复制代码 代码如下:

columns:[[
{field:\"activitycontent\",title:\'活动内容\',width:fixWidth(0.18),align:\"center\",halign:\"center\",
formatter:function(value,rec){
if(value.indexOf(\"src\")<0){
if(rec.activitycontent.length>Math.ceil(document.documentElement.clientWidth * 0.18)/11.5)
return rec.activitycontent.substring(0,Math.ceil(document.documentElement.clientWidth * 0.18/11.5))+\'..\';
else
return rec.activitycontent.substring(0,Math.ceil(document.documentElement.clientWidth * 0.18/11.5));
}
}
},
{..}
]]
