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);

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?

Can someone please tell me how to compare elements in array with every other element. I mean in array arr = [a,b,c,d];, I would like to compare a with b,c,d , b with a,c,d, etc. And to do that dynamically, no mather of the size of the array.
Try this:
var a=["a","b","c","d"];
for(var i=0;i<a.length;i++){
for(var j=0;j<a.length;j++){
if(i!=j && a[j]===a[i]){
//match, do whatever you want
}
}
}

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(', ');

that's part of my script:
var count = $(".sliderItem").length;
if (count < lp + 5)
{
alert("bp4");
var clips = count-l;
alert("bp5");
}
so the problem is: 'bp4' is visible but 'bp5' not.
when I change var clips = count-1; to var clips = 1; it works fine.
Somebody have some idea?
You don't have var clips = count-1; in your code, you have var clips = count-l;.
Change the letter l (lower case L) to 1 in your code.
