用于计数:
var get_fb = (function() {
var counter = 1;
return function(){
var feedback = $.ajax({
...
}).responseText;
$('#BuzFeed').append("<div id='" + counter + "'>" + feedback + "</div>");
}
})();
get_fb();
并自动删除,之后
var $buzfeed = $('#BuzFeed').append("<div id='" + counter + "'>" + feedback + "</div>");
添加
var $buzfeedDivs = $buzfeed.children('div');
if ($buzfeedDivs.length > 10) { $buzfeedDivs.first().remove(); }
此外,您的代码使用了一些不太好的做法。重写,包括我的补充将是:
var get_fb = (function() {
var counter = 0;
var $buzfeed = $('#BuzFeed');
return function(){
$.ajax({
type: "POST",
dataType: "html", // based on chat
url: "algorithm.php"
}).done(function(feedback) {
counter += 1;
var $buzfeedresults = $("<div id='BuzFeedResult" + counter + "'></div>");
$buzfeedresults.text(feedback);
$buzfeed.append($buzfeedresults);
var $buzfeedDivs = $buzfeed.children('div');
if ($buzfeedDivs.length > 10) { $buzfeedDivs.first().remove(); }
setTimeout(get_fb, 8000);
}).fail(function(jqXhr, textStatus, errorThrown) {
var $buzfeedresults = $("<div id='BuzFeedError'></div>");
$buzfeedresults.text('Error: ' + textStatus);
if (typeof console !== 'undefined') {
console.error(jqXhr, textStatus, errorThrown);
}
});
};
})();
get_fb();
