(Js Tips) input text box press ENTER or lose the cursor trigger event

Question 1:
When the input text box is input, press enter, or the cursor is lost, the event is triggered.

Implementation Method
Onchange = "window. alert ('trigger event, handle thing')" // when the cursor is lost, the event is triggered and processed
Onkeypress = "if (event. keyCode = 13) {window. alert ('trigger event, handle thing'); return false;}" // press enter to trigger the event and process it

Note: return false must be added to the onkeypress event. The statement mainly avoids the loss of input items in the input.

Complete example:
<Input type = "text" id = "inputGoodNo" style = "width: 197px; Height: 31px; Font-Size: X-Large" onchange = "... do some thing .... "onkeypress =" if (event. keyCode = 13 ){... do some thing ....; return false;} "/>
