I'm new at this. The input is showing in the text box but not making the calculation for the if statement.
$w.onReady(function () {
$w("#generatequote").onClick((event) => {
var SR = Number($w("#SR").value);
if (SR<100) {
$w("#quotetext").value = SR * 2;
}
//first try- does not calculate
$w("#quotetext").value = fin + "\n" + (name + "\n" + email + "\n" + phonenumber + "\n" + address + "\n"
+ ($w("#quotetext").value = SR))
//Second Try- does not calculate
$w("#quotetext").value = fin + "\n" + (name + "\n" + email + "\n" + phonenumber + "\n" + address + "\n"
+ ($w("#SR").value = SR))
I have also tried replacing "#quotetext" in the if statement with "#SR" but it displays nothing
This is the code displaying the additional else statements
var SR = Number($w("#SR").value);
if (SR<100) {
$w("#quotetext").value = SR * 2;
}
else if (SR>=100&&SR<300) {
$w("#quotetext").value = SR * 1.5;
}
else if (SR>=300&&SR<600) {
$w("#quotetext").value * 1.25;
}
else if(SR>=600) {
$w("#SR").value = ("SR");
}
$w("#quotetext").value = fin + "\n" + (name + "\n" + email + "\n" + phonenumber + "\n" + address + "\n" + ($w("#SR").value = SR))
You are reassigning your $w("#quotetext").value after the if statement ends. Either put the next code in else blocks or the previous outputs won't be shown as they will get replaced by later ones.
Just don't reassign the $w("#quotetext").value after your if statements end, or use a variable in your if statements instead of using $w("#quotetext").value
var SR = Number($w("#SR").value);
if (SR<100) {
SR = SR * 2;
}
else if (SR>=100&&SR<300) {
SR = SR * 1.5;
}
else if (SR>=300&&SR<600) {
SR= SR * 1.25;
}
else if(SR>=600) {
SR = ("SR");
}
$w("#quotetext").value = fin + "\n" + (name + "\n" + email + "\n" + phonenumber + "\n" + address + "\n" + (SR))

I'm using railway API in my website and want the Train data in grid format. Please help me with the same.
I want all the variables (Train name, Train number, Departure Time, Arrival Time, Travel Time, Availability Status) in a table format. I'm calling two APIs to get the final result. How can I achieve this using AngularJs?
function between(trainData) {
var total = trainData.TotalTrains;
for (i = 0; i < total; i++) {
var source = trainData.Trains[i].Source;
var destination = trainData.Trains[i].Destination;
var name = trainData.Trains[i].TrainName;
var number = trainData.Trains[i].TrainNo;
var ttime = trainData.Trains[i].TravelTime;
var deptime = trainData.Trains[i].DepartureTime;
var arrtime = trainData.Trains[i].ArrivalTime;
$('.' + className + '').append("<br/>" + name + "(" + number + ")" + " " + ttime + " " + deptime + " " + arrtime + "<br/>");
}
}
}
you can append with the in the end like
$('.' + className + '').append("<table><tr><th>name</th><th>number </th><th>ttime </th><th>deptime </th><th>arrtime </th><th>classcode </th><th>status </th><th>jdate </th></tr><tr><td>" + name + "</td><td>" + number + "</td><td>" + ttime + "</td><td>" + deptime + " </td><td>" + arrtime + " </td><td>" + classcode + "</td><td>" + status + "</td><td>" + jdate + "</td></tr></table>");
So I have this command that's supposed to display a player's stats if it's found and says player not found otherwise. After I search a player and go to the previous screen, I get "player not found". I thought it was because my loop continues running after the player is found and my boolean becomes false, so I added a break statement. Won't work
function Search(Table, Stat1, Stat2, Stat3, Stat4, Stat5) {
onEvent("Search2.btn", "click", function() {
readRecords(Table, {}, function(records) {
var SearchPlayer = getText("text_input1");
var found = false;
for (var i = 0; i < records.length; i++) {
if ((records[i]).Player == SearchPlayer) {
setScreen("DisplaySearch");
setText("label3", records[i].Player + " Stats" + "\n" + records[i][Stat1] + " " + Stat1 + "\n" + records[i][Stat2] + " " + Stat2 + "\n" + records[i][Stat3] + " " + Stat3 + "\n" + records[i][Stat4] + " " + Stat4 + "\n" + records[i][Stat5] + " " + Stat5 + "\n");
setText("text_input1", "");
setText("label5", "");
found = true;
break;
} else if ((found == false)) {
setText("label5", "Player Not Found");
}
}
});
});
I would need to keep the value from the loop where authorId = 1 and then print it out as another value in the next loop (authorId = 3). I mean that I need to keep authorSurname.value (id = 1) and print it in the loop (authorId = 3) as the secondAuthor.value because in the loop (authorId = 3) the string authorSurname takes another value. Can you tell me how can I fix it?
if(authorId === 0) {
div.innerHTML = firstAuthorSurname.value + year.value + page.value + pageOtherValue;
}
else if (authorId === 1) {
div.innerHTML = firstAuthorSurname.value + " i " + authorSurname.value + " (" + year.value + ");
var secondAuthorSurname = authorSurname.value;
}
else if (authorId === 2) {
return secondAuthorSurname;
div.innerHTML = firstAuthorSurname.value + ", " + secondAuthorSurname.value + " and " + authorSurname.value + " (" + year.value + ") " + firstAuthorSurname.value + ", " + secondAuthorSurname.value + " and " + authorSurname.value + ", " + year.value + ")" + firstAuthorSurname.value + ", " + secondAuthorSurname.value + " and " + authorSurname.value + ", " + year.value + ") showed that... ";
}
Your code does not contain a loop but if you would like to save a value to use outside of a for loop declare the variable outside the loop and then you will have access to it outside the loop.
text = "";
cars = ["honda", "chevy"];
for (i = 0; i < cars.length; i++) {
text += cars[i];
}
console.log(text);
>>hondachevy
If you are trying to save a value to be used in a different condition in the if statement inside a for loop you can follow the same pattern
text = "";
for (i = 0; i < 4; i++) {
if(i === 0){
text += "to be used when i is 1";
}
else if(i === 1){
console.log(text);
text += " hello";
}
}
console.log(text);
output
>>to be used when i is 1
>>to be used when i is 1 hello
Also why don't you use a switch statement instead of a long if else. See the link below for how to do switch statements in javascript.

I'm a beginner to Javascript and I have a basic question about how to use the prompt method. None of the code seems to process below. Is there some sort of hidden rule about using multiple prompt boxes or does my code just have a syntax error? Any help would be much appreciated. Thanks in advance.
<html>
<head>
<title> Two Numbers </title>
<script type="text/javascript">
var first = prompt("Enter first number:");
var second = prompt("Enter second number:");
var sum = (first-0) + (second-0);
var diff = first - second;
var divide = first/second;
var multi = first*second;
document.write(first + " + " + second " = " + sum + "<br />");
document.write(first + " + " + second " = " + diff + "<br />");
document.write(first + " + " + second " = " + divide + "<br />");
document.write(first + " + " + second " = " + multi + "<br />");
</script>
</head>
<body>
</body>
</html>
You're missing a +.
//change this
console.log(first + " + " + second " = " + sum + "<br />");
// to this
console.log(first + " + " + second + " = " + sum + "<br />");
In the future, please use the console for debugging. There is a great article on everything you can do with the console here > https://developer.chrome.com/devtools/docs/javascript-debugging
Corrected the syntax error and corrected the operators in the write() function:
<html>
<head>
<title> Two Numbers </title>
<script type="text/javascript">
var first = prompt("Enter first number:");
var second = prompt("Enter second number:");
var sum = (first-0) + (second-0);
var diff = first - second;
var divide = first/second;
var multi = first*second;
document.write(first + " + " + second + " = " + sum + "<br />");
document.write(first + " - " + second + " = " + diff + "<br />");
document.write(first + " / " + second + " = " + divide + "<br />");
document.write(first + " * " + second + " = " + multi + "<br />");
</script>
</head>
<body>
</body>
</html>
use the console to check for errors, as said by James G
var isValid = true;
var first = prompt("Enter first number:");
if (!Number(first)) {
alert("Please enter numeric value only.");
isValid = false;
}
if (isValid) {
var second = prompt("Enter second number:");
if (!Number(second)) {
alert("Please enter numeric value only.");
isValid = false;
}
if (isValid) {
var sum = first + second;
var diff = first - second;
var divide = first / second;
var multi = first * second;
console.log(first + " + " + second + " = " + sum);
console.log(first + " - " + second + " = " + diff)
console.log(first + " / " + second + " = " + divide);
console.log(first + " * " + second + " = " + multi);
}
}
I have some divs which are generated by jquery. Inside there is showing up the price, the title and the selected option value.
I've tried a lot of things to hide each div class "result" if no option is select, but with no luck.
Is there a way to hide each div without rewriting the whole code?
JS:
function pcc_calc_forms() {
jQuery(".calcolare").each(function (e) {
var t = jQuery(this).attr("id");
var n = pcc_form_data(t);
jQuery("#" + t + "-mostra").html('<h3 class="pcc-total">Totale : ' + n[0] + "" + "€" + '</h3><div class="content">' + n[1] + '<br /><br /></div>')
})
}
function pcc_form_data(e) {
var t = new Array(0, "");
var n = new Array;
var r = new Array;
$("#" + e + " select").each(function (e) {
var title = $(this).attr("data-title");
var inside = $(this).find("option:selected").attr("data-title");
var i = $(this).find("option:selected").html();
if (inside === undefined) {
inside = " ( " + i + " ) "
} else {
inside = " ( " + inside + " ) "
}
var i = $(this).find("option:selected").attr("data-price");
var s = parseFloat($(this).attr("data-mult"));
if (isNaN(s)) {
s = 1
}
var o = parseFloat($(this).find("option:selected").text());
if (isNaN(o)) {
o = 0
}
if (i !== undefined) {
if (i == "this") {
i = o
} else {
i = parseFloat(i)
}
t[0] = t[0] + parseFloat(i) * s;
if (s == 1) {
t[1] = t[1] + "<div class=\"result\"><b>" + title + "" + inside + "</b> : " + parseFloat(i) + "" + " € " + "</div>"
} else {
t[1] = t[1] + "<div class=\"result\"><b>" + title + "" + inside + "</b> : " + parseFloat(i) + " X " + s + " = " + parseFloat(i) * s + "" + " € " + "</div>"
}
}
});
n = [];
r = [];
return t
}
$(document).ready(function () {
pcc_calc_forms();
$(document).on("change", ".calcolare select", function () {
pcc_calc_forms()
});
});
THIS is the link to the fiddle
Thanks in advance for any hint.
$(document).on("change", ".calcolare select", function () {
var i = $(this).find('option:selected').index();
alert(i);
//if(i>0) ppc_calc_forms();
//else $('.results').hide();
})
This will find the index of the selected option... as you can see, it works, just not with your function...
I would simplify that script as much as possible..
I understand not wanting to rewrite the code substantially at this point. However, for comparison, here is the way I would do it while still holding to your general pattern:
function pcc_calc_forms() {
jQuery(".calcolare").each(function (e) {
var t = jQuery(this).attr("id");
var items = pcc_item_data(t);
var totalPrice = $.makeArray(items).reduce(function(total,item,i,a) {
return total+item.price;
},0);
text = '<h3 class="pcc-total">Totale : ' + totalPrice + "" + "€" + '</h3>';
text += '</h3><div class="content">';
items.each(function(i,item) {
if (item.mult > 1)
text += "<div class=\"result\"><b>" + item.title + " ( " + item.name + " )</b> : " + item.price + " X " + item.mult + " = " + item.price * item.mult + "" + " € " + "</div>";
else
text += "<div class=\"result\"><b>" + item.title + " ( " + item.name + " )</b> : " + item.price + "" + " € " + "</div>";
});
text += '<br /><br /></div>';
jQuery("#" + t + "-mostra").html(text);
});
}
function pcc_item_data(e) {
return $("#" + e + " select").map(function (e) {
if (this.selectedIndex > 0) {
var item = {};
item.title = $(this).attr("data-title");
var inside = $(this).find("option:selected").attr("data-title");
var i = $(this).find("option:selected").html();
item.name = inside ? inside : i;
item.price = parseFloat($(this).find("option:selected").attr("data-price"));
var mult = parseFloat($(this).attr("data-mult"));
item.mult = isNaN(mult) ? 1 : mult;
return item;
}
});
}
$(document).ready(function () {
pcc_calc_forms();
$(document).on("change", ".calcolare select", function () {
pcc_calc_forms();
});
});
What I've done:
Separate data collection (pcc_item_data) from data presentation;
this makes the code more readable and easier to maintain later.
Used map (http://api.jquery.com/jQuery.map/) and reduce (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce) to transform / aggregate arrays; they're concise
and expressive once you're familiar with them.
