如何在上传文件夹时限制文件名中的特殊字符 [英] How I do restrict special characters in file name while uploading a folder

问题描述

获取文件夹名称我正在使用此功能



函数selectFolder（e）{

var theFiles = e.target。文件;

var relativePath = theFiles [0] .webkitRelativePath;



var folder = relativePath.split（/）;

alert（文件夹[0]）;

To get a folder name i am using this function

function selectFolder(e) {
var theFiles = e.target.files;
var relativePath = theFiles[0].webkitRelativePath;

var folder = relativePath.split("/");
alert(folder[0]);

var match = (new RegExp('[~#%\&_{}+\|]|\\.\\.|^\\.|\\.$')).test(folder);

               if (match) {
                   alert("File Name should not contain specail charcters");
                   document.getElementById('Upload1').value = "";
               }
               else {

               }

}



当我上传带有文件的文件名时，我遇到了问题，它正在考虑将其视为特殊字符..





请帮忙..？



我在哪里修改.. ??

试试

try

var specialChars = "#%&*:<>?/{|}";
for (var i = 0; i < files.length; i++) {
    var file = files[i];
    var name = file.name;
    for (j = 0; j < specialChars.length; j++) {
        if (name.indexOf(specialChars[j]) > -1) {
            alert("Special Characters [ # % & * : < > ? / { | } ] are not allowed in the file name \n\n\n" + name);
            e.preventDefault();
            break;
            return;
        }

    }
