asp下实现代码的“运行代码”“复制代码”“保存代码”功能源码
来源:asp之家 时间:2011-04-14 10:39:00
Function content_Code(Str)
dim ary_String,i,n,n_pos
ary_String=split(Str,"[ code ]")
n=ubound(ary_String)
If n<1 then
content_Code=Str
Exit function
End If
for i=1 to n
n_pos=inStr(ary_String(i),"[/ code ]")
If n_pos>0 then
ary_String(i)="<br /><textarea class=gocode id=runcode"&i&" name=runcode"&i&">" & server.HTMLEncode(left(ary_String(i),n_pos-1))&"</textarea><br /><input type=button class=input-code value=运行代码 onclick=runCode(runcode"&i&")><input type=button class=input-code value=复制代码 onclick=copycode(runcode"&i&")><input type=button class=input-code value=另存代码 onclick=saveCode(runcode"&i&")><span class=code-tishi>提示:您可以先修改部分代码再运行</span><br />" & _
right(ary_String(i),len(ary_String(i))-n_pos-6)
Else
ary_String(i)="[code]" & ary_String(i)
End if
next
content_Code=join(ary_String,"")
End Function
使用方法也很简单:
发表文章时需用使用“运行代码”功能的,主要前后加上
[ code ][/ code ]
比如:
[复制此代码]CODE:
[ code ]
<script type="text/javascript">
alert("简单吧");
</script>
[/ code ]
需要注意的是,在显示的页面要进入以下javascript:
function runCode(obj) {
var winname = window.open('', "_blank", '');
winname.document.open('text/html', 'replace');
winname.opener = null
winname.document.writeln(obj.value);
winname.document.close();
}
function copycode(obj) {
var rng = document.body.createTextRange();
rng.moveToElementText(obj);
rng.scrollIntoView();
rng.select();
rng.execCommand("Copy");
rng.collapse(false);
}
function saveCode(obj) {
var winname = window.open('', '_blank', 'top=10000');
winname.document.open('text/html', 'replace');
winname.document.write(obj.value);
winname.document.execCommand('saveas','','code.htm');
winname.close();
}
