locally, the uploaded image is converted to Base64 code and saved to an array, and the same file cannot be added continuously. At this time, if you add another picture, you will have no problem if you add it back to the previous one.

    <input  type="file" name="file" class="jokeFile" value="" id="addUppLoadFile" onChange="addUploadInvoice()" accept="image/*">
     

window.addUploadInvoice = ()=>{
    let ffval = $("-sharpaddUppLoadFile").val();
    if(!/.(jpg|jpeg|png|bmp)$/.test(ffval)){
        commonModule.showAlertTips("jpgjpegbmppng")
        return false;
    }

    let addfile = document.getElementById("addUppLoadFile").files[0];
    let rWind = new FileReader();  //
    rWind.onload = function(){
        addModalVm.localImgList.push(rWind.result);
        console.log(addModalVm.localImgList.length)
    }
    rWind.readAsDataURL(addfile);
}
