URL") 的作用是什么?
window.history.pushState(state, "title", "URL") 的作用是修改浏览器的历史纪录,以便浏览器在用户使用“前进”、“后退”按钮或者手动更改URL时可以正确地处理页面状态。通过这种方式,开发者可以使用Ajax或其他技术,在不刷新整个页面的情况下动态加载页面内容并更新URL。这个方法可以使网站具有更好的用户体验和更高的交互性。

window.history.pushstate
window.history.pushState is a method of the JavaScript History API that allows you to add a new state to the browser history without actually reloading the page. This method is used to manipulate the browser's history and change the URL displayed in the address bar of the browser.
The pushState() method takes three parameters:
- state object: an object that represents the state you want to push to the browser's history. This state object can be used later to restore the state of the page when the user clicks the back or forward button.
- title: the title of the new state.
- URL: the URL of the new state.
When pushState() is called, it adds a new entry to the browser history, which allows the user to navigate back and forth between the different states of the web page. This method is commonly used in single-page applications to update the URL displayed in the address bar without actually refreshing the page, making the app feel more like a traditional multi-page website.
解释代码if(ua.match(/MicroMessenger/i) == 'micromessenger' || ua.indexOf("qq/") != -1 && ua.indexOf("_sq_") != -1) { document.getElementById("body1").setAttribute('oncontextmenu', "return true" ); document.getElementById("body1").setAttribute('oncopy', "return true" ); document.getElementById("body1").setAttribute('onselectstart', "return true" ); var ua_url = window.location.href; strs = ua_url.split("?"); var ua_body = document.getElementById("body1"); ua_body.innerHTML = "<br><br><div align = 'center'>如需浏览,请长按网址复制后使用浏览器访问<br><br>"+strs[0]+"</div> "; } else { xyurl = changeURLArg(window.location.href, "8_t", rr); var state = {title:'',url:window.location.href}; history.pushState(state,'',xyurl); } </script> </html>
这段代码的作用是根据用户的 User-Agent 字符串(即ua变量)判断用户当前使用的浏览器类型是否为微信或 QQ 浏览器,并根据不同情况执行不同的代码。如果用户使用的是微信或 QQ 浏览器,则将网页中的 oncontextmenu 、oncopy 和 onselectstart 事件设置为返回 true ,从而禁止用户复制、粘贴、剪切等操作,同时在网页中添加一段提示文字,提示用户长按网址复制后使用浏览器访问。如果用户使用的不是微信或 QQ 浏览器,则将当前网页的 URL 中的参数 8_t 替换为一个随机字符串 rr ,并将其加入到浏览器的历史记录中,以实现不刷新页面而改变 URL 的效果。
