未捕获的TypeError: Cannot read property '零
Uncaught TypeError: Cannot read property 'paypal_form' of null
所以我在我的网站上得到以下错误:
Uncaught TypeError: Cannot read property 'paypal_form' of null
下面是问题部分:
success:function(data){
if(typeof(data.paypal_form)!=null)
{
谁能告诉我如何修复这个输入错误? 试试这个
success:function(data){
if(!data)
{
console.log("data is null");
return;
}
if(!data.paypal_form)
{
console.log("data.paypal_form is null");
return;
}
if(typeof(data.paypal_form)!=null)
{
