帮助在UIWebView中使用Javascript代码 [英] Help Using Javascript Code in a UIWebView

问题描述

我想在webView中运行以下代码，以便内容可编辑：

I would like to run the following code in a webView, so that the content is editable:

javascript: document.body.contentEditable ='true'; document.designMode='on'; void 0

到目前为止我已经尝试过：

So far I have got as far as trying this:

- (void)webViewDidFinishLoad:(UIWebView *)webViews  
{    
    NSString *string = @"javascript: document.body.contentEditable ='true'; document.designMode='on'; void 0";
    [webView stringByEvaluatingJavaScriptFromString:string];
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:string]]];
    NSLog(@"finished load");
}

如果你能告诉我如何获得这个工作将是巨大的。 / p>

If you could tell me how to get this working that would be great.

推荐答案

我喜欢在JavaScript中封装我的JavaScript调用。我的意思是，如果有多行要在JavaScript中运行，将其包装在函数中，并只调用函数。这个分离的逻辑出来干净，让你测试的东西严格在Safari中，而不建立一个iPhone应用程序围绕它。

I like wrapping up my JavaScript calls in JavaScript. What I mean by this is, if there are multiple lines to be run in JavaScript, to wrap that in a function and call just the function. This separates the logic out cleanly and let's you test things strictly in Safari without building an iPhone app around it.

此外，我同意Evan说关于摆脱 [webView loadRequest：。

Also, I agree with what Evan said about getting rid of the [webView loadRequest:.

编辑：通过结束，我的意思是：

By wrapping up, I mean something like:

function foo() { document.body.contentEditable ='true'; document.designMode='on'; }

然后在iOS的调用中调用foo。

And then just calling "foo" in your call from iOS.
