如何引用HTML锚点？ [英] How to reference HTML anchor?

问题描述

我通过loadHTMLString将一个HTML字符串加载到UIWebView中。它产生一个很长的网页。加载该字符串后，我需要导航到设置了name属性的HTML锚定标记。在HTML中，我可能有：

I'm loading a string of HTML into a UIWebView through loadHTMLString. It produces a very long webpage. Once that string is loaded, I need to navigate to an HTML anchor tag with its "name" attribute set. In the HTML, I might have:

//3 pages of text here
<a name="go here"></a> lots more text here
//another 3 pages of text here

我需要网页加载后向下滚动到go here。如果用户单击网页内部的链接并加载外部网址，则映射可以正常工作。

I need the webpage to scroll down to "go here" once loaded. The mappings work fine if a user clicks a link inside of the webpage and it loads an external URL. But in this case, I need to initially scroll down an already loaded webpage.

我仍然可以这样执行javascript：

I can still execute javascript like this:

[MyWebView loadHTMLString:dataString baseURL:[NSURL URLWithString:@"http://www.myscheme.com"]]; 
[webView stringByEvaluatingJavaScriptFromString:@"javascriptFunc('param1');"];

但是我需要类似的东西来导航到锚标签。任何建议？

But I need something similar for navigating to the anchor tag. Any suggestions?

推荐答案

您可以通过执行以下操作跳转到已加载的HTML文件中的锚点：

you can jump to an anchor in an already loaded HTML file by doing:

[webView stringByEvaluatingJavaScriptFromString:@"window.location.hash='#foo'"];

这将跳转，sans动画​​。

this will do the jump, sans animation.
