最下面加这个试试
$("#rightlayoutShow .mini").click()或者修改顶部的html
var returnHtml = "<span class='mini' style=\"cursor:pointerdisplay:none\"></span><span class='zoom' style=\"cursor:pointerdisplay:block\"><img src=\"diaocha/\vote/\guanggao.gif\"></span>"returnHtml += "<div id='iframesrc' style=\"display:none\"></div>"
