How can I pass a HTML string markup read from a file in objective C and pass it to a javascript function that takes a parameter ?
In my webViewDidFinishLoad I try to call like this
NSString *jsfile = [[NSBundle mainBundle] pathForResource:@"setcontent" ofType:@"js"];
NSString *js = [NSString stringWithContentsOfFile:jsfile encoding:NSUTF8StringEncoding error:&errDes];
[webView stringByEvaluatingJavaScriptFromString:js];
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"showHtml('%@');", filecontent]];
my javascript file is loaded with a function
function showHtml(param1)
{
alert(param1);
document.getElementById('section1').innerHTML = param1;
}
I tested this piece of code with explicit string values such as @"<p id=\"cid1\"> test </p>" and it works by setting the element contents. If I change this to @"<p id='cid1'> test </p>" i.e. with single quotes to the id attribute, it is not working. In order for the latter to work, I have to change the string formatter '%@' to \"%@\" in objective C code.
the above problem is not that serious but it is not working either way when reading the contents of a resource file containing multiple html tags that has to be set as an innerHTML to the #section1 to a div element.
Do I need to encode the contents somehow ? before calling the stringByEvaluatingJavaScriptFromString method ? Can anyone give me point me, what am I doing wrong ? if anyone know a better way to do this, please write.
Kind regards
