numberTextBox

A numeric input.

Basic input

Enter a number and leave the field. The datastore receives a number.

lbl is optional: omit it for an input without a visible label. These examples use the default label placement; no lbl_position is required.

Python

Python recipe

from gramlot.page import WebPage


class Page(WebPage):
    """A numeric input."""

    def main(self, root):
        pane = root.div(datapath="field")
        pane.data(".value", 12)
        pane.numberTextBox(
            value='^.value',
            lbl='numberTextBox',
            width='100%'
        )
        pane.p("Stored value:")
        pane.pre("^.value")

JavaScript

export function build(root) {
  const pane = root.div({datapath: "field"});
  pane.data(".value", 12);
  pane.numberTextBox({

    lbl: "numberTextBox",
    width: "100%"
  });
  pane.p("Stored value:");
  pane.pre("^.value");
}

This first example covers basic input and data binding. Additional options and edge cases will be added progressively.
