getelementsbytagname

getElementsByTagName() has 2 great features: it is fast and it is live. But what if I want to get p strong . Of course I could refine a selection using getElementsByTagName() again but wouldn't I lose the live effect for the new p tags? Is there a way to turn querySelectorAll into a live selector? Or... is there a way to use getElementsByTagName() and getElementsByClassName() to create a function that works in a similar way (at least with descendants) as querySelectorAll but being live? Consider using mutation observers. Watch for childList with subtree: true . When the notification arrives,

Here's my code: Sub www() End Sub 回答1: In line with my earlier answer to this here is how you change the languages. Note: Late binding won't offer you the interface for .querySelector . It has to be with early binding i.e. reference added for HTML Object Library . Additional reference is Microsoft Internet Controls though this doesn't affect .querySelector . To do from and to languages use: .querySelectorAll("button span")(0).innerText =

I keep getting the error message: "Method 'Document' of object 'IWebBrowser2' failed" With the code as is, and if I include the Or part in the waiting check, I get the error "Automation Error The object invoked has disconnected from its clients."

In any other language, I would cast and it would be easy, but after some quick looking, PHP does not have object casting. So what I need to know is how to get a DOMElement object from a DOMNode object. 回答1: You don't need to cast anything, just call the method: $links = $dom->getElementsByTagName('a'); foreach ($links as $link) { $spans = $link->getElementsByTagName('span'); }

To understand more fully what I'm trying to accomplish, let me explain. I build large forms from time to time for things such as property applications, rental listings, detailed medical website user registration forms and such.

However I have tried implementing it on a site that I have built but can not get the fix to work (or any others) on IE8 (the browser which I am working to get compatability with). I am still getting the "Object or Property is not supported" error meaning that the fix is obviously not working. Coming up short for any reasons why this may not be working correctly and unable to find anyone
