js sets the html title title
innerText method
Through console.log(document. getElementsByTagName("title")[0]), and found that the
label can be printed. There are only text nodes in the label, so I guess it can only recognize TextNode, so I used innerText to set the value of title, and it succeeded. <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">document.getElementsByTagName("title")[0].innerText = '需要设置的值';</pre><div class="contentsignin">Copy after login</div></div><p class="jb51code"><strong>document.title method</strong><br/></p><p>After testing, the value of title can also be set through document.title. </p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:js;toolbar:false">console.log(document.title); # 可以获取title的值。
document.title = '需要设置的值'; # 设置title的值。</pre><div class="contentsignin">Copy after login</div></div><p><strong>jQuery method</strong></p><p>jQuery method We change the value of title when the browser gains focus and loses focus.
