选择onchange适用于Chrome和Opera，但它不适用于Firefox。你介意帮帮我吗？我该怎么做才能为所有浏览器修复它？

Answer 1

您永远不会删除selected标记上的属性option。因此，在使用您的脚本后，您的html代码如下所示：

<select id="tehlike_sinifi"> 
    <option value="1" selected="selected">"Az Tehlikeli"</option>      
    <option value="2" selected="selected">"Tehlikeli"</option> 
    <option value="3" selected="selected">"Çok Tehlikeli"</option>     
</select>

Firefox不知道选择哪个选项。

尝试使用函数val()，而不是设置属性selected。

From jQuery documentation

[jQuery.val]检查或选择所有单选按钮，复选框，并选择与该组值匹配的选项。

使用函数val()，它工作正常。

if ($.inArray($("#nace_kod").val(), aztehlikeliNace) >= 0) {
    $("#tehlike_sinifi").val(1);
}
if ($.inArray($("#nace_kod").val(), tehlikeliNace) >= 0) {
    $("#tehlike_sinifi").val(2);
}
if ($.inArray($("#nace_kod").val(), coktehlikeliNace) >= 0) {
    $("#tehlike_sinifi").val(3);
}

将您的功能脚本保留在<iframe id="vt" width="420" autoplay="false" height="345" src="http://cache4.asset-cache.net/xd/468140002.mp4?v=1&c=IWSAsset&k=2&d=72990B68305E4FDFEE95B69A879131BCD6D7111452E48A17C03F8342D660D5A451EBC1DEC2A827C9&b=RTdG" frameborder="0" allowfullscreen></iframe>，否则会出现错误head
