有人可以帮我这个剧本吗? 我希望每当用户点击历史记录1 ..它将提醒h1 该脚本适用于Firefox和IE,但不适用于Chrome:(

如果您想在Chrome,IE等中使用onClick
选项元素,则必须使用简短修复:将select元素的onChange
属性设置为"this.options[this.selectedIndex].onclick()"

使用onchange代替onclick选择列表。
<select name="history" id="history" onchange="historyChanged(this);">
<option value="history1">history 1</option>
<option value="history2">history 2</option>
<option value="clearhistory">Clear History</option>
</select>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
function historyChanged() {
var historySelectList = $('select#history');
var selectedValue = $('option:selected', historySelectList).val();
alert(selectedValue);
if (selectedValue == 'clearHistory') {
historySelectList.form.submit();
}
}
$(function() {
alert('my alert');
$('select#history').change(historyChanged);
});
</script>

在select而不是每个选项上使用onChange。这是jsfiddle http://jsfiddle.net/tBjkg/
<select name="history" id="history" onChange="alert(this.value);">
<option value="history1">history 1</option>
<option value="history2">history 2</option>
<option value="clearhistory">Clear History</option>
</select>
警报(this.value)指的是当前所选的选项中的选项值。

在某些浏览器中,
第二次选择相同的选项,
没有onchange-event抛出。
这有助于:
<select onchange="alert/*orwhateveryoudowith:*/(this.value);/*but set:*/this.selectedIndex=0">
<option disabled selected>Choose your Plan</option>
<option value=1>Plan 1</option>
<option value=2>Plan 2</option>
<option value=3>Plan 3</option>
</select>

尽管选定的解决方案有效,但这是一种更清晰,更轻松的方法:
<select name="history" id="history" >
<option value="history 1">history 1</option>
<option value="history 2">history 2</option>
<option value="clearhistory">Clear History</option>
</select>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#history').on('change', function() {
if ( this.value == 'history 1')
{
alert('h1');
// You can also do anything here
}
if ( this.value == 'history 2')
{
alert('h2');
// You can also do anything here
}
if ( this.value == 'clearhistory')
{
this.form.submit();
// You can also do anything here
}
});
});
</script>
