有这样一个方法
function Add()
{
var p1=document.getElementById("txtEXO_NUM1");
var p2=document.getElementById("txtFC_FU_NUM1");
var p3 = document.getElementById("lblOUTFIT_VAL1");
if(p1.value==null||p2.value==null)
{
p3.innserHTML="0";
}
else{
p3.innerHTML=((parseInt(p2.value)/parseInt(p1.value))*100).toString();
}
}
我一个table里面有很多textbox
<table>
<Tr>
<Td>txtEXO_NUM1(textbox) onblur="Add();" </td> <td>txtFC_FU_NUM1(textbox) onblur="Add();" </td>
</tr>
<Tr>
<Td>txtEXO_NUM2(textbox) onblur="Add();" </td> <td>txtFC_FU_NUM2(textbox) onblur="Add();" </td>
</tr>
<Tr>
<Td>txtEXO_NUM3(textbox) onblur="Add();" </td> <td>txtFC_FU_NUM3(textbox) onblur="Add();" </td>
</tr>
<Tr>
<Td>txtEXO_NUM
