我收到错误&#34; 未捕获的ReferenceError:未定义dispatchRegister &#34; 我怀疑功能不在全球范围内,但我如何解决这个问题呢?
答案 0 :(得分:2)
Script-tags documentation说明了src-attribute:
此属性指定外部脚本的URI;这可以用作直接在文档中嵌入脚本的替代方法。 如果脚本元素指定了src属性,则不应在其代码中嵌入脚本。
因此,删除src并将外部脚本添加为单独的脚本标记:
<script src="https://sdk.amazonaws.com/js/aws-sdk-2.7.20.min.js"></script>
<script>
function dispatchRegister() {
console.log("Here I am!");
}
</script>
<input type="button" value="Register" id="submit" onclick="dispatchRegister()" />

因为您将src设置为src="https://sdk.amazonaws.com/js/aws-sdk-2.7.20.min.js"
尝试像这样添加dispatchRegister()
,它会起作用:
<script>
function dispatchRegister() {
//Some AWS lib code
}
</script>
