UIWebView and javascript need to load data

Question

I have a file called proof.html like this one:

    <title>{title}</title>
    <link rel="stylesheet" type="text/css" href="{cssURL}" />
    <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" />
    <meta name="apple-mobile-web-app-capable" content="yes" />
</head>
<body class="{language} {custom}">
<div class="FeedTitle">{feedTitle}<br /><span><em>via</em> RSS</span></div>
<div class="Published">{date}</div>
<div class="Title"><a href="{sourceURL}">{title}</a></div>
<div class="Author">{author}</div>
<div class="RSS">{text}</div>
<div class="Original"><a href="{sourceURL}"></a></div>

Later on I am loading it in my UIWebViev using the command below:

 [doc loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"proof" ofType:@"html"]isDirectory:NO]]];

Now I can't understand how I can replace for example {author} with the real name of the autor of my news... How can I pass It to my UIWebView? Can someone share an example? Thanks.

You will need to use JavaScript to do this, with the method stringByEvaluatingJavaScriptFromString:

for example:

[yourWebView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.getElementById('Author').innerHTML = '%@';",authorsName]];

note: for the above example, you will need to add an id attribute to your divs.

mmm I try your code but I can't understand how it works. NSString *author=@"Sample"; [doc stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.getElementById('author').innerHTML = '%@';",author]]; but I'll not able to replace {author] with the "Sample" string.

the document.getElementById('author') will search for the div element in your web page which has an idattribute equal to author. You must change you HTML to <div id="author" class="Author">{author}</div> for it to work

You can change it using javascript.

[webview stringByEvaluatingJavaScriptFromString:@"your js code"];

Above code will evaluate the javascript into ur current page. You can add js code to set the author to ur desired string.
