如何在每次加载页面时仅重新加载一次 [英] How to reload a page only once everytime it gets loaded

问题描述

我有一个JSP页面，即使删除了其中一个内容，该页面仍显示先前的内容.我正在努力寻找问题，但我需要对此进行快速修复.我在 JavaScript 方面很弱，所以请帮帮我.我需要一个 JavaScript ，它将在每次访问该页面时自动重新加载该页面.重新加载页面确实可以解决问题.

I have a JSP page that is showing previous content even after deleting one of the content. I am working to find the problem but I need a quick fix for this. I'm weak in JavaScript so please help me out. I need a JavaScript that would reload the page automatically every time the page is visited. Reloading the page does solve the problem.

推荐答案

如果只想做一次，我会使用localStorage:

If you want to do it just once, I would use localStorage:

if (localStorage.getItem('loadedOnce') === 'true') {
    // don't reload page, but clear localStorage value so it'll get reloaded next time
    localStorage.removeItem('loadedOnce');
} else {
    // set the flag and reload the page
    localStorage.setItem('loadedOnce', 'true');
    document.location.reload(true);
}

我真的建议您调查一下为什么它会损坏，而不是试图解决问题.

I would really recommend looking into why this is broken, instead of trying to hack around the problem.

注意:

这不适用于较旧的浏览器.有关更多信息，请参见 mdn的兼容性表(IE8确实支持该表).

This doesn't work in older browsers. See mdn's compatability table for more information (IE8 does support it however).
