I have placed the HTML Resource files and java script files with the project files in my iphone application. My objective is to build an application which has UIWebview which loads when we tab on the app icon. The UIWebView should actually load the local html content that I have in the resource folder. I can see the HTMl content in the webview but its not running the Javascript..
Checkout stringByEvaluatingJavaScriptFromString: in the
UIWebView Class Reference
Her the actual problem comes with adding the files(javascript and css) in the project. while adding files following option should be clicked that showed in the following image.

I have a html file located locally in the Library directory of the device and some images in the same directory. so when I open the webkitview in a simulator it loads the images perfectly but when I use a device the html page is loaded but the images are not loaded.this is my html :
<html><head><script src='./test.js'></script></head><body><img src='./sample_attachment.jpg' alt='Girl in a jacket' /><body><html>
and this is how I load the web view:
webView.loadFileURL(path, allowingReadAccessTo: path)
I have also enabled the Allow Arbitrary Loads in info.plist.
Thank you for your help !
I found the solution it can help anyone of you:
the first path in webView.loadFileURL(firstPath, allowingReadAccessTo: secondPath) is the path to the html file and the second path is the path to resources that you are allowed to open, the problem I was putting the same path that's why only the html page is loaded (I don't know why the simulator load the ressources correctly) but when I put the path to the directory in the second path it can access all the resources and load them perfectly.
In my JavaFX Application I generate a barcode with barcode4j by Apache, save it as png image in the directory /data/images/ and embed it in a web page which is shown on a JavaFX WebView.
After generating the barcode I embend it into the webpage using the following Javascript-Code:
path = "file:/" + path.replace(/\\/gi,"/");
var barcodeElement = document.getElementById("productBarcode");
barcodeElement.setAttribute("src", path );
barcodeElement.style.display = "inline-block";
I use the absolute path C:\path\to\java-program\data\myimage.png and build a file-URL from it.
Using this in Eclipse works without any problems. But when I build my project and start it from my jar-file the image is not shown. But the problem is not, that the path is incorrect or that generating the picture does not work, so that there is some kind of "not found" error. The place where the image should be is just white with a light border around.
And now the strangest part: If you right click on the image and choose "open in new window" the image is shown!
Does someone has an idea about that?
Thank you very much in advance!
My understanding is that the WebView won't let a page loaded with one protocol access files using another one. This makes perfect sense when you load through http://, and forbid file://. Here, you're loading through jar:file:..., and the webview will only let you access jar:file:... resources (I just tried, I can access an image from another jar file, from the same jar file, but not from outside!).
This sounds very much like a bug to me.
One workaround mentioned here is to use "data:" URI (i.e. encode the image directly in the HTML file).
I am working on an app and I need to save the content of UIWebView.
I currently Use stringByEvaluatingJavaScriptFromString:#"document.getElementsByTagName('html')[0].innerHTML"
to get the html of the UIWebView, but the problem with this method is that it does not save the full content of some webpages.
So my question is How do you save the full content of a webpage including images and css
I think there is already a thread about this topic here:
iphone uiwebview download complete page with CSS and Images
Hope that helps.
When I try to display a local HTML page un a UIWebView, the CSS for that page is not being applied. However, when I load that same page in the regular Safari, it is. What could be causing this?
I assume you are using loadHTMLString to populate the content of the UIWebView? Is your CSS embedded in the HTML that you are loading into the view? If it references a file online, check that the URL file is the full path (not just the relative path).
If the CSS is referenced using a relative path it will work fine in the browser, but not in a UIWebView with statically loaded content.
I found some interesting URL http://cubiq.org/rotating-wheel-for-your-iphone-webapps which has rotational menu. Its good. It has html file along with images, css files etc.
In iPhone app, I copied (to root folder) all the files and imported to project. I'm using UIWebView's load request to load the html. But I'm not getting the rotatable menu.
Can some one post me the code (or tutorial or prototype or example) on how to use it?
Also let me know how to catch the even on click on "OK" button at the middle of the html.
Thanks in advance.
