我正在尝试在html中的input =“image”上运行javascript menthod。我在html中的代码如下所示：
onclick="manageHandlers('Unassign'); document.getElementsByName('manageHandlers')[0].submit(); "
在我的javascript中，方法是这样的：
function manageHandlers(parameter){
alert("It's working: "+parameter);
}
我有什么问题吗？我可以在昨天知道这个工作，但今天它没有做任何事情。
感谢您的关注！
完整的HTML代码：

答案 0 :(得分：3)
这是错的：
onclick="manageHandlers('Unassign');
document.getElementsByName('manageHandlers')[0].submit();"
我之前从未见过这样的东西..如果它确实可能并且我确实错过了某些东西，那么我敢打赌很少这样做，因为不将你的js代码与内容层（HTML）分开是不好的做法。
无论如何，onclick是一个事件处理程序。您通常会分配一个在单击时执行的函数。
如果我是你，我不会做内联javascript。但如果你真的想让它保持内联，那么你可以试试这个：
function manageHandlers(parameter){
alert('blabla' + parameter);
document.getElementsByName('manageHandlers')[0].submit();
}
和onclick，你可以做onclick="manageHandlers('Unassign');"希望有帮助..
