Listen to the carriage return event and pass the parameter on the input element in a non-binding mode, and bind the input

The scenario is to dynamically generate html elements and add events for the generated input.

There are two requirements: The method is not bound and parameters need to be passed; the parameter is the method name, the method is called back and the input value is used as the parameter.

The implementation is as follows:

Input statement

Tmp. push ('<input type = "text" id = "myInput" onkeydown = "if (event. keyCode = 13) {_ callBack ('+ userFunction +')} "> ');

UserFunction indicates the name of the method to be called (method name string)

Javascript writing

Function _ callBack (fuc) {var myInput = document. getElementById ("myInput "). value; if (myInput = null | myInput <= 0) myInput = 1; var func = eval (fuc); new func (myInput );}
