Calling Javascript using UIWebView

[ashwinr87]

I am trying to call a javascript in a html page using the function -

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writablePath = [documentsDirectory stringByAppendingPathComponent:@"BasicGraph.html"];
NSURL *urlStr = [NSURL fileURLWithPath:writablePath];

NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *myPathInfo = [[NSBundle mainBundle] pathForResource:@"BasicGraph" ofType:@"html"];
[fileManager copyItemAtPath:myPathInfo toPath:writablePath error:NULL];

[graphView loadRequest:[NSURLRequest requestWithURL:urlStr]];
[graphView stringByEvaluatingJavaScriptFromString:@"methodName()"];

Here is the javascript on the html page -

<script>
function methodName()
    {
        alert(hi);
    } 
window.onload = function ()
    {
      // Code Omitted
    }
</script>

However, the function methodName() is not getting called but after window.onload = function () everything is working fine..

I am trying to integrate RGraphs into my application and Basic.html is the html page in which the javascripts are written.

It would be great if someone could help me out with this.

The only obvious issue I see is that you are not waiting for your HTML to finish loading.

You should implement the UIWebViewDelegate method webViewDidFinishLoad and make your javascript call from there.

yes.. that was the problem .. I figured it out in a bit.. Also I had to set the delegate to self..
Thanks for the help..
