Signature Component

Note: the 2 pieces of code you need to customize are in bold below:
  1. Exact name of your Model
  2. Exact name of your custom Signature field

var element = arguments[0],
   $ = skuid.$;
$(".nx-page").one("pageload", function() {
    // init signature canvas
    element.jSignature();
    element.jSignature("reset");
    // Create new signature in text field
    var model = skuid.model.getModel('Contact'),
        row = model.getFirstRow(),
        sigField = 'Signature__c',
        sigData = model.getFieldValue(row,sigField);
    if(sigData !== null ) {     // read back Signature data
        element.jSignature("setData", "data:" + sigData);
    }
})
