/*此处省略若干行代码*/ let UserArray = []; /*此处省略若干行代码*/ Page({ data: { /*此处省略若干行代码*/   userarray: UserArray, }, /*此处省略若干行代码*/ Func:function(){ /*此处省略若干行代码*/ userinfotmp = {   nickname: res.content,   hour: options.value1,   minute: options.value2,   second: options.value3,   userid: id }; /*此处省略若干行代码*/ this.setData({  userarray: this.data.userarray.push(userinfotmp) }); /*此处省略若干行代码*/ } /*此处省略若干行代码*/ }) 请问this.setData中怎样用push给数组赋值？上述代码中 userarray: this.data.userarray.push(userinfotmp) 的写法是否正确？如果错误，应该怎么写？

  onLoad: function (options) {     let tmp = '1';     let modal = wx.showModal({// 模态对话框       title: '留下大名！',       showCancel: false,       editable: true,       placeholderText: '请留下你的大名：',       success: function (res) {           if (res.confirm) {             // res.content获取用户输入信息             console.log('用户点击确定', res.content);             tmp = res.content;           }       }     });     this.setData({       nickname: tmp,       hour: options.value1,       minute: options.value2,       second: options.value3,     });   }, 如上所示，怎样把wx.showModal中的success()的参数res的属性content 的值导出来？用过return res.content，失败了；用这个tmp = res.content又失败了。请教懂这个的大侠，谢谢！
