Definition and usage

The ng-paste directives are used to tell AngularJS what to do when text is pasted on an HTML element.

The ng-paste instruction does not override the element's native onpaste event, and when the event is triggered, both the ng-paste expression and the native onpaste event are executed.

Grammar

< element ng-paste="expression" > < /element >

< input > , < select > , < textarea > And other editable elements support this directive.

Parameter value

expression	文本粘贴到元素上执行的表达式。
