GWT - Show a custom dialog before window close?
I need to prompt the user to a site usability survey when the user navigate away from the site or try to close the site window. For example, when the user closes the window of my site, I want to show a prompt to say "do you want to take a survey?" , if the user clicks yet, open a new window with the survey link.
Is there a way in GWT to achieve that?
I have tried using Windows.addWindowCLosingHandler
but that only gave me the ability to set a message to ask if the user want to stay on the site or now using ClosingEvent event , event.setMessage("sure?");
thanks开发者_开发知识库
You can use window.onunload but that will be called whenever the user changes the page
Also see here: How to catch user leaving a page and cancelling it
Use the unload method on the body:
<body onUnload="unloadFunction(); return false;">
Then something like this for your js:
function unloadFunction()
{
if (confirm("Would you like to take our servey?"))
{
window.location.href = 'location_of_your_survey'
}
return false;
}
加载中,请稍侯......
