1、div元素的执行顺序：
mouseover--> mousedown-->mouseup-->click -->mouseout
2、input、checkbox 、select 元素执行顺序：
mouseover--> mousedown-->focus-->mouseup-->click -->mouseout-->blur
3、先点击input再点击div时，整个执行顺序是：
input----mousedown-->
input----focus-->
input----mouseup-->
input----click-->
div---mousedown-->
input----blur-->
div---mouseup-->
div---click
