js替代marquee實(shí)現(xiàn)圖片無(wú)縫滾動(dòng)
可能大家都碰到過(guò)，當(dāng)marquee中滾動(dòng)的是圖片的時(shí)候，滾到終點(diǎn)的時(shí)候直接就跳回到起點(diǎn)了，而不像文字那樣可以無(wú)縫滾動(dòng)，下面介紹的是通過(guò)js來(lái)實(shí)現(xiàn)圖片的無(wú)縫滾動(dòng)。
先了解一下下面這幾個(gè)屬性：
innerHTML: 設(shè)置或獲取位于對(duì)象起始和結(jié)束標(biāo)簽內(nèi)的 HTML
scrollHeight: 獲取對(duì)象的滾動(dòng)高度。
scrollLeft: 設(shè)置或獲取位于對(duì)象左邊界和窗口中目前可見(jiàn)內(nèi)容的最左端之間的距離
scrollTop: 設(shè)置或獲取位于對(duì)象最頂端和窗口中可見(jiàn)內(nèi)容的最頂端之間的距離
scrollWidth: 獲取對(duì)象的滾動(dòng)寬度
offsetHeight: 獲取對(duì)象相對(duì)于版面或由父坐標(biāo) offsetParent 屬性指定的父坐標(biāo)的高度
offsetLeft: 獲取對(duì)象相對(duì)于版面或由 offsetParent 屬性指定的父坐標(biāo)的計(jì)算左側(cè)位置
offsetTop: 獲取對(duì)象相對(duì)于版面或由 offsetTop 屬性指定的父坐標(biāo)的計(jì)算頂端位置
offsetWidth: 獲取對(duì)象相對(duì)于版面或由父坐標(biāo) offsetParent 屬性指定的父坐標(biāo)的寬度
