java - How to pass the dynamic added values into servlet -


i want value

name="product' + counter + '"

its dynamic values when click add crate row, can 1 tell me how dynamic values , how should pass servlet , how can in servlet. using form submission : jsp , java env.

$("#addrow").on("click", function () {         counter++;          var newrow = $("<tr>");         var cols = "";         cols += '<td><input type="text" name="product' + counter + '"/></td>';         cols += '<td><input type="text" name="price' + counter + '"/></td>';         cols += '<td><input type="text" name="qty' + counter + '"/></td>';         cols += '<td><input type="text" name="linetotal' + counter + '" readonly="readonly"/></td>';         cols += '<td><a class="deleterow"> x </a></td>';         newrow.append(cols);         alert(cols);         $("table.order-list").append(newrow);     });

no need add counter, change code this.

$("#addrow").on("click", function () {         counter++;          var newrow = $("<tr>");         var cols = "";         cols += '<td><input type="text" name="product"/></td>';         cols += '<td><input type="text" name="price"/></td>';         cols += '<td><input type="text" name="qty"/></td>';         cols += '<td><input type="text" name="linetotal" readonly="readonly"/></td>';         cols += '<td><a class="deleterow"> x </a></td>';         newrow.append(cols);         alert(cols);         $("table.order-list").append(newrow);     });

and in servlet array of values linked each input box below code.

string[] products = request.getparametervalues("product"); string[] prices= request.getparametervalues("price"); string[] qtys= request.getparametervalues("qty"); string[] linetotals = request.getparametervalues("linetotal");

edit added complete code
