我对report0报表块写了如下js:setTimeout(function() {var a = 'REPORT0'; var b = a.toUpperCase(); var wid = ($("div").width() - 17) + 'px'; $("div").css('width', wid); var height = ($("div").height() - 16) + 'px'; $("div").css('height', height); }, 100);window.flag1 = true;var self1 = this;setTimeout(function() { $("div").find(".frozen-center").mouseover(function() { window.flag1 = false; }); $("div").find(".frozen-center").mouseleave(function() { window.flag1 = true; }); var old = -1; var interval = setInterval(function() { if (!self1.isVisible()) { return; } if (window.flag1) { currentpos1 = $("div").find(".frozen-center").scrollTop; if (currentpos1 == old && 0 != currentpos1) { $("div").find(".frozen-center").scrollTop = 0; } else { old = currentpos1; $("div").find(".frozen-center").scrollTop = currentpos1 + 1.0; } } }, 100); }, 1000);为什么报表快只顾着自己滚动鼠标移上去没有反应?
