将以下代码 script $#parenid lieachfunction i b $#parenid li eqi childrendiv eq1 csswidth calc100 - $bchildren0clientWidthpx; ; script改为原生写法

var parent = document.getElementById("parenid"); var lis = parent.getElementsByTagName("li"); for (var i = 0; i < lis.length; i++) { var divs = lis[i].getElementsByTagName("div"); var b = lis[i]; divs[1].style.width = "calc(100% - " + b.children[0].clientWidth + "px)"; }
