Question

第1行：

<input id="Text1" type="text" /><input id="Button1" type="button" value="button" />

第2行：

<a target="_blank" href="http://search.twitter.com/search?q=#msdhoni">#msdhoni</a>
<div class="twitStream 5" id="tweets" title="#msdhoni" >

我想要的 - 当用户在文本框中输入一些东西（在第1行）时，在点击按钮（第1行）时应该成为div的标题（第2行）。实际上想要用文本框中的文本输入替换代码中的#msdhoni。

我使用的Jquery代码:(请建议更改此代码以使其成为可能）

String.prototype.linkify=function(){
return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&;\?\/.=]+/g,function(m){
return m.link(m);
});
};
String.prototype.linkuser=function(){
return this.replace(/[@]+[A-Za-z0-9-_]+/g,function(u){
return u.link("http://twitter.com/"+u.replace("@",""));
});
};
String.prototype.linktag=function(){
return this.replace(/[]+[A-Za-z0-9-_]+/,function(t){
return t;
});
};

var showTweetLinks='none';
function fetch_tweets(elem){
elem = $(elem);

keyword = escape(elem.attr('title'));


num=elem.attr('class').split(' ').slice(-1);

Answer 1

这是我从你的问题中理解的：

 $(function () {
            $("#Button1").click(function () {
                $("#tweets").attr("title", $("input[id='Text1']").val());
                $.each($("input:text"), function () {
                    $(this).val($("#tweets").attr("title"));
                });
            });
        });
