Validate Jeditable field

Question

I'm using Jeditable (posting to CakePHP) for input on my page. I want users to only fill in numbers in the Jeditable fields, so my idea was to also use the jQuery validation plugin to validate if only numbers are used, I already use this in other parts of my site.

Jeditable dynamically creates a form with an input when you click on the div, so there seems to be nothing for Jquery validate to bind to and it doesn't seem to work as normal.

I'm able to set the class name of the form through Jeditable (it only has a class atrribute), the created input only has a name attribute which defaults to "name".

My questions:

• Is this a good way to require only numbers?
• If so, how to make it work with Jquery validate
• If not, what would be a better solution?

Thanks in advance, and I look forward to any answers I might get ;)

Answer 1

You can use the onsubmit event in Jeditable and check if the input has only numbers. This is just an example, I didn't try it:

function isNumeric(value) {
  if (value == null || !value.toString().match(/^[-]?\d*\.?\d*$/)) return false;
  return true;
}

$('.edit').editable(your_url, {
    onsubmit: function(settings, original) {
        if (isNumeric(original)) {
            return true;
        } else {
            //display your message
            return false;
        }
    }
});

Hi, this code worked for me

function isNumeric(value) {
  if (value == null || !value.toString().match(/^[-]?\d*\.?\d*$/)) return false;
  return true;
}

$('.edit').editable(your_url, {
    onsubmit: function(settings, td) {
      var input = $(td).find('input');
        var original = input.val();
        if (isNumeric(original)) {
            console.log("Validation correct");
            return true;
        } else {
            console.log("Validation failed. Ignoring");
            input.css('background-color','#c00').css('color','#fff');
            return false;
        }
    }
});
