我遇到的问题
当我调整网格大小时，分页工作正常如果我不更改CSS
如果我更改CSS FROM .ui-jqgrid .ui-jqgrid-bdiv {overflow: auto;} TO .ui-jqgrid .ui-jqgrid-bdiv {overflow: inherit !important;}，分页栏会在记录之间流动
我更改CSS的原因是我点击“点击我”时会显示一个叠加层链接在每行的第二列。更改CSS会正确显示页面上最后一条记录的叠加层。如果我不更改CSS，则会隐藏页面上最后一条记录的叠加层。
因此，
我不会更改CSS
我更改了CSS
我尝试使用CSS定位和z-index进行叠加，但它不起作用。
答案 0 :(得分：1)
如果我理解正确，您需要执行以下操作
onCellSelect: function (rowid, iCol, cellcontent, e) {
$("#myoverlay").remove();
if (this.p.colModel[iCol].name === 'Overlay') { // iCol === 1
$('<div class="overlay" id="myoverlay">This is an overlay.</div>').css({
top: e.pageY,
left: e.pageX
}).appendTo('body');
}
}
而不是loadComplete中的代码。重要的是，上面的代码会将div附加到<body>而不是<td>元素。可以使用点击的event将div放在相应的位置。
请参阅演示here。
您可以轻松修改代码以使用div的内容，具体取决于rowid，cellcontent或任何其他条件。
<!DOCTYPE html ...之前使用<html>，并在type="text/css"中使用<style>属性。 jqGrid没有cache: true选项。
