未捕获的 ReferenceError：jquery 未在 Wordpress 中定义

Question

谁能帮我解决这个问题。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。

请帮助我克服它。

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'
    });
});

Answer 1

JavaScript 区分大小写。使用jQuery 而不是jquery：

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

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