[英]What is the correct way to use the javascript .onclick function?
When using .onclick to run a function, it isn't executing it.当使用 .onclick 运行一个函数时,它并没有执行它。 Have I done something wrong?
我做错了什么吗?
<script>
const object1 = document.getElementById('object1');
const image2Path = "image2.svg";
object1.onclick = () => {
object1.src = image2Path;
}
</script>
<body>
<img id='object1' src="image1.svg">
</body>
I'm expecting image1 (which shows up successfully) to change to image2 when I click on the object.当我单击对象时,我期待 image1(成功显示)更改为 image2。
You need to bind the onclick handler correctly.您需要正确绑定 onclick 处理程序。 This would be a way to do it:
这将是一种方法:
<script>
function toogle()
{
const object1 = document.getElementById('object1');
const image2Path = "image2.svg";
object1.src = image2Path;
}
</script>
<body>
<img id='object1' src="image1.svg" onclick="toggle();">
</body>
const object1 = document.getElementById('object1'); const image2Path = "image2.svg"; object1.onclick = () => { object1.src = image2Path; }
<body> <img id='object1' src="image1.svg"> </body>
