The difference between trigger and Triggerhandler in jquery

$ ("Form:input"). blur (function//  }). KeyUp (function() {$ (  this). Triggerhandler ("blur");}). Focus (function() {$ (this). Triggerhandler ("blur");}); $ (". Sub"). Click (function() {$ (": input.required"). Trigger ("blur");});

① uses trigger to trigger the blur event that we bind, and then triggers the browser's default Blur event. In that case. KeyUp occurs when the mouse is removed. Not the effect we want.

②triggerhandler will only trigger the blur we bind, not the default event of the browser, relative to Trigger. The KeyUp and focus events can be executed smoothly.
