To get No.of Excel sheet records in textbox using javascript
Jul 15 2019 1:19 AM
I want to get excel file starting data and ending data on textboxes named "start_row" and "end_row"
to fetch all the records excel data I used javascript function given below :
function Upload() {
//Reference the FileUpload element.
var fileUpload = document.getElementById("ExcelFile");
//Validate whether File is valid Excel file.
var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.xls|.xlsx)$/;
if (regex.test(fileUpload.value.toLowerCase())) {
if (typeof (FileReader) != "undefined") {
var reader = new FileReader();
debugger
//For Browsers other than IE.
if (reader.readAsBinaryString) {
reader.onload = function (e) {
FillRow(e.target.result);
};
reader.readAsBinaryString(fileUpload.files[0]);
} else {
//For IE Browser.
reader.onload = function (e) {
var data = "";
var bytes = new Uint8Array(e.target.result);
for (var i = 0; i < bytes.byteLength; i++) {
data += String.fromCharCode(bytes[i]);
}
};
reader.readAsArrayBuffer(fileUpload.files[0]);
}
} else {
alert("This browser does not support HTML5.");
}
} else {
alert("Please upload a valid Excel file.");
}
};
function FillRow(data) {
debugger
var workbook = XLSX.read(data, {
type: 'binary'
});
var sel_val = document.getElementById("ddlSheetName").value;
var txt_start_row = document.getElementById("start_row");
var txt_end_row = document.getElementById("end_row");
