我使用的是在线模板，我删除了各种内容以进行自己的修改。 有两页， 索引页面将搜索查询作为输入字段，结果页面显示此查询的结果。 Everythying工作正常，但由于我做了修改，结果页面的标题为
＆＃34; undefined - 搜索结果＆＃34;
这个undefined应该显示索引页面的输入字符串。 但我希望它的标题应该只是＆＃34;搜索结果＆＃34;
我能做什么，以便它覆盖这个标题，并且只有我需要的标题。
我试过了
document.title = "This is the new page title.";
在html头下，你可以在脚本中看到。
但是这样做之后显示＆＃34; undefined - 这是新的页面标题。作为标题。
我想删除那个未定义的内容。
这是结果页面的HTML代码，如果你能找到制作标题的最新信息。

答案 0 :(得分：2)
在页面底部试试
$( document ).ready(function() {
document.title = "This is the new page title."
});
答案 1 :(得分：1)
你应该使用。
document.title = "This is the new page title."
但这不符合SEO。
答案 2 :(得分：0)
试试这个：
$('title').html($('title').html().replace("undefined -",""));
使用javascript：
document.title = document.title.replace("undefined -","")
您还需要确保将代码包装在DOM中：
$(document).ready(function(){
$('title').html($('title').html().replace("undefined -",""));//or document.title = document.title.replace("undefined -","")
})
答案 3 :(得分：0)
请试试这个
document.title = "Title here"
