Number with leading zeroes gets changed in JavaScript

Question

I am calling a javascript function from php using a print statement to print out html code, and I am passing in an integer. However, the value when it is passed in php is not matching the number that the javascript function receives, and I have no clue why. Here is the php that calls the javascript function: ``` $upc = $items[$i]->GetUPC(); print "upc: " . $upc . "
"; $delete = "

"; ``` The print statement prints out the value: 0011110416605 And on the page, using view source, here is the tag for this: ``` ``` Here is the javascript function that is being called: ``` function removeFromCart(itemID){ var option = document.getElementById("select_cart"); var selected = option.options[option.selectedIndex].value; alert(itemID); loadCart(itemID,selected,"","remove"); } ``` The alert box is printing out the number: 1226972549 I could un…

Accepted Answer

JavaScript thinks it is an octal value (because of the leading zero and the lack of digits greater than `7`). The decimal value of octal `0011110416605` is `1226972549`. Example:

```
> var value = 010; //10 in octal
> console.log(value);
> 8  //is 8 in decimal
```

Use a string instead:

```
removeFromCart("0011110416605")
```
