Due to security mechanism issues, the value of input[type="file"] cannot be modified using js, so it cannot be reset like other form elements. After consulting the information, use the following method to reset:

function resetInputFile(inputfile){
    if(inputfile[0].value){        
    try{
            inputfile[0].value="";
        }catch(error){
        }        
        if(inputfile[0].value){            
        var form = document.createElement('form');            
        var existingItem= inputfile.nextSibling;            
        var parent = inputfile.parentNode;  
            form.appendChild(inputfile);  
            form.reset();  
            parent.insertBefore(inputfile,existingItem);  
        }  
    }
}
Copy after login

It has been verified that it cannot be used under IE. The reason is: IE does not allow moving elements in different documents, so form.appendChild(inputfile ); An error will be reported here that the program cannot be executed
