我想在代码中提供文件路径，而用户必须上传文件

Question

我选择了上传文件路径代码，并尝试使其自动执行，这意味着我想在代码中提供文件路径，而不是用户必须上传文件

function Summit() {

        var FilePath = "Summer.csv";
        var fileUpload = document.getElementById("fileUpload").value;

        var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.csv|.txt)$/;
        if (regex.test(FilePath.value.toLowerCase())) {
            if (typeof (FileReader) != "undefined") {
                var reader = new FileReader();
                    var table = document.createElement("table");
                    var rows = e.target.result.split("\n");
                    for (var i = 0; i < rows.length; i++) {
                        var cells = rows[i].split(",");
                        if (cells.length > 1) {
                            var row = table.insertRow(-1);
                            for (var j = 0; j < cells.length; j++) {
                                var cell = row.insertCell(-1);
                                cell.innerHTML = cells[j];
                            }
                        }

                    var dvCSV = document.getElementById("dvCSV");
                    dvCSV.innerHTML = "";
                    dvCSV.appendChild(table);
                }
                reader.readAsText(fileUpload.files[0]);
            } else {
                alert("This browser does not support HTML5.");
            }
        } else {
            alert("Please upload a valid CSV file.");
        }
    }
