Why does Javascript eliminate leading zeros in strings?

When utilizing ui-router to retrieve parameter values from a URL using $stateParam, one of the parameters is an ID number that may or may not start with 00. For example, 0034323343. Throughout the entire application, the leading zeros remain intact. However, there seems to be an issue when adding state to an object like this:

SharedDataService.setBreadcrumb({
                state: 'notes({ claimID: ' + $stateParams.claimID + ', cardholderId: ' + $stateParams.cardholderId + ' })',
                name: 'Notes'
            });

For some reason, the leading zero gets stripped off. The ID ends up being 34323343 in the URL. Despite confirming that

typeof($stateParams.cardholderId)
returns string, the zero goes missing. Why could this be happening?

Below is the object that gets saved:

Object {state: "notes({ claimID: 187337, cardholderId: 0034323343 })", name: "Notes"}

I printed this object to console upon setting this value. Notice how the state shows the cardholderId in the correct format - with leading zeros. Yet, why does it change to an integer when displayed inside a div using {{ crumb.state }}?

Answer №1

Remember to wrap the variables in " to ensure they remain as strings within the stringified object.

'createEntry({ userID: "' + $stateParams.userID + '", accountID: "' + $stateParams.accountID + '" })'
