nt websAspOpen()
功能:主要是创建asp symbol table和write命令
说明:定义了一个write命令,对应的实现函数为websAspWrite
-----------------------------------------------------------------------------------------------------------------
void websAspClose()
功能:关闭Asp symbol table.
说明:
-----------------------------------------------------------------------------------------------------------------
int websAspRequest(webs_t wp, char_t *lpath)
功能:处理asp请求。就是输出一个asp页面,并且将asp页面中的script解析出来,输出到asp页面中。
说明:
1. 标识,头部信息已经向浏览器输出完成
2. 将asp页面读入到内存buf中;
3. 然后在buf中查找<% language=javascript %>
4. 在查找到<%时,将buf中此位置前的页面输出到浏览器;
5. asp中可能存在<% language=javascript %>,也可能不存在<% language=javascript %>,而是存在<% ……. %>。所以需要区分,是<% language=javascript %>时,不向浏览器输出。
6. 然后调用<% %>中的处理程序,输出数据到浏览器,是有区分的(有无EMF_SCRIPT_EJSCRIPT)
7. 最后输出%>位置后的asp页面数据到浏览器中。
-----------------------------------------------------------------------------------------------------------------
int websAspDefine(char_t *name, int (*fn)(int ejid, webs_t wp, int argc, char_t **argv))
功能:定义一个asp 函数script
说明:就是<% %>中对应的处理函数。
-----------------------------------------------------------------------------------------------------------------
int websAspWrite(int ejid, webs_t wp, int argc, char_t **argv)
功能:write命令的实现函数
说明:<%write()%>
-----------------------------------------------------------------------------------------------------------------
static char_t *strtokcmp(char_t *s1, char_t *s2)
功能:在字符s1中查找s2,掠过s1中的空格。
说明:
-----------------------------------------------------------------------------------------------------------------
static char_t *skipWhite(char_t *s)
功能:跳过空格
说明:
<% language=javascript write("Query String: " + QUERY_STRING) %>
<% write("JavaScript is still the selected language"): %>
Today is <% write("Hello World"); %>
例子:
<% language=javascript %>
ASP / JavaScript Test
Expanded ASP data: <% aspTest("Peter Smith", "
<% var z; \
for (z=0; z<5; z=z+1) \
{ \
if (z<=2) \
write(z+" is less than 3
"); \
else if (z==3) \
write(z+" is equal to 3
"); \
else \
write(z+" is greater than 3
"); \
} \
%>
