innerHTML(或其他方法):使用< input/>将li附加到ul.包括属性 [英] innerHTML (or other method): append li to ul, with <input/> including attributes

问题描述

document.getElementById('addplace').addEventListener('click', function() {
    addplace();
  });

function addplace() {
  var node = document.createElement("li"); // Create a <li> node
  node.innerHTML = "<input/>"               
  document.getElementById("waypoints").appendChild(node);
}

<ul id="waypoints"></ul>
<input type="submit" id="addplace" />        
        

当单击按钮时，以上代码段已成功将输入字段添加到ul中.但是，当我将属性添加到输入字段时，提交按钮将不再起作用.

The above snippet successfully adds an input field to the ul when the button is clicked. However when I add attributes to the input field the submit button no longer works.

    document.getElementById('addplace').addEventListener('click', function() {
        addplace();
      });

    function addplace() {
      var node = document.createElement("li"); // Create a <li> node
      node.innerHTML = "<input class="field" placeholder="Where to begin?" onFocus="geolocate()" type="text" />"               
      document.getElementById("waypoints").appendChild(node);
    }

    <ul id="waypoints"></ul>
    <input type="submit" id="addplace" />        

谢谢.

推荐答案

您必须对字符串内的双引号进行转义("\"")或使用双引号("'")代替双引号进行修复您的问题.

You have to either escape("\"") the double quotes inside the string or use single quotes("'") in the place of double quotes to fix your issue.

function addplace() {
  var node = document.createElement("li"); // Create a <li> node
  node.innerHTML = "<input class='field' placeholder='Where to begin?' onFocus='geolocate()' type='text' />"               
  document.getElementById("waypoints").appendChild(node);
}

通过双引号转义的解决方案，

The solution by escaping the double quotes,

node.innerHTML = "<input class=\"field\" placeholder=\"Where to begin?\" onFocus=\"geolocate()\" type=\"text\" />"
