这有点疯狂......
我有一个html代码，使用on-click调用一个函数，它有效！
Whan我想添加另一个函数或重命名相同的函数（在on-click调用中也是如此），它给了我这个错误：
[dom-bind::_createEventHandler]: listener method `name of function` not defined
所有要做的就是重命名该功能。 Whare你定义＆＃39;功能＆＃39;？
我使用的是聚合物1.0
这是给我错误的代码。

感谢。
答案 0 :(得分：0)
试试这个：
<paper-button onclick="testButton">Signup</paper-button>
并且最好使用ontab而不是onclick。

我错了。实际上，on-click是正确的倾听者。
我实际上认为这是你的HTML标记或你的Polymer版本的问题。我尝试了这段代码，它对我有用：
<body unresolved class="fullbleed layout vertical" scroll="no" style="overflow: hidden">
<span id="browser-sync-binding"></span>
<template is="dom-bind" id="app">
<paper-button on-click="testButton">Signup</paper-button>
</template>
<script src="scripts/app.js"></script>
</body>
你也错过了一个simicolon：
app.testButton = function() {
console.log('login?');
}; // here
如果它不适合你，也许你需要开始一个新项目。
