JQuery Removing the last two characters in a class

Question

It should be pretty simple. I am trying to use the slice method to delete the last two characters in a dynamically created line in a shopping cart.

So, instead of showing the product as $ 28.00, I want the product to show as $ 28. Since these values ​​come from the database, I cannot just define a string in a variable, as I saw in many tutorials.

I created a JSFiddle here: http://jsfiddle.net/EbckS/

JQuery, which does not work, is below:

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

Answer 1

You must use text .

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

• i Returns the index position of the item in the set.
• text Returns the old text value

Answer 2

Very simple. I use this to get a number from a string, which you can also use.

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