I make a form generator. And the question arose. I have a button that adds input. This input has a button with settings. When I click on it, everything is fine, but when I add another input, when I click on the button, the settings are opened, not the 2nd input, but the 1st one. Why? Help me please.
function addInput() { var code = document.querySelector('.code'); var block = document.getElementById('add-form'); var posInput = document.getElementById('pos-input'); var input = document.createElement('input'); var titleInput = document.createElement('span'); var edit = document.createElement('button'); var div = document.createElement('div'); var changeInput = document.createElement('input'); var label = document.createElement('label'); var changeTitle = document.createElement('button'); var avrBlock = document.createElement('div'); var editBlock = document.createElement('div'); input.id = "input"; input.type = "text"; titleInput.className = "title-input"; titleInput.innerHTML = "Имя"; edit.className = "edit"; div.className = "block-btn"; changeInput.id = "change-input"; changeInput.type = "text"; label.innerHTML = "Заголовок поля:"; changeTitle.id = "change-title"; changeTitle.innerHTML = "Поменять заголовок"; avrBlock.className = "avrage-block"; editBlock.className = "edit-block"; changeTitle.onclick = function() { var changeInput = document.getElementById('change-input').value; var codeResult = document.getElementById('input-title-name'); var titleInput = document.querySelector('.title-input'); codeResult.innerHTML = changeInput; titleInput.innerHTML = changeInput; } avrBlock.appendChild(titleInput); avrBlock.appendChild(div); avrBlock.appendChild(input); avrBlock.appendChild(edit); avrBlock.appendChild(label); avrBlock.appendChild(changeInput); avrBlock.appendChild(changeTitle); avrBlock.appendChild(editBlock); div.appendChild(input); div.appendChild(edit); editBlock.appendChild(label); editBlock.appendChild(changeInput); editBlock.appendChild(changeTitle); posInput.appendChild(avrBlock); block.appendChild(posInput); edit.onclick = function() { var dropDown = document.querySelector(".edit-block"); if (dropDown.currentStyle) { var displayStyle = dropDown.currentStyle.display; } else if (window.getComputedStyle) { var displayStyle = window.getComputedStyle(dropDown, null).getPropertyValue("display"); } if (displayStyle == "none") { dropDown.style.display = "block"; } else { dropDown.style.display = "none"; } } code.innerHTML += " <span class='title-input'>" + "<span id='input-title-name'>Имя</span>" + "</span><input id='input' type='text'>" + '<br>'; } function increaseHeight() { var block = document.getElementById('add-form'); block.style.height = "auto"; } @import url('https://fonts.googleapis.com/css?family=Yanone+Kaffeesatz'); * { margin: 0; padding: 0 } #container { float: left;
