对于href使用JavaScript单引号和双引号 [英] Using JavaScript single and double quotes for href's

问题描述

我有问题可以在 href 的JavaScript函数中转义单引号和双引号。

I am having problem with escaping the single and double quotes inside the hrefs JavaScript function.

我有 href 中的JavaScript代码。这就像 -

I have this JavaScript code inside href. It's like -

<a href = "javascript:myFunc("fileDir/fileName.doc", true)"> click this </a>

现在，由于双引号内的双引号无效，我需要将内部双引号它被视为字符串的一部分 -
所以，我需要这样做 -

Now, since double quotes inside double quote is not valid, I need to escape the inner double quotes for it to be treated as part of the string - so, I need to do this -

<a href = "javascript:myFunc(\"fileDir/fileName.doc\" , true)"> click this </a>

问题是，即使上述代码不起作用。 JavaScript代码被截断 - myFunc（

The problem is, even the above code is not working. The JavaScript code is getting truncated at -- myFunc(

我尝试过单引号变体，这似乎不起作用（这意味着如果我的字符串中的单引号字面值代码被截断）。

I tried with the single quote variation too - but even that doesn't seem to work (meaning that if I have a single quote inside my string literal then the code gets truncated).

这是我用一个单一的引用：

This is what I did with a single quote:

<a href = 'javascript:myFunc("fileDir/fileName.doc" , true)'> click this </a>

这有效，但是如果我在字符串中有一个单引号，那么代码被截取与双引号一样。

This works, but if I have a single quote inside the string then the code gets truncated in the same way as that of double quotes one.

推荐答案

使用反斜杠来转义引号是如何在JavaScript中工作的，但是您实际上并没有在其中编写JavaScript代码：您正在编写HTML，您可以使用HTML转义方法：字符实体。

Using backslashes to escape quotes is how it works in JavaScript, but you're not actually writing JavaScript code there: you're writing HTML. You can do it by using the HTML escaping method: character entities.

"  // "
'   // '

例如：

<a href="javascript: alert('John O&#39;Brien says &quot;Hi!&quot');">...</a>
