WP7 Web浏览器控件中无法通过Javascript显示警报 [英] Unable to show alert via Javascript in WP7 web browser control
问题描述
我正在尝试使用WP7中的Web浏览器控件在网页中使用javascript显示警报框.警报没有弹出.代码有什么问题吗?或者WP7根本不支持它?
I am trying to show alert box using javascript in a webpage using web browser control in WP7. The alert is not popping up. Is there anything wrong in the code or WP7 doesn't support it at all?
< phone:WebBrowser名称="browser" IsScriptEnabled ="True" ScriptNotify ="browser_ScriptNotify" Source ="Default.html"/>
<phone:WebBrowser Name="browser" IsScriptEnabled="True" ScriptNotify="browser_ScriptNotify" Source="Default.html"/>
内部Default.html
Inside Default.html
<html><br>
<head><br>
</head><br>
<body onload="onLoad()"><br>
<script type="text/javascript"><br>
function onLoad() {<br>
alert("hello");<br>
}<br>
</script><br>
</body><br>
</html>
推荐答案
这是我解决的方法，我将javascript注入了要导航到的网页上，并覆盖了警告和确认框
This is how I solved it, I injected the javascript onto the webPage to which I navigate, and overrided the alert and confirm boxes
window.alert = function(__msg){window.external.notify(' + __msg + ');};
然后在脚本通知功能中使用MessageBox显示该消息.我希望它也能帮助其他人.先前的答案是一种解决方法，这就是我认为是解决问题的正确方法
Then in the script notify function displayed that message using MessageBox. I hope it helps others too. The previous answer was a workaround, this is what I feel is the correct solution to my problem
