jquery validate - replace commas in field before validation occurs

问题

It appears that even with the current validate plugin you can't have a comma in a value if you want to validate using min. I found on github where the patch was submitted several months ago (11 months) to modify the source .js file but it's still not in release.

So instead of modifying my source .js file I'm trying to figure out how to replace the comma prior to validation.

I tried something like this:

$("#amount").blur(function(){
    var val = $(this).val().replace(/\,/g,'');
    $(this).val( val ); 
});
$("#transferForm").validate({
    .......
});

But it runs validate first, fails because of min and then replaces the value. I don't necessarily want it to fail validation and tell the user to remove commas - I just want it to remove the comma before running the min rule.

Don't even let them enter comma's

$("#amount").keyup(function(){
    var val = $(this).val().replace(/\,/g,'');
    $(this).val( val ); 
});

Try this http://jsfiddle.net/MWjZr/

$(function(){
  $("input[id=sometexboxid]").each(function(){
      this.value=this.value.replace(/,/g, "");
  }).on('keyup', function(){
      this.value=this.value.replace(/,/g, "");
  })
});
