jquery 操作dom效率测试------html和append插入文档

 $(function () {
        var htmlResult = createHtmlContent(100);
        console.log(htmlResult)
        insertHtml.call($("#left"), "html()耗时：", htmlResult);
        insertHtml.call($("#right"), "append()耗时：", htmlResult);
    });

    function createHtmlContent(count) {
        var htmlContent = "";
        for (var i = 0; i < count; i++) {
            htmlContent += `<div>这是第${i + 1}个元素</div>`;
        }
        return htmlContent;
    }

    function insertHtml(type, htmlContent) {
        console.time(type);
        if (type === "html()耗时：") {
            this.html(htmlContent);
        } else if (type === "append()耗时：") {
            this.empty().append(htmlContent);
        }
        console.timeEnd(type);
    }
