为什么setData会无效，也不出错

[gzwlj2001]

如题：console.log一直输出undefined，但输出e.detail.value又是对的,刚学小程序开发，想不明白 按网上说的 改成 var that = this 也没用

data: {
items: [
{ name: 'wx-auto', value: '记住密码，下次自动登录' },
],
strKHKey:"",
strwxtel:"",
boolwxtelEnabled:false,
strpw:"",
boolpwEnabled:false,
boolAuto:true
},

KHKeyInput:function(e){
this.setData({
strKHKey:e.detail.value
})
console.log("strKHKey:"+this.strKHKey)
},

data: { items: [ { name: 'wx-auto', value: '记住密码，下次自动登录' }, ], strKHKey:"", strwxtel:"", boolwxtelEnabled:false, strpw:"", boolpwEnabled:false, boolAuto:true }, KHKeyInput:function(e){ var that = this; that.setData({ strKHKey:e.detail.value }) console.log("strKHKey:"+that.strKHKey) },

[木头印象]

console.log("strKHKey:"+that.strKHKey) ; 上面漏了个；号

晕，没仔细看，之所以是undefined，是因为少了个data，应该是： console.log("strKHKey:",this.data.strKHKey)
