针对如图效果:如何优化以下代码?使得A列(空白列)及最后列(空白列)不选择到?,也就是指定B-X列生效,其他列不生效? var background_color = "rgb(209,228,255)"; //新背景色 var frozen_back_color = new Array(); var back_color = new Array(); var $last_tr; var i = 0; // 2行除外 $('.x-table tr:gt(2) ').bind("mouseenter", function() { //$(".x-table tr") if (typeof($last_tr) != "undefined") { if (typeof($(this).attr("id")) != "undefined") { if (typeof($("#content-container #frozen-west").attr("id")) != "undefined") { $("#content-container #" + $last_tr.attr("id")).each(function() { $(this).children("td").each(function() { $(this).css("background-color", frozen_back_color[$(this).index()]); }); i = i + 1; }); i = 0; } else { $last_tr.children("td").each(function() { $(this).css("background-color", back_color[$(this).index()]); }); } frozen_back_color = []; back_color = []; } } if (typeof($(this).attr("id")) != "undefined") { if (typeof($("#content-container #frozen-west").attr("id")) != "undefined") { $("#content-container #" + $(this).attr("id")).each(function() { frozen_back_color = new Array(); $(this).children("td").each(function() { frozen_back_color[$(this).index()] = $(this).css("background-color"); $(this).css("background-color", background_color); }); i = i + 1; }); i = 0; } else { $(this).children("td").each(function() { back_color[$(this).index()] = $(this).css("background-color"); $(this).css("background-color", background_color); }); } } }); //2行除外 $('.x-table tr:gt(2)').bind("mouseleave", function() { if (typeof($(this).attr("id")) != "undefined") { $last_tr = $(this); } }); |
