javascript - 使用 Enter 键提交 JQuery 表单

Question

我尝试过各种解决方案，但没有一个适合我的具体情况!我怎样才能做到这一点，以便当用户按下“Enter”时，表单会提交和搜索。

顺便说一句，我正在使用带有 AJAX 的烂番茄 API。

表格

<form name="myform" action="" method="GET"><h3 class="white">Search for a movie here!:</h3><br> 
    <input type="text" id="inputbox" value="">&nbsp;
    <input type="button" id="button" value="Go!" onClick="filmlist(this.form)">
</form>

ajax.js

function filmlist(form) {
    $('#films table').empty(); //removes previous search results before adding the new ones.
    var apikey = "APIKEY";
    var baseUrl = "http://api.rottentomatoes.com/api/public/v1.0";
    var moviesSearchUrl = baseUrl + '/movies.json?apikey=' + apikey;
    var query = form.inputbox.value; //uses the value from the input box as the query search
    $(document).ready(function () {
        // sends the query
        $.ajax({
            url: moviesSearchUrl + '&q=' + encodeURI(query),
            dataType: "jsonp",
            success: searchCallback
        });
    });
    // receives the results
    function searchCallback(data) {
        $('#films table').append('Found ' + data.total + ' results for ' + query);
        var movies = data.movies;
        $.each(movies, function (index, movie) {
            $('#films table').append('<tr><td width="70" rowspan="2"><a href="' + movie.links.alternate +
                '" title="Click here to view film information for ' + movie.title + '."><img class="ajaximage" src="' + movie.posters.thumbnail + '" /></a></td><td class="ajaxfilmlisttitle"><h3><a href="' + movie.links.alternate +
                '" title="Click here to view film information for ' + movie.title + '.">' + movie.title + '</a></h3>Release year: ' + movie.year + '</td></tr><tr><td class="ajaxfilmlistinfo">Audience Score: ' + movie.ratings.audience_score +
                '<br>' + 'Cinema Release Date: ' + movie.release_dates.theater +
                '<br>Runtime: ' + movie.runtime + ' minutes</td></tr>');
        });
    }
}

我会试一试，这是一个更完整的解决方案，适用于整个“听按键输入以提交”，我在跨浏览器工作时遇到了一些问题，也许这会为你解决。

根据您的代码，这应该可以正常工作。

  $('#inputbox').live("keypress", function(e) {
     var code = (e.keyCode ? e.keyCode : e.which);
     if (code == 13) {
        e.preventDefault();
        e.stopPropagation();
        $(this).closest('form').submit();
     }
  });
