如何在 Watir 中获取图像标题属性？

发布于 2024-09-27 23:20:39 字数 844 浏览 2 评论 0原文

给出以下 HTML 代码（我意识到这很糟糕，但这不是我目前可以解决的问题）：

<img height="64" width="64" class='list_item' src="/img/icon/first.jpg" 
title="This is the first item::Completed the item "I did this first"" alt="First" />

给我一个结果 (this is an image.to_s)

name:
type:
id:
value:
disabled:
src:          /img/icon/first.jpg
width:        64
height:       64
alt:          First

注意缺少“title”元素。这实际上并没有改变（缺少标题元素）

如果我获取这些图标之一的父 div 的内容，我会得到类似的内容：

<img class="list_item" I="" did="" this="" first="" src="/img/icon/first.jpg" alt="First">

原始的损坏的 HTML 已被转换为单独的属性，但标题标签似乎已被完全剥离，并且由于它是我需要的标题标签的内容，所以我有点卡住了。

已使用 Firefox 在 Ruby 1.9.2 上的最新 Watir 上尝试过此操作。

完美世界的解决方案：我想获取图像标签的原始传输 HTML，这样我就可以解决愚蠢的双引号问题的“特殊情况”（即破解）。

足够好的解决方案：标题标签的内容。

Given the following HTML code (which, I realise, sucks, but that's not something I can currently solve):

<img height="64" width="64" class='list_item' src="/img/icon/first.jpg" 
title="This is the first item::Completed the item "I did this first"" alt="First" />

gives me a result of (this is an image.to_s)

name:
type:
id:
value:
disabled:
src:          /img/icon/first.jpg
width:        64
height:       64
alt:          First

Note lack of "title" element. This does not actually change (the lack of the title element)

If I get the contents of the parent div of one of those icons, I get something like:

<img class="list_item" I="" did="" this="" first="" src="/img/icon/first.jpg" alt="First">

The broken HTML of the original has been turned into separate attributes somewhere down the line, but the title tag appears to have been stripped completely, and since it's the contents of the title tag I need, I'm a little stuck.

This has been tried with lastest Watir on Ruby 1.9.2 using Firefox.

Perfect world solution: I'd like to get the original transmitted HTML for the image tag, so I can "special case" (ie, hack) around the stupid double-quote problem.

Good Enough Solution: the contents of the title tag.

Watir::Image 上实际上有一个 #title 方法。对于上述不正确的 HTML，输出将如下所示（其中“i”是 Image 对象）：

i.title
=> "This is the first item::Completed the item "

这仅显示标题的一部分。

但是你可以使用 #html，然后用一些魔法从中解析出所有必要的信息：

i.html
=> "<IMG class=list_item title=\"This is the first item::Completed the item \" alt=First src=\"/img/icon/first.jpg\" width=64 height=64 first?? this did I>"

但正如上面其他答案所提到的 - 由于 HTML 不好，你无法正确地得到它。也许还有其他方法可以实现您的更大目标？

There is actually a #title method on Watir::Image. With the above incorrect HTML the output would be like this (where 'i' is the Image object):

i.title
=> "This is the first item::Completed the item "

This shows only part of the title.

But you could use #html and then parse all the necessary information out of it with some magic:

i.html
=> "<IMG class=list_item title=\"This is the first item::Completed the item \" alt=First src=\"/img/icon/first.jpg\" width=64 height=64 first?? this did I>"

But as other answers above have mentioned - you cannot get it out correctly due to the bad HTML. Maybe there's some other way to accomplish your bigger goal you're having?
