I want the webview in my Chrome app to clear its cache every time it is started again. I tried using the clearData() function outlined here but the console reports that ...clearData is not a function. There was an answer here to someone who had the same problem, but that did not solve it. The getElementById part works, since I was able to change the webview's style with it. The problem is the clearData part.
html bit:
<webview class="w" id="webView" src="https://example.com"></webview>
javascript:
document.getElementById('webView').clearData({start:0},{cache:true});

I'm working in an EJS template and I need to determine the screen size. I'm using Grunt & Browserfy to compile (apologies if this is the wrong terminology). Using window.screen.width or window.matchMedia returns an error that window is not defined. What would be the best way to access this information?
Answering my own question: I understand now that EJS is rendered on the server so there is no screen to reference. I ended up using Javascript to accomplish what I needed since it's rendered in the browser. It's messier than I wanted but works nonetheless.
Try just using screen.width without the "window" in front.
I just removed AjaxControlToolkit v7 from my project, and therefore replaced the ToolkitScriptManager with the standard ScriptManager.
Now after postback on iframe in popup window all script functions (including jquery, $ etc) are undefined. Just about everything on the window object is undefined. The location is correct and all the script files are there in the head. I put a breakpoint in the script file and when it tries to call a function defined in that very same script file it is undefined.
Any ideas where to look?
Always ask: "What has changed?"
In my case, I no longer use the Modal Popup Extender with a PERMANENT div. I now use jquery dialog with a dynamic div that I destroy when we click an OK button.
It seems IE still tries to execute scripts after the IFRAME container has been removed from the DOM (with $(div).dialog("destroy").remove()). Chrome at least seems to behave differently and not try to run the scripts.

Issue with Iframe inside JQuery dialog only for IE

I´m setting the title of a popup window on ie9, but it´s not getting updated.
Strange thing is that inspecting the elements, the title is correctly setted, but the browser displays the url regardless.
Also, if I open the window like this:
window.open(url,"_blank") then it works
However:
window.open(url,"_blank",'height=200, width=400') (i.e with any specs setted) triggers that strange behaviour
Anyone has any clues on it? any workaround appreciated.
It only happens if the site is marked as trusted, and this solves it:
Trusted Site in IE - html title is ignored
I'm developing an app that loads a form from another website into an iFrame. The iFrame is set to 100% width and height while displayed. That website has JQTouch.
When I touch an input field in iOS 7 on the iPhone, the keyboard pops up and covers the input fields. It doesn't scroll, resize, or even let me scroll down to see the input field. If I type and then close the keyboard, nothing happens.
I've tried everything I've come across. Adding/removing height=device-height in the meta viewport tag didn't do anything. The thing that came closest to a solution was adding the preference "KeyboardShrinksView = true" in config.xml. That made it scroll (but not enough), and permanently pushes the site up about 20px or so.
I've been working on this for the last couple days with no solution in sight. Is this a bug? Is it the way JQTouch is interacting with PhoneGap Build?
UPDATE: Still no fix, but to test I took the form's page out of the iframe and set it using window.location.href="www.mywebsite.com"; They keyboard works in that situation. This is not a valid solution for me (yet), but may provide info on why it's not working.
UPDATE 2: I'm restructuring the app to use window.location.href, rather than an iframe or html object. This creates some small issues, but these are better than the keyboard not working. If anyone has an answer, I'd still like to see it.
Major Edit: I just realized the InAppBrowser plugin does NOT fix the keyboard bug alone. I did some more research, and this topic helped. I had to add "height=device-height" to every meta viewport tag. "width=device-width" should fix any problems viewing the site in mobile Safari. The final result is this:
<meta name="viewport" content="initial-scale=1, minimum-scale=1,
maximum-scale=1, user-scalable=0, height=device-height, width=device-width"/>
One of these also had a semicolon thrown in there, so be sure to check and double-check for syntax errors, as they may cause the problem.
If this doesn't work, there is another solution that you might try in place of or in addition to the meta viewport fix. It's several comments down in that topic I linked and involves some changes to the CSS. Changes to this didn't fix anything in my code, but it helped at least one person, so it's worth checking out if you still need a solution.
I tested this fix with iframe and object, and it didn't work--InAppBrowser is still necessary.
/Major Edit.
Here are some workarounds that worked for me:
Use the InAppBrowser plugin. This allows the app to interact with loadstart/loadstop/loaderror events in the loaded page within the InAppBrowser. This is the solution I suggest. However, with iOS 7, you will need to hide the status bar manually, the solution for which is here
OR Load the page using window.location.href = [website url]. If you don't need to worry about interacting with or returning to the app or linking to external sites (both of which I needed), this is the way to go. It's pretty simple, but lacks some of the functionality of the first solution.
OR Get rid of JQTouch. I wasn't able to do this, but much of it is redundant when you're building an app with PhoneGap.
I am building a web page and I have included Facebook's Like button. Works great in all browsers but not in Firefox. When clicked in Firefox, it creates an endless loop of opening and closing a facebook login window. This is a known issue that Facebook isn't looking like it will correct anytime soon.
Can anyone tell me what code I might write to hide the like button (or a div containing the like button) from Firefox only? I've never written code to detect a browser and then have my site function a certain way. Not a javascript guru here. Thanks!
You can do this using the navigator javascript object, but it sounds like you have deeper problems if the facebook like button is causing an endless loop of window loads. You most probably have other errors in your code. The button should work fine in firefox.
Here's how to text for firefox using the navigator object,
if (/Firefox[\/\s](\d+\.\d+)/.test(navigator.userAgent)){
// user using firefox
}
This code parses the userAgent string, the string that defines the user's browser, of the navigator object. It looks for a string of the format Firefox/x.x or Firefox x.x.
This should work for you
<div id="likeDiv">
my div
</div>
<script>
if (navigator.userAgent.indexOf("Firefox")!=-1)
{
// Remove the element from the dom
var Node1 = document.getElementById('likeDiv');
Node1.removeChild(Node1.childNodes[0]);
}
</script>
Hope this helps
