First look at the effect, in the drag Input[range], the following animation will change with the drag, the use of the principle is ngmodel implementation of the communication. The principle of implementation is to implement the communication between the instruction and the outside by introducing ^ngmodel in the instruction.
Here are a few points:
1, $formatters push into the function to achieve modelvalue into Valeuvalue.
2, $render method to render the value of Viewvalue into the template.
3, $setViewValue implement is to update the Viewvalue value in the template.
4, $parsers push in the way to achieve valuevalue into Modelvalue.
