无法连接到公共Tableau

Question

自昨天上午以来间歇性连接Public Tableau。

其他论坛建议对IE9进行更改，即

var shifting = false; var ctrling = false; var mousing = false; var mouseenter = 0; var mouseleave = 0; var trajectory = null; $('.myTableBeh tr') .off('click') .off('contextmenu') .on('click', function() { if(!ctrling) { $('.myTableBeh tr, .myTableBeh tr td').removeClass('selected'); $(this).addClass('selected'); $(this).find('td').addClass('selected'); } else if(ctrling && $(this).hasClass('selected')) { $(this).removeClass('selected'); $(this).find('td').removeClass('selected'); } else if(ctrling && !$(this).hasClass('selected')) { $(this).addClass('selected'); $(this).find('td').addClass('selected'); } }) .on('contextmenu', function(ev) { ev.preventDefault(); $('.myTableBeh tr, .myTableBeh tr td').removeClass('selected'); $(this).addClass('selected'); $(this).find('td').addClass('selected'); showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY); return false; }) .off('mousedown') .on('mousedown', function(e) { mousing = true; multiselectrow($(this)); }) .off('mouseenter') .on('mouseenter', function(e) { mouseenter = e.clientY; multiselectrow($(this)); }) .off('mouseleave') .on('mouseleave', function(e) { mouseleave = e.clientY; if(shifting && mousing) { tmptrajectory = mouseenter - mouseleave < 0?1:-1; } if($(this).hasClass('selected') && shifting && mousing && trajectory != null && trajectory != tmptrajectory) { $(this).removeClass('selected'); $(this).find('td').removeClass('selected'); } if(shifting && mousing && trajectory == null) { trajectory = tmptrajectory; } }) .off('mouseup') .on('mouseup', function(e) { mousing = false; trajectory = null; multiselectrow($(this)); });

我重启机器，问题仍然存在。如何排除故障？
