FR10可以用这个方法没有错,但是在FR11里面,lab块设置背景图片,要这样
setTimeout(function() {
$(".report-main-parameter-container-controller-label.bi-basic-button.cursor-pointer.cursor-default.bi-f-c.bi-f-h.v-middle.h-center.f-scroll-x").css({'background': 'url(/webroot/help/picture/0002.png)no-repeat','background-size':'100% 100%'});
},100)
