How to deal with quotation

how to deal with this kind of problem

for example:

<img src='abc.jpg' onclick='$("#abc").load("abc.php?value=abc's");'>

the problem is in abc's

 

Change it to:

<img src="abc.jpg" onclick="$('#abc').load('abc.php?value=abc\'s');">

HTML:

This also makes the tag XHTML compliant (if you add a / before >)

 

Including the backwards slash is called "escaping" the character.
