[英]What is causing the error “Uncaught TypeError: number is not a function”
I have an onchange event that updates a form, and in the updating process it calls a function to calculate shipping. 我有一个更新表单的onchange事件,并在更新过程中调用一个函数来计算运费。 I'm not sure why, but I'm getting the following error when I try to call the function: 我不确定为什么,但是当我尝试调用该函数时,我收到以下错误:
Uncaught TypeError: number is not a function
The function, shipping
, looks like this: 功能, shipping
,看起来像这样:
function shipping( weight )
{
var flat
switch( weight )
{
case 1:
case 2:
case 3:
flat = 32.00;
break;
case 4:
flat = 18.50;
break;
case 5:
flat = 15.80;
break;
case 6:
flat = 14.00;
break;
case 7:
flat = 12.71;
break;
case 8:
flat = 11.75;
break;
case 9:
flat = 11.00;
break;
case 10:
flat = 10.40;
break;
case 11:
flat = 9.91;
break;
case 12:
flat = 9.50;
break;
case 13:
flat = 9.15;
break;
case 14:
flat = 8.86;
break;
case 15:
flat = 8.86;
break;
case 16:
flat = 8.38;
break;
case 17:
flat = 8.18;
break;
case 18:
flat = 8.00;
break;
case 19:
flat = 7.84;
break;
case 20:
flat = 7.70;
break;
} // switch
var flat_fee = flat * weight;
var mile_fee = distance * 0.90;
var shipping_fee = flat_fee + mile_fee;
simpleCart.shippingTest = shipping_fee;
return shipping_fee;
} // shipping
I'm passing in 1
right now. 我现在正在传球1
。 The variable distance
is coming from an ajax call that is completed before this function is run. 可变distance
来自在运行此函数之前完成的ajax调用。 That function looks like this: 该函数如下所示:
function get_distance( zip )
{
$.getJSON(
'distance.php',
{ zip:zip },
function(json)
{
distance = json
})
} // get_distance
I've checked to make sure the variable distance
is set. 我已经检查过以确保设置了可变distance
。
The console says the uncaught type error is happing at the line where I call shipping(1)
. 控制台说未被捕获的类型错误正在我称之为shipping(1)
的线路上shipping(1)
。 Any thoughts as to why that's happening? 有关为什么会发生这种情况的任何想法?
Are you using shipping
as a variable anywhere? 您是否在任何地方使用shipping
作为变量? Sounds like the function
shipping is getting overwritten by using it as a variable
with a numeric value of 1
. 听起来像使用数字值为1
的variable
来覆盖function
运输。
It's not in the code you posted (neither is the call to shipping(1)
you mentioned). 它不在您发布的代码中(也不是您提到的shipping(1)
号码shipping(1)
)。
