maximum length onclick attribute in ie

Question

Does anybody know if there is a length limitation for the onclick attribute in IE7? It seems that my onclick value is cut off after 259 chars.

EDIT: Thanks for all your answers. It seems there is not limitation for the onclick attribute. There must be a bug somewhere in my code.

Answer 1

Must be a typo in your value (e.g. unmatched quotes)...

this works fine for me... (1,537 chars)

There is no length limit on these attributes. More likely you are accidentally using a quote inside the attribute to make the whole tag un-parsable as in:

<input type="button" onclick="alert("I'm not quite right.");"/>

You can fix this in two ways:

<input type="button" onclick="alert('I\'m all better now.');"/>
<input type="button" onclick="alert(&quot;I'm all better now.&quot;);"/>
