推荐答案

问题尚不清楚.如果我正确理解了您的问题，则无法阻止页面刷新.它是浏览器的功能，您无法通过页面中的代码对其进行控制.

Question is not clear. If I understand your question correctly, you cannot prevent a page refresh. It is a functionality of the browser and you cannot control it through code in your page.

刷新"页面时，总是会发生页面加载.这就是刷新"的本质.除此之外，您的问题无法准确回答，因为这里没有人理解.

When you "refresh" a page, a page-load is always going to happen. That''s the nature of a "refresh". Beyond that, your question is impossible to answer with any accuracy because nobody here understands it.

1.当用户使用Java脚本(使用F5按钮的键代码)按下F5时，可以避免刷新页面.

1. you can avoid refreshing page when user press the F5 using Java Script(Using Key Code of the F5 button).

document.attachEvent("onkeydown", my_onkeydown_handler);
function my_onkeydown_handler() {
    switch (event.keyCode) {
        case 116 : // ''F5''
            event.returnValue = false;
            event.keyCode = 0;
            window.status = "We have disabled F5";
            break;
    }
}

2.当用户单击鼠标右键并通过Java脚本选择重新加载"选项时，可以避免刷新页面(我们可以在JS中找到鼠标按钮)

2. you can avoid refreshing page when user click the right mouse button and selects the Reload option by Java script(We can find the mouse button in JS)Restrict RIGHT CLICK.
3. To avoid the browser refresh(Need to open the page in pop-up).

These are not solutions. better tell me reason to avoid refresh. may You have a design flaw with your page.
