Open in new window

So what I want to do is, re-use our existing code to send a text message.

Assuming I have the carrier and phone number available to me, how would I use our existing code?

var phoneNumber = "8135551200";
var carrier = "Verizon";

// Somehow I need to "build" the phone number in its correct format and pass as the "Email" property

// Then.. call our controller as normal

Open in new window

I think this is an ARRAY problem, isn't it? Can anyone help me get me going?

Thank you for looking.

Regards,

John

Hi: I have a website that I use to store pdf's of safety documents at our company. I have a flash movie (flash5 !) that navigates from the factory to the department to the workcentre to the role ; and from there launch a php/mysql table that lists and accesses the pdf's appropriate to that role. THe problem is navigation; when I am on the 'php' page I have left the flash movie. If a user wants to go back into the navigation they have to restart the flash movie from the beginning, which kind of disrupts navigation.
Soooo my question is - it it possible to launch a flash movie AT A SPECIFIED FRAME? I think the answer lies in javascript of which I know next to nothing......
Thanks!
