在更改事件上启用电话功能(jQuery)

问题描述：

我正在尝试在更改事件(HTML <select>标记)上启用电话功能，以便引用适当的"tel:"值.

I'm trying to enable the phone call functionality on change event (HTML <select> tag) so as to reference the appropriate "tel:" value.

我使用默认浏览器在 Android (版本 2.2 和 4.0 )上进行了测试:我没有得到想要的效果.

I run a test on Android (both version 2.2 and 4.0), using the default browser: I did not get the desired effect.

下面是我的代码:

HTML

<select class="call-us-options">
    <option value="">Select a branch:</option>
    <option value="branch-a">Branch A</option>
    <option value="branch-b">Branch B</option>
    <option value="branch-c">Branch C</option>
</select>
<a class="phone branch-a" href="tel:(22) 2222-222" title="Branch A">Branch A</a>
<a class="phone branch-b" href="tel:(33) 3333-3333" title="Branch B">Branch B</a>
<a class="phone branch-c" href="tel:(44) 4444-4444" title="Branch C">Branch C</a>

jQuery

$('.call-us-options').on('change', function() {
    if($(this).val()) {
        alert($('.'+$(this).val()).html());
        $('.'+$(this).val()).trigger('click');
    }
});

这是JSFiddle: http://jsfiddle.net/CZ3WF/1/

有没有有效的方法来实现这一目标?

Is there any effective way to achieve that?

答

您是否尝试将window.location = "tel:(44) 4444-4444"(无论数字是否位于与selectIndex相对应的锚点中)和onChange事件用于<select>?

Did you try window.location = "tel:(44) 4444-4444" (whatever the number is in the anchor corresponding to the selectIndex) with the onChange event for <select>?

click()仅会触发javascript事件处理程序，而不会实际转到该URL.我不确定这是否行得通，但您可以尝试一次window.location.

click() will only trigger javascript event handlers and will not actually go to that URL. Im not sure if this would work but can you try window.location once.
