杭州交通信息网公司门卫保安岗位职责:asp过滤函数的用法问题
来源：百度文库 编辑：杭州交通信息网 时间：2024/05/09 07:06:32
下面这段函数具体怎么用？能不能给个例子？
function checkStr(str)
if isnull(str) then
checkStr = ""
exit function
end if
checkStr=replace(str,"'","")
checkStr=replace(str,";","")
checkStr=replace(str,"--","")
checkStr=replace(str,"<","<")
checkStr=replace(str,">",">")
checkStr=replace(str," "," ")
checkStr=replace(str,"javascript","/javascript")
checkStr=replace(str,"cookie","/cookie")
checkStr=replace(str,"document","/document")
end function
function checkStr(str)
if isnull(str) then
checkStr = ""
exit function
end if
checkStr=replace(str,"'","")
checkStr=replace(str,";","")
checkStr=replace(str,"--","")
checkStr=replace(str,"<","<")
checkStr=replace(str,">",">")
checkStr=replace(str," "," ")
checkStr=replace(str,"javascript","/javascript")
checkStr=replace(str,"cookie","/cookie")
checkStr=replace(str,"document","/document")
end function
你直接在ASP里调用就行了
比如你现在有一个名为“w”的变量
w的值是被过滤的语句，你想过滤掉w里的“'”、“<”、“javascript”……（也就是上面那个函数的内容）
那么直接用：
df=checkStr(w)
就行了，这就是调用了这个函数
注：df也是一个变量，他的值就是把w的值去掉上面函数中所过滤的那些字符后 的值了。
比如w的值是“javascript000document”（也就是：w="javascript000document"）
用：df=checkStr(w)
后，df的值就是“/javascript000/document”了。
