Moreover: is it possible to catch a certain type of input (i.e. text or radio)? Thank you!!! ObOnKen 回答1: getElementsByTagName() returns a collection of elements so you need to iterate over the

问题 I'm having troubles fixing a 'broken' html string, using PHP I'm facing the common problem of using substr on an html string, which results in broken tags. I've managed to fix all the broken tags, except the image one, as the tag itself is not complete, it's not even an opening tag, For example, Suppose you have a string: <div><img alt="foo" title="bar" I'd really want to to add a > to close this, and my other scripts know how to close the div automatically.

问题 I have an app with Tags and it works great, but I was wondering if there was a way to restrict the tag cloud to only the MOST POPULAR tags? Right now it looks like it's ordering my cloud by the order in which the tags were created and I have a limit of ten in in my tags_count method inside my MODEL. I used "Tagging" to do it from scratch, and I am not using acts_as_taggable . Controllers: class DailypostsController < ApplicationController def index if params[:tag] @dailyposts = Dailypost

问题 I know next to nothing about RegEx, even after reading a few tutorials :\ I basically just want to know how to replace tags with tags - so how do you match the tag and how do you state that you want to replace it, keeping the tag text as it is? I saw something about a $1 in the replacement string but I don't know what that refers to?

问题 I was following this question on how to retrieve all tags in PHP. Specifically (under wordpress), I'd like to find all <pre> tags , with all the available information (attributes and text). However, it seems that I'm not that skilled in preg_match, so I'm turning to you. My text does contain various <pre> tags, some with attributes, some with just text. My function is this: function getPreTags($string) { $pattern = "/<pre\s?(.*)>(.*)<\/pre>/"; preg_match($pattern, $string, $matches); return

问题 I want to assign suitSize to scrollButton what I'm doing wrong? UIView *scrollButton = [suitScrollView viewWithTag:1]; CGSize suitSize =CGSizeMake(10.0f,10.0f); (UIButton *)scrollButton.frame.size=suitSize; 回答1: frame is a property, not a structure field. You can't assign to a subfield of it. Think of it as a function call; dot syntax for properties is convenience. This: scrollButton.frame.size = suitSize; Is equivalent to: [scrollButton frame].size = suitSize; Which doesn't work; it doesn't
