Passing math-like string in Javascript

I am having trouble on passing time interval to javascript. The time interval is formatted using minus sign (Eg. 10-11 means from 10 to 11 AM/PM doesn't matter).

In markup I have something like this.

<? $mytime = '10-11';?>

<a href="" onclick="checkTime($mytime)"></a>

In Javascript I have this 

function checkTime(mytime) {
    console.log(mytime);
}

Console window show -1. i need to have the same string I passed. What should I do.

You are printing your php string directly in the onlick function, this will output something like this: 

 <a href="" onclick="checkTime(10-11)"></a>

You can easily see how this will not work. That's why you need to put the single inverted commas before printing your php var, so that it appears as a string in js: onlick="checkTime('10-11')"

Pass value like this 

<a href="#" onclick="checkTime('$mytime')"></a>

instad of 

<a href="" onclick="checkTime($mytime)"></a>

You are passing 10-11. which without '' javascript consider this as number.

This make 10-11=-1

Something like this 

function v(i){console.log(typeof i);}
v(10-11) // number
v("10-11") // string
