页面定时自动刷新禁止右键F12代码

采用javascript实现禁止右键和F12查看源代码，这是为了别人不看你的代码，对于不懂得人哦，如果老手是防不住的！

禁止F12代码：

• <script type="text/javascript">
•  
• document.onkeydown = function () {
• if (window.event && window.event.keyCode == 123) {
• event.keyCode = 0;
• event.returnValue = false;
• return false;
• }
• };
• </script>

禁止右键代码:

• <script language="Javascript">
• document.oncontextmenu=new Function("event.returnValue=false");
• document.onselectstart=new Function("event.returnValue=false");
• </script>

自动刷新代码:

• <script language="JavaScript">
• function re_fresh() {
• window.location.reload();
• }
• setTimeout('re_fresh()',15000); //指定15秒刷新一次
• </script>

方案二

• <script type="text/javascript">
• //屏蔽右键菜单
• document.oncontextmenu = function (event){
• if(window.event){
• event = window.event;
• }try{
• var the = event.srcElement;
• if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
• return false;
• }
• return true;
• }catch (e){
• return false;
• }
• }
• //屏蔽粘贴
• document.onpaste = function (event){
• if(window.event){
• event = window.event;
• }try{
• var the = event.srcElement;
• if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
• return false;
• }
• return true;
• }catch (e){
• return false;
• }
• }
• //屏蔽复制
• document.oncopy = function (event){
• if(window.event){
• event = window.event;
• }try{
• var the = event.srcElement;
• if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
• return false;
• }
• return true;
• }catch (e){
• return false;
• }
• }
• //屏蔽剪切
• document.oncut = function (event){
• if(window.event){
• event = window.event;
• }try{
• var the = event.srcElement;
• if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
• return false;
• }
• return true;
• }catch (e){
• return false;
• }
• }
• //屏蔽选中
• document.onselectstart = function (event){
• if(window.event){
• event = window.event;
• }try{
• var the = event.srcElement;
• if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
• return false;
• }
• return true;
• } catch (e) {
• return false;
• }
• }
• </script>
