展开全部一个数末尾的0是由2和5乘出来的,而1到1000里2多得是,主要看1到1000中有多少个5(5的倍数):有一个因数5的:1000/5=200,比如5、10、15、20、25等等有两个因数5的:1000/25=40,比如25、50、75等等,但因为刚才已经计算过一次,所以只能再加40而不是80有三个因数5的:1000/125=8,比如125、250、375等等,同样,前面已经计算过两次了,这里只能加8而不是24有四个因数5的:1000/625=1,1000内只有625是由4个5乘出来的,因为前面已经用过3次了,这里只能加1最后结果:1到1000的数中含有因数5的个数是200+40+8+1得到249',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign),e.getAttribute("jubao"))},getILeft:function(t,e){return t.left+e.offsetWidth/2-e.tip.offsetWidth/2},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#href\}\}/g,e).replace(/\{\{#jubao\}\}/g,n)}},baobiao:{triangularSign:"data-baobiao",tpl:'{{#baobiao_text}}',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign))},getILeft:function(t,e){return t.left-21},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#baobiao_text\}\}/g,e)}}};function l(t){return this.type=t.type
