This should be pretty simple. I'm trying to use the slice method to remove the last two characters in a dynamically created string in a shopping cart.

So instead of having a product show as $28.00, I want the product to show up as $28. Since these values are coming from a database, I can't simply define the string in a variable, like I've seen in a lot of tutorials.

I've created a JSFiddle here: /

The jQuery that's not working is below:

    $(".myclass").slice(0,-2);

• 1 Don't you have to remove the last three to go from "$28.00" to "$28"? – Mike Samuel Commented Mar 27, 2013 at 23:29

You should use text.

$(".slice").text(function(i, text) {
    return text.slice(0, -2);
});

• i Reffers the index position of the element in the set
• text Reffers the old text value

Very Simple. I uses this for getting number from a string you can use it too.

var height= "800px";

var newheight = height.substring(0,height.length-2); //string 800
newheight= parseFloat(newheight) || 0; //number 800
