I am searching for a method to turn a numeric value such as $10.00 into a symbol.
I need to have symbols to represent the price of a product.
A good example is:
http://www.customink.com/categories/short-sleeve-t-shirts/16/styles#facets/
Instead of displaying prices they show currency symbols. So the price of a cheap item is represented by $ while a more expensive item is $$$
For the code it needs to:
For a value between $1-$10.99 to display it as $
For a value between $11-$25.99 to display it as $$
For a value between $26-$200 to display it as $$$
Thank you, for any guidance you can provide.
What have you tried?
var symbol;
if( value < 11.0 ) {
symbol = "$";
}
else if( value < 26.0 ) {
symbol = "$$";
}
else {
symbol = "$$$";
}
return symbol
Or am I missing something here? There are plenty of more sophisticated approaches, but if those are actually your requirements what is wrong with an if/else clause?

var orangeCost = function (pricePerOrange, amountOfOranges) {
var totalCost = pricePerOrange * amountOfOranges;
console.log(totalCost + " Dollar total cost");
};
orangeCost(5, 5);
25 Dollar total cost
NaN Dollar total cost
Why does it also log the "NaN" part instead of only the 25 Dollar stuff ?
thank you
The only way a multiplication could result in NaN is if the variables were undefined, meaning you're calling the function without passing pricePerOrange or amountOfOranges, or if one of the variables is a string.
Make sure you're passing variables to orangeCost, and that those variables are in fact Numbers.

Trying to add a second condition to a js function
original condition
if (content.length==elmnt.maxLength)
new condition
if (content.length==elmnt.maxLength && current form field value > 1400)
how do I code "current form field value > 1400" properly in javascript?
Full original code:
<SCRIPT TYPE="text/javascript">
function jumpField(elmnt,content)
{
if (content.length==elmnt.maxLength)
{
next=elmnt.tabIndex
if (next<document.forms[0].elements.length)
{
document.forms[0].elements[next].focus()
}
}
}
</SCRIPT>
Thanks!
Not sure if I fully understand what you are trying to achieve.
Are you looking for parseInt() to convert a string value? Like:
parseInt(document.forms[0].elements[next].value) > 1400

I have an object in Angular looking like this:
$scope.addEmployeeDepartments={ 5066549580791808=true, 6192449487634432=true, 7192449487634432=false}
How do I generate a comma-separated string like this
var ids="5066549580791808, 6192449487634432"
containing all the keys which are true ?
Btw, I am using underscore.js in other parts of my solution, so I don't know if that makes it easier.
thanks
Thomas
You can do this with reduce in one pass:
var collect_trues_in = function(a, v, k) {
if(v)
a.push(k);
return a;
};
var csv = _($scope.addEmployeeDepartments).reduce(collect_trues_in, [ ]).join(', ');

i want to decode the string such us: \u003cPoint x\u003d\"214\"
What is the best javascript library for this purpose?
You can use this
var x = "\u003cPoint x\u003d\"214\"";
var r = /\\u([\d\w]{4})/gi;
x = x.replace(r, function (match, grp) {
return String.fromCharCode(parseInt(grp, 16)); } );
x = unescape(x);
console.log(x);

Say I have a range which consists of < -10 and I split this up using a regex call which leaves me with < -10.
I then have a function which gets me the number from the split and I call it like range1.getMin(), this would return -10 but when I use range1.getMin().indexOf('-') it doesn't work.
Try comparing to zero:
var isNegative = range1.getMin() < 0;
function isMin(value) {
if(value<0) {
return true;
}
return false;
}
You could add a check like eval() for the value to make sure you're dealing with an integer.
Also, if you need to make sure you have a positive number (or negative number for that matter) before you use the number in your process, you can Math.abs() your number to make sure it's always a positive number.
var val = parseInt("-10", 10)
can be used to parse integer and to test for positive number
val >= 0
