    let select = (e) => {  

    }  
    let fail = (e) => {  
        //console.log(e);  
    }  
    let imageFileSuccess = (e) => {  
        console.log(e);  
    }  
    let deleteImage=(e)=>{  
        imageBase64.value=null;  
    }  
    let input=ref("")  
let ip=(e)=>{  
        console.log(e,input.value);
