阅读更多关于 Dynamically creating a table in Javascript

问题 I have got a working table that when the button is pushed, a table is dynamically created by looping through an array and displaying that data in each cell. However the problem arises when I am trying to add a table header for my table, and I'm not sure what I am doing wrong. Here is my current working code: (although doesn't seem to work in JSFiddle?!)

问题 I would like to replace <includes module="styles" /> with the $styles string at the position where it is. Unfortunately it appends it in the body and not in the head. Anyway, maybe there is another way to realize this issue? $xml = <<<EOD <!DOCTYPE html> <html> <head> <title></title> <includes module="styles" /> </head> <body> <includes module="m1" /> <includes module="m2" /> </body> </html> EOD; $styles = <<<EOD <styles> .m1{ font-size: 12px; font-family: Helvetica, Arial, sans-serif; color:

阅读更多关于 preg_replace vs DOMDocument replaceChild

问题 I was wondering which method mentioned in the title is more efficient to replace content in a html page. I have this custom tag in my page: <includes module='footer'/> which will be replaced with some content. Now there are some downsides with using DOMDocument->getElementsByTagName('includes')->item(0)->parentNode->replaceChild for instance when i forgot to add the slash in the tag, like so <includes module='footer'> the whole site crashes. Regex allows exceptions like these, as long it

Javascript appendChild name property

阅读更多关于 Javascript appendChild name property

问题 So I'm trying to add attributes to a radio button input, specifically the name attribute in Javascript. I'm appending children to a main object and when I use Object.setAttribute("name", value); and subsequently check the innerHTML of the appended input, it does not even contain a name property at all! I'm guessing I'm missing something simple or there is a way around it but I've been wrestling with this problem for quite a while with no success. I tried accessing the property directly using

阅读更多关于 How to use DOMDocument insertBefore

The PHP documentation for insertBefore (http://www.php.net/manual/en/domnode.insertbefore.php) says this is exactly what should happen, but instead of inserting ahead of the existing elements, its replacing all existing elements inside my 'content' div. Here's my code: $webpage = new DOMDocument(); $webpage->loadHTMLFile("news.html");

Number of nodes returned in MutationRecord.addedNodes nodelist (mutationObserver)

阅读更多关于 Number of nodes returned in MutationRecord.addedNodes nodelist (mutationObserver)

问题 MutationRecord.addedNodes returns NodeList with nodes detected as added in my document. When I use obj.appendChild() method, mutationObserver detects it and returns this ONE node in MutationRecord.addedNodes as nodelist [node]. When I use .appendChild() in loop, mutationObserver fires as many times as the number of loops amounts. I'm just wondering if there is any case when mutationOvserver will detect more than one node added simultaneously and fire ONCE and return those nodes in
