&引用；ReferenceError:“未定义：”；将javascript添加到vue组件时<；脚本>；标签

尝试将代码添加到自动展开文本框时出现此错误-来自此代码笔：。 我需要以不同的方式添加它吗？ 它当前位于vue组件文件中的脚本标记之间

确保您正在加载jquery库，您可以按照这个或这个进行操作。

我使用了这段代码，这段代码运行得非常好

注意：在笔设置->JS选项卡中，它包括

//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.JS

var autoExpand = function (field) {

    // Reset field height
    field.style.height = 'inherit';

    // Get the computed styles for the element
    var computed = window.getComputedStyle(field);

    // Calculate the height
    var height = parseInt(computed.getPropertyValue('border-top-width'), 10)
                 + parseInt(computed.getPropertyValue('padding-top'), 10)
                 + field.scrollHeight
                 + parseInt(computed.getPropertyValue('padding-bottom'), 10)
                 + parseInt(computed.getPropertyValue('border-bottom-width'), 10);

    field.style.height = height + 'px';

};

document.addEventListener('input', function (event) {
    if (event.target.tagName.toLowerCase() !== 'textarea') return;
    autoExpand(event.target);
}, false);
