Escaping " and ' characters in Javascript

[NecroJoe]

I am using PHP to generate a little javascript for one of my pages. In
short it allows a user to select a value from a list and pop it into a form
field on a seperate page. This works well unless there is a " or ' in the
character string.

<SCRIPT language=JavaScript>
function Add_Term(SearchTerm) {
window.opener.document.advsearch.name_title.value +=
SearchTerm;
window.close();
}
</SCRIPT>

<a href="javascript:Add_Term('This will work')">"Amarga Presencia"</a>

<a href="javascript:Add_Term('This "won't" work')">"Amarga Presencia"</a>

How do I escape the " and ' characters properly ..? I know this is basic
but I have tried \' and \" and cant think what else to do.

In HTML4, the type attribute is required, and it is always sufficient.
Use:
<script type="text/javascript">
function Add_Term(SearchTerm) {
window.opener.document.advsearch.name_title.value +=
SearchTerm;
window.close();
}
</SCRIPT>

<a href="javascript:Add_Term('This will work')">"Amarga Presencia"</a>
Don't use "javascript:"-URLs. <URL:http://jibbering.com/faq/#FAQ4_24>
<a href="javascript:Add_Term('This "won't" work')">"Amarga Presencia"</a>
No, the HTML attribute is surrounded by "'s, so you can't use them inside
it as well. Use:
---
<a href="javascript:Add_Term('This &quot;won't&quot; work')"> ...
---
(or rather:
---
<a href="needJS.html" onclick="Add_Term('This &quot;won't&quot; work')"> ...
---
)

What you need is the HTML escape, which is &quot; for " and &apos; for '.
If you also need to nest quotes inside the Javascript, then use backslashes
to escape:
----
onclick="foo('ain\'t this &quot;kosher&quot;?');
bar(&quot;No \&quot;dear\&quot;!&quot;);"
---
This is HTML escape for this javascript:
---
foo('ain\'t this "kosher"?');
bar("No \"dear\"!");
---
I know this is basic
but I have tried \' and \" and cant think what else to do.

HTML escapes, not Javascript. :)

Correct, either one won't work ;-)

Use

<a href="javascript:Add_Term('This &quot;won\'t&quot; work')"> ...

or rather

<a href="needJS.html"
onclick="Add_Term('This &quot;won\'t&quot; work')"> ...

instead.
