我已經(jīng)構(gòu)建了此功能，該功能在用戶單擊按鈕時(shí)執(zhí)行；它將一個(gè)列表和2個(gè)按鈕元素插入到以表格包裝的有序列表中。但是，每當(dāng)我單擊“生成”按鈕時(shí)，它都會(huì)立即生成新元素，然后立即重定向到表單的操作/處理php頁面，由于未填寫字段等，該頁面會(huì)重定向回到上一頁。 ，所以我對它為什么要處理表格感到困惑？這是我的JS函數(shù)：function spawnSilly() //spawn chapters function        {            var div = document.createElement("LI"); //creating elements            var input = document.createElement("INPUT");            var button = document.createElement("BUTTON");            var del_button = document.createElement("BUTTON")            input.setAttribute("type", "text");     //setting attributes            input.setAttribute("name", "chapterInput" + stringNumber);            input.setAttribute("placeholder", "Title");            input.setAttribute("id", "var timestamp = new Date().getUTCMilliseconds();")            button.setAttribute("type", "button");            button.setAttribute("onClick", "redirect()");            button.setAttribute("id", "var timestamp = new Date().getUTCMilliseconds();")            button.innerHTML = "Edit";            div.setAttribute("id", "var timestamp = new Date().getUTCMilliseconds();")            del_button.setAttribute("id", "var timestamp = new Date().getUTCMilliseconds();")            del_button.innerHTML = "Delete Chapter";            del_button.setAttribute("onClick", "removeElement(this.id)")            div.appendChild(input)      //appending to list            div.appendChild(button)            div.appendChild(del_button);            var chapterNumber = getCount(document.getElementById('spawnList'), false) //setting number of chapter            var number = $('#spawnList').children(); //fetching number of children in list            var stringNumber = String(number) //setting chapter number to string for name attribute in input            var list = document.getElementById("spawnList");            list.insertBefore(div, list.childNodes[number]); //inserting one after another            var newChapterNumber = chapterNumber + 1;  //setting elements class as their chapter number
