else {
showalert("No Record Available For This Quote");

as you are saying it is working in the Localhost but not in the production server, most likely it seems to me as an URL/Path
issue. 正如您所说的,它在Localhost中运行,但不在生产服务器中运行,在我看来,这很可能是
URL/Path
问题。
1. after observing your code, you are creating one more string Url
variable without using the existing String formFile
variable. 1.观察代码后,您
formFile
创建一个字符串Url
变量,而无需使用现有的String formFile
变量。
as you should provide the valid path
you need to use the formFile
instead of Url
as you have created formFile
using Server.MapPath()
因为您应该提供
valid path
,所以需要使用formFile
而不是Url
因为您已经使用Server.MapPath()
创建了formFile
Try This: 尝试这个:
/*string Url = "../" + file + ".pdf";*/ //comment or remove
String js = @"WindowPopup('" + formFile + "');";//use formFile instead of Url
