搜索带有 jQuery 的项目，按回车键后页面将重定向到所选项目 link

Question

我用jQuery做了一个搜索插件。
当用户在搜索项目后在搜索输入中按 enter 键时，我需要将页面重定向到所选项目 href。

jQuery.expr[':'].contains = function (a, i, m) {
    return jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase()) >= 0;
};


jQuery(function ($) {

    $('input[name="search"]').keyup(function () {

        var searchterm = $(this).val();

        if (searchterm.length > 1) {
            var match = $('.item_name:contains("' + searchterm + '")');
            var nomatch = $('.item_name:not(:contains("' + searchterm + '"))');
            match.addClass('selected');
            nomatch.addClass('uk-hidden');

        } else {
            $('.item_name').removeClass('uk-hidden');
            $('.item_name').removeClass('selected');
        }

    });

    var statematch = $('.item_name:contains("استان")');
    statematch.remove().parent();
});

.uk-hidden{
    display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="uk-search">
    <input class="uk-search-field" type="search" name="search" placeholder="search here">
</div>
<div class="ad-city-list">
    <div class="item_name"><a href="tehran.html">Tehran</a></div>
    <div class="item_name"><a href="istanbul.html">Istanbul</a></div>
    <div class="item_name"><a href="tabriz.html">Tabriz</a></div>
</div>

我该怎么做？

Answer 1

试试这个：

 jQuery.expr[':'].contains = function(a,i,m){
            return jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())>=0;
        };


        jQuery(function($) {

            $('input[name="search"]').keyup(function(){ 

                var searchterm = $(this).val();

                if(searchterm.length >1) {
                    var match = $('.item_name:contains("' + searchterm + '")');
                    var nomatch = $('.item_name:not(:contains("' + searchterm + '"))');             
                    match.addClass('selected');
                    nomatch.addClass('uk-hidden');


                } else {
                    $('.item_name').removeClass('uk-hidden');
                    $('.item_name').removeClass('selected');                
                }

            });

            var statematch = $('.item_name:contains("استان")');
            statematch.remove().parent();


              $(document).keypress(function(e) {
                       if(e.which == 13) {
                          var url1 = $('.item_name.selected:not(.uk-hidden) a').attr('href');
                          $(window.location).attr('href', url1);
                       }
                     });
        });

Answer 2

使用下面的代码。

 $('input[name="search"]').bind('keypress', function(e) {
    var code = e.keyCode || e.which;
     if(code == 13) { //Enter keycode
       var href = $(".ad-city-list").find(".selected:first").find("a:first").attr("href");
       if(href)
       window.location.href = href;
     }
});
