javascript参数参考错误

Question

i was trying to make a photo gallery where user can click the link and show different photo but itry to put the parameters as a name but it keeps getting error says that said reference error but when i try to use number like 0,1,2,3,4,5 everything goes normal exactly like i want.My question is how to make the parameters to be a name instead of a number ? 我试图制作一个照片库，用户可以单击链接并显示不同的照片，但是试图将参数作为名称输入，但是它一直在显示错误，但仍表示该参考错误，但是当我尝试使用像0,1,2这样的数字时，3,4,5一切正常，就像我想要的一样。我的问题是如何使参数成为名称而不是数字？

  <body>
<img src="../bab2/images/Gusion.png" width="400px" alt="" id="gambar">
<a href="#" onclick="ganti(gusion)">1</a>
<a href="#" onclick="ganti(selena)">2</a>
<a href="#" onclick="ganti(2)">3</a>
<a href="#" onclick="ganti(3)">4</a>
<a href="#" onclick="ganti(4)">5</a>
<script type="text/javascript">
  function ganti(nama){
    var lokasi = '../bab2/images/' + nama + '.png';
    document.getElementById('gambar').src =lokasi;
  }
</script>

Answer 1

gusion and selena are names… specifically, they are variable names . gusion和selena是名称……具体地说，它们是变量名 。

If you want a string then you need to surround it with quotes . 如果您想要一个字符串，则需要用引号将其引起来。

Answer 2

If you want to pass names as parameters you need to pass them as Strings, ie, enter the name within quotes. 如果要将名称作为参数传递，则需要将其作为字符串传递，即在引号中输入名称。 Here is the modified code: 这是修改后的代码：

<a href="#" onclick="ganti('gusion')">1</a>
<a href="#" onclick="ganti('selena')">2</a>
