如何使用javascript（iphone）触发点击通话 [英] How to trigger click-to-call with javascript (iphone)

问题描述

我在移动网页中有一个链接，需要跟踪广告客户clickTag，然后激活点击通话。

I have a link in a mobile webpage that needs to track an advertiser clickTag and then activate click-to-call.

我有跟踪工作，但我不知道如何触发 tel：[phone]; with JavaScript的。有任何想法吗？这不是一个网络应用程序;这是一个标准的html页面。我可以使用jQuery。

I've got the tracking working but I don't know how to trigger the tel:[phone]; with javascript. Any ideas? This is not a web app; it's a standard html page. I can use jQuery.

更新

只需调用 window.open（tel：num）; 在点击后添加跟踪iframe不够可靠，因为有时调用对话框会在iframe完成加载之前打开。

Just calling window.open("tel:num"); after adding a tracking iframe on click was not reliable enough because sometimes the call dialog box would open before the iframe had finished loading.

window.open（tel：num）; 还打开一个新窗口然后打开调用对话框，这不是在iphone 3gs / 4上获得了极佳的用户体验。

window.open("tel:num"); also opens a new window then opens the call dialog box, which isn't a great user experience on iphone 3gs/4.

推荐答案

您是否可以控制跟踪iframe？如果是这样，你可以调用一个函数，该函数在加载后进行window.location调用。类似

Do you have any control over the tracking iframe? If so, you could call a function which makes the window.location call once it's loaded. Something like

$(document).ready(function() { window.iframe_loaded(); });

（如果它有jQuery），主脚本中的函数名为iframe_loaded window.location调用。

in the iframe code (if it has jQuery), and a function in your main script called iframe_loaded which does the window.location call.

如果您无法在iframe中设置代码但可以编辑iframe容器代码，那么您可以这样做......

If you can't set the code within the iframe but can edit the iframe container code, then you could do this...

<iframe id="whatever" onload="iframe_loaded();" width="400" height="200"></iframe>

...所以onload调用iframe_loaded（）做window.location ......

...so the onload calls iframe_loaded() which does window.location...

如果你无法控制iframe或其内容，那么简单的kludge就是在超时中包装window.location调用，即

If you don't have control over the iframe or its content, then easy kludge would be to just wrap the window.location call in a timeout, i.e.

setTimeout('window.location="tel:[phone]";', 500);

最后500将延迟半秒。 （如果你的iframe加载缓慢，请增加它。）它不是那么优雅，但可能工作正常，用户可能不会注意到一个小延迟！

The 500 at the end will delay it by half a second. (Increase it if your iframe is slow to load.) It's not as elegant, but might work fine and users probably won't notice a small delay!
