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 no

Answer 1

Solve it by creating a hidden text called it 'tempcart' then assing value to it with HTML or PHP, it will keep the leading zeros intact as a text string. To make sure, convert it to string if you are passing it thru PHP

HTML:

<input type='hidden' id='tempcart' value='0011110416605'>

PHP:

$itemID = '0011110416605';
$itemID = strval( $itemID );
echo "<input type='hidden' id='tempcart' value=$itemID >";

SCRIPT:

function removeFromCart() {
var itemID = document.getElementById('tempcart').value;
alert(itemID);
//do whatever...
}

This is just sample programming, you need to fit it in your program. I guess Javascript can't pass due to convertion to octal value (because of the leading zero and the lack of digits greater than 7) as @Vivid mention before.

Answer 2

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")

Answer 3

I found this issue and I fixed it by using parseInt:

itemID = parseInt('0011110416605',10);

Answer 4

You can just call with including '' quotes

Like onchange="updateLineTotal{$id,'{$po101}')";

Just include it in quotes so it will consider it as string not an integer
