如何防止用户按后退键移动页面。 [英] How to prevent user to move back page on pressing of back space key.
问题描述
阻止用户通过java脚本按下后退空格键移回页面。
我可以尝试这个但它不应该在Firefox浏览器上工作但是工作在Google Crome浏览器上。
我可以使用此代码。
< script language =javascripttype =text / javascript >
函数cancelBack（）
{
if（（event.keyCode == 8 || （event.keyCode == 37&& event.altKey）||（event.keyCode == 39&& event.altKey））
&&
（event.srcElement.form == null || event.srcElement.isTextEdit == false））{
event.cancelBubble = true;
event.returnValue = false;
}
}
< / script>
并像这样调用这个函数。
< body onkeydown =return cancelBac k（）;>
< / body>
请任何人帮我解决这个问题。
提前谢谢。

推荐答案
你可以使用这个剧本
You Can Use This Script
<script type ="text/javascript">
window.onload = window.history.forward(0); //calling function on window onload
</script>
您不应该这样做。覆盖用户期望的行为不是良好的用户体验。如果必须，请尝试使用event.preventDefault（）;
您可以返回false作为附加措施。下面的代码支持IE< 9.这假设你在if子句中的所有条件都是正确的，我只是复制它们。
You shouldn't do it. Overriding the behaviour the user expects is not good user experience. if you have to, try using event.preventDefault();
You could return false as additional measure. The code below supports IE < 9. This assumes all your conditions in if clause are correct, I just copied them.
var event = e || window.event;
if ((event.keyCode == 8 || (event.keyCode == 37 && event.altKey) || (event.keyCode == 39 && event.altKey))
&&
(event.srcElement.form == null || event.srcElement.isTextEdit == false)) {
event.stopPropagation ? event.stopPropagation() : (event.cancelBubble=true);
}
如果这有帮助请花时间接受解决方案。谢谢。
