edit1= 清除示例代码 edit2= 好尴尬，现在我将发布实际代码

我正在尝试制作自定义的内部街景。我试图通过用变量替换下面函数的参数来将自定义内部镜头转换为相对于任意起始位置，但会破坏街景。我不熟悉javascript。

description:"TEST TEST TEST TSET",latLng:new google.maps.LatLng(54.156654,69.696969)

运行良好。

var demolat = 34.995348; // declared at beginning of function
var demolon = 135.7395;
var wlat = demolat;
var wlon = demolon;

.. lots of code .. // lots of code goes here

description:"TEST TEST TEST TSET",latLng:new google.maps.LatLng(wlat,wlon)

不起作用。

完整代码

替换上述行时，脚本将无法正常工作。
