}

field.status = 1;

var rtn = admin.syncReq(ctx+"/order/orders/modify",field);

console.log("field",field);

if(rtn && rtn.code==0){

layer.msg('操作成功');

active.reload();

form.render();

btn.removeClass("layui-btn-disabled");

layer.close(index);

}else{

layer.msg('操作失败');

btn.removeClass("layui-btn-disabled");

}

});

submit.trigger('click');

}

});

关键代码：一开始直接添加禁用样式

var btn = $("a.layui-layer-btn0");

if(btn.hasClass("layui-btn-disabled")){

return;

}

btn.addClass("layui-btn-disabled");

操作完后，恢复：

btn.removeClass("layui-btn-disabled");
