手机应用,jsp页面input框如何禁止复制粘贴?,第1张

jsp页面input框禁止复制黏贴,主要是通过设置禁止复制黏贴的属性为false来完成,如下代码:

<input type="text" oncopy="document.selection.empty()" onpaste="return false"  value="测试是否可以复制粘贴"/>

第二种方式是设置input的输入框为不可编辑,呈现为灰色。

<!-- 禁止选择文本: -->

<script type="text/javascript">

var omitformtags=["input", "textarea", "select"]

omitformtags=omitformtags.join("|")

function disableselect(e){

if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)

return false

}

function reEnable(){

return true

}

if (typeof document.onselectstart!="undefined")

document.onselectstart=new Function ("return false")

else{

document.onmousedown=disableselect

document.onmouseup=reEnable

}

</script>

<!-- 禁用右键: -->

<script>

function stop(){

return false

}

document.oncontextmenu=stop

</script>

功能:禁止右键、禁选择、禁粘贴、禁shift、禁ctrl、禁alt

<script language="JavaScript">

<!--

function key(){

if(event.shiftKey){

window.close()}

//禁止Shift

if(event.altKey){

window.close()}

//禁止Alt

if(event.ctrlKey){

window.close()}

//禁止Ctrl

return false}

document.onkeydown=key

if (window.Event)

document.captureEvents(Event.MOUSEUP)

function nocontextmenu(){

event.cancelBubble = true

event.returnValue = false

return false}

function norightclick(e){

if (window.Event){

if (e.which == 2 || e.which == 3)

return false}

else

if (event.button == 2 || event.button == 3){

event.cancelBubble = true

event.returnValue = false

return false}

}

//禁右键

document.oncontextmenu = nocontextmenu // for IE5+

document.onmousedown = norightclick // for all others

//-->

</script>

<body onselectstart="return false"onpaste="return false">
