Question

所以我试图让页面显示按下每个按钮的不同段落。但是，我不断收到一些错误，其中按钮将无法正常运行该功能。实施例

function examplefunction() {
  document.getElemtentById("paragraphtobechanged").innerHTML = "When I put more "" it fails in other words it will not write this part."
  }

<button onclick="examplefunction()">Change Paragraph</button>
<p id="paragraphtobechanged"></p>

Answer 1

应该是：

function examplefunction() {
  document.getElemtentById("paragraphtobechanged").innerHTML = "When I put more \"\" it fails in other words it will not write this part."
  }

您需要转义双引号。或者你可以这样做：

function examplefunction() {
      document.getElemtentById("paragraphtobechanged").innerHTML = 'When I put more "" it fails in other words it will not write this part.'
      }

Answer 2

@TheDude走在正确的轨道上，但还有别的东西。您在示例中拼错了元素：

function examplefunction() {
                V
  document.getElementById("paragraphtobechanged").innerHTML = "When I put more \"\" it fails in other words it will not write this part."
  }

Answer 3

这里的问题是实际的字符串。

// Option 1
"When I put more \"\" it fails in other words it will not write this part."


// Option 2
'When I put more "" it fails in other words it will not write this part.'

注意：选项2适用于您的情况，但如果您在实际字符串中使用两个单引号和双引号，则必须转义其中一个。
