类型错误$不是函数 [英] Type Error $ is not a function
问题描述
我在我的网站上使用基于jQuery的记忆游戏。它总体上运作良好,但我希望在最后显示再次播放链接和统计数据。我无法让代码工作。我看到了这个错误:
I am using a jQuery Based Memory Game on my site. It works well overall but I want a "Play Again" Link and stats at the end to show. I cannot get that code to work. I see this error:
TypeError: $ is not a function
[Break On This Error]
var game = $('div.slashc-memory-game'); // get the game
这是JS:
// this script shows how you can get info about the game
var game = $('div.slashc-memory-game'); // get the game
var info = $('p#info').find('span'); // get the info box
var playAgain = $('a#play-again').css('visibility', 'hidden'); // get the play again link
// format time like hh:mm:ss
var formatTime = function(s)
{
var h = parseInt(s / 3600), m = parseInt((s - h * 3600) / 60); s = s % 60;
return (h < 10 ? '0' + h : h) + ':' + (m < 10 ? '0' + m : m) + ':' + (s < 10 ? '0' + s : s);
}
// listen for game 'done' event
game.bind('done', function(e)
{
// show basic stats
var stats = game.slashcMemoryGame('getStats');
info.html('Success ! Number of clicks : ' + stats.numClicks + ', elapsed time : ' + formatTime(parseInt(stats.time / 1000)) + '.');
playAgain.css('visibility', 'visible'); // show link
});
// play again action
playAgain.click(function(e)
{
playAgain.css('visibility', 'hidden'); // hide link
info.html('Memory Game, click to reveal images'); // reset text
game.slashcMemoryGame('restart'); // restart game
e.preventDefault();
});
这是小提琴
推荐答案
尝试用jQuery()替换$(),看看你是否继续得到这个错误。指示它不是函数的错误意味着jQuery文件尚未加载或者$ name被故意释放。
Try replacing $() with jQuery() and see if you continue to get this error. The error indicating that it isn't a function means that either the jQuery file was not loaded yet or the $ name was freed intentionally.
如果jQuery()函数没有工作,确保您在脚本块/文件之前加载jQuery文件。
If jQuery() function doesn't work, make sure that you are loading the jQuery file before your script block/file.
