当我点击拇指时，显示我的函数staticthumb未定义。但实际上你可以看到我写的函数staticthumb我声明了staticthumb函数，但它仍然显示错误所以请帮助我。现在我很无助所以请帮助我，并尝试解决我的问题，并提前感谢。
答案 0 :(得分：0)
JavaScript中的函数声明具有Functional Scope，这意味着它只能从声明它的函数中访问。如果它未在函数中声明，则它在全局范围内。
您在匿名函数中声明了staticthumb函数，因此它只能在该范围内使用。最简单的解决方法是将函数声明移出匿名函数，这将污染您的全局变量空间（您通常希望避免这种情况，但这本身就是一个主题）
TL; DR;将您的staticthumb功能移到$ {（文档）.ready之前的<script>标记后面的第一行。
