函数不会从html内的onclick中执行 [英] Function doesn't execute from an onclick inside the html
问题描述
这可能非常容易，但我对JavaScript很陌生，这让我感到非常紧张。
我的问题，为什么不能这样工作：
http://jsfiddle.net/Ye9tG/
< input type =buttonid = buttvalue =Buttononclick =getThought（）;/>
如果直接将onclick添加到JavaScript中，它可以正常工作：
document.getElementById（butt）。onclick = getThought;
预先致谢。 您的 getThoughts 函数未定义，因为您的JavaScript是设置为执行 onLoad 。请参阅jsFiddle左上角的下拉菜单。选择无包装< head> 来解决问题： http://jsfiddle.net/Ye9tG/1/
另外，请始终查看浏览器的控制台以检查错误。在这种情况下，您会看到一个 Uncaught ReferenceError：单击该按钮时，getThought未定义错误。
this is probably stupidly easy but I'm very new to JavaScript and it's driving me nuts.
My question, why doesn't this work: http://jsfiddle.net/Ye9tG/
<input type="button" id="butt" value="Button" onclick="getThought();"/>
It works fine if I add the onclick directly into the JavaScript:
document.getElementById("butt").onclick = getThought;
Thanks in advance.
Your getThoughts function isn't defined, because your JavaScript is set to execute onLoad. See the dropdown menu in the upper left of jsFiddle. Select "No wrap - in <head>" to resolve the issue: http://jsfiddle.net/Ye9tG/1/
Also, always take a look at your browser's console to check for errors. In this case, you'll see a Uncaught ReferenceError: getThought is not defined error when clicking the button.
