我在下面有这个例子，我想为桌子的主体创建一个滚动条。确实它有效，但我在这里使用像素而不是百分比滚动（$（'＃tblNeedsScrolling'），700）; 。并限制绿框内的表格。
你能帮帮我吗？提前致谢。
function scrolify(tblAsJQueryObject, height){
var oTbl = tblAsJQueryObject;
// for very large tables you can remove the four lines below
// and wrap the table with <div> in the mark-up and assign
// height and overflow property
var oTblDiv = $("<div/>");
oTblDiv.css('height', height);
oTblDiv.css('overflow','scroll');
oTbl.wrap(oTblDiv);
// save original width
oTbl.attr("data-item-original-width", oTbl.width());
oTbl.find('thead tr td').each(function(){
$(this).attr("data-item-original-width",$(this).width());
});
oTbl.find('tbody tr:eq(0) td').each(function(){
$(this).attr("data-item-original-width",$(this).width());
});
// clone the original table
var newTbl = oTbl.clone();
// remove table header from original table
oTbl.find('thead tr').remove();
// remove table body from new table
newTbl.find('tbody tr').remove();
oTbl.parent().parent().prepend(newTbl);
newTbl.wrap("<div/>");
// replace ORIGINAL COLUMN width
newTbl.width(newTbl.attr('data-item-original-width'));
newTbl.find('thead tr td').each(function(){
$(this).width($(this).attr("data-item-original-width"));
});
oTbl.width(oTbl.attr('data-item-original-width'));
oTbl.find('tbody tr:eq(0) td').each(function(){
$(this).width($(this).attr("data-item-original-width"));
});
}
$(document).ready(function(){
scrolify($('#tblNeedsScrolling'),700); // 700px is height <-- I would like to change it to percentage
});
$("body").css("overflow", "hidden");<head>
