【中文标题】HTML属性可以有撇号吗

【英文标题】：Can HTML attributes have apostrophes

【问题描述】：

由于多种原因，我最终得到了一些需要在 html 属性标签内存储 JSON 序列化对象的代码。

然而，我遇到了一个问题，我的 json 序列化对象之一包含撇号，因此似乎破坏了 jQuery。

基本上这就是行为......

这是表头定义。

这是代码。

var Data = $(GridRow).find(".DraggableRowTable").attr("RowData");
//Data = ""AuthorID":"652c90e4-ffef-49c5-9217-0ff39a461011","Created":"\/Date(1319429903223+1100)\/","EditorID":"652c90e4-ffef-49c5-9217-0ff39a461011","Modified":"\/Date(1319429903223+1100)\/","AssignedToID":"7daef058-d84c-43f5-9db1-8011c59673ee","DetailedTaskID":"169ea939-7cb7-4599-9c2a-9e8ef4dee641","Duration":4.0000,"EndDate":"\/Date(1319497200000+1100)\/","ManualCalculation":false,"RoleID":"944f0ea3-4312-4f14-9d00-c968a647996a","Sequence":14,"StartDate":"\/Date(1319429872333+1100)\/","Status":0,"SubSequence":0,"Task":"AuthorID":"652c90e4-ffef-49c5-9217-0ff39a461011","Created":"\/Date(1319172394650+1100)\/","EditorID":"652c90e4-ffef-49c5-9217-0ff39a461011","Modified":"\/Date(1319172394650+1100)\/","AssignedToID":"7daef058-d84c-43f5-9db1-8011c59673ee","Duration":4,"IsActive":true,"ProductID":"dad82b06-7d28-4255-bf02-f709eeed64cd","RoleID":"944f0ea3-4312-4f14-9d00-c968a647996a","Sequence":14,"TaskDescription":"es reviewer is to review the following fields and provide feedback to the writer if they" //As you can see, it all breaks here...

所以我想我想知道，首先在 HTML 属性中使用撇号是否有效（IE：HTML 标准是否支持这一点），其次（取决于对第一个的答案）jQuery 是否应该能够正确返回此属性？

【问题讨论】：

哇，在很多层面上都错了。我简直无语了。

我讨厌这样的 cmets。而不是仅仅指出有问题的地方，也许您想实际转发一些建设性的东西？

【参考方案1】：

你没有说哪个版本的 HTML，所以我假设 HTML5

除非另有说明，HTML 元素的属性可以有任何字符串值，包括空字符串。除非明确说明，对这些属性中可以指定的文本没有任何限制。

您的问题是您没有编码撇号。您可能需要将出现的' 更改为'。你真的应该对整个字符串进行 HTML 编码。

【讨论】：

我接受您关于 JSON 应该被编码的批评，但是如果标准允许撇号（并且您的段落表明它允许）这是否意味着 jQuery 实现中存在错误？

你有整个标签属性在单引号中；嵌入的单引号必须以某种方式转义，这就是您在 HTML 中使用实体的方式。或者，您可以将属性值放在双引号中，然后实体转义所有双引号，我想。
