从此脚本中删除 onclick 事件的最简单方法是什么？
下面的脚本使用谷歌翻译从一种语言翻译成另一种语言。
我希望能够将语言设置为
Request.Form("language")
所以当我提交表单时它会设置语言。 (我可以这样做，所以这不是问题，但是一旦设置了这种语言，我希望脚本自动翻译文本。
类似的东西
<body onload="">
或
document.ready or
translate.ready
但是我不是 100% 确定如何执行此操作:
<script type='text/javascript'>
google.load("language", "1");
var translator = false;
function init(){
var str = $("source").innerHTML;
var triggerCollection = $("langSelect").select("li");
triggerCollection.invoke("observe", "click", handleTriggerClick);
translator = new Translator("source", "p,ul");
translator.addEventListener("complete", function(obj){
//console.log("The translation has finished %o", obj);
{
document.form1.g_content_text.value = $("source").innerHTML;
}{
//document.form1.submit();
}
});
translator.addEventListener("begin", function(obj){
//console.log("Translation has begun! %o", obj);
});
//console.log(translator.textNodeCollection);
}
function handleTriggerClick(e){
var lang = e.element().getAttribute("lang"); // This is the language to translate to!
var str = $("source").innerHTML;
translator.translate(lang);
}
function insertToForeign(obj){
$("display").innerHTML = obj.translation;
}
google.setOnLoadCallback(init);

如果您单击li，它会设置语言并启动该功能:
<ul id="langSelect">
<li lang="de">German</li></ul>
另一个解决方案可能是模拟用户单击 li 命令，但我也不知道如何执行此操作!

我认为部分问题出在这里:
triggerCollection.invoke("observe", "click", handleTriggerClick);
最佳答案
听起来您对 dom:loaded 感兴趣事件。
document.observe("dom:loaded", function() {
translator.translate($('langselect').getAttribute('lang'));
});
或者，如果您知道语言代码，则可以直接输入它。以德语为例:
translator.translate('de');
