我如何编写代码以访问网站并查找标题标签然后显示该数据?

试试这个:

HTML

<div id="hi"></div>

JS(含JQuery)

$.ajax({
url:'https://crossorigin.me/' +
    'https://myurl.com',
    type:'GET',
    success: function(data){
       var x = "";
       x = data.replace(/[^]*<title>/,"");
       x = x.replace(/<\/title>[^]*/,"")
       $("#hi").html(x);
    }
});
