我正在使用rottentomatoes电影API和twitter的typeahead插件使用bootstrap 2.0。我已经能够整合API,但我遇到的问题是在每个keyup事件之后调用API。这一切都很好,但是我宁愿在一个小暂停之后拨打电话,让用户先输入几个字符。
以下是我在keyup事件后调用API的当前代码:
var autocomplete = $('#searchinput').typeahead()
.on('keyup', function(ev){
ev.stopPropagation();
ev.preventDefault();
//filter out up/down, tab, enter, and escape keys
if( $.inArray(ev.keyCode,[40,38,9,13,27]) === -1 ){
var self = $(this);
//set typeahead source to empty
self.data('typeahead').source = [];
//active used so we aren't triggering duplicate keyup events
if( !self.data('active') && self.val().length > 0){
self.data('active', true);
//Do data request. Insert your own API logic here.
$.getJSON("http://api.rottentomatoes.com/api/public/v1.0/movies.json?callback=?&apikey=MY_API_KEY&page_limit=5",{
q: encodeURI($(this).val())
}, function(data) {
//set this to true when your callback executes
self.data('active',true);
//Filter out your own parameters. Populate them into an array, since this is what typeahead's source requires
var arr = [],
i=0;
var movies = data.movies;
$.each(movies, function(index, movie) {
arr[i] = movie.title
i++;
});
//set your results into the typehead's source
self.data('typeahead').source = arr;
//trigger keyup on the typeahead to make it search
self.trigger('keyup');
//All done, set to false to prepare for the next remote query.
self.data('active', false);
});
}
}
});
是否可以设置一个小延迟并避免在每个键盘后调用API?
