暂时记录下问题还未解决 input图 input代码
直接用controller的fieldadd时候就可以给最前面一个没有有效输入的input获取焦点
input
key{field.id} // important to include key with fields id
{...field}
/
TextField图 TestField代码
必须用registercontroller的field无效没有add自动获取最前面无效输入的表单
TextField{...field}labelUsernamevariantoutlined{...register(test.${index}.value, {required: {value: true,message: required}})}/
x-data-picker
用controller的fields或者regiter都无效 完整代码
