GetOrderList(tabIndex,1,function () {

var containerHight = parseFloat($("#wrapper").height()) ;
if (activeHight <= containerHight)
activeHight = containerHight;
$(".swiper-container").height(activeHight);
});哪裡錯了什麼 報錯 callback is not a function

理解與使用Javascript中的回呼函數
如 @sunshine999 所說，把callback()在外面定义，再将其作为参数传递给GetOrderList。
function callback() {
var activeHight = $(".swiper-slide").eq(swiper.activeIndex).height();
var containerHight = parseFloat($("#wrapper").height()) ;
if (activeHight <= containerHight)
activeHight = containerHight;
$(".swiper-container").height(activeHight);
}
GetOrderList(tabIndex,1,callback); 在執行之前確保回調函數是一個函數
在呼叫之前檢查作為參數被傳遞的回調函數確實是一個函數，這樣的做法是明智的。同時，這也是實現條件回呼函數的最佳時間。
function GetOrderList(tabIndex,dirc,callback){
...
//确保callback是一个函数
if(typeof callback === "function"){
//调用它，既然我们已经确定了它是可调用的
callback(options);
}
}我這回答最上面貼的那篇文章講的很詳細了。

試下`
callback = function（）{
var activeHight = $(".swiper-slide").eq(swiper.activeIndex).height();
var containerHight = parseFloat($("#wrapper")
var containerHight = parseFloat($("#wrapper"). height()) ;
