I have this JQuery here that I wrote a while ago. I use regex to extrack the price of the service. But now I added free services over a dollar amount, so I have instances in which service names now have 2 currency amounts.
So for example:
Free Shipping US48 $750.00 -- $0.00 USD
I just want the last match. Currently I get 2 matches,
$750.00
$0.00
Not sure if I should try and rewrite the Regex, or rewrite the JQuery.
I'm terrible with Regex, that's why I'm asking.
var rate_API_Text = $('input[name*="_lb_OP_AO_S2_Quotes_Original_Field"]:checked').next().text();
var rate_API_Index = rate_API_Text.indexOf("--");
var rate_API_Name = rate_API_Text.substr(0, rate_API_Index - 1);
$('[id*="_lbl_OP_AO_S2_Dashboard_StatusMessage_Field"]').text(rate_API_Name);
var rate_Amount = "$0.00";
var re_ratePlan = new RegExp("(\\$[0-9,]+(\\.[0-9]{2})?)");
var txt_ratePlan = $('input[name*="_lb_OP_AO_S2_Quotes_Original_Field"]:checked').next().text();
var match_ratePlan = re_ratePlan.exec(txt_ratePlan);
if (match_ratePlan.length !== null || match_ratePlan.length > 0) {
for (var i = 0; i < match_ratePlan.length; i++) {
rate_Amount = match_ratePlan[i] + "\n";
break;
}
if (match_ratePlan !== null) {
$('[id*="_lbl_OP_AO_S2_Dashboard_Calc_RateAmount_Field"]').text(rate_Amount);
}
else {
$('[id*="_lbl_OP_AO_S2_Dashboard_Calc_RateAmount_Field"]').text("$0.00");
$('[id*="_txt_Estimated_Rate_Field"]').val(rate_Amount);
}
}

I changed the source of the regex to the latter part of the string index instead.
That's what happens when you have to go back to code you wrote years ago. You forget exactly how it operates and you have to rethink it again.
var rate_API_Text = $('input[name*="_lb_OP_AO_S2_Quotes_Original_Field"]:checked').next().text();
var n = rate_API_Text.indexOf("--");
var rate_API_Name = rate_API_Text.substr(0, n - 1);
$('[id*="_lbl_OP_AO_S2_Dashboard_StatusMessage_Field"]').text(rate_API_Name);
var rate_Amount = rate_API_Text.substr(n, rate_API_Text.length - 1);
var re_ratePlan = new RegExp("(\\$[0-9,]+(\\.[0-9]{2})?)");
var match_ratePlan = re_ratePlan.exec(rate_Amount);
if (match_ratePlan.length !== null || match_ratePlan.length > 0) {
for (var i = 0; i < match_ratePlan.length; i++) {
rate_Amount = match_ratePlan[i] + "\n";
break;
}
if (match_ratePlan !== null) {
$('[id*="_lbl_OP_AO_S2_Dashboard_Calc_RateAmount_Field"]').text(rate_Amount);
}
else {
$('[id*="_lbl_OP_AO_S2_Dashboard_Calc_RateAmount_Field"]').text("$0.00");
$('[id*="_txt_Estimated_Rate_Field"]').val(rate_Amount);
}
}

Rather than re-inventing the wheel, have you considered using one of the many existing libraries that provide this type of functionality?
For example:

<java>
I am trying to store user input (string values) into a 2d array but am unable to figure out how to do a for loop for String values.
User will input a First Name, Last Name, Phone, and Age
public class Lab2
{
public static void main(String[] args) {
//Example Data but need it entered by a user
String [][] array = {
{"Ryan", "Smith", "555555555", "12"},
{"George", "Young", "123456789", "52"},
{"Frank", "McDonnell", "555123789", "18"}
};
//Create a for loop for user input
//Displays the entire array
for (int row=0; row<array.length; row++){
="" for="" (int="" col="0;" <array[row].length;="" col++){
="" system.out.print(array[row][col]+"="" ");
="" }
="" system.out.println();
}
}
}

You could possibly fetch the RSS feeds from different news websites, like BBC etc. They all provide you with functionality to fetch the latest feeds from their servers and you can then render those RSS feeds on your website.
The website would then act as an RSS feed reader. Before you begin, I would recommend that you read about RSS[^], RSS feeds (same as RSS) and RSS Readers (the application which pulls the RSS feeds and then display them in the device). Understand them and them implement the service in your application.
Also, why would you like to pull it using JavaScript when you can pull it using your server-side language too? Which would be much more fast and efficient.

I want to load a png image in base64 to html5 canvas element. I have this code:
<html>
<head></head>
<body>
<canvas id="pageCanvas"></canvas>
<script type="text/javascript">
var canvas = document.getElementById("pageCanvas");
var ctx = canvas.getContext("2d");
var imageData ="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";
var imageObj = new Image();
imageObj.src = imageData;
ctx.drawImage(imageObj, 50, 100);
</script>
</body>
</html>
The above code working well in IE, chrome, Microsoft edge. But in Firefox the image was not displayed. It display blank page. Sometime when we reload the page then it displayed an image in canvas.
Best,

There is no such code that works "sometimes". Code either works or doesn't work, but it can depend on the underlying libraries and stuff like that so the first time it doesn't work because the framework isn't ready and then works because everything is set up.
But it is still not convincing to believe that a reload fixes everything. Take this, press F12 and try to look for the error that this image gives. Console would log the error and you can see that error to find a solution, or post it here so we may help you.

I'm doing an assignment with an order form and was wondering if there is a function that will auto fill the cost field after entering the quantity field?
|
|
|
|

You really miss the point of having an assignment: you are supposed to figure it out, and in the process, learn!
You may wish to get used to that idea sooner, rather than later, as that's what this business is all about.
Here's something for you to consider that's an important part of figuring out how to answer your question: where is the cost-per-unit data located at the time the quantity is entered? A lot depends upon that.

Yeah - I noticed that when I tried to see what else he's been up to (i.e., aside from trying to get his homework done). I think what was most annoying is that I even gave him some suggestions rather than the tried-and-true "Do Your Own Homework".
Maybe someone can develop a CP-AI that would recognize the new accounts created by those who are thrown out of the hamster cage.

Lots of homework[^] it seems.

No. You have to write it yourself.
There are only 10 types of people in the world, those who understand binary and those who don't.

I still can believe the web runs on it! If there is any proof the devil exists javascript must be it.
It is so easy to make a mistake and not catch it until you are debugging.

I can understand your frustration. Maybe you want to take a look on TypeScript.
|
|
|
|
|
I've done some typescript and I absolutely love what Anders Hedjelsberg did.
The library I will be using still needs a typescript facade though , so I have to stick with javascript.
I can't help but wonder what were the twisted minds that created this devil-spawn language thinking when they were going through the design process.

I do believe they were thinking about making a language the ENTIRE web could run on. Not simply making the process easy or simple for you.
