我正在使用一个在线模板,我在其中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,结果页面显示该查询的结果。一切正常,但由于我所做的修改,结果页面的标题为

“undefined - 搜索结果”

这个未定义的应该显示来自索引页面的输入字符串。但我希望它的标题应该只是“搜索结果”

我可以做些什么来覆盖这个标题并只包含我需要的标题。

我试过了

document.title = "This is the new page title.";

如您在脚本中所见,在 html 标题下。

但这样做之后它显示“未定义 - 这是新的页面标题。作为标题。

我想删除未定义的。

这是结果页面的 HTML 代码,如果您能找出标题的原因的话。

最佳答案

在页面底部试试这个

$( document ).ready(function() {
document.title = "This is the new page title."
});
