Ensure the robustness of the program var leader = parseInt (getStyle (tag, attr)) | | 0 / / part of the retardation formula is to change the value of step var step = (target-leader) / 10; / / the value will be rounded by offsetLeft. If step is relatively small, it will cause problems that cannot be moved / / change the rounding method step = step > 0 according to the positive or negative number of steps? Math.ceil (step): Math.floor (step); / / ease formula leader = leader + step; / / set to an attribute tag.style [attr] = leader + "px" / / check whether you have reached the specified position if (leader = = target) {clearInterval (tag.timer);}}, 17) } / / used to get a style attribute value of a tag / / function getStyle (tag, attr) {/ / detect which / / box.currentStyle is supported, if there is no value of undefined / / getComputedStyle if the browser does not support it.
