AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];

var page = PDFViewerApplication.pdfViewer.getPageView(pageIndex);
var pageRect = page.canvas.getClientRects()[0];
var selectionRects = window.getSelection().getRangeAt(0).getClientRects();
var viewport = page.viewport;
var selected = selectionRects.map(function (r) {
  return viewport.convertToPdfPoint(r.left - pageRect.x, r.top - pageRect.y).concat(
     viewport.convertToPdfPoint(r.right - pageRect.x, r.bottom - pageRect.y)); 
});

# how to run this thingy
# create a file on your mac called setup.sh
# run it from terminal with: sh setup.sh

# heavily inspired by https://twitter.com/damcclean

Whenever the server returns validation errors and we would set them with setFieldError they would be lost if any field would get a change or blur event. But we want to keep these kind of errors until the specific field changes. Additional we want to handle generic server errors (which are not specific to a field, but the whole form).

With these hooks field specific server side errors should be added like this:

const { setStatus } = useFormikContext();

const errors = {};
// adjust serverErrors to your own responses
// in this case they look like this: Array<{ name: string, error: string }>
