Chrome声称未定义简单功能 [英] Chrome claims simple function is undefined
问题描述
我在业余时间做了一个摩尔斯电码翻译器,并且第一次在Chrome中试用了它.调用translate()
函数时,Chrome将Uncaught TypeError: translate is not a function at HTMLInputElement.onclick (morse:28)
丢在我的脸上.其他功能按预期工作,可以从控制台调用translate()
而不出现问题.此外,它在Firefox中也能完美运行.
I've made a little morse code translator in my free time, and just tried it out in Chrome for the first time. When the translate()
function is called, Chrome throws Uncaught TypeError: translate is not a function at HTMLInputElement.onclick (morse:28)
in my face. The other fuctions work as expected, and translate()
can be called from the console without issue. In addition, it works perfectly in Firefox.
相关(我认为)HTML:
Relevant (I think) HTML:
<div id="mainspan">
<form id="morseForm">
<textarea id="morseInput" rows="8" cols="50"></textarea><br><br>
<input type="radio" name="trans" id="mtt" value="morseToText"><label for="mtt">Morse → text</label><br>
<input type="radio" name="trans" id="ttm" value="testToMorse"><label for="ttm">Text → morse</label><br>
<input type="button" onclick="translate()" value="Translate"><br><br>
<textarea id="morseOutput" rows="8" cols="50"></textarea><br>
</form>
</div>
还有JS:
function translate() {
if (document.getElementById("mtt").checked == true) {morseToText()};
if (document.getElementById("ttm").checked == true) {textToMorse()};
}
推荐答案
这可能是Chrome的不需要的功能",translate
似乎有一些特殊含义"事件,尽管通常没有定义
This is probably an "unwanted feature" of Chrome, translate
seems to have some "special meaning" event though it is usually undefined
<script>
function translate () {
alert('or nah');
}
</script>
<button onclick="translate()">
translate!
</button>
但是无效
<script>
function translate () {
alert('or nah');
}
window.onload = function() {
document.querySelector('button').addEventListener('click', translate);
}
</script>
<button>
translate!
</button>
有效-本质上相同,但显然不一样
works - essentially the same, but obviously not
最简单的解决方案
- 使用addEventListener方法将click事件添加到按钮,或者
- 不要使用名称
translate
