javascript onclick提醒不在chrome中工作

Question

<select name="history" id="history" >
 <option value="history 1" onClick="alert('h1');">history 1</option>
 <option value="history 2" onClick="alert('h2');">history 2</option>
 <option value="clearhistory" onClick="this.form.submit();" >Clear History</option>
</select>

有人可以帮我这个脚本吗？我希望每当用户点击历史记录1 ..它将警告h1脚本在firefox和IE中工作,但不在Chrome中:(

Answer 1

如果要onClick在Chrome,IE等中使用选项元素,则必须使用short fix:onChangeselect元素的set 属性"this.options[this.selectedIndex].onclick()"

Answer 2

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>

Answer 3

在select而不是每个选项上使用onChange.这里是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>

alert(this.value)指的是当前所选的select中的选项的值.
