JSLint Validation error “combine this with the previous var statement”

Question

JSLint Validation error \"combine this with the previous var statement\"

How do I combine this so I don\'t get JSLint Validation error? I get the validation error on

Answer 1

This error means that you have multiple var statements in some of your functions, such as:

var x = 1;
var y = 2;

JSLint wants you to combine the variable declarations in a single var statement like:

var x = 1,
    y = 2;

Answer 2

I think JSLint is referring to these few lines of your code (towards the bottom of the code you have provided):

var userEnteredDate = new Date($('#dateOfLastAccident').val()); // variable that stores user entered date
var today = new Date(); 
var minutes = 1000 * 60; // calculation used to convert miliseconds to minutes
var hours = minutes * 60; // calculation used to conver minutes into hours
var days = hours * 24; // calculation used to convert hours to days
var years = days * 365; // calculation used to convert days into years
var daysSinceAccident = Math.floor((today.getTime() - userEnteredDate.getTime()) / days); // calculation used to find the difference between current date and user entered date as a whole number
var className = getClassName(daysSinceAccident); // variable clasName finds the correct css style to apply based on daysSinceAccident

You can avoid declaring them multiple times by delimiting each variable with a comma:

var userEnteredDate = new Date($('#dateOfLastAccident').val()),
    today = new Date(),
    minutes = 1000 * 60,
    hours = minutes * 60,
    days = hours * 24,
    years = days * 36,
    daysSinceAccident = Math.floor((today.getTime() - userEnteredDate.getTime()) / days),
    className = getClassName(daysSinceAccident);
