First, let's introduce event bubbling and event capture. The processing mechanism for events in the browser defaults to event bubbling, for example #div1 { width:500px;height:500px; Background:rgb (12,42,31); } #div2 { width:450px;height:450px; Background:rgb (212,142,1); } #div3 { width:350px;height:350px; Background:rgb (1,242,153); } Bind Click event: Div1.onclick=function () { alert ("Div1") } div2.onclick=function () { alert ("Div2"
