Cordova iOS不响应touchinput [英] Cordova iOS don't respond to touchinput
问题描述
我在iOS上创建了Cordova应用程序，当我尝试按下模拟器上的按钮或真实设备上时，应该向我显示该按钮已按下的警报。不幸的是没有发生什么，我不知道为什么。一些代码：
I have created a Cordova app on iOS and when I try to press the button on the simulator or on a real device is is supposed to show me an alert that the button has been pressed. Unfortunately nothing happens and I'm not quite sure why. Some code:
<html>
<head>

Customize this policy to fit your own app's needs. For more guidance, see:
https://github.com/apache/cordova-plugin-whitelist/blob/master/README.md#content-security-policy
Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src

function showAlert(){
alert("Button is pressed!");
}
</script>
<h1>This is an app</h1>
<button onClick="showAlert()">Press me!</button>
</body>
做一个令人难以置信的愚蠢的错误？
Can someone see if I am doing an incredible stupid mistake?
推荐答案
如果你使用5.0.0或更高版本， $ c>白名单系统。它包含 CSP （内容安全策略），防止inline-javascript工作。
If you are using 5.0.0 or higher, you are required to use the whitelist system. It covers CSP (Content Security Policy), which prevents inline-javascript from working.
您的HTML元素< button onClick =showAlert（）>按下我！< / button> 有一个 inline-javascript 元素。您不能使用Cordova 5.0.0。该限制是新的WebView库（ UIWebview 和 WKWebview iOS ）的一部分
Your HTML element <button onClick="showAlert()">Press me!</button> has an inline-javascript element. You canNOT use that as of Cordova 5.0.0. The restriction is part of the new WebView Library (UIWebview and WKWebview for iOS)
要在HTML中使用 inline-javascript ，您必须编写CSP异常。注意：这会让您的应用程式不安全。
To use the inline-javascript in your HTML you will have to write a CSP exception. NOTE: This will make your app insecure. You can add security by following the link just below.
以下是您的代码，将其添加到您的 index.html
< meta http-equiv =Content-Security-Policy
content =default-src *;
style-src'self ''unsafe-inline''unsafe-eval';
script-src'self''unsafe-inline''unsafe-eval';>
Here is your code, add it to your index.html
<meta http-equiv="Content-Security-Policy"
content="default-src *;
style-src 'self' 'unsafe-inline' 'unsafe-eval';
script-src 'self' 'unsafe-inline' 'unsafe-eval';">
