gender: {
defaultValue: '',
rules: [
{
pattern: function (value) {
return !!value;
},
error: '请选择性别'
}
]
}
这边 return !!value,两个感叹号的用法看不懂 求解
line30: userList: this.state.bookList.filter(item => item.id !== user.id)
should be userList: this.state.userList.filter(item => item.id !== user.id)
handleValueChange (field, value, type = 'string') {
// 由于表单的值都是字符串,我们可以根据传入type为number来手动转换value的类型为number类型
if (type === 'number') {
value = +value;
}
this.setState({
[field]: value
});
}
这里不是很懂,如何转换number类型的,还有field是啥呢
应该是roadhog版本升级导致的吧,解决步骤如下:
1.因为public下文件默认会被拷贝至dist目录, 所以将index.html从public中移出放在src下, 后缀改为ejs.
2.roadhog 2.0的配置文件从 .roadhogrc 更名为 .webpackrc, 所以将其更名为.webpackrc, 在其中增加配置 html: { template: './src/index.ejs' },
3.roadhog build即可.
