Javascript 基于关键字查找特定元素并推送到数组

我尝试查找所有输入元素，并根据元素的id搜索id以匹配特定关键字。如果找到匹配项，我希望将元素放入数组targetNodese中。变量节点包含所有输入，当我记录数组时，我得到[-1，-1，0，0]，这告诉我它找到了带有关键字调查答案的特定输入元素。但是我如何访问元素属性，而不是仅仅告诉我它找到了它

JS

将节点推入数组，而不是indexOf调用的结果：

这样做：-

var targetNodes, nodes, count;

targetNodes = [];

nodes = document.getElementsByTagName("input");
for (count = 0; count < nodes.length; count++) {
    node = nodes[count].id.indexOf("survey-answer");
    if (node == 0)
      targetNodes.push(nodes[count]);
}

alert(targetNodes);

参考和其他

下面是一个JSFIDLE来测试这一点：

var targetNodes, nodes, count;

targetNodes = [];

nodes = document.getElementsByTagName("input");

for (count = 0; count < nodes.length; count++) {
    node = nodes[count].id.indexOf("survey-answer");
    targetNodes.push(node);
}

console.log(targetNodes);

for (count = 0; count < nodes.length; count++) {
  var node = nodes[count].id.indexOf("survey-answer");
  if (node != -1) {
    targetNodes.push(nodes[count]);
  }
}

var targetNodes, nodes, count;

targetNodes = [];

nodes = document.getElementsByTagName("input");
for (count = 0; count < nodes.length; count++) {
    node = nodes[count].id.indexOf("survey-answer");
    if (node == 0)
      targetNodes.push(nodes[count]);
}

alert(targetNodes);

if (node == 0)
  targetNodes.push(nodes[count].value);

var targetNodes, nodes, count;

targetNodes = [];

nodes = document.getElementsByTagName("input");

for (count = 0; count < nodes.length; count++)
{
    node = nodes[count].id.indexOf("survey-answer");

    if (node != -1)
    {
        targetNodes.push(nodes[count]);
    }
}

for (count = 0; count < targetNodes.length; count++)
{ 
      alert("id: " + targetNodes[count].id +
            ", name: " + targetNodes[count].name + 
            ", value: " + targetNodes[count].value);
}
