特殊。' > < 输入 类型 = text id = txtQty'。

RSD_No。 ' value = '。

Quantity。' readonly >
< 输入 类型 = text id = txtUP name = txtUP。

here is my php code to display the values.

<input type="text" id="txtParticulars" name="txtParticulars" value="'.$Particular.'"><input type="text" id="txtQty'.$RSD_No.'" value ="'.$Quantity.'" readonly>
<input type="text" id="txtUP" name="txtUP'.$RSD_No.'" /><input type="text" id="txtTotal'.$RSD_No.'" readonly>
Total:<input type="text" id="txtGrandTotal" class="add" readonly />

and the javascript.

function calc(row)
{
    var in1=document.getElementById('txtQty'+row).value;
    var in2=document.getElementById('txtUP'+row).value;
    var in3=in1*in2;
	var total = document.getElementById('txtTotal'+row).value=in3.toFixed(2); 
}

I have textboxes that has a value, what I need is to get the grand total.

Particular.'"><input type="text" id="txtQty'.

RSD_No.'" value ="'.

Quantity.'" readonly> <input type="text" id="txtUP" name="txtUP'.
