将多行插入数据库

Question

我有多行插入，所以，我想将它们插入数据库。 我正在尝试使用循环函数将它们发送到表中;但没有成功。请有人帮忙吗？

//Adding New Line Item Function
	var i = 1;
	function AddNew(){
		if (i <=3){ //if you don't want limit, you remove IF condition
				i++;
				var div= document.createElement('div');
				div.innerHTML = '<input type="text" value="'+i+'" name="lineitem_'+i+'" maxlength="2" size="2"> <input type="text" name="materialcode_'+i+'" placeholder="Material Code" maxlength="18" size="18"> <input type="text" name="qty_'+i+'" placeholder="Quantity" maxlength="10" size="10"> <input type="text" name="price_'+i+'" placeholder="Price" maxlength="10" size="10"> <input type="button" onclick="removeItem(this)" value="-">';
				document.getElementById('addingitem').appendChild(div);
		}
	}
	
	function removeItem(div){
		//document.getElementById('addingitem').removeChild(div.parentNode);
		i--;
		var addingitem = document.getElementById('addingitem');
		addingitem.removeChild(div.parentNode);
		var inputs = addingitem.querySelectorAll('[name^="lineitem_"]');
		for (var r = 0; r < inputs.length; r++) 
		{
			var item = inputs[r];
			item.value = r + 1;
		}
  		inputs = null;
	}
	//Validate Number Key
	function isNumberKey(evt){
    var charCode = (evt.which) ? evt.which : evt.keyCode
    return !(charCode > 31 && (charCode < 48 || charCode > 57));
	}
