首先你要把按钮计算出来
原文链接：https://www.f2er.com/php/131926.html那么onclick的calculateprice你必须调用函数chkprice()
function chkpice()
{
var a=document.getElementById("options_1_text").value;
var b=document.getElementById("options_2_text").value;
var c=document.getElementById("options_3_text").value;
var d=document.getElementById("options_4_text").value;
var e=<?PHP echo $_product = $this->getProduct()->getPrice()?>;
var f=(a+b+c+d)+e;
var e=document.getElementById(('product-price-'+<?PHP echo $_product = $this->getProduct()->getId()?>)).innerHTML;
$('product-price-'+<?PHP echo $_product = $this->getProduct()->getId()?>).innerHTML =''+e.replace(<?PHP echo $_product = $this->getProduct()->getPrice()?>,d)+'</span>';
}
设置了options_1_text,options_2_text,options_3_text,options_4_text把你的id将会得到你的结果
