未捕获的ReferenceError：在Wordpress中未定义jquery

Question

任何人都可以帮我解决这个问题。我在外部向我的WordPress网站添加了一个JS。它不会产生输出并在以下代码中引发错误。

请帮帮我，克服它。

var clock;

jquery(document).ready(function() {
    var currentDate = new Date();
    // Set some date in the past. In this case, it's always been since Jan 1
    var pastDate  = new Date(currentDate.getFullYear(), - 3, 4, 3);
    // Calculate the difference in seconds between the future and current date
    var diff = currentDate.getTime() / 1000 - pastDate.getTime() / 1000;

    clock = jquery('.clock').FlipClock(diff, {
        clockFace: 'MinuteCounter'
    });
});

JavaScript区分大小写。使用jQuery代替jquery：

jQuery(document).ready(function() {
    .
    .
    .

    clock = jQuery('.clock').FlipClock(diff, {
        clockFace: 'MinuteCounter'
    });
});
