What about:

var value = "8.8 mi";
var number = parseFloat(value); // 8.8

Looks like what you are looking for here.

Use regex to remove the text from the end of the string:

var expr = / mi$/;
var value2 = value.replace(expr, "");

And like h2ooooooo commented, you can use a group to match on:

var expr = / (hr|mi|sec)$/;

And for "other white values": `/ (mi|foo|bar)$/`. – h2ooooooo May 01 '14 at 14:08

if it's only mi at the end then it should work

value= 8.8 mi;
trimValue = value.substr(0,value.length-2);
