在网页中使用客户端脚本(无服务器代码),如 javascript,如何导入、编辑和替换 txt 文件中的文本?我只是尝试使用两个变量(名称和 IP 地址)并将它们替换为文本文件。现有的文本文件很长,我想自动化这个过程。如果脚本在每次提交时也自动创建一个新的文本文件,那就太好了。谢谢!
这是我的代码:
<html>
<head>
<title>TExt File Changer v1</title>
<script type="text/javascript">
function findaNamendReplaceAll() {
var findaName = "Site_Name";
var findaCIP = "192.168.0.5";
var replaceaName = document.myInput.replaceWithName.value;
var replaceaCIP = document.myInput.replaceWithCIP.value;
var fulltexta = document.myInput.fulltext.value;
/*
var nr = new RegExp(findaName,"ig");
var tmp = fulltexta.replace(/Site_Name/gi, replaceaName).replace(/192.168.0.5 /gi,replaceaCIP);
document.myInput.fulltext.value = tmp;
*/
document.myInput.fulltext.value = fulltexta.replace(/Site_Name/gi, replaceaName).replace(/192.168.0.5/gi,replaceaCIP);
}
var str += ‘SECTION ethernet’/n;
str += ‘ETHERNET=UP’/n;
str += ‘BOOTP=server’/n;
str += ‘HOSTNAME=Site_Name’/n;
str += ‘IPADDR=192.168.0.4’/n;
str += ‘NETMASK=255.255.255.0’/n;
str += ‘DNS=‘/n;
str += ‘DHCP_RANGE_L=192.168.0.20’/n;
str += ‘DHCP_RANGE_U=192.168.0.100’/n;
str += ‘SEARCH=‘/n;
str += ‘ZEROCONF=YES’/n;
str += ‘ETH0_ADD_DEFAULT=on’/n;
str += ‘ENDSECTION ethernet’/n;
str += ‘‘;
</script>
