Every IF statement is not executing in my React code

Question

I am writing a form validation script in React but inside a function I have put multiple if statement. All the if/else statement supposed to be executed but only the final if statement is executing. What am I doing wrong? please help. I provided the code below.

const onSubmitHandle = () => {

    if (name.length===0) {
        setErr ({ ...err,
            nameText:'Please enter name'
        })
    } else {
        setErr ({ ...err,
            nameText:''
        })
    };

    if (number.length<=5) {
        setErr ({ ...err,
            numberText:'Please enter a valid number'
        })
    } else {
        setErr ({ ...err,
            numberText:''
        })
    };

    if (email.length===0) {
        setErr ({ ...err,
            emailText:'Please enter email'
        })
    } else {
        setErr ({ ...err,
            emailText:''
        })
    };

    if(err.emailText.length===0 && err.nameText.length===0 && err.serviceText.length===0 && err.budgetText.length===0 && err.numberText.length===0) {
        alert('Your request is succesfully submited. We will reach you soon')
        setName('');
        setService('');
        setBudget('');
        setNumber('');
        setEmail('');
    };
}

Please help

Answer 1

So it seems you are spreading the err variable wrong, i think what you want is:

setErr ({ 
   err:{
     ...err,
     emailText:'yadayadayada'
   }
})

by doing this you create a new var err with the old properties and still add a new one that you want (read up on spread operator) and you were right in this example it is not needed the return since you want to run all verifications
