Quote Help

[HeidiR]

Guys,

The following test code uses the Javascript innerHTML method to change text in a table. The code works correctly if there are no double quotes in the string ($new_str) used by innerHTML. However, the <button> line of code contains both single and double quotes, which causes the innerHTML method to fail. Commenting out the <button> line of code produces the desired results.

Is there a way around this single / double quote issue???

	$str .= "<table border=0>";
	$str .= "<tr><td id='main_page_details_code'>default</td></tr>";
	$str .= "</table>";

echo($str);

sleep(2);

$str = "<table class=tblf width='100%' cellspacing=0 cellpadding=0 border=0>";
	$str .= "<tr><td class=txt12_c>New Text</td></tr>";
$str .= "</table><br>";

$str .= "<button type='button' class=txt12_c onClick=\"window.location='google.com'\">Google</button>";

_main_page_details_code_text_swap($str); //'new text'


function _main_page_details_code_text_swap($new_str){


echo("<script type='text/javascript'>document.getElementById('main_page_details_code').innerHTML=\"" . $new_str . "\"</script>"); 

}

escape them

Thanks for the reply. The button line, which contains the problem double quotes, are already escaped (see below).

$str .= "<button type='button' class=txt12_c onClick=\"window.location='google.com'\">Google</button>";

You must escape your escape character.

[HeidiR]

You mean like onClick=\"\"window.location='google.com'\"\"

[johanafm]

No, your escape character is the character used to escape the quotation mark, i.e. . So, in order to escape it, you put \\". Since \ turns into \ and \" turns into ", you end up with \" which is what you need in your javascript function.

Success. That did it. Thanks for your help!
